[Solved] Setting Focus to a Control

[Richard]

Hi

I'm trying to set focus to a control when in add or edit mode in a radgrid using the following code I got from reading existing posts.  I'm using automatic binding and in form editing.

radgridTimesheets.ClientSettings.ClientEvents.OnColumnCreated = "setTimeout(function(){document.getElementById('" + radcomboClient_Task.ClientID + "').focus();},200);"

However,  I receive a page error message stating that "Error: Expected '}'" and I cant see where I'm going wrong as the code looks OK to me.

Thanks

Richard

Hello Richard,

Could you please give us more details about this code? For example where do you place it, and is the combo inside or outside the grid? The implementation seems correct and unfortunately I cannot say for certain what might cause this erroneous behavior.

It is in the onselectedindex changed event for a template radcombo control.  See the code below.

Thanks

Richard

Public Sub radcomboClientEntry_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)

'first reference the edited grid item through the NamingContainer attribute

Dim editedItem As GridEditableItem = CType(CType(sender, RadComboBox).NamingContainer, GridEditableItem)

' set the value of the client task combo

Dim radcomboClient As RadComboBox = CType(editedItem("Client_ID").FindControl("radcomboClientEntry"), RadComboBox)

Dim radcomboClient_Task As RadComboBox = CType(editedItem("Client_Task_ID").FindControl("radcomboClient_Task"), RadComboBox)

' set the value of the client task combo

radcomboClient_Task.Items.Clear()

dsClient_Tasks.SelectParameters(0).DefaultValue = radcomboClient.Items(radcomboClient.SelectedIndex).Value

radcomboClient_Task.DataBind()

If radcomboClient.SelectedIndex >= 0 Then

If radcomboClient_Task.Items.Count > 0 Then

radcomboClient_Task.SelectedIndex = 0

End If

End If

' set focus to the dlient task control

radgridTimesheets.ClientSettings.ClientEvents.OnColumnCreated =

"setTimeout(function(){document.getElementById('" + radcomboClient_Task.ClientID + "').focus();},200);"

End Sub

Hello Richard,

The client events of RadGrid accept only the name of the javascript handler, hence you cannot define the entire method in the way you specified.

If you want to focus the combobox after an item is selected in it, consider intercepting the ItemCreated event and execute the logic as shown here or use the ResponseScript collection of RadAjaxManager/RadAjaxPanel (in case you ajaxified the grid) to evaluate the script which sets the focus.
