                                </EditItemTemplate>

Error:

BC30456: 'confirmerSupprimer' not aa member of 'ASP.Facturation_aspx'.

What's the pb

Answer 1

This function is declared in JavaScript - your GridView is expecting a method declared in C# —that's why you're getting that error.

If you want to wire this image button up with that JavaScript function, you could add this call to the Attributes collection in your code behind.

<asp:DataGrid OnItemDataBound="yourDataGrid_RowDataBound" 

protected void yourDataGrid_RowDataBound(object sender, DataGridItemEventArgs e)
{
    if (e.Item.ItemType != ListItemType.AlternatingItem && e.Item.ItemType != ListItemType.Item) return;

    ImageButton ib = e.Item.Cells[YourIndex].FindControl("ibDelete") as ImageButton;
    ib.Attributes["onclick"] = "javascript:return confirmerSupprimer()";
}
