Enable/Disable Grid and its actions

You can enable/disable the Grid and its actions by applying/removing corresponding CSS styles.

To enable/disable the grid and its actions, follow the given steps:

Step 1:

Create CSS class with custom style to override the default style of Grid.

    .disablegrid {
        pointer-events: none;
        opacity: 0.4;
    }
    .wrapper {
        cursor: not-allowed;
    }

Step 2:

Add/Remove the CSS class to the Grid in the click event handler of Button.

    public btnClick():void {
      if (this.Grid.element.classList.contains('disablegrid')) {
          this.Grid.element.classList.remove('disablegrid');
          document.getElementById("GridParent").classList.remove('wrapper');
      }
      else {
          this.Grid.element.classList.add('disablegrid');
          document.getElementById("GridParent").classList.add('wrapper');
      }
    }

In the below demo, the button click will enable/disable the Grid and its actions.

Columns

Change Column Header Text Dynamically

You can change the column headerText dynamically through an external button.

Follow the given steps to change the header text dynamically:

Step 1:

Get the column object corresponding to the field name by using the getColumnByField method. Then change the header Text value.

let column = this.grid.getColumnByField('ShipCity'); // Get column object.
column.headerText = 'Changed Text';

Step 2:

To reflect the changes in the grid header, invoke the refreshHeader method.

this.grid.refreshHeader();

Customize Column Styles

You can customise the appearance of header and content of the particular column using the customAttributes property.

To customize the grid column, follow the given steps:

Step 1:

Create a css class with custom style to override the default style for rowcell and headercell.

.e-grid .e-rowcell.customcss{
    background-color: #ecedee;
    color: 'red';
    font-family: 'Bell MT';
    font-size: 20px;
}

.e-grid .e-headercell.customcss{
    background-color: #2382c3;
    color: white;
    font-family: 'Bell MT';
    font-size: 20px;
}

Step 2:

Add the custom css class to particular column by using customAttributes property.

Custom Tooltip for Columns

You can achieve the custom tooltip(EJ2 Tooltip) for Grid by using the queryCellInfo event.

Render the ToolTip component for the grid cells by using the following code in the queryCellInfo event.

tooltip (args: QueryCellInfoEventArgs) {
    let tooltip: Tooltip = new Tooltip({
        content: args.data[args.column.field].toString();
    }, args.cell);
}

Render other components in a column

You can render any component in a grid column using the template property.

Initialize the column template for your custom component. The template property renders the custom component.

    <div>
        <ejs-dropdownlist value='Order Placed' [dataSource]='dropData' [popupHeight]='150' [popupWidth]='150' ></ejs-dropdownlist>

Change the Orientation of Header Text

You can change the orientation of the header text by using the customAttributes property.

To change the Orientation of Header Text, Ensure the following steps:

Step 1:

Create a css class with orientation style for grid header cell.

.orientationcss .e-headercelldiv {
    transform: rotate(90deg);
}

Step 2:

Add the custom css class to particular column by using customAttributes property.

    <e-column field='Freight' headerText='Freight' textAlign='Center' format='C2' [customAttributes]='customAttributes' width=80></e-column>

Step 3:

Resize the header cell height by using the following code.

setHeaderHeight(args) {
    let textWidth: number = document.querySelector('.orientationcss > div').scrollWidth;//Obtain the width of the headerText content.
    let headerCell: NodeList = document.querySelectorAll('.e-headercell');
    for(let i: number = 0; i < headerCell.length; i++) {
        (<HTMLElement>headerCell.item(i)).style.height = textWidth + 'px'; //Assign the obtained textWidth as the height of the headerCell.
    }
}

Customize the icon for column menu

You can customize the column menu icon by overriding the default grid class .e-icons.e-columnmenu with a custom property content as mentioned below.

.e-grid .e-columnheader .e-icons.e-columnmenu::before {
              content: "\e941";
      }

In the below sample, grid is rendered with a customized column menu icon.

Show or Hide columns in Dialog editing

You can show hidden columns or hide visible column’s editor in the dialog while editing the grid record using actionBegin and actionComplete events.

