Column ReadOnly true at EditMode but false at InsertMode

Hi all,

I want to set a column to ReadOnly=True at EditMode, but at InsertMode ReadOnly=False. Please advise how to do it.
I did as below but it didn't work. Please help.

Private Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand

If e.CommandName = RadGrid.EditCommandName Then

Dim editItem As GridEditableItem = CType(RadGrid1.MasterTableView.GetItems(GridItemType.EditItem)(0), GridEditableItem)

For Each column As GridColumn In RadGrid1.MasterTableView.Columns

If column.UniqueName = "POL" Then

Dim txtbox As TextBox = CType(editItem (column.UniqueName).Controls(0), TextBox)

txtbox.ReadOnly = True

End If

Next

End If

End Sub

But I got error "Index was outside the bounds of the array." at the below code ..

If e.CommandName = RadGrid.EditCommandName Then

Dim editItem As GridEditableItem = CType(RadGrid1.MasterTableView.GetItems(GridItemType.EditItem)(0), GridEditableItem)

Many Thanks

Simple VB example with Objects

We’re evaluating using the Gantt component for a very large
project; we did not use it before, but extremely familiar with the other
components. It seems this one is missing a few things from the smart Tag, like
data source selection and maybe one day a designer for it. We are a little lost
inside of it and for some crazy reason could not get the examples to work in
VB. Would it be possible to help us with a very simple example that builds the
entire chart from code behind and uses Objects and not a direct connection to
db or a SQL dataset. If possible, please use a FOR loop to insert the Tasks and
relationships. Thank you for the help.

RadDropdownTree.Selected Value cannot be assigned to

Hi,

I'm trying to pre-check all checkboxes with a RadDropdownTree control after it has been bound to (as per the sample code here) but I am getting a 'RadDropDownTree.SelectedValue' cannot be assigned to -- it is read only' error.

I've had a look about online to check for a versioning issue but couldn't see anything - I'm currently using release 2013.1.403.35, is this the issue?

Thanks,
Allan

AjaxToolKit 15.1 and Telerik Controls

Hi,

We've discovered compatibility issues with the new version of AjaxToolKit (15.1)
And your Controls.

When putting some of the controls (i.e RadDatePicker) in a page that uses the
New AjaxToolKit, an error occurred (attached a screenshot).

Please note that this is the new version AjaxToolKit that uses the regular
ScriptManager from Microsoft (no longer ToolkitScriptManager) so all
the documenations you have on this are irrelevant for the new version.

Any suggestions ?

Stepping

Hi,

I am trying various methods for adjusting the minor grid line step value and each one fails. What is the current JS that I could use to change the minorgridline step value?

Sample code that I have been trying is shown below.

Regards

Jon

var kendoWidget = $find("<%=uxRadHtmlChart.ClientID%>").get_kendoWidget();

kendoWidget._plotArea.valueAxis.options.minorGridLines.step = 10;

kendoWidget._plotArea.valueAxis.options.minorUnit = 10;

kendoWidget.redraw();
