Render other components in a column

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

To render other components in the grid, ensure the following steps:

Step 1:

Initialize the column template for your custom component.

Copied to clipboard
template:`<div>
        <select class="e-control e-dropdownlist">
            <option value="1" selected="selected">Order Placed</option>
            <option value="2">Processing</option>
            <option value="3">Delivered</option>
        </select>
    </div>`

Step 2:

Using the queryCellInfo event, you can render the DropDown component with the following code.

Copied to clipboard
function dropdown(args: QueryCellInfoEventArgs) {
    let ele=args.cell.querySelector('select');
    let drop = new DropDownList({popupHeight: 150, popupWidth: 150});
    drop.appendTo(ele);
}

Change the orientation of the header text

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

Ensure the following steps:

Step 1:

Create a CSS class with orientation style for the grid header cell.

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

Step 2:

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

Copied to clipboard
{ field: 'ShipCity', headerText: 'Ship City', textAlign: 'Center', customAttributes: {class: 'orientationcss'}, width: 80 },

Step 3:

Resize the header cell height by using the following code.

Copied to clipboard
function 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.
}
}

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,

Copied to clipboard
{
params: {
    query: new Query(),
    dataSource: country,
    fields: { value: 'ShipCountry', text: 'ShipCountry' },
    allowFiltering: true
    }
}

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 to create intuitive step-by-step forms to fill. You can achieve the wizard-like editing by using the dialog template feature. It supports your own editing template by defining the editSettings.mode as Dialog and editSetting.template as SCRIPT element ID or HTML string which holds the template.

The following example demonstrates the wizard-like editing in the grid with obtrusive validation.

Using the tab inside the dialog template

You can use the tab component inside the dialog edit UI using the dialog template feature. The dialog template feature can be enabled by defining the editSettings.mode as Dialog and editSetting.template as SCRIPT element ID or HTML string which holds the template.

To include the tab components in the dialog, follow the given 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">
                        <input id="OrderID" name="OrderID" type="text" value=${if(isAdd)} '' ${else} ${OrderID} ${/if} ${if(isAdd)} '' ${else} disabled ${/if} />
                        <span class="e-float-line"></span>
                        <label class="e-float-text e-label-top" for="OrderID">Order ID</label>

            <div class="form-row" >
                <div class="form-group col-md-6">
                    <div class="e-float-input e-control-wrapper">

                        <label class="e-float-text e-label-top" for="CustomerID">Customer ID</label>
                    </div>
                </div>
            </div>
            <button id='next' class='e-info e-btn' style="float: right" type='button'> next</button>
        </div>

        <div id="tab2" style='display: none'>
            <div class="form-row" >
                <div class="form-group col-md-6">
                    <input type="text" name="ShipCountry" id="ShipCountry" value=${if(isAdd)} '' ${else} ${ShipCountry} ${/if} />
                </div>
            </div>
            <div class="form-row">
                <div class="form-group col-md-6">
                    <input type="checkbox" name="Verified" id="Verified" ${if(isAdd)} '' ${else} checked ${/if} />
                </div>
            </div>
            <button id='submit' class='e-info e-btn' style="float: right" type='button'> submit</button>
        </div>
    </div>

Step 2:

To render the tab component, use the actionComplete event of the grid.

Copied to clipboard
let tabObj: Tab = new Tab({
    showCloseButton: false,
    selecting:  (e) => {if(e.isSwiped) {e.cancel = true;} if(e.selectingIndex === 1) {e.cancel = !validate(1)}},
    items: [
        { header: { 'text': 'Details' }, content: '#tab1' },
        { header: { 'text': 'Verify' }, content: '#tab2' },
    ]
});
tabObj.appendTo('#edittab');

The following example demonstrates rendering the tab control inside the edit dialog. The tab control contains two tabs. You can fill the first tab and then navigate to the second tab. The validation for first tab will be done before navigating to the second tab.

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.

The following example demonstrates on Adding a new row when Enter key is pressed in the grid.

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.

Copied to clipboard
document.getElementById('SingleSort').addEventListener('click', () => {
    grid.sortColumn("OrderID","Descending")
});

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

Copied to clipboard
document.getElementById('MultiSort').addEventListener('click', () => {
    grid.sortModule.sortSettings.columns.push({ field: 'ShipCity',  direction: 'Ascending' },{ field: 'ShipName', direction: 'Descending' });
    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.

document.getElementById('SingleClearSort').addEventListener('click', () => {
    let column: Column = grid.sortModule.sortSettings.columns;
    for(let i=0;i < column.length;i++){
        if(column[i].field === "OrderID") {
            column.splice(i,1);
            grid.refresh();
        }
    }
});

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

document.getElementById('MultiClearSort').addEventListener('click', () => {

Foreign Key

Use Edit Template in Foreign Key Column

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

In the following code example, the Employee Name is a foreign key column. When editing, the AutoComplete component is rendered instead of drop-down list.
