There are a lot of things to explain in answer your question, so instead I'd recommend a good tutorial - try this - https://quickstarts.asp.net/quickstartv20/aspnet/doc/ctrlref/data/gridview.aspx

You can add a button in footer template like this example:
<asp:gridview ID="Gridview1" runat="server" ShowFooter="true" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
<asp:TemplateField HeaderText="Header 1">
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Header 2">
<ItemTemplate>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Header 3">
<ItemTemplate>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
</ItemTemplate>
<FooterStyle HorizontalAlign="Right" />
<FooterTemplate>
<asp:Button ID="ButtonAdd" runat="server" Text="Add New Row" />
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:gridview>

I don't want my OnRowCommand to execute for the first column of my GridView. Actually I don't want my event to fire when some of my checkboxes is clicked. How to determine if I have clicked on a checkbox or I have clicked somewhere else in a gridview? In WPF I could use e.OriginalSource property but here this is not possible.

Using JQuery:
If you haven't already added JQuery to your page, add this tag to your page's head section:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
And this is the actual code. Add this after the link to JQuery, in the .aspx page's head section:
<script type="text/javascript">
$(function(){
$('#<%= GridView_Messages.ClientID %> input[type="checkbox"]')
.click(function(event){
event.stopPropagation();
event.preventDefault();
})
});
</script>

Nested Gridview Footer Textbox Required Field Validation Firing for Each Row on Nested Gridview Footer Button Click

I am trying to get the required field validation to fire only for the specific row when the add button is clicked. But right now, when I click any add button, it fires the required field validation for all nested grid rows. The code for the nested gridview and the image of the gridviews is the following. I also tried to use validation groups, attempting to get unique validation groups for each nested gridview row, but couldn't get it to work.

For the validation control of each row you are adding the ValidationGroup='<%# "PC" + Eval("ContractProjectCodeID") %>'. As you are saying, that the validation triggers for the wrong row, it could be that ContractProjectCodeID may not be unique for each row. I think what you can do is add row index to the validation group
ValidationGroup='<%# "PC" + Container.DataItemIndex + Eval("ContractProjectCodeID")

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:

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 "**

gridview sort order changes when editing row

i have a gridview which simply displays records based on a filter from a dropdownlist, when i change the dropdownlist the page postbacks fine and the filter works, but when i click to edit a row the sort order changes based on the new filter. when i change the drop down back to the original filter and click edit the sort order remains the same.
any ideas?
