Confirmation box when deleting
-
when the delete button is pressed in my gridview i need a confirmation box to ask the user if they want to delete the row.
How?
-
-
just write in OnClientClick="return confirm('Are you sure to delete?';)" on your delete button.
-
that dosnt work mate all i get is 'OnClientClick dosnt exist in the current context'
+
i cant use that in the gridview
i am using ASP.Net and C# if that helps
-
I think what sainyam was trying to say is that you need a little piece of javascript added to the delete button ("return confirm('Are you sure to delete?';)")
Usually, this is added to the pages html section with a user event like "onClick". However, you can add it through the RegisterClientScript method in code if you prefer.

hi thedrunkendevilx,
can u plz post the desing code of your datagrid.....
-
Then the earlier post was correct (with a slight spelling mistake):
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="ButtonDelete" runat="server" Text="Delete" OnClientClick="BLOCKED SCRIPTreturn confirm('Are you sure to delete?');" />
</ItemTemplate>
</asp:TemplateField>I've basically included a button in a template column in the grid and assigned the earlier javascript to it... works fine.

"BLOCKED SCRIPT" = javascript with colon

Thanks joe90......that's what i was trying to explain
-
that is what i am trying to do its just that i have a command field not a template field
-
I figured as much sainyam... javascript can be a real pain with case and 'exactness' - very unforgiving IMHO.
At least 2008 has a javascript debugger in it - which should help many people out.

ya thats right...
-

Take a look here:

Though you may find this easier to follow:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
IButtonControl btn = e.Row.Cells[5].Controls[0] as IButtonControl;
((WebControl)btn).Attributes.Add("onClick", "return confirm('Are you sure you want to delete?');");
}
}
(you'll need to change the "5" to whatever column your button is in)Joe

i now have the message box poping up but it does nothing when i click ok. C# here is the code if it helps.
protected void dgvTimesheets_RowDataBound(object sender, GridViewRowEventArgs e){
if (e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer){
if ((e.Row.Cells[7].Controls[0] as CheckBox).Checked){
e.Row.Cells
.Visible = false;e.Row.Cells[9].Visible = true;
}
else{
e.Row.Cells.Visible = true;e.Row.Cells[9].Visible = false;
}
}
if (e.Row.RowType != DataControlRowType.Header && e.Row.RowType != DataControlRowType.Footer){
(e.Row.Cells[0].Controls[0] as ImageButton).Attributes.Add("onclick", "return ConfirmDelete();");}
}
-
Have you coded anything into the Command event?
Joe
-
i done it now all i need to know is how to stop the message from coming up twice because there is a bug with .net that fires the rowdeleting event 2 times.
thanks for all your help
Sam
