Summary

This article describes how to disable a column header either of the root or child tables. In some scenarios, it is useful to display obvious data without displaying its column header, in order to give more space to the important data, or other content.

The OnInitializeLayout server-side event should be used when the Grid layout needs to be initialized during data binding. You can write the code to dynamically add Columns, GroupedColumns, or other objects in this event. First, the data source and data member of the WebGrid must be configured appropriately. By default, the column header of the WebGrid is visible during initialization. In order to disable the column header of the WebGrid, we need to modify the ColumnHeaders property of the WebGrid Table to ColumnVisibility.No.

This article focuses on how to disable the column header either of the root tables or child tables by using the OnInitializeLayout server-side event of WebGrid.

In this article, you will perform the following tasks:

  • Implement the OnInitializeLayout server-side event of WebGrid

Implement the OnInitializeLayout server-side event of WebGrid

The following code needs to be inserted on WebGrid’s OnInitializeLayout Server-side event:

protected void WebGrid1_InitializeLayout(object sender, ISNet.WebUI.WebGrid.LayoutEventArgs e)
{
    // disable the column header of the child table
    WebGrid1.RootTable.ChildTables.GetNamedItem("NameOfTable").ColumnHeaders = ISNet.WebUI.WebGrid.ColumnVisibility.No;
        
    // optionally disable the column header of the root table 
    //WebGrid1.RootTable.ColumnHeaders = ISNet.WebUI.WebGrid.ColumnVisibility.No;
}
