GridView Column modification - html

Question

I have bound my gridView with code behind which Contains 4 column but I want first column to be a linkbutton.
So I have added itemtemplate but now my grid contain 5 columns with two same columns, but I want only one column which is of linkbutton column.
This is my itemtemplate code
<Columns>
<asp:TemplateField HeaderText="File No">
<ItemTemplate >
<asp:LinkButton ID="LinkButton1" runat="server"
CommandArgument='<%# Eval("File") %>' Text='<%# Eval("File") %>'
OnCommand="show" ></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
Code behind grid binding :
Bussiness_logic.GridView_Bind(GridView1, "GET_DATA");
public static void GridView_Bind(GridView Grid_Name,String Procdure_name)
{
SqlDataAdapter dap = new SqlDataAdapter(Procdure_name, GetConnection());
DataSet ds = new DataSet();
dap.Fill(ds);
Grid_Name.DataSource = ds;
Grid_Name.DataBind();
}

Answer 1

Your Getting five columns because you Set GridView AutoGenerateColumn to trueAND add an extra template column in grid view.So GridView generate columns for all columns that are present in your data set and add you extra column i.e your template column.
Now to solve this issue Set AutoGenerateColoumn Property of GridView To false. Define Your Column Like below..
<Columns>
<asp:TemplateField HeaderText="File No">
<ItemTemplate >
<asp:LinkButton ID="LinkButton1" runat="server" CommandArgument='<%# Eval("File") %>' Text='<%# Eval("File") %>' OnCommand="show" ></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="NameofSecondColumnInYourDateSet" HeaderText="Column2"/>
<asp:BoundField DataField="NameofThirdColumnInYourDateSet" HeaderText="Column3"/>
<asp:BoundField DataField="NameofFourthColumnInYourDateSet" HeaderText="Column4"/>
</Columns>
