EditFormType does not support editing

[david]

Hi,

In my editform (itemDatabound) I am trying to populate a dropdownlist thusly:

if

 

(e.Item is GridEditFormItem && e.Item.IsInEditMode)

 

{

 

GridEditFormItem item = (GridEditFormItem)e.Item;

 

 

GridEditableItem editedItem = e.Item as GridEditableItem;

 

 

GridEditManager editMan = editedItem.EditManager;

 

 

GridDropDownListColumnEditor editor = editMan.GetColumnEditor("NumericGrade") as GridDropDownListColumnEditor;

 

 

DropDownList ddlist = editor.DropDownListControl;

 

here is the error, I'm not sure what to do?

The current EditFormType does not support the requested editing capabilities.

Hi David,

I was able to replicate this issue when I set the  EditFormType property of the Grid to Template/WebUserControl. Try setting it to AutoGenerated and see whether the exception is comming.

ASPX:

 <EditFormSettings EditFormType="AutoGenerated" >
                    </EditFormSettings>

Is there a way for this to work without having "AutoGenerated"?  I am using this line "<EditFormSettings EditFormType="Template" >" and i get the error mentioned above.  It does work if i use "AutoGenerated" however I lose my formatting of columns.  They are just listed in a stack and this does not look very good.  ANy ideas?  Thanks.

Hello Stacy,

When EditFormType is "Template", you can supply a template(custom edit form) that the table view uses to generate the edit form. That means you cannot access the control in built- in edit form. One option is you can set EditFormType as "Template" and use controls similar to that in built-in edit form( Eg: Use DropDownList in custom edit form for the GridDropDownColumn in Radgrid).

ASPX:

<FormTemplate>
     <asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource1"
        DataTextField="Name" DataValueField="Name">
     </asp:DropDownList>
</FormTemplate>

And from code behind access the DropDownList using FindControl method.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
       {
           GridEditFormItem item = (GridEditFormItem)e.Item;
           DropDownList drlist = (DropDownList)item.FindControl("DropDownList1");
       }
   }

Thanks,
Princy.
