I want to grab a numeric value from the database and thereby use it in a datagrid. This will be connected to a linkbutton which has a hyperlink which will bring up profile information based on the number returned. I'm getting a value back but when I click the link, the querystring sees <% instead of the id number I want to use. So I'm really not sure what I'm missing so here's my code:

I want to change the text of a linkbutton by referring to it through a session variable.
For example how could a normal Linkbutton1.text = "buffoon" be referred to by a session variable if the Session("LinkButton") = "LinkButton1" ?

i want to store Session["Name"] into databse "name" column. how to do this ?

Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.
The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....
Object variable or With block variable not set.

I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:
*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)
*If Not localLblItemReference Is Nothing Then

To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.
In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:
Exception Details: System.NullReferenceException: Object variable or With block variable not set.

I have a title in the header for the column, but right below the title I'd like to have a linkbutton called "[Check All]". I know I could simply but the button above the grid and loop thru the grid, but I was wondering if it was possible to have a link button WITHIN the grid itself in the header section? If so, how can I go about coding this?

How do I add a LinkButton to a GridView pager? The only way I can think of implementing this is to dynamically add the numeric pages in the code behind and add the LinkButton I require in the PagerTemplate. owever in the example illustrated when a user clicks a numeric Page number the numbers disappear and nothing fires.
