Thanks for the advice curt but this still does not help me. If i try to set
the value for my linkbutton in Item_DataBound or Item_Created I get a object
not set to an instance of an object. Here is my code... The linkbutton
resides in a template column. What is wierd is the ButtonColumn that I
created that has an edit linkbutton alternates color on the grid. Why are
the TemplateColumn and ButtonColumn objects acting differently.
Public Class UpdateITemplateCol
Implements ITemplate
Public Sub InstantiateIn(ByVal container As System.Web.UI.Control)
Implements System.Web.UI.ITemplate.InstantiateIn
Dim btn As New LinkButton
btn.Text = "Update"
btn.ID = "Update"
btn.CommandName = "Update"
btn.CausesValidation = True
container.Controls.Add(btn)
End Sub
End Class
Public Class BaseTemplate
Inherits System.Web.UI.Page
'''Item Databound DG Event''''
Private Sub dgBedInfo_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles
dgBedInfo.ItemDataBound
Dim LinkBtn As LinkButton = CType(e.Item.FindControl("Update"),
LinkButton)
LinkBtn.ForeColor = GetUpdateLinkColor()
End Sub
'''Item Created DG Event"""
Private Sub dgBedInfo_ItemCreated(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgBedInfo.ItemCreated
Dim LinkBtn As LinkButton = CType(e.Item.FindControl("Update"),
LinkButton)
LinkBtn.ForeColor = GetUpdateLinkColor()
End Sub
'''Alternating Color Sub'''
Private Function GetUpdateLinkColor() As System.Drawing.Color
'AlternatingColor is a session variable accessed through public property
If (AlternatingColor = "Blue") Then
AlternatingColor = "White"
Return System.Drawing.Color.Blue
Else
AlternatingColor = "Blue"
Return System.Drawing.Color.White
End If
End Function
End Class

that's fine...
use the .Forecolor = GetColor(); as a function in the Item_DataBound (or
similar event) (perhaps Item_Created)

That might work if I was defining my controls in the aspx. file but I have a
base template page class. I am defining all my controls in the code behind.

Ahh....
The Styles/Css are determining it's coloring. You may want to start with
adding a cssClass to that item, but in an alternating way. Perhaps use a <%=
%> to hold the cssClass where the value is a function that retrieves an
alternating value
myColor = blue
Sub GetColor() as String
if(myColor=blue) then
myColor=white
else
myColor=blue
end if
return myColor
End Sub
....untested but it should be enough to get you started...
