Hi
I have gridview with a values in as well as a dropdownlist
When I click on the dropdownlist to choose a value I need this value to then be updated to the database.
My question is how can I find the id of the current row I am on so that the correct record is updated?
any help on this would be great thanks!

Do you want to update all gridview data on button click event?
or
Do you want to update only one row on Droddown selected index change event?

I just need to update the row that I am currently on.
I want to update just the value I have chosen from the dropdownlist but I need to match it to the correct ID for that row. hope that makes sense
Also how can I find the dropdownlist for the current row.
I have:

DropDownList dd = ((DropDownList)row2.FindControl("ddorder")); but its showing object reference error
That code above is on my selectecchange event for the dropdownlist

thanks so far!!! Smile | :)

If you want to update single row on dopdown selected index change event then first find out dropdownlist on rowCreatedEvent of gridview and create event handler of selected index changed.

Look at here
On rowCreatedEvent of Gridview

if(e.Row.Rowtype==DataControlRowType.DataRow)
{
   DropDownList ddl=(DropDownList)e.Row.FindControl("DropDownListID")
   ddl.ToolTip=CurrentID; 
   //Get CurrentID of currentROw and set DropDownList ToolTip
   //Now create event Handler of DropDownList
}

On SelectedIndexChangeEvent,You have two argument e as eventArgs and Sender as an object
cast object to dropdownlist and get selectedValue and update data

for Example

DropDownList ddl=(DropDownList)sender;
string selectedValue=ddl.SelectedValue; //or ddl.SelectedText
string ID=ddl.ToolTip; //get ID and you can update your database value using this ID

Sorry it is RowType not Rowtype.
c# is case sensitive

if(e.Row.RowType==DataControlRowType.DataRow)

If you want to know the current GridViewRow:

DropDownList dd = ((DropDownList)row2.FindControl("ddorder"));
GridViewRow row = (GridViewRow)dd.NamingContainer;

Then you have the complete Row with values from the gridview in your OnSelectedIndexChanged for the DropDownList
