Refreshing ASP.Net GridView Periodically using Timer removes CheckBox selections

rajesh87...

Hi Mudassar,

I am refreshing my gridview every 10 sec using update panel and Timer control.

In timer control i have:

protected void Timer1_Tick(object sender, EventArgs e) { gv1.DataBind(); }

Now i have a checkbox column in the gridview, and select all checkbox also, for functionality of checkboxes i am using javascript like what is explained by this article: http://www.aspsnippets.com/Articles/Implement-check-all-checkbox-functionality-in-ASP.Net-GridView-control-using-JavaScript.aspx

I like this way its simple and fast. but now when gridview refreshes the checkbox selection and others styles disappears.

Now what can i do to keep my selection as it is on gridview refresh. Do i have to stop the gridview refresh on checkbox selection?

Thanks

Since you are binding the Grid your selections will be lost

Why are you refreshing the Grid always?

Solution what I have is to pass the selected rows to some other GridView so that even if the main GridView refreshes other will have the selections

I am refreshing the gridview so that i can see the record added from the end user as soon as possible wothout doing anything.

Personally i am facing many issues due to gridview refreshing so i am looking for an alternative.

What happens in gmail or yahoomail ? is the inbox automatically refreshes and also we can delete multiple mails be checkboxes.

I am looking for something like that.

Thanks
