Thank you Christian

I am using a TextBox which has Validators inside Footer Template of GridView, which i want to disable on the Click of Link Button Update.

I dont know if i can do this on client side?

And i believe because the txtNewName is inside the GridView i am not getting its ID.
When i am using the script

';

I am getting the Error txtNewName does not exists...

And Thanks for the tips. I will make sure about my spellings and using Firefox to debug my Javascript.

Thanks
Cheers

OK, yes, that won't work. You'd have to do it within an event of the gridview control, the event that create the row with the textbox.

Ah - you can write a custom validator which fires your other validators manually. Then, you can put the validator you want to control in a different group, and only fire it under certain conditions. This involves digging around in the .NET generated javascript, but it's quite doable.

Wow - do you own any books on ASP.NET, or web development ?

Any ASP.NET button will do a refresh, if it's set to do a postback. You can also do it in javascript and HTML.

But there is a difference between a Postback and a first call to a page.
And a refresh is the latter for me, though it's hard to say what a click on the browser refresh will do because it will send the last request again (postback or not).

A refresh will always refresh the last call made, otherwise how can it refresh page state. The way around this is to never show a postback, for a postback to redirect to the same page with URL parameters the restore state. Then a refresh will go to this page, and the page can be written so this performs no actions, it just shows the same state.

The other option is to have a button that links back to the page, which will not postback, but will lose any state derived from postbacks that have occurred.

In the button click event of the Refresh button place the following code

protected void Button1_Click(object sender, EventArgs e)
{
Page.Response.Redirect(Page.Request.Url.ToString(), true);
}

This is kind of useless. The page has already done a refresh, on the button, and it would just finish it's lifecycle without the redirect.

The page has done the refresh part but may be there are somethings to be done when Page.IsPostBack is false.

Obvious question: do you have a web farm?

If yes, do what exception message says. If not, it can be caused by someone (bot) acessing your site with cached (therefore probably invalid) viewstate.

Hi Sebastian,

I think you can take each DataTable from DataSet and use DataTable.Select() command. This will return datarow collection.

Hope this helps

On the client, or the server ? You can do it on the server using regex. I believe javascript also has regex support, but I'm not familiar with it.
