DropdownList SelectedIndexChanged inside Repeater fires up while under UpdatePanel and click another Dropdownlist outside repeater

I have a 2 Dropdownlist outside a repeater (1st ddl will trigger and refresh the content of the repeater, 2nd ddl refresh its list after an item inside the repeater were executed) and a dropdownlist control inside the repeater.i don't have a problem with the 1st dropdownlist but the 2nd dropdownlist when triggered via selectedindexchanged, it also fires up the selectedindexchanged of the dropdownlist inside the repeater. I put up an UpdatePanel on the repeater and on the 2nd dropdownlist but still the error occurs.
How can i trace the step by step execution and also why the selectedindexchanged handler fires up?
Here is the code snippet:

dt.Columns.Add(new DataColumn("RowNumber", typeof(string)));

int count = gvCREInfo.Rows.Count;
DataRow drCurrentRow = null;
UserControl UC1 = (UserControl)(row.Cells[0].FindControl("UC1InserCRE"));

}
When i run this code working fine and i changed the first dropdownlist
it will pull data and bind to the second, like wise third one also.But when i click the add button selected data lost in the first row and second row control added not with data.How to retain existing selected data and load user control along with data it should not loss data event post back.Please help me and sort out this.

It looks like you probably just need to call that JavaScript function that initializes your "Background Stretcher" on each UpdatePanel update (rather than just when the DOM loads). Changing that function to this should do the trick:
function pageLoad() {
$('BODY').bgStretcher({
images: ['images/slide-1.jpg'],
imageWidth: 1600,
imageHeight: 964,
resizeProportionally: true
});
}
Notice that I used function pageLoad() { (should be called on each postback, including AJAX partial postbacks) rather than $(function () { (only called once, when the DOM loads).

so my problem is i want update pageindex value as per click on next and previous button.

This is the solution of my question ,i solved it my self.
Thanks stackoverflow.
int pagetotal = q.Count();
int pagerowcount = (grid.PageIndex * grid.PageSize) + grid.Rows.Count;
PageIdxLabel.Text = ((grid.PageIndex * grid.PageSize) + 1).ToString() + "to " + Convert.ToString(pagerowcount) + "of" + (pagetotal).ToString();

add a onclientclick to gridview pager

Using asp.net and the gridview control with the pager.
How do I add a onclientclick to it, So that it will only page once the onclientclick returns true.
Is this possible as it can be done with a link?
i know I can do this
GridView pager page buttons accessibility
myGridView.Attributes.Add("onClick", "setOKToClose();")
but it addes it to the grid and I want it only added to the pager
Thanks

Convert your pager to template but you will have to make your own logic for showing and managing page index.

Onlink button now you can add onclientclick

This link has a correct answer combined with this answer.
