.net DDL problem

[Stelly]

Hi there...

For some reason my DDL, which the code is:

protected void DropDownListSoft_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList DDL_Soft = (DropDownList)SoftList.FindControl("DropDownListSoft");

string No = DDL_Soft.SelectedItem.Value;

}

keeps throwing up the error "Object reference not set to an instance of an object." any ideas why??

at a guess it's this line:
(DropDownList)SoftList.FindControl("DropDownListSoft");

It can't find the DDL.

Yes I was thinking that but... I dont know why as I have used it in commands...

probably because it can't find the control, and returns a null object.

you should not have to use the Findcontrol method though, try and access your control directly instead.

Done it...

DropDownList DDL_Soft = (DropDownList)SoftList.FooterRow.FindControl("DropDownListSoft");

Just needed to concentrate and remember it was in the footer of the gridview

Stelly, there must be a better way of doing this. Is the sender parameter not the DDL you are looking for?

DropDownList DDL_Soft = (DropDownList)SoftList.FooterRow.FindControl("DropDownListSoft");

That works fine... need to get the value and insert it into an sqlstatement
