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>
<a href="JavaScript:divexpandcollapse('div<%# Eval("componente_id") %>');" >

Pop-up Modal on View button from GridView

I have a grid with recordds being retrieved from a database. As part of my grid I have a View button.
When I click on the View link button I want a pop up to open which will be displaying the records in a form.
My problem is that when I click on the View link button the pop up modal does not open.

The LinkButton control causes a postback via javascript, and subsequently a server side click event. The postback is probably what is causing the problem.
I would recommend trying a plain HTML <a> element in your ItemTemplate, or <asp:HyperLink> if you need to manipulate it server side (as well as firing the client click event handler).

Bootstrap has an api for that. You don't need to programatically open it with the event handler. Add data-toggle to your buttons. And then attach the modal id to the href tag of that button. And, change your LinkButton to a regular a tag:
<a style="color:pink" data-toggle="modal" href="#myModal">View</a>
Then, to close it, attach the same attributes to your close button:
<div id="myModal" class="modal">
<!-- Modal content -->
<div class="modal-content">
<div class="modal-header">
<span class="close">×</span>
<h2>Modal Header</h2>
</div>
<div class="modal-body">
<p>Some text in the Modal Body</p>
<p>Some other text...</p>
</div>
<div class="modal-footer">
<h3>Modal Footer</h3>
<a class="btn btn-default prev pull-left" data-toggle="modal" href="#myModal">Cancel</a>
</div>

ASP.NET GridView inside UpdatePanel doesn't update until second click

I've looked for answers online but I have not found any answer. I have a GridView inside an UpdatePanel and one Linkbutton column to show some detail in a Bootstrap modal. I had a problem that when the user clicks on the LinkButton the event OnClick doesn't fire, so, to solve that I made a fuction in Javascript that only causes a click in another LinkButton to fire the OnClick event.
Now it works fine, but nothing changes until the second click.
ASP.NET code

{
SqlDTSgetTracing.SelectParameters["ord_id"].DefaultValue = ((LinkButton)sender).Text;
SqlDTSgetTracing.Select(DataSourceSelectArguments.Empty);
grvLog.DataBind();
upLog.Update();
}
When clicking the first time
When clicnking the seccond time
After clicking twice now the data is displayed in the GridView.
I want that from the first click the data being displayed in the GridView.

I think you might want to append return false; to the end of OnClientClick to prevent the rest of that control's click event (coded by ASP.NET for you) from running. That will ensure only the LinkButton you care about will postback.
OnClientClick="ActivityLog(this);return false;"
Not sure if that will fix the need for clicking twice or not, but maybe!

how to set value for asp Textbox inside jquery modal by row in gridview

I have a problem regarding textbox(tb) inside jquery modal, inside the gridview. Basically, the problem is that the value of the tb same as I click the modal from other row in gridview even I put "tr" to set the row. The key are 'id_rN' and 'rN'. The situation is:
Click modal link for row 1 in gridview
Insert data in tb in modal (eg: hello)
Close modal
Click modal link for row 2 in gridview and the value is same as row 1
I will show the picture of it:
Click "Add/Edit" at 'Remarks' column to show modal pop
Modal Textbox row1 show 'hello'
You can see that modal tb get same value both row1 and row2.
This is the script:
$('a[data-toggle=modal]').click(function () {
var data_pN = String($(".pN", $(this).closest("tr")).html());
var data_cN = String($(".cN", $(this).closest("tr")).html());
var data_aN = String($(".aN", $(this).closest("tr")).html());
var data_rN = $('#<%=GridView1.ClientID %>').find('[id*="id_rN"]', $(this).closest("tr")).val(); //variable for textbox in modal
$('input[id*="id_pN"]').val(data_pN);
$('input[id*="id_cN"]').val(data_cN);
$('input[id*="id_aN"]').val(data_aN);
$('[id*="rN"]', $(this).closest("tr")).val(data_rN); //get value from texbox modal to textbox for column 'Remarktest'
});
This is the gridview html:

Try something like this
HTML MARKUP:
Add a class toyour textbox:
<asp:TextBox ID="id_pN" runat="server" CssClass="cls_pN form-control" ReadOnly="true" Font-Size="Smaller"></asp:TextBox>
<asp:TextBox ID="id_cN" runat="server" CssClass="cls_cN form-control" ReadOnly="true" Font-Size="Smaller"></asp:TextBox>
JQUERY:
$('a[data-toggle=modal]').click(function () {
var self=$(this);
var selfTR=self.closest('tr');
// get current row textbox value
var txt_p=selfTR.find(".cls_pN").val();
var txt_c=selfTR.find(".cls_cN").val();
alert(txt_p);
alert(txt_c);
});

and at the end of the page load event i am using,
Page.ClientScript.RegisterStartupScript(GetType(), "MyKey", "SetDivPosition();", true);
i have added this line in
<%# Page Language="C#" MaintainScrollPositionOnPostback="true" ...
and also added in webconfig,
<system.web>
<pages maintainScrollPositionOnPostBack="true" >
</pages>
</system.web>
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
