Hi...
I have the following problem:
I have a global variable
String TableColor = "";
and want to assign the value of TableColor to BackColor
<ASP:DataGrid id="MyDataGrid" runat="server"
Width="100%"
BackColor="<%=TableColor%>
BorderColor="black"
ShowFooter="false"
CellPadding="3"
CellSpacing="0"
Font-Name="Verdana"
Font-Size="8pt"
HeaderStyle-BackColor="#aaaadd"
/>
But I canīt get it right. Is it possible? Can someone please help me?
Best regards
Mikael

Mikael,
Yes, it is possible. What makes this difficult is that the BackColor
property of the datagrid expects a value of type System.Drawing.Color (as
opposed a value of type String which is what I think most people who are new
to the framework will try). Because of this, you can still use a string
value to represent the color you want but you will also have to pass the
string value into the FromName method of the System.Drawing.Color class. For
example (notice I set the BackColor property in the code as opposed to the
BackColor property in the datagrid declaration),
------------------- test.aspx -------------------------
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SQL" %>
<script language="C#" runat="server">
String TableColor = "blue";
void Page_Load(Object Src, EventArgs e)
{
DataSet myDataSet = new DataSet();
String SelectCommand ="Select * from Products";
SQLConnection MyConnection = new SQLConnection("Data
Source=localhost; uid=sa; pwd=; Initial Catalog=northwind");
SQLDataSetCommand MyCommand = new SQLDataSetCommand(SelectCommand,
MyConnection);
MyCommand.FillDataSet(myDataSet, "Products");
DataView myDataView = myDataSet.Tables["Products"].DefaultView;
MyDataGrid.BackColor = System.Drawing.Color.FromName(TableColor);
MyDataGrid.DataSource = myDataView;
MyDataGrid.DataBind();
}
</script>
<ASP:DataGrid id="MyDataGrid" runat="server"
Width="100%"
BorderColor="black"
ShowFooter="false"
CellPadding="3"
CellSpacing="0"
Font-Name="Verdana"
Font-Size="8pt"
HeaderStyle-BackColor="#aaaadd"
/>
----------------- end of test.aspx ------------------------------
hth,
Alex

It's not the answer to your question but try to don't use inline code with
ASP.net
In Page_Load event, write :
MydataGrid.Backcolor = CType(TableColor,Color)
or something like that
