gridlayout-afterchanges.png

i made some changes

1. add RadAjaxManagerProxy to the ContentPage

<telerik:RadAjaxManagerProxy ID="Email_RadAjaxManagerProxy" runat="server" >
</telerik:RadAjaxManagerProxy>

2. In Page_PreRender Event i Added The Following Code:

protected void Page_PreRender(object sender, EventArgs e)

{

GridCommandItem Email_Command = (GridCommandItem)Email_RadGrid.MasterTableView.GetItems(GridItemType.CommandItem)[0];

RadToolBar Email_ToolBar = Email_Command.FindControl("Email_ToolBar") as RadToolBar;

RadToolBarItem _Export = Email_ToolBar.FindItemByValue("Export");

ImageButton btn_Export = (ImageButton)_Export.FindControl("btn_Export");

RadAjaxManager.GetCurrent(this.Page).AjaxSettings.AddAjaxSetting(btn_Export, Email_RadGrid);

}

now Export is working but with one problem that the grid layout is changed please check the attached image.

i think this change in the grid layout is because the AjaxManagerProxy. specially in this line:

RadAjaxManager.GetCurrent(this.Page).AjaxSettings.AddAjaxSetting(btn_Export, Email_RadGrid);
