How do i insert a session variable into gridview

Hello,

I am using ASP.NET and VB.NET, I have a gridview wconnected to a table adapter which returns 3 columns from a database. Column 1 is a feature ID, column 2 is a description and column 3 is detail.

Can I in some way insert a Session variable into a cell in Column 3 where ID = 3 for example.

thanks, much appreciated.

Put one more if statement in, to check the row index (to see if the row match your condition then change it).This wont slow down the performance (very very little effect).

If e.Row.RowType = DataControlRowType.DataRow Then
      if e.Row.Cell(0).Text = "3" then    'or equals your wanted ID
         ' Get your session variable and display here.
         e.Row.Cells(2).Text = "<i>" & Session("MySessionValue") & "</i>"
      End if
 
    End If

Hope this help

Hi,

You can interfere anytime in anyway your gridview bind its data, and manipulate the way you want it.

Set the event RowDataBound of your gridview (this event will be fired when datarow is bounded, your can set how you want the specific cell to display. You use VB right? So please take a look at the example:

<asp:gridview id = "myGridView" runat = "server" onRowDataBound = "..." ... > (you better get this on your design)

Hope this helps

Sub CustomersGridView_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
 
    If e.Row.RowType = DataControlRowType.DataRow Then
 
      ' Get your session variable and display here.
      e.Row.Cells(2).Text = "<i>" & Session("MySessionValue") & "</i>"
 
    End If
 
  End Sub

thanks for the response,however, what this is doing is filling all the cells in the column with the same variable. I want just 1 specific cell.

thanks.

If you want to insert that value after the grid has been populated then you need to update the datatable which is the source of the grid. If you are using dataset or datatable to populate the grid, you could insert the value into table and then refresh the grid. For example

dTable.DefaultView.RowFilter="FeatureID=3"
if dTable.DefaultView.Count>0 then
   dTable.DefaultView.Item(0).Item(2)="SomeValue"
end if
dTable.DefaultView.RowFilter=""
dGrid.DataBind()
