Hi all,
I have radgrid with 'EditMode="EditForms"'.
I am trying to put the grid in 'add new record' mode in page load, to insert a new row into the grid so that user need not click the add new button.
I have tried the below code,grid appears in insert mode ,but insert is not working properly.On clicking 'Insert',Radgrid_InsertCommand is not getting fired.I am trying to keep the add/refresh buttons and paging disabled in Prerender event.Please help me on this.

protected void gvNation_PreRender(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                gvNation.MasterTableView.IsItemInserted = true;
                gvNation.Rebind();
            }
GridPagerItem pagerItem = (GridPagerItem)gvNation.MasterTableView.GetItems(GridItemType.Pager)[1];
            GridCommandItem commandItem = (GridCommandItem)gvNation.MasterTableView.GetItems(GridItemType.CommandItem)[1];
            GridCommandItem commandItem1 = (GridCommandItem)gvNation.MasterTableView.GetItems(GridItemType.CommandItem)[0];
          


            if (gvNation.EditIndexes.Count > 0 || gvNation.MasterTableView.IsItemInserted)
            {
                pagerItem.Enabled = false;
                commandItem.FindControl("PlaceHolder1").Visible = false;
                Button btn = (Button)commandItem1.FindControl("btnAdd");
                btn.Enabled = false;
                Button btnR = (Button)commandItem1.FindControl("btnRefresh");
                btnR.Enabled = false;
                gvNation.AllowFilteringByColumn = false;
           
            }
            else              
            {
                pagerItem.Enabled = true;               
                commandItem.FindControl("PlaceHolder1").Visible = true;
                Button btn = (Button)commandItem1.FindControl("btnAdd");
                btn.Enabled = true;
                Button btnR = (Button)commandItem1.FindControl("btnRefresh");
                btnR.Enabled = true;
                gvNation.AllowFilteringByColumn = true;
            }  
}

Hi,

I reviewed your code and noticed that there is only a button with a CommandName equal to "InitInsert", but this command does not raise the InsertCommand event, the event is raised from a button with CommandName equal to "PerformInsert".

Give this approach a try and check whether you get the desired behavior.

Kind regards,
