Use wizard like dialog editing in EJ2 TypeScript Treegrid control
27 Apr 202315 minutes to read
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 editSetting.template as SCRIPT element ID or HTML string which holds the template.
The following example demonstrate the wizard like editing in the Tree Grid with the obtrusive Validation.
import { TreeGrid, Edit, Toolbar } from "@syncfusion/ej2-treegrid";
import { projectData } from './datasource.ts';
import { DropDownList } from "@syncfusion/ej2-dropdowns";
import { DataUtil } from "@syncfusion/ej2-data";
import { DialogEditEventArgs } from "@syncfusion/ej2-grids";
import { NumericTextBox } from "@syncfusion/ej2-inputs";
TreeGrid.Inject(Edit, Toolbar);
let PriorityData: {}[] = DataUtil.distinct(projectData, "Priority", true);
let treegrid: TreeGrid = new TreeGrid({
dataSource: projectData,
idMapping: "TaskID",
parentIdMapping: "parentID",
treeColumnIndex: 1,
height: 273,
toolbar: ["Add", "Edit", "Delete", "Update", "Cancel"],
editSettings: {
allowEditing: true,
allowAdding: true,
allowDeleting: true,
mode: "Dialog",
template: "#dialogtemplate"
},
actionComplete: actionComplete,
columns: [
{ field: "TaskID", headerText: "Task ID", isPrimaryKey: true, textAlign: "Right", width: 70 },
{ field: "TaskName", headerText: "Task Name", width: 100 },
{ field: "StartDate", headerText: "Start Date", textAlign: "Right", width: 90, editType: "datepickeredit",
format: { skeleton: "yMd", type: "date" }, edit: { params: { format: "y/M/d" } } },
{ field: "EndDate", headerText: "End Date", textAlign: "Right", width: 90, editType: "datepickeredit",
format: { skeleton: "yMd", type: "date" }, edit: { params: { format: "y/M/d" } } },
{ field: "Duration", headerText: "Duration", textAlign: "Right", width: 90 },
{ field: "Priority", headerText: "Priority", width: 90 }
]
});
treegrid.appendTo("#TreeGrid");
function actionComplete(args) {
if (args.requestType === "beginEdit" || args.requestType === "add") {
new DropDownList(
{
value: args.rowData.Priority,
popupHeight: "300px",
floatLabelType: "Always",
dataSource: PriorityData,
fields: { text: "Priority", value: "Priority" },
placeholder: "Priority"
},
args.form.elements.namedItem("Priority") as HTMLInputElement
);
new NumericTextBox(
{ value: args.rowData.Duration, placeholder: "Duration" },
args.form.elements.namedItem("Duration")
);
// Set initail Focus
if (args.requestType === "beginEdit") {
(args.form.elements.namedItem("TaskName") as HTMLInputElement).focus();
}
initializeWizard();
}
}
function initializeWizard() {
let currentTab = 0;
document.getElementById("nextBtn").onclick = function() {
if (validate()) {
if (this.innerHTML !== "SUBMIT") {
currentTab++;
nextpre(currentTab);
} else {
treegrid.endEdit();
}
}
};
function validate(tab) {
let valid: boolean = true;
[].slice
.call(
document.getElementById("tab" + currentTab).querySelectorAll("[name]")
)
.forEach(element => {
element.form.ej2_instances[0].validate(element.name);
if (element.getAttribute("aria-invalid") === "true") {
valid = false;
}
});
if (!valid) {
return false;
}
return true;
}
document.getElementById("prevBtn").onclick = function() {
if (validate()) {
currentTab--;
nextpre(currentTab);
}
};
}
function nextpre(current) {
let tabs: HTMLElement[] = [].slice.call(
document.getElementsByClassName("tab")
);
tabs.forEach(element => (element.style.display = "none"));
tabs[current].style.display = "";
if (current) {
document.getElementById("prevBtn").style.display = "";
document.getElementById("nextBtn").innerHTML = "SUBMIT";
} else {
document.getElementById("prevBtn").style.display = "none";
document.getElementById("nextBtn").innerHTML = "NEXT";
}
