<asp:ButtonField  ButtonType="Button" CommandName="Edit" Text="Edit" Visible="True" CommandArgument='<%# Container.DataItemIndex %>' />


    </Columns>
</asp:GridView>
<asp:AccessDataSource ID="challanstatus" runat="server" 
    DataFile="~/App_Data/Database.mdb" 
    SelectCommand="SELECT * FROM [tblchallan] WHERE (([RegisNo] = ?) AND ([RegisNo] = ?))">
    <SelectParameters>
        <asp:ControlParameter ControlID="DropDownList1" Name="RegisNo" 
            PropertyName="SelectedValue" Type="String" />
        <asp:ControlParameter ControlID="DropDownList1" Name="RegisNo2" 
            PropertyName="SelectedValue" Type="String" />
    </SelectParameters>
</asp:AccessDataSource>

where i use

<asp:ButtonField  ButtonType="Button" CommandName="Edit" Text="Edit" Visible="True" CommandArgument='<%# Container.DataItemIndex %>' />

to insert button but it gives following error:

Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.ButtonField does not have a DataBinding event.

Answer 1

Ans :- to get value from row in variable

Bind button as like this

<asp:TemplateField>
 <ItemTemplate>
  <asp:Button runat="server" CommandName="Edit" Text="Pay Now" CommandArgument='<%# Eval("Amount")%>' />
 </ItemTemplate>
</asp:TemplateField>

Get value of this row on OnRowCommand event like this :-

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
 if (e.CommandName == "Edit")
 {
  decimal amount = Convert.ToDecimal(e.CommandArgument);
 }
}

hope this helps you to get value..
