Here is my Grid update function in projects.aspx.cs file :
protected void RadGridProjets_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

        {         
                this.InsertUpdate(sender, e);
        }
protected void InsertUpdate(object sender, Telerik.Web.UI.GridCommandEventArgs e)
        {      
                object editorValueId = null;           
                GridEditableItem editedItem = e.Item as GridEditableItem;          
                GridEditManager editMan = editedItem.EditManager;                                         
               //code to manage project data
         }
When i call EditManager I have the following error :
Telerik.Web.UI.GridBindingException: {"The current EditFormType does not support the requested editing
capabilities."}

Do you have any ideas ?
Thanks in advance

Hello Sylvain,

The error that you are receiving is due to the fact that you are using FormTemplate for your editing and the EditManager could not be used in such scenario, because there is no relationship between the grid columns and the controls within the FormTemplate. When FormTemplate is used, in order to get obtain certain values you will have to manually get reference to each control by using FindControl() from the edit item.

Detailed information on this matter could be found in the following help article:

• Custom Edit Forms

Hope this helps.
