Trying to get started with tables...

[Jeff]

I've been attempting to find the answer, but don't know what to search for.
If someone could get me started, I can figure the rest out.

I'm using visual web 2005 with vb.

The following works to change the background color on a table called
"table1"

Table1.BackColor = Drawing.Color.Blue

I would like to programatically change the background color on a row (or
column or both) within that table.
Could someone point me in the right direction.

Thanks

Jeff

Hi Jeff,

I assume you're referring to <asp:Table(System.Web.UI.WebControls.Table).
Let me know if this is not the case.

You could easily use Table.Rows(index) to get a reference to individual row
(of type TableRow). From the TableRow reference, you can use
TableRow.Cells(index) to get a reference to individual cell (of type
TableCell). Both of them also have a property named BackColor which can let
you set their background color.

I've written following code snippet to demonstrate how to change a row or
column's background color:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
' Add some rows/columns to the table
For i As Integer = 1 To 10
Dim tr As New TableRow
For j As Integer = 1 To 10
Dim td As New TableCell
td.Text = i.ToString + "." + j.ToString()
tr.Cells.Add(td)
Next
table1.Rows.Add(tr)
Next
' change third row's background color
table1.Rows(2).BackColor = Drawing.Color.Blue

' change third column's background color
' since the table is row-oriented, we need to set the cell
row-by-row
For i As Integer = 0 To table1.Rows.Count - 1
table1.Rows(i).Cells(2).BackColor = Drawing.Color.Gray
Next
End Sub
Hope this helps.

Hi Jeff,

I assume you're referring to <asp:Table>
(System.Web.UI.WebControls.Table).
Let me know if this is not the case.

Yes, I am referring to the above and understand your code example. I'm still
new to this, however, and can't figure out one last (small) thing. If I'm
working with a .aspx file in the design view of visual web 2005 with the
code-behind file .aspx.vb and if I create a table using the graphical
interface of the .aspx file by going to the layout insert table menu, and
subsequently give it the ID of "table1," the code below does not work, as
it apparently does not refer to the table I just created with the graphic
interface.

table1.Rows(2).BackColor = Drawing.Color.Blue

if I first declare table1 in the following manner, it still doesn't work
(when placed above the code listed above), but it now does not indicate an
error - when the thing is run, however, nothing happens.

Dim table1 As New Table

I know that this is certainly basic, but I'm not sure I understand how to
properly link the table in the DUI's design view and the vb code in the
codebehind file so that it can be programmatically manipulated.

Can you explain further?

Jeff

Never mind. I figured it out. ...don't use the layout table from the menu,
use the table from the toolbox.

Thanks.
