Is there any way to solve this? I have looked through a lot internet source but still not able to do it. Please help me..
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" AllowSorting="True" BorderStyle="Solid" Font-Names="Tahoma" Font-Size="11pt" HorizontalAlign="Center" Width="65%">
<Columns>

Any help is highly appreciated ...Thanks in advance...

First: if you go to MSDN concerning UpdatePanels and scroll down to the section:
Controls that Are Not Compatible with UpdatePanel Controls
You find this:
GridView and DetailsView controls when their EnableSortingAndPagingCallbacks property is set to true.
Paging a Gridview requires a Postback. Typically when you use any kind of modal/popup control it uses JS to activate. But a postback is going eliminate the popup...so...
The main thing is you need to be able to maintain the popup state between postbacks. There are a couple of ways to handle this.
Easiest is to eliminate the paging and use scrolling, assuming the total number of items is a manageable list. If the list is too long chances are that it's also too much information for a user anyway and should be filtered to a manageable list.
If you must use paging, you need to use a popup control that can withstand postbacks, which may mean using an <iframe>. I don't know enough about the AjaxControlToolkit to say if it can be done that way.
Personally, when I needed to do what you are trying to do via popup, I use Colorbox. But this also requires jquery.
I move the gridview to a standalone page and configure Colorbox to open the page in an iframe. This way the iframe manages the paging postbacks.

ASP .NET GridView not showing sorting arrows

I have the following Gridview. I need sorting arrows in every column header for sorting. I have set AllowSorting property to true.But it is not showing the arrows.Additionally, I added SortExpression to template fields .Still it is not showing the sorting arrows. I couldn't understand the issue. How can I fix this issue?
The code is given below
<asp:GridView ID="dgvCatReport" runat="server"
AutoGenerateColumns="False" CellPadding="4"
ForeColor="#333333" GridLines="None"
AllowPaging="True"
AllowSorting="true"
OnPageIndexChanging="dgvCatReport_PageIndexChanging"
PagerSettings-Mode="NumericFirstLast"
PagerSettings-Position="TopAndBottom"
PageSize="10"
CssClass=" table table-striped table-hover"
AlternatingRowStyle-CssClass="alt"
PagerStyle-CssClass="bs-pagination">
<columns>
<asp:templatefield headertext="Category Name" sortexpression="CatName">
<itemtemplate>
<h5><%# Eval("CatName") %></h5>
</itemtemplate>
<headerstyle horizontalalign="Left" />
<itemstyle width="200px" />
</asp:templatefield>
<asp:templatefield headertext="Total Views" sortexpression="ReportCount">
<itemtemplate>
<span><%# Eval("ReportCount") %></span>
</itemtemplate>
<headerstyle horizontalalign="Left" />
<itemstyle width="75px" />
</asp:templatefield>
<asp:templatefield headertext="Daily Views" sortexpression="DailyCount">
<itemtemplate>
<span><%# Eval("DailyCount") %></span>
</itemtemplate>
<headerstyle horizontalalign="Left" />
<itemstyle width="75px" />
</asp:templatefield>
<asp:templatefield headertext="Weekly Views" sortexpression="WeeklyCount">
<itemtemplate>
<span><%# Eval("WeeklyCount") %></span>
</itemtemplate>
<headerstyle horizontalalign="Left" />
<itemstyle width="75px" />
</asp:templatefield>
<asp:templatefield headertext="Monthly Views" sortexpression="MonthlyCount">
<itemtemplate>
<span><%# Eval("MonthlyCount") %></span>
</itemtemplate>
<headerstyle horizontalalign="Left" />
<itemstyle width="75px" />
</asp:templatefield>
</columns>
<%-- <pagersettings mode="NumericFirstLast" position="TopAndBottom"></pagersettings>
<pagerstyle backcolor="White" cssclass="pgr"></pagerstyle>--%>
</asp:GridView>

I'm not sure if Asp.net grid provides default images for sorting. But you can still use a custom approach to show images.
set the Gridview properties
SortedAscendingHeaderStyle-CssClass="sortasc"
SortedDescendingHeaderStyle-CssClass="sortdesc"
Add css classes:
th.sortasc a
{
display:block; padding:0 4px 0 15px;
background:url("images/icons/ascArrow.png") no-repeat;
}
th.sortdesc a
{
display:block; padding:0 4px 0 15px;
background:url("images/icons/descArrow.png") no-repeat;
}

How to set the width of TemplateField column in Grid view?

