Question

I have a gridview and when a user selects a row I want to change the view in my multiview and display several new gridviews. A user would be clicking on a computer, and then it will display the computer stats/atached devices/etc. The new gridviews are going to need a column from the row that was selected, how do I get that? Thanks.

Answer 1

What language are you doing this on? I have done this in VB and C#.

1. Create an actionlistener for the first gridview (FocusedRowChanged) so when the user selects the row in the first gridview it will be called letting you know that the selected a different row
2. Within that listener you can find
   out which row was clicked on by
   using the arguments that it was sent
   (e) : e.FocusedRowHandle and then
   call a fetch on the second table.

3. Next create another actionlistener
   on the dataset that fills the second
   gridview.
   (secondDataset_BeforeFetch). Within
   this fetch you grab the column you
   need from the selected row in the
   first column

   DataRow row = FirstGridView.GetFocusedDataRow();

   row2.ItemArray[indexOfWantedColumn];

4. Finally within that actionlistener add the value you got in step 3 to the SqlCommand to send it with the fetch to fill the second gridview

   cmd.Parameters.AddWithValue(“@parameterName”, “valueToAdd”);

   Where valueToAdd is the value you got from the DataRow in the 3rd step.
