I have 2 GridViews. One is working perfectly. What I would like to have happen is when a row is selected on GridView1 (with Primary key of OrderNumber), the matching records from the field in GridView1 ClientID to show up in GridView2.
[Code]....
I think I've narrowed my problem down to CilentID is not a primary key, but still there should be some way to link them.

but I cant get the value from these non-primary datakeynames...

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

I have a Gridview with ID "GVSeasonsOfResort" which has selectable rows.
One of the fields in that gridview is RSLinkID which is an ID field of the table from which ths SQLDataSource driving the gridview gets its data.
I have a textbox outside the gridview with ID TxtBxRSLinkID and when I select a row of the Gridview, I want to assign the value of the RSLinkID field of the selected row to the TxtBxRSLinkID.

[Code]....
and now as you can see i have a link Button and i have its handler. Before i used to have a Check box and i could find with row has been selected, but now my style is different , i want to get value of "lblOrderID" for the selected record. I dont use a Checkbox to get the selected item because i dont allow multi select into functionality.
How can i get that on the server or client side.

I have to GridViews, say grd1 and grd2.
grd1 is bound programmaticaly in Page_Load, it contains hyperlink column that loads the same page with ID value in request.
grd2 also is bound in Page_Load and it depands on ID from request (so, after grd1 is clicked grd2 loads data).So, actually grd2 depands on grd1.
After page is reloaded with id in request, I should know the row from grd1 where user has clicked and display some of column data seperatly (say in label lblColumnData). How to know which row was clicked?

I have a gridview that uses a dynamic dataview as the datasource. Only some of the items in the dataview are included in the columns of the grid.
Dataview: Name, Address, Phone Number
GridView: Name, Address
When a user selects a row, I want to access the datafield not shown on the grid. Here is how I chose to do it.
[Code]....
Everything works fine with every row I select. The problem comes when I add the following code:[Code]....
I get the error:
Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index
This error occurs at the first part of the code where it is referring to the selected index. How can the second part of the code cause an error in the first part of the code that was working perfectly?
