Here is a quick and easy reusable "ConfirmButtonField" for use on an ASP.NET GridView
Just simply derive from ButtonField and override a couple things:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace CreateSoftwareUtils.Web.GridViewControls
{
public class ConfirmButtonField : ButtonField
{
public override void InitializeCell(DataControlFieldCell cell, DataControlCellType cellType, DataControlRowState rowState, int rowIndex)
{
base.InitializeCell(cell, cellType, rowState, rowIndex);
if(cellType == DataControlCellType.DataCell)
{
cell.Attributes.Add("onclick","return confirm(\"Are you sure?\");");
}
}
}
}
Then on the ASPX page you can do this:
<asp:GridViewID="gvEquipment"runat="server"AutoGenerateColumns="false"DataKeyNames="ProductId">
<Columns>
<cs:ConfirmButtonField ButtonType="Link"Text="Delete"CommandName="Delete"/>
<asp:ButtonField ButtonType="Link"Text="View/Edit"CommandName="Select"/>
<asp:BoundField DataField="Name"HeaderText="Title"HeaderStyle-Width="300px"ItemStyle-Width="300px"ItemStyle-Wrap="true"/>
<asp:BoundField DataField="PriceDaily"HeaderText="Daily Rate"DataFormatString="{0:c}"HeaderStyle-Width="80px"/>
</Columns>
</asp:GridView>
I also like to register controls I am going to use all over the site in the Web.Config like this:
<add tagPrefix="cs"namespace="CreateSoftwareUtils.Web.GridViewControls"assembly="CreateSoftwareUtils"/>

I don't see how this is implemented in a page.
I can't get it to work as a user control, and can't register a regular class as a user control.
Could you expand? Thanks.
OK, I figured that out: the .cs file had to be in App_Code, and only 'tagPrefix' and 'namespace' attributes should be used in web.config.
But the return value of the script is not passed to the page, so the delete cannot be cancelled.
