Very newbie question and I hope this is the right group. I have a
table on a web page which contains info about paint colors. One column
contains the hex value for the color's RGB value. I want to display
info from the table in a grid or table and use the column value from
the RGBHex column to set each row's back ground color. I can just
about do this in my sleep in old style ASP using <%%tags but I would
like to implement it in .NET 2. My website has this implemented in
old ASP here: www.paintmatcher.com/tool/tool.asp Any help is greatly
appreciated. 10  9813

it could be the same as in ASP 3:
bgcolor="#<%=he x_value%>"
where "hex_value" is a variable
Here's a snippet of the code created by MS Vis Web Developer 05
Express. The data from the table displays just fine. I want to set
the back color of each row based on the value of the "RGBHex" field.
<asp:GridView ID="GridView1" runat="server" AllowSorting="T rue"
AutoGenerateCol umns="False"
DataKeyNames="I D" DataSourceID="A ccessDataSource 2"
EmptyDataText=" There are no data records to
display.">
<Columns>
<asp:BoundFie ld DataField="ID" HeaderText="ID"
ReadOnly="True" SortExpression= "ID" />
<asp:BoundFie ld DataField="Bran d" HeaderText="Bra nd"
SortExpression= "Brand" />
<asp:BoundFie ld DataField="Colo rname"
HeaderText="Col orname" SortExpression= "Colorname" />
<asp:BoundFie ld DataField="RGBV alue" HeaderText="RGB Value"
SortExpression= "RGBValue" />
<asp:BoundFie ld DataField="RGBH ex" HeaderText="RGB Hex"
SortExpression= "RGBHex" />
</Columns>
</asp:GridView>
Could I use ASP 3 <%%tags inside the BoundField tag? How would I
call the field value using ASP.NET to assign to the variable? Or
maybe there's a better solution than using a GridView. Any other
ideas?
Thanks.

In this case you should rewrite a GridView_RowDat aBound event.
Change <asp:GridView ID="GridView1"
OnRowDataBound= "GridView1_RowD ataBound"....
and add the GridView1_RowDa taBound event to your code (code-behind)
C#:
protected void GridView1_RowDa taBound(object sender,
GridViewRowEven tArgs e)
{
if (e.Row.RowType == DataControlRowT ype.DataRow)
{
string c = e.Row.DataItem["RGBHex"]; // e.g. "#000000"
e.Row.BackColor = System.Drawing. ColorTranslator .FromHtml(c);
}
}
I didn't test it but it should work, I think

Mate, you have to start from the basic.
It told you that you miss a class, that is you have to define the
_Default
Remember, you said <%@ Page .... Inherits="_Defa ult"
<!--------------- This is the name of your class
So, the code-behind should be like this:
using System;
using System.Data;
using System.Configur ation;
using System.Collecti ons;
using System.Web;
using System.Web.Secu rity;
using System.Web.UI;
using System.Web.UI.W ebControls;
using System.Web.UI.W ebControls.WebP arts;
using System.Web.UI.H tmlControls;
public partial class _Default : System.Web.UI.P age
{
protected void Page_Load(objec t sender, EventArgs e)
{
}
............... ....code here........... ........
