Change GridView row values using RowUpdating event

Nice Code :). The concept is neatly explained.
Fantastic code, really helped me with a DDL in a gridview issue. One question though.
I have 4 DDL's in a gridview. The first one is updating (mostly thanks to your code) but I can't get the other three to update. I'm a fairly new to C# and have never used the DictionaryEntry before. I naively tried just adding more if's (one for each ddl) within the foreach loop but that didn't work. Any help would be greatly appreciated.
Hi NobleMule, I'd written a new post for your question. Hope it'll be be solving your problem. Please let me know, whether it's solved or not.

Thanks so much for the reply and follow-up post. Unfortunately, it hasn't solved my problem. My code is as follows:
protected void NewRecordsGridview_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
foreach (DictionaryEntry entry in e.NewValues)
{
DropDownList ddl;
if (entry.Key.ToString() == "Direction")
{
ddl = (DropDownList)NewRecordsGridview.Rows[e.RowIndex].Cells[7].FindControl("DirectionGVDDL");
e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);
}
if (entry.Key.ToString() == "Outcome")
{
ddl = (DropDownList)NewRecordsGridview.Rows[e.RowIndex].Cells[6].FindControl("OutcomeGVDDL");
e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);
}
if (entry.Key.ToString() == "NextRunMonth")
{
ddl = (DropDownList)NewRecordsGridview.Rows[e.RowIndex].Cells[8].FindControl("NRMGVDDL");
e.NewValues[entry.Key] = Server.HtmlEncode(ddl.SelectedItem.Text);
}
}
}
The GridView I'm using has over 10 columns. However the foreach loop only cycles 5 times. On the third cycle, the first if statement is triggered but only the first one.
Once again, many many thanks for the follow-up post. I didn't expect a response so soon, let alone a response so thorough.
Hi,
I didnt find anything wrong with your code.
>However the foreach loop only cycles 5 times.

> triggered but only the first one.
This portion is not clear to me.
I suggest you to
(a) debug the code, by inserting Breakpoint (F9). That gives you a better control over your code.
(b) Cross-check the column names of the table used to compare with entry.Key.Tostring() (in your code).
Hope this helps.
Thanks.
