How to customize the column properties in ASP.NET MVC Treegrid?
1 min read
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.
<button onclick="clickme()" style="margin-bottom:10px">Update Column</button>
@(Html.EJ().TreeGrid("TreeGridContainer")
.Columns(co =>
{
co.Field("taskID").HeaderText("Task Id").Width(60).Add();
co.Field("taskName").HeaderText("Task Name").Add();
co.Field("startDate").HeaderText("Start Date").TextAlign(TextAlign.Center).Add();
co.Field("progress").HeaderText("Progress").TextAlign(TextAlign.Right).Add();
})
)@(Html.EJ().ScriptManager())
<script type="text/javascript">
//To dynamically change the TreeGrid columns
function clickme() {
var treeObj = $("#TreeGridContainer").data("ejTreeGrid"),
clonedColumns = $.extend([], treeObj.model.columns),
duration = { field: "duration", headerText: "Duration", 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.
