In TreeGrid, we can dynamically update all the inner properties available in column property. And, we can include/exclude the TreeGrid columns dynamically by using “setModel” method. Please find the code example to modify “headerText” and “textAlign” column property. <input type="button" onclick="clickme()" style="margin-bottom:10px" value="Update Column"/>
<div>
<ej:TreeGrid runat="server" ID="Container" ChildMapping="Children">
<Columns>
<ej:TreeGridColumn HeaderText="Task Id" Field="Id" Width="60"/>
<ej:TreeGridColumn HeaderText="Task Name" Field="Name"/>
<ej:TreeGridColumn HeaderText="Start Date" Field="StartDate" TextAlign="Center"/>
<ej:TreeGridColumn HeaderText="Progress" Field="PercentDone" TextAlign="Right" />
</Columns>
</ej:TreeGrid>
</div>
<script type="text/javascript">
//To dynamically change the TreeGrid columns
function clickme() {
var treeObj = $("#Container").data("ejTreeGrid"),
clonedColumns = $.extend([], treeObj.model.columns),
duration = { field: "EndDate", headerText: "End Date", duration: "numericedit" };
clonedColumns[0].headerText = "Id";
clonedColumns[1].headerText = "Name";
clonedColumns[3].headerText = "Percent Done";
clonedColumns[2].textAlign = ej.TextAlign.Right;
clonedColumns[3].textAlign = ej.TextAlign.Center;
//To include new column dynamically
clonedColumns.push(duration);
treeObj.setModel({ "columns": clonedColumns });
}
</script>
The following output is displayed as a result of the above code example.
