Changing the color of select datagrid rows 2

[Billkamm]

Is there a way to change the color of a datagrid row if a certain condition is met other than placing a helper function in every column?

use the ItemDataBound event of the grid. then you can check your conditon and change the color accordingly.

      If <somecondition> Then
            e.Item.BackColor = System.Drawing.Color.Blue
        End If

You can add code such as this on the OnDataBindEvent:

Sub dgChemData_ItemDataBound(sender As Object, e As System.Web.UI.WebControls.DataGridItemEventArgs)
If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then 
Dim strDO as String
strDO = DataBinder.Eval(e.Item.DataItem, "Oxygen")      
If strDO < 5 then ' oxygen..
 e.Item.Cells(4).Backcolor = System.Drawing.Color.Red
 e.Item.Cells(4).ForeColor = System.Drawing.Color.White  
End If

Although the principle is the same, I'd recommend changing the CssClass (e.Item.CssClass) rather than the BackColor otherwise these values will be hard coded and not particularly easy to change if you decide to visually update your site.

Excellent suggest ca8msm - in which case you can use the CSS file across many Grids and can be big timesaver. Billkamm you may take ca8msm up on his suggestion. Would you like a bit of code to show you how this would work? Let us know.

Thanks for the offer Isadore. I'm familiar with CSS already though.