In the actionBegin event, based on requestType as beginEdit or add. We can show or hide the editor by using column.visible property.

In the actionComplete event, based on requestType as save. We can reset the properties back to the column state.

In the below example, we have rendered the grid columns CustomerID as hidden column and ShipCountry as visible column. In the edit mode, we have changed the CustomerID column to visible state and ShipCountry column to hidden state.

Provide custom data source and enabling filtering to DropDownList

You can provide data source to the DropDownList by using the columns.edit.params property.

While setting new data source using edit params, you must specify a new query property too for the DropDownList as follows,

{
    this.countryParams = {
        params:   {
            allowFiltering: true,
            dataSource: this.country,
            fields: {text:'countryName',value:'countryName'},
            query: new Query(),
            actionComplete: () => false
            }
        }
}

You can also enable filtering for the DropDownList by passing the allowFiltering as true to the edit params.

In the below demo, DropDownList is rendered with custom Datasource for the ShipCountry column and enabled filtering to search DropDownList items.

Use Wizard like Dialog Editing

Wizard helps you create intuitive step-by-step forms to fill. You can achieve the wizard like editing by using the dialog template feature. It support your own editing template by defining editSettings.mode as Dialog and editSettingsTemplate as template variable to define the editors.

Using Tab Inside the Dialog Editing

You can use Tab component inside dialog edit UI using dialog template feature. The dialog template feature can be enabled by defining editSettings.mode as Dialog and editSettingsTemplate as template variable to define the editors.

To include tab components in the Dialog, please ensure the following steps:

Step 1:

Initialize the template for your tab component.

        <div id="tab1">
        <div class="form-row">
            <div class="form-group col-md-6">
                <div class="e-float-input e-control-wrapper" [ngClass]="{'e-error': OrderID.invalid && (OrderID.dirty || OrderID.touched)}">
                    <input [(ngModel)]="data.OrderID" required id="OrderID" name="OrderID" type="text" [attr.disabled]="!data.isAdd ? '' : null" #OrderID="ngModel">
                    <span class="e-float-line"></span>
                    <label class="e-float-text e-label-top" for="OrderID"> Order ID</label>
                </div>

                <div class="e-float-input e-control-wrapper" [ngClass]="{'e-error': CustomerID.invalid && (CustomerID.dirty || CustomerID.touched)}">
                    <input [(ngModel)]="data.CustomerID" required id="CustomerID" name="CustomerID" type="text" #CustomerID="ngModel">

                </div>
            </div>
        </div>
        <button ejs-button type="button" cssClass="e-info e-btn" style="float: right" (click)="nextBtn($event)" >next</button>
    </div>

    <div id="tab2" style='display: none'>
        <div class="form-row" >
            <div class="form-group col-md-6">
                <ejs-dropdownlist id="ShipCountry" name="ShipCountry" [(ngModel)]="data.ShipCountry" [dataSource]='shipCountryDistinctData' [fields]="{text: 'ShipCountry', value: 'ShipCountry' }" placeholder="Ship Country" popupHeight='300px' floatLabelType='Always'></ejs-dropdownlist>

        <div class="form-row">
            <div class="form-group col-md-6">
                <ejs-checkbox #Verified name="Verified" id="Verified" label="Verified" [checked]="data.Verified" ></ejs-checkbox>
            </div>
        </div>
        <button ejs-button type="button" cssClass="e-info e-btn" style="float: right" (click)='submitBtn($event)'>submit</button>
    </div>

Step 2:

To render the Tab component, use the editSettingsTemplate of the Grid.

    <ejs-tab #tab id="tab_wizard" showCloseButton=false (selecting)='selecting($event)'>
        <e-tabitems>
            <e-tabitem [header]="{ 'text': 'Details' }" content="#tab1"></e-tabitem>
            <e-tabitem [header]="{ 'text': 'Verify' }" content="#tab2"></e-tabitem>
        </e-tabitems>
    </ejs-tab>

The following example, we have rendered tab control inside the edit dialog. The tab control has two tabs and once you fill the first tab and navigate to second one. The validation for first tab was done before navigate to second.

Disable editing for a particular row/cell

You can disable the editing for a particular row by using the actionBegin event of Grid based on requestType as beginEdit.

