[Code]....
I would like to change DataField="From" to DataField="To" before I call the GridView.DataBind.Please let me know if this is possible and if so how can I do it.

View 5 RepliesI was hoping this is simple but i have problems.
Basically i was only able to set the string color with itemstyle-Forecolor.
But how do i set the background of a column and also set height,width.Ok height may not work because i have an itemtemplate with predefined height.
Can this be done in a simple boundfield or must i have all my datafields in itemtemplates?
What i do for one column:

In my webpage there are some dropdown controls bounded by object datasource with postback= true.
By default there is a value (CurrentDate) selected in one of the dropdown.
To display data there is a gridivew.
When the page is loaded by default gridview is populated with some data as per currentdate.
In same page there is an image to export data to Excel. By default I mark this image's visible= false.
Therefore if the data is populated then the image should be visible to everyone to download data to Excel, if not populated then it should remain hide.
For this purpose I used this code:
[Code]....
But exactly don't know where to write above code. If I write in Page_Load event then on runtime it displays error that:
Value cannot be null.
Parameter name: Statement_Date
In my asp.net+vb we+access DB. i have a field named DOB which is date of birth. i displays the data in grid view whose DOB+90 is less than ot equl to current date
DOB+90<=now()
and it works currect. but when i try to used vb code to change the row colour as per data it works for this one.
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
If (e.Row.DataItem("DOR") <= Now()) Then
e.Row.ForeColor = Drawing.Color.Red
End If
But i want three diffrent conditions
1. whose DOB=current month
2. whose DOB comes in next month
3. whose DOB comes in month after next month
The font colour should be diffrent
