I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.

The gridview control shows about 13 columns from the database. But we want the user to be able to edit only one column. Rest of the 12 columsn should be read only. When the clicks one Edit button button, as usual the Update and Cancel buttons should come up. It is not happening. Only the _Rowediting event is getting trigged. Following is the code from my .aspx page. I don't know anything about template columns and not sure if I have to use that concept in my situation.
How do I control the gridview's column width wherein my gridview is dynamically populated from a dataset. What I want to achieve is to have a somewhat uniform column width for all column entries. I have already tried specifying the Itemstyle-width = "desired column" width but still the content of the dataset still dictates the final width of the column. When I also try to set the ItemStyle-Warp = false, it does not still give me the desired effect because it will just increase the column width to fit the content of the dataset. I think to achieve my desired effect and since some contents of the dataset are long, the solution would be to truncate the dataset prior to binding it to the gridview but I don't know how.
like this in a function in AddColumns button clickevent
gv.Columns.Clear() Dim chkCol As New TemplateField chkCol.ItemStyle.Width = 20 chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center gv.Columns.Add(chkCol)

Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim chkbox As New CheckBox chkbox.ID = "chkSelect" e.Row.Cells(0).Controls.Add(chkbox) End If End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click Dim linkId As String Dim summary As String = "" 'Enumerate the GridViewRows For index As Integer = 0 To Me.gv.Rows.Count - 1 'Programmatically access the CheckBox from the TemplateField Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox) If cb IsNot Nothing Then If cb.Checked Then linkId = Me.gv.DataKeys(index).Value End If End If Next Me.Page.Title = linkId End Sub

I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).
