I have a gridview control that is bind to a value from database,inside the column tag I included an itemtemplate and within it an asp button control with the text property(Text ='<%#eval("somecolumnname") %>'). on the onclick attribute I want it to call another sub procedure(in my case its f) with some parameter. these parameter values should be the id of that particular row being selected.
How should I do that? below is the code:

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="act_id"
            DataSourceID="SqlDataSource1">
            <Columns>
                <asp:BoundField DataField="act_id" HeaderText="act_id" ReadOnly="True" SortExpression="act_id" />
                <asp:BoundField DataField="heading" HeaderText="heading" SortExpression="heading" />
                <asp:BoundField DataField="category_id" HeaderText="category_id" SortExpression="category_id" />
                <asp:TemplateField >
                <ItemTemplate >
                <asp:button runat ="server" ID="button" Text ='<%#eval("heading") %>' OnClick ="f" > </asp:button>
                </ItemTemplate>
                </asp:TemplateField>
              </Columns>
        </asp:GridView>

You can use OnROwCommand Event like this...

XML

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="act_id"
            DataSourceID="SqlDataSource1" OnRowCommand="GridView1_RowCommand">
            <Columns>
                <asp:BoundField DataField="act_id" HeaderText="act_id" ReadOnly="True" SortExpression="act_id" />
                <asp:BoundField DataField="heading" HeaderText="heading" SortExpression="heading" />
                <asp:BoundField DataField="category_id" HeaderText="category_id" SortExpression="category_id" />
                <asp:TemplateField >
                <ItemTemplate >
                <asp:button CommandName="myButton1" CommandArgument='<%# Eval("act_id") %>' runat ="server" ID="button" Text ='<%#eval("heading") %>' OnClick ="f" > </asp:button>
                </ItemTemplate>
                </asp:TemplateField>
              </Columns>
        </asp:GridView>

In the code behind..

C#

protected void GridView1_RowCommand(object sender,  GridViewCommandEventArgs e)
{
    int act_id = Convert.ToInt32(e.CommandArgument);
    if (e.CommandName == "myButton1")
    {
         string textOnTheButton=Convert.ToString(e.CommandSource);
         //your code here
    }
}

Hope this helps
