Hello all, I have a gridview being populated by a database. Just one column in gridview with a select link. I am trying to retrieve a value from the gridview when the user clicks on Select. I have tried GridView1.SelectedValue.Cells(0).Text and Gridview1.SelectedRow.Cells(1).Text in the code for button click and I am getting "Object variable or With block variable not set." and NullReferenceException Unhandled by user code. Any help would be greatly appreciated. This is not home work. I had ASP.NET and VB6 back in 2003.

This is what I have:
Dim query As String = "select Approved from tablename where [name] = '" & Session("name") & "' And Book= '" & GridView1.SelectedValue.Cells(0).Text & "'"

Can you provide code as to what the issues you are referencing refers to?

You will have to post more code than that. But I can tell you that the gridview.selectedvalue does not have an attribute of .Cells but gridview1.SelectedRow does. Try this:

Solution 1

GridView1.SelectedValue gives the datakey value of Selected Row not the actual row but  Gridview1.SelectedRow.Cells(1).Text should work,check whether any row is selected or not,for that check the selected index. 
Can try it too:
