From: Eric on 18 Dec 2009 05:19 Hi, I have a gridview with the last column to be a buttonfield. This is a delete button. When the user clicks it, the RowCommand event will be fired and the rowcommand property holds the line number. I would like from the rowcommand event, to show a popup asking the user if he wants to continue, like a javascript confirm box. I can put up the box with ClientScript.RegisterStartupScript(Me.GetType(), "confirm", "<script>confirm('" + Msg + "');</script>") but how can I get it to go to link1 if the answer is ok? something like: ok pressed --> "~\default.aspx?userclickedOK=true" is this at all possible? rg, Eric

Yes, but you're making things unnecessarily complicated... <Columns> <%-- other columns --%> <asp:TemplateField HeaderText="" ItemStyle-Wrap="False"> <ItemTemplate> <asp:Button ID="cmdDelete" runat="server" Text="Del" OnCommand="cmdDelete_Command" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "ID").ToString()%>' OnClientClick="return confirm('Are you sure you want to delete this record?');" /> </ItemTemplate> </asp:TemplateField> </Columns> protected void cmdDelete_Command(object sender, CommandEventArgs e) { // ID to be deleted is e.CommandArgument.ToString() } No need for RowCommand or anything like that... -- Mark Rae ASP.NET MVP http://www.markrae.net

Here's an example on VB Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If (e.Row.RowType = DataControlRowType.DataRow) Then If (e.Row.RowState = DataControlRowState.Normal Or e.Row.RowState = DataControlRowState.Alternate) Then Dim l As LinkButton = e.Row.Cells(0).Controls(0) <---- this must be change acc. to your grid setup l.Attributes.Add("onclick", "javascript:return confirm ('Are you sure?')") <--- this is your confirm script End If End If End Sub If user pressed OK then RowDeleting Event get fired Protected Sub GridView1_RowDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewDeleteEventArgs) Handles GridView1.RowDeleting .... End Sub and this is where you can programmatically redirect to the new page. Hope this helps

When the user clicks on de delete button, the popup does appear. Clicking on cancel will just remove the popup, clicking on OK does a page refresh, but the RowDeleting event is not fired. How can I get it fired? here is my code about the creation of the column: Dim clBT As New ButtonField clBT.HeaderText = "" clBT.HeaderStyle.BackColor = gridbackcolor clBT.HeaderStyle.ForeColor = gridforecolor clBT.HeaderStyle.Font.Name = "Arial" clBT.HeaderStyle.Font.Bold = True clBT.HeaderStyle.Font.Size = fontsize clBT.Text = "delete" clBT.ItemStyle.Font.Size = 8 clBT.ItemStyle.Font.Name = "Arial" clBT.ItemStyle.Font.Underline = True clBT.ButtonType = ButtonType.Link clBT.ItemStyle.Width = 40 clBT.ItemStyle.HorizontalAlign = HorizontalAlign.Center ctrl.Columns.Add(clBT) where ctrl is the gridview. This is the 14th column. The following is in the RowDatabound event: If e.Row.RowType = DataControlRowType.DataRow Then If e.Row.RowState = DataControlRowState.Normal Or e.Row.RowState = DataControlRowState.Alternate Then Try If e.Row.Cells(14).Controls.Count > 0 Then Dim lb As LinkButton = e.Row.Cells(14).Controls(0) lb.Attributes.Add("onclick", "javascript:return confirm('Are you sure?')") End If Catch ex As Exception End Try End If End If What can I do now? rg, Eric

So can use that since I don't use it for anything else. Not sure if it is the right solution, though. rg. Eric |
