I want to create a GridView dynamic with a buttoncolumn in each row and do a Click at that ImageButton. This ImageButton have a commandargument filled in - and I whish to resspond to that commandargument When I click at the button and do something with this value.

I can easy run the method imgBtn_DataBind() - but not the others :-(

I can easy create the grid and add labels to it and create the ImageButton's too - but when I add some events to these buttons I can not get the debugger to stop in these routines :-(

So what do I do for accessing these methods and do something here? I really hope that there is an answer ;-)

Or do I need to consider a repeater?

Regards Michael

What I have tried:

I have the following code:
public class DynamicGridViewImageButtonTemplate : ITemplate
    string _ColNameText;
    DataControlRowType _rowType;

    public DynamicGridViewImageButtonTemplate(string ColNameText, DataControlRowType RowType)
        _ColNameText = ColNameText;
        _rowType = RowType;

    public void InstantiateIn(System.Web.UI.Control container)
        switch (_rowType)
            case DataControlRowType.Header:
                Literal lc = new Literal();
                lc.Text = "" + _ColNameText + "";
            case DataControlRowType.DataRow:
                ImageButton vImageButton = new ImageButton();
                vImageButton.ID = "btnGetVoucher";
                vImageButton.ImageUrl = "~/Images/Icons/icons8-download-from-the-cloud-50.png";
                vImageButton.PostBackUrl = "#DownloadVoucher";
                vImageButton.CommandArgument = string.Format("<%# Eval({0}) %>", "Voucher");
                vImageButton.ToolTip = "Se og download bilag";
                vImageButton.CssClass = "divButton";
                vImageButton.Height = 25;
                vImageButton.Width = 25;
                vImageButton.DataBinding += new EventHandler(this.imgBtn_DataBind);
                vImageButton.CommandName = "DownloadVoucher";
                vImageButton.Command += new CommandEventHandler(btnGetVoucher_Command);
                vImageButton.Click += new ImageClickEventHandler(btnGetVoucher_Click);

    private void imgBtn_DataBind(Object sender, EventArgs e)
        ImageButton btn = (ImageButton)sender;
        GridViewRow row = (GridViewRow)btn.NamingContainer;
        btn.CommandArgument = DataBinder.Eval(row.DataItem, _ColNameText).ToString();

    protected void btnGetVoucher_Click(object sender, ImageClickEventArgs e)


    protected void btnGetVoucher_Command(object sender, CommandEventArgs e)
        ImageButton btn = sender as ImageButton;

And I have tried to call the methods and them to the GridView in this way (vGridView is the GridView()):
vTemplateField = new TemplateField();
vTemplateField.HeaderTemplate = new DynamicGridViewImageButtonTemplate("Voucher", DataControlRowType.Header);
vTemplateField.ItemTemplate = new DynamicGridViewImageButtonTemplate("Voucher", DataControlRowType.DataRow);

Maybe you should have one button that uses the selected row data to do whatever instead of adding a button to every row that does the same thing.
