I Have a UserControl called TenantList.ascx which contains a slightly modified GridView from DevExpress

  • 0

I Have a UserControl called TenantList.ascx which contains a slightly modified GridView from DevExpress (Web.ASPxGridView). This control makes Callbacks without causing a postback which is exactly what I need. The specific event I need to react on is CustomButtonClicked. I have made my on OnCustomButtonClicked event on the usercontrol TenantList.ascx that fires when the the GridView CustomButtonClicked event fires.

I have an eventhandler on the page where I use the UC. When I debug using VS I can see that I get into the eventhandler as I am suppose to. My Eventhandler looks like this:

    protected void uc_TenantList_CustomButtonCallback(object sender, ASPxGridViewCustomButtonCallbackEventArgs e)     {         Tenant tenant = (Tenant)uc_TenantList.GetGridView().GetRow(e.VisibleIndex);          switch (e.ButtonID)         {             case 'btn_show':                 ShowRow(tenant);                 break;             case 'btn_edit':                 EditRow(tenant);                 break;             case 'btn_delete':                 DeleteRow(tenant.Id);                 break;             default:                 break;         }      }      private void EditRow(Tenant tenant)     {         uc_TenantDetails.SetTenantData(cBLL.GetTenant(tenant.Id));         UpdatePanel1.Update();     }

The EditRow function get’s called and the UserControl TenantDetails.ascx gets filled with data correctly. However the UpdatePanel1.Update(); is not updating the panel where my TenantDetails UserControl is in.

However if i call UpdatePanel1.Update(); from a normal control registered to the ScriptManager it updates just fine.

        protected void Button1_Click(object sender, EventArgs e)         {             uc_TenantDetails.SetTenantData(cBLL.GetTenant(17));             UpdatePanel1.Update();         }

That works without a problem… I am 100% stuck and without any idea of what might be the problem here.

Any suggestion is welcome!!

  1. Okay solved this issue

    What I needed to do was to enable postback on the gridview control inside my usercontrol. Then place the Gridview usercontrol in a updatepanel and still keep the details usercontrol in another updatepanel.

    That way it all worked out. Not impressed by the solution though. Looks a bit ugly.
