Button click not working inside gridview inside updatepanel

I have a div that has a gridview inside an updatepanel, that I use bootbox.js to show modal.
Inside the gridview is an itemtemplate with an asp.net button "Button1" which I need to click to edit the row after modalpopup but this doesnt fire
Please what am I missing
<div id="userForm" class="form-horizontal" style="display:none;width:100%;border:solid 0px;" >
<input ID="btnshowRun" type="button" Value="Show Leave" class="btn btn-warning " style="float:lefts;" OnClick ="showhide();"/>
<asp:UpdatePanel ID="UpdatePanel5" runat="server" style="display:none;">
<ContentTemplate>
<asp:GridView ID="GridView2" runat="server" AllowSorting="False"

</asp:TemplateField>
</Columns>
<HeaderStyle HorizontalAlign="Center" Font-Bold="True" ForeColor="Black"></HeaderStyle>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</div>

The problem with modals is that they usually place the contents outside of the <form> tag. And then the Buttons do not work anymore.
Replace the Buttons with LinkButtons. They perform a PostBack with JavaScript and will work from a Modal.

I wasnt handling rowediting event hence I was getting an error when I checked the developer view in firefox.Now it fires for me to edit but its after the second click of the link button before it enables the editing.Any ideas?

How to prevent a GridView to resize (ASP)

I have an ASP:Gridview whose Columns might change visibility depending of users clicks.
I would like the layout not to resize when controls visibility changes.
Here is the Gridview code:
<asp:TemplateField HeaderText="Name" HeaderStyle-HorizontalAlign="Right">
<ItemStyle HorizontalAlign="Left" Wrap="False" Font-Size="Small" />
<HeaderStyle HorizontalAlign="Right" CssClass="text-align:right" Font-Size="XX-Small" />
<ItemTemplate>
<asp:Label ID="Label_Name" runat="server" Text='<%# Bind("Name") %>' Width="150" Height="10" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="doc ">
<ItemStyle HorizontalAlign="Center" Wrap="False" Font-Size="Small" />
<ItemTemplate>
<asp:CheckBox ID="CB_Doc" runat="server" Checked='<%# Bind("MyProp") %>' Width="50px" AutoPostBack="true" OnCheckedChanged="CB_CheckedChanged" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Book">
<ItemStyle HorizontalAlign="Left" Wrap="False" Font-Size="XX-Small" />
<ItemTemplate>
<asp:HiddenField runat="server" ID="HF_Id" Value='<%# Bind("Id") %>' />
<table>
<tr>
<td style="padding-left: 50px;">
<asp:CheckBox ID="CB_Book" runat="server" Checked='<%# Bind("MyProp2") %>' Width="30" AutoPostBack="true" OnCheckedChanged="CB_CheckedChanged" />
</td>
<!-- A few more controls that might be visible or not depending if user clicks previous CheckBox -->
</tr>
</table>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Default it displays this way:
When I click on the right Checkbox, the GridView has the bad idea to resize this way:
Is there a way to prevent this resizing?
As far as I can see, there would definitely be enough space to display all of the controls whose visibility changes, without resizing.
Thx in advance.
EDIT: the 2 updaded images from the post appear so compressed that we cannot see the problem. :(
But the first column width is decreased of -30% causing the whole page layout to be broken.

Put your gridView inside a div tag and set its attributes i.e.
<div id="ScrollList" style="height: 500px; overflow: auto">
<!-- your gridview -->
</div>
And also set the width of your boundfields i.e.
ItemStyle-Width="100%" ControlStyle-Width="100%"
Hope it helps.

Gridview WebUserControl access selected row

i have a grid view in the web custom control and want to select any row and so that i can edit that row. the edit button is on the master page and default.aspx is inherited from that master and know i want the row id on my defult page so that i can edit that row easily.
my web user control is
<asp:GridView runat="server" ID="grvBranches" GridLines="None"
AutoGenerateColumns="False" CellPadding="5"
OnRowDataBound="grvBranches_RowDataBound"
OnRowCancelingEdit="grvBranches_RowCancelingEdit"
OnRowEditing="grvBranches_RowEditing"
OnRowUpdating="grvBranches_RowUpdating">
<SelectedRowStyle BackColor="#d8d8d8" />
<HeaderStyle BackColor="#d8d8d8" />
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:Label Text="BranchName" ID="lblHeaderBranchName" runat="server" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label Text='<%# Eval("ID") %>' ID="lblID" Visible="false" runat="server" />
<asp:Label Text='<%# Eval("Branch_Name") %>' ID="lblBranchName" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
<asp:Label Text="OrganizationName" ID="lblHeaderOrganizationName" runat="server" />

</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>

<asp:TemplateField>
<HeaderTemplate>
<asp:Label Text="City" ID="lblHeaderCityName" runat="server" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label Text='<%# Eval("City_Name") %>' ID="lblCityName" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField />
<asp:CommandField ShowSelectButton="True" />
</Columns>
</asp:GridView>
and i want this rowid in on my Default page

On your master page .cs, on the EditButton click event
GridView gView = ContentPlaceHolder1.FindControl("GridView1") as GridView;
// use gView.SelectedIndex to manipulate the row, edit it, etc
Assuming your main ContentPlaceHolder's ID is 'ContentPlaceHolder1'

GridView paging in UpdatePanel

I have an UpdatePanel and a GridView within it. I have a problem with paging: when I press Next button, grdUsers_PageIndexChanging() is not called, so the page stays 1, and if previously I changed selection in ddlPageSize, now it goes back to the initial selection.
Also, if I am on the first page, the Previous button is not disabled, and pressing it causes Out Of Range error.
What am I doing wrong?
Thanks.

Agreed, I tested the code, and grdUsers_PageIndexChanging() is called on mine.

Dear Friend
their is in build paging in the gridview if you want your own paging style then you have to implement your own paging through PageDataSource Class.
Click to view code
this link provide you how to implement the paging in the Datalist and Repeater through same way you will implement the paging in grid view .
Then no pageindex change event will fired in the gridview.

I don't think you are doing anything wrong; it may not actually fire the PageIndexChanged event, it probably fires the RowCommand event. Attach to the ItemCommand event and that will receive the event.
HTH.