Hi I am developing a website using c# and asp.net. But my grid view is not showing properly for one page only. Whether I am using the same css class but still the output is something odd.
Here is the output I am getting:
here is my design view code for the grid:
<div style="width: 800px; align-content: center;">
<asp:GridView ID="gvMv" runat="server" AutoGenerateColumns="False" width="400px"
OnRowDataBound="gvMv_RowDataBound" CssClass="Grid" ShowFooter="True">
<FooterStyle Height="25" />
<RowStyle />
<PagerStyle />
<HeaderStyle />
<Columns>
<asp:BoundField DataField="day" HeaderText="Day" HeaderStyle-Width="150" ItemStyle-Height="25" HeaderStyle-Height="30">
<HeaderStyle Height="30px" Width="150px"></HeaderStyle>
<ItemStyle Height="25px"></ItemStyle>
</asp:BoundField>
<asp:TemplateField HeaderText="0.30"></asp:TemplateField>
<asp:TemplateField HeaderText="1.00"></asp:TemplateField>
<asp:TemplateField HeaderText="2.00"></asp:TemplateField>
<asp:TemplateField HeaderText="2.50"></asp:TemplateField>
<asp:TemplateField HeaderText="4.00"></asp:TemplateField>
<asp:TemplateField HeaderText="5.00"></asp:TemplateField>
<asp:TemplateField HeaderText="1.50"></asp:TemplateField>
<asp:TemplateField HeaderText="Total" ItemStyle-ForeColor="#0099FF">
<ItemStyle ForeColor="#0099FF"></ItemStyle>
</asp:TemplateField>
</Columns>
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" Font-Size="Smaller" />
<RowStyle CssClass="rSty" BackColor="#F7F7DE" />
<SelectedRowStyle BackColor="#CE5D5A" Font-Bold="true" ForeColor="White" />
<PagerStyle BackColor="#F7F7DE" ForeColor="Black" HorizontalAlign="Right" />
<HeaderStyle CssClass="hSty" BackColor="#6B696B" Font-Bold="True" ForeColor="White" />
<AlternatingRowStyle BackColor="White" />
</asp:GridView>
</div>
I want all of the column to be same width. Can anyone please help me on this?
Thank you.

I had the same issue and this is what worked for me
<asp:TemplateField ItemStyle-Width="150px" HeaderText="ABC" ItemStyle-HorizontalAlign="center">
<ItemTemplate>
<asp:Label ID="ABC" runat="server" Text ='<%# Eval("ABC")%>' ></asp:Label>
</ItemTemplate>
<HeaderTemplate>
<asp:TextBox ID="txtBusinessGroup" runat="server" onkeyup="filter_BusinessGroup(this)" CssClass="texbox_header" Width="130px" placeholder="ABC" Text="" ToolTip="TYPE IN THE ABC PLEASE"></asp:TextBox>
</HeaderTemplate>
<ItemStyle HorizontalAlign="Center" Width="150px" />
</asp:TemplateField>
I am showing textfield in the headertext which you can remove.
The width of the fields i change from
<ItemStyle HorizontalAlign="Center" Width="150px" />
or the actual textbox im using or the templatefield
<asp:TemplateField ItemStyle-Width="150px" HeaderText="ABC" ItemStyle-HorizontalAlign="center">
I hope this helps you and works for you or anyone else who might end up here.
thank you

Here is an example how you can do it :
<asp:TemplateField HeaderText="used">
<HeaderStyle Width="100" />
<ItemStyle Width="100" />
</asp:TemplateField>
You can use ItemStyle to set properties for your template field column

Try using this template code:
<asp:TemplateField HeaderText="ABC">
<ItemTemplate>
<asp:Label ID="lblABC" runat="server"
Text='<%#DataBinder.Eval(Container.DataItem, "ABCId") %>'>
</asp:Label>
</ItemTemplate>
<ItemStyle Width="20px" />
<HeaderStyle Width="20px" />
<FooterStyle Width="20px" />
<EditItemTemplate>
<asp:Label ID="lblEditABC" runat="server"
Text='<%#DataBinder.Eval(Container.DataItem, "ABCId") %>'>
</asp:Label>
</EditItemTemplate>
</asp:TemplateField>

i experienced the same. ItemStyle is not working! use HeaderStyle.
GridView1.Columns[2].HeaderStyle.Width = 20;

``If these all above code will note work to increase the width of gridview header then you can try this one also it will work definitely.Simply after YourText putt HTML space tag that is that much how much space you want.
**HeaderText="YourText "**

You need to use the RowDataBound event, access the controls for the row in the GridView and then set the values:

Also make sure no exceptions are being thrown!
