                <telerik:ImageEditorTool CommandName="FlipVertical" />
                <telerik:ImageEditorTool CommandName="FlipHorizontal" />
                <telerik:ImageEditorToolSeparator />
                <telerik:ImageEditorTool CommandName="Crop" />
                <telerik:ImageEditorTool CommandName="Resize" />
                <telerik:ImageEditorToolSeparator />
                <telerik:ImageEditorTool CommandName="Reset" />
            </telerik:ImageEditorToolGroup>
        </Tools>
    </telerik:RadImageEditor>
    </telerik:RadAjaxPanel>

parent control ascx.cs:

 protected void GridCenters_ItemCommand(object sender,Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.UpdateCommandName || e.CommandName == RadGrid.PerformInsertCommandName)
    { controls_CustomControls_UploadImageControl_Maya ctrl = e.Item.FindControl("UploadImageControl1") as controls_CustomControls_UploadImageControl_Maya;
        if (ctrl.ImageFileName != "")
        {
            //string imageFileName = (e.Item.FindControl("AsyncUpload1") as RadAsyncUpload).UploadedFiles[0].FileName;
            ctrl.SaveImage();
            logo = ctrl.ImageFileName != "" ? ConvertImgToBinary(ctrl.ImageFileName) : null;
        }

        switch (e.CommandName)
        {
 case "Update":
    if(!EntertainmentDataAccess.UpdateCenter(long.Parse(e.CommandArgument.ToString()), centerName, centerType, logo, website, "", isactive, "", mail, tel, Mobile, fax, country, casa, town, street, BuildNb, POB))
                {
                    LblError.Text = "Branch cannot be updated";
                }
                else
                {
                    LblError.Text = "Branch updated successfully";
                    GridEditCommandColumn editColumn = (GridEditCommandColumn)GridCenters.MasterTableView.GetColumn("EDIT");
                    editColumn.Visible = true;

                    GridCenters.DataBind(); // here i'm getting the error
                }
                break;
        }
    }

  • Can you post the full error message? Also, won't you need a `ScriptManager` in the parent form? – nick_w Jan 12 '13 at 08:08
  • my script manager is in the master page and the full error is : Cannot unregister UpdatePanel with ID 'AjaxPanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported. Parameter name: updatePanel – Bassem Assem Alameddine Jan 12 '13 at 08:15
