Hi, thanks in advance for any help.

I have a page with a RadGrid and it has declared the "OnItemCommand" attribute. On a switch I have the "RowClick" case, where I take in consideration the main ID of the row and then I present details of that element in a bunch of textboxes.

What I need to do is to block UI when the user clicks on the Row while the information is loading. I know that Grid has its own loading Image but everything is still enabled when loading. I need to block because the rows in the gridview have buttons for actions like "view", "edit", "delete" (image buttons with "OnClientClicked" methods defined that open RadWindows as popups).

I am using jquery.blockUI, I am calling it on the codebehind at the "RowClick" case and unBlocking it once all the info is loaded at the end of "Page_Load" but the BlockUI is appearing after the grid loading animation is completed and I want them to happen at the same time.

protected void MainGridView_OnItemCommand(object sender, GridCommandEventArgs e)
{

switch (e.CommandName)

{

case "RowClick":

Page page = HttpContext.Current.Handler as Page;

ScriptManager.RegisterStartupScript(page, page.GetType(), "err_msg", "blockUI();", true); // "blockUI" function has only a call to $.blockUI()

fill_Details(MainGridView.SelectedValue);

break;

case "x":

....

}

So, basically what I need is to be able to execute a javascript function at the same time that the loading image appears on the grid so I can disable any other action while loading is still in progress.

Any comment, suggestion or hint will be highly appreciated.

Thanks & Regards

Oscar