In the below demo, the rows which are having the value for ShipCountry column as “France” is prevented from editing.

Perform Grid actions by keyboard shortcut keys

Using keyboard shortcuts, Grid performs navigation and actions.

In addition, You can also perform grid actions with custom keyboard shortcuts. This operation has to be achieved outside of the grid with the help of keydown event.

Sort

Perform single/multi sorting dynamically

You can perform single-column or multi-column sorting dynamically through an external button.

To perform single-column sorting, use the sortColumn method of Grid.

    public SingleSort():void {
      this.grid.sortColumn("OrderID","Descending")
    }

To perform multi-column sorting, you need to push the columns to be sorted into the sortSettings.columns.

    public MultiSort():void {
        this.grid.sortSettings.columns.push({ field: 'CustomerID',  direction: 'Ascending' },{ field: 'ShipName', direction: 'Descending' });
        this.grid.refresh();
    }

In the below demo, click on the corresponding button to perform single-column or multi-column sorting.

Dynamically clear sort for particular/entire sorted columns in Grid

You can clear the sorting for a particular column or the entire sorted columns in Grid dynamically through an external button.

To clear sort for a particular column, you need to splice the particular column from the sortSettings.columns.

    public SingleClearSort():void {
        let column: any = this.grid.sortSettings.columns;
        for(let i=0;i < column.length;i++) {
            if(column[i].field == "OrderID") {
                column.splice(i,1);
                this.grid.refresh();
            }
        }
    }

To clear sorting for all the sorted columns, use the clearSorting method of Grid.

    public MultiClearSort():void {
        this.grid.clearSorting();
    }

In the below demo, click on the corresponding button to clear sort for particular or entire sorted columns in Grid.

Foreign Key

Use Edit Template in Foreign Key Column

By default, foreign key column uses dropdown component for editing. You can render other than the dropdown by using the column.edit property. The following example demonstrates the way of using edit template in foreign column.

In the following example, The Employee Name is a foreign key column and while editing, AutoComplete component is rendered instead of DropDownList.

Customizing filter menu operators list

You can customize the default filter operator list by defining the filterSettings.operators property. The available options are:

  • stringOperator- defines customized string operator list.
  • numberOperator - defines customized number operator list.
  • dateOperator - defines customized date operator list.
  • booleanOperator - defines customized boolean operator list.

In the following sample, we have customized string filter operators.

Exporting

Exporting Grid in Cordova application

Cordova application does not support direct file download. So we have to use the Blob stream to export the Grid. You can use corresponding exporting methods and exportComplete events to get the Blob stream.

Exporting Filtered Data Only

You can export the filtered data by defining the resulted data in exportProperties.dataSource before export.

In the below Pdf exporting demo, We have gotten the filtered data by applying filter query to the grid data and then defines the resulted data in exportProperties.dataSource and pass it to pdfExport method.

Hide the expand/collapse icon in parent row when no records in child grid

By default, the expand/collapse icon will be visible even if the child grid is empty.

You can use rowDataBound event to hide the icon when there are no records in child grid.

To hide the expand/collapse icon in parent row when no records in child grid, follow the given steps:

Step 1:

Create CSS class with custom style to override the default style of Grid.

    .e-row[aria-selected="true"] .e-customizedExpandcell {
        background-color: #e0e0e0;
    }

    .e-grid.e-gridhover tr[role='row']:hover {
        background-color: #eee;
    }

Step 2:

Add the CSS class to the Grid in the rowDataBound event handler of Grid.

    public rowDataBound(args:any){
        let filter:string = args.data.EmployeeID;
        let childrecord: any = new DataManager(this.Grid.childGrid.dataSource).executeLocal(new Query().where('EmployeeID', 'equal', parseInt(filter), true));
        if(childrecord.length == 0) {
            //here hide which parent row has no child records
            args.row.querySelector('td').innerHTML=' ';
            args.row.querySelector('td').className = 'e-customizedExpandcell';
        }
    }

In the below demo, the expand/collapse icon in the row with EmployeeID as 1 is hidden as it does not have record in child Grid.
