Hi,

I have followed one of your examples from a while ago which has been working in my website for some time. I recently updated the Telerik AJAX controls to Q1-2013, but now the customer cannot add a record on one of the pages.

I have found that the code-behind uses a subroutine to apply an "InputSetting" to the editable control, very similar to this example:

http://www.telerik.com/help/aspnet-ajax/grid-linq-to-sql-manual-crud-operations.html

The way to prevent the "Editor cannot be initialized for column" error is to simply not use the "SetupInputManager" subroutine.

Obviously there was a breaking change made to the Telerik library at some point - what is the new way to replicate the functionality provided in the "SetupInputManager" subroutine (as shown in your examples)?

Thanks in advance!

Same problem here - it occurred immediately after updating to 2013.2.717.40

It's an automaticUpdate grid without autogenerated columns

<telerik:RadGrid AllowAutomaticUpdates="true" DataSourceID="dsLogins" Width="100%" AutoGenerateColumns="False" runat="server"
ID="gridLogins" AllowSorting="True" AllowPaging="True" Skin="Web20">
<MasterTableView EditMode="EditForms" DataSourceID="dsLogins" DataKeyNames="LoginID">
<Columns>
<telerik:GridBoundColumn UniqueName="LastName" HeaderText="Last Name" DataField="LastName">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="FirstName" HeaderText="First Name" DataField="FirstName">
</telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="Email" HeaderText="Email" DataField="Email">
</telerik:GridBoundColumn>
<telerik:GridCheckBoxColumn UniqueName="IsAdmin" HeaderText="Admin?" DataField="IsAdmin">
</telerik:GridCheckBoxColumn>
<telerik:GridCheckBoxColumn UniqueName="Active" HeaderText="Active?" DataField="IsActive">
</telerik:GridCheckBoxColumn>
<telerik:GridDateTimeColumn UniqueName="LastLogin" ReadOnly="true" HeaderText="Last Login" DataField="LastLogin">
</telerik:GridDateTimeColumn>
<telerik:GridEditCommandColumn HeaderText="" ButtonType="ImageButton" UpdateImageUrl="../App_Themes/default/icons/disk.png" UpdateText="Save Changes" EditImageUrl="../App_Themes/default/icons/application_edit.png" CancelImageUrl="../App_Themes/default/icons/application_delete.png" EditText="Edit" CancelText="Cancel"></telerik:GridEditCommandColumn>
</Columns>
<EditFormSettings>
<EditColumn UniqueName="EditCommandColumn1">
</EditColumn>
</EditFormSettings>
</MasterTableView>
</telerik:RadGrid>

Hello Gonzalo,

I am quoting the answer of my colleague.
"This error could occur if you are setting a column editor control ID in the code-behind (as shown in the following help article). If this is the case, please try removing the code where ID of the editor control is set and see if it solves the issue for you. In previous versions of our RadControls, the editor controls were without ID's, but in our latest versions an ID is given to every editor control and changing that ID would lead to the error you are receiving."
