View 3 RepliesI need to loop through a gridview and get the values of some dropdownlist controls at that time.I am binding the gridview from a datatable I created.
Code:
gvFields.DataSource = myDataTable
gvFields.DataBind()
Now I am going through the rows of the gridview manually and need to get the values. You can see I have tried different ways. How can I do this from clicking a button to get the values instead of any other event? I only get True or False returned instead of the text in the dropdownlist controls.
Code:
For X = 0 To gvFields.Rows.Count - 1
Dim chkBox As CheckBox = CType(gvFields.Rows(X).Cells(0).Controls(1), CheckBox)
If chkBox.Checked = True Then
Dim ColumnName2 As String = Trim(gvFields.Rows(X).Cells(1).Text)

View 3 RepliesI've seen several examples here but for some reason I still cant get this to work. I have a gridview of user information.
userid name phone role
00001 john 12345 [downdownlist]
00002 jack 12345 [downdownlist]
00003 jeffz 12345 [downdownlist]
00004 jims 12345 [downdownlist]
The code would look something like this:
<asp:GridView
ID="gvUsers"
runat="server"
AutoGenerateColumns="False"
DataSourceID="dsUsers"
DataKeyNames="id"
[Code].....
So as my example code above shows, I'm trying to build a dropdownlist within the gridview. The datasource for the dropdownlist is based on the userid. The two datasources (dsUsers, dsRoles) are two different tables in the database. HOw can I implement the dropdownlist to use the userid from the gridview to query the dsRoles to populate its list?
