Call javascript in aspx.cs with div<%# Eval("variable") %>' as parameter in aspx

I have a collapsible and expandable gridview. When i change the dropdown in my gridview the gridview collapses due to the autopostback that is caused. I need to do a autopostback since I want to populate a second dropdown based on the first dropdown. Is there a way I can expanded it after it is collapsed. I am thinking of calling the javascript but i dont now how to call it since I have little knowledge in javascript. Thank you for your help.
Here is my javascript.
function divexpandcollapse(divname) {
var div = document.getElementById(divname);
var img = document.getElementById('img' + divname);
if (div.style.display == "none") {
div.style.display = "inline";
img.src = "../images/minus.gif";
} else {
div.style.display = "none";
img.src = "../images/plus.gif";
}
}
Here is the code for my indexChanged how can I add the javascript to expand the grid.
protected void OnClosetIndexChanged(object sender, EventArgs e)
{
//Call javascript to reopen gridview
}
And here is my front end
<asp:TemplateField ItemStyle-Width="20px" >
<ItemTemplate>

store details in gidview on button click

In my application I first need to have a button on clicking the button user should see a pop up with labels and text boxes and on clicking the add button which is in modal pop up the data should be added to grid view every thing is done, but if for the first time i enter the details of a person and i click on add button then they are added to gridview, again if i enter details of another person then the details that are in gridview for first person are disappered and in gridview the second person details are displayed.But it should display both the records.Also if i again run the application after some time then the added records are not displayed in gridview that means when i run the application after some time if i have added the records previously thay should be displayed in gridview along with button but only the button is displayed but not gridview how can i display the added records even i run the application any no of times.

carry your gridview inside Panl1 and all your code behind to webform1.cs, delete webform2, you dont need it.

Add item to DropDownList in EditItemTemplate of a Gridview

I am trying to find a way to add an item to a dropdownlist using codebehind or javascript.
the dropdownlist is located within a gridview in the edit item section

</asp:BoundField>
<asp:BoundField DataField="date_added" HeaderText="Date" SortExpression="date_added" ReadOnly="True" ItemStyle-Width="10%">

<asp:TemplateField HeaderText="sold_by" SortExpression="sold_by">

</ItemTemplate>
<ItemStyle Width="10%" />
</asp:TemplateField>

Try to use
function addValues() {
var listBox = document.getElementById("soldby_ddl");
var option = new Option("value", "value");
listBox.appendChild(option);
}
or
function addValues() {
var listBox = document.getElementById("soldby_ddl");
var option = new Option("value", "value");
listBox.options[i++] = option;
}

i have added this line in
<%# Page Language="C#" MaintainScrollPositionOnPostback="true" ...
and also added in webconfig,

getting help from this link,
http://stackoverflow.com/questions/12092150/maintain-scroll-bar-position-of-a-div-within-a-gridview-after-a-postback
One think i wanna mention that "onscroll="SetDivPosition()" in div tag showing me warning that on scroll is not valid attribute for div tag
But after doing all this its not working for me firstly i populate gridview with dropdown when grid populate it shows check box column too in all rows that on checked save check box value in database and post back occurs if i am at bottom of grid it scroll to the top after post back
Hopes for your suggestion
Thanks
