Custom Text for ContexHeaderMenu

[Viviane]

Hello,

I need to change the text inside the ContextHeaderMenu in  a radgrid.

I have the following code on my Page_Load:

AddHandler RadGridTransmission.HeaderContextMenu.ItemCreated, AddressOf Me.ContextHeaderMenu_ItemCreated

And the following code to change text in the context menu:

Protected Sub ContextHeaderMenu_ItemCreated(ByVal sender As Object, _
ByVal e As RadMenuEventArgs)

If (e.Item.Value = "ColumnsContainer") Then
e.Item.Text = "Show/Hide columns"

ElseIf (e.Item.Level = 2) AndAlso (TryCast(e.Item.Parent, RadMenuItem).Value = "ColumnsContainer") Then
If (e.Item.Value.EndsWith("ReceiverID")) Then
  e.Item.Text = "Source Receiver ID"
End If

End Sub

 

The part that changes the text to "Show/Hide columns" works but the one to change the text for items in "ColumnsContainer" doesn't.

It finds the item, sets the text but does not change when I run the code.

Any idea?

Thanks!

Hello Viviane,

The column names in the menu are generated on client-side based on the HeaderText of a given column. Therefore, we will need to change the text on the client using script logic or modify the HeaderText property of the column.

One approach to achieve this requirement is using this approach:

Copy Code

protected void RadGrid1_DataBound(object sender, EventArgs e)
{
    GridColumn col = RadGrid1.MasterTableView.GetColumn("ShipName");
    col.HeaderText = "Source Ship Name";
    GridHeaderItem item = RadGrid1.MasterTableView.GetItems(GridItemType.Header)[0] as GridHeaderItem;
    item[col.UniqueName].Text = "Ship Name";
}

Alternatively, you can use the following solution:

Copy Code

<HeaderContextMenu OnClientLoad="headerContextMenuLoad">
</HeaderContextMenu>

JavaScript:

Copy Code

function headerContextMenuLoad(sender, args) {
    var item = sender.findItemByText("ShipName");
    if (item) {
        $(item.get_element()).find("label").text("Source Ship Name");
    }
}

I've prepared a sample RadGrid web site to demonstrate that these suggestions work as expected. I'm also sending another application to demonstrate a more advanced scenario.

I hope this will prove helpful.
