I have a C# app using the Infragistics ultragrid in a Winforms solution. I need to do the following and I am unsure how after trolling through these forums.
1) currently when the grid is show on my form (using data binding) there is a row highlighted. I would like to have nothing at all highlighted in the grid (or active) when the user first comes to it
2) I need to check the value in a column on a per row basis (before displaying the grid to the user). If that row contains a certain value, then I need to change the background color for that whole row.
2) I need to check the value in a column on a per row basis. If that row contains a certain value, then I need to effectively disable this row. I am not allowing user edits on any of the data so editing is not a concern. I don't want them to be able to select this row at all. So if they try it simply ignores them (maybe supply a messagebox or something at the time too).
Is there an easy way to do this? I am spinning my wheels here. Thanks!

In this event, take a look at the value of a particular cell in the row, and change the row's color. For instance, assuming the grid has a boolean "ShowAsRed" coulmn:
if ((bool) e.Row.GetCellValue("ShowAsRed") == true) e.Row.Appearance.BackColor = Color.Red;else e.Row.Appearance.BackColor = Color.Empty; // Resets to the "default" color
Likewise, take a look at a different cell, and disable or enable the row based on that value. For instance, assuming the same grid has a boolean "Enabled" column:
if ((bool) e.Row.GetCellValue("Enabled") == false) e.Row.Activation = Infragistics.Win.UltraWinGrid.Activation.AllowEdit;else e.Row.Activation = Infragistics.Win.UltraWinGrid.Activation.Disabled; // or use Activation.NoEdit or Activation.ActivateOnly if you don't want to use a "disabled" appearance
Hi,
in InitializeRow I have this code but the background color of the rows never change. I even forced the color without any condition and it still not changing.
private void ugdResult_InitializeRow(object sender , InitializeRowEventArgs e){ Color NewColor = decimal.Parse(e.Row.Cells["Psu_AMOUNT_PAID"].Value.ToString()) < 0 ? Color.Red : Color.FromArgb(0 , 0 , 0 , 0); e.Row.Appearance.BackColor = NewColor;}
Here it is. Thank you : http://es.infragistics.com/community/forums/p/108767/512151.aspx#512151
Hi Marc,
You might be better off starting a new thread. This one is from 2009 and doesn't really relate. So that might be why you didn't get any response.
Anyway, Assuming that line of code that sets the BackColor is getting executed, then something else must be overriding the row's appearance. This could be because you are using AppStylist or maybe you are setting other Appearances that cover the row - for example, the CellAppearance for the cells in that row or the RowCellAppearance on the row.
Any idea guys ?
