ItemDataBound Event

Fired after an item is databound to the RadGrid control.

Examples

Customizing auto-generated columns

If you need to customize the cells of a given column and you do not know the UniqueNames of the columns, you could loop through the AutoGeneratedColumns collection of the current GridTableView and pick the UniqueName of each column fulfilling a given condition and use it to access a cell in the current row. That can be achieved in the ItemDataBound event.

Event Parameters

• (object) sender

  • The control that fires the event

• (GridItemEventArgs) e

  • Event arguments

    • (boolean) e.Canceled

      Set to true to cancel the default event execution, if available. The ItemDataBound event cannot be cancelled.

    • (GridItemEventInfo) e.EventInfo

      Event info object. Cast to derrived classes to obtain appropriate instance.

    • (GridItem) e.Item

      Gets the GridItem which fired the event.

Attaching the event

In the Markup

<telerik:RadGrid ID="RadGrid1" runat="server" OnItemDataBound="RadGrid1_ItemDataBound">
</telerik:RadGrid>

In the Code behind

protected void Page_Init(object sender, EventArgs e)
{
    RadGrid1.ItemDataBound += RadGrid1_ItemDataBound;
}

Protected Sub Page_Init(sender As Object, e As EventArgs) Handles Me.Init
    AddHandler RadGrid1.ItemDataBound, AddressOf RadGrid1_ItemDataBound
End Sub

The event handler

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    bool canceled = e.Canceled;
    GridItemEventInfo eventInfo = e.EventInfo;
    GridItem item = e.Item;
}

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
    Dim canceled As Boolean = e.Canceled
    Dim eventInfo As GridItemEventInfo = e.EventInfo
    Dim item As GridItem = e.Item
End Sub

Examples

Customizing auto-generated columns

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = e.Item as GridDataItem;
        foreach (GridColumn col in RadGrid1.MasterTableView.AutoGeneratedColumns)
        {
            if (col.DataType == typeof(int))
            {
                item[col.UniqueName].Font.Bold = true;
            }
        }
    }
}

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        Dim item As GridDataItem = TryCast(e.Item, GridDataItem)
        For Each col As GridColumn In RadGrid1.MasterTableView.AutoGeneratedColumns
            If col.DataType Is GetType(Integer) Then
                item(col.UniqueName).Font.Bold = True
            End If
        Next
    End If
End Sub
