How to change the Row selection color in RadgridView for Winforms

Hi,

I have my Radgridview for Winforms (vb.net) with multi-select option.

I have set my code to change the backcolor of the grid based on a criteria.

If CInt(e.RowElement.RowInfo.Cells("trd_typ").Value) = 0 Or CInt(e.RowElement.RowInfo.Cells("trd_typ").Value) = 20 Then
    e.RowElement.DrawFill = True
    e.RowElement.BackColor = Color.LightYellow
ElseIf CInt(e.RowElement.RowInfo.Cells("trd_typ").Value) = 3 Then
     e.RowElement.DrawFill = True
     e.RowElement.BackColor = Color.Gold
End If

It works perfect!

But now when I multi-select the rows it doen't show the color of the selection? Is there a way to have the rows selected to have different color? Atleast I need to differentiate the selected rows.

In the attachment I submitted, I have selected row 2,3 and 4. It just shows the border of the rows little darker. Its very harder to distinguish the color of the selection.

So I just want a color for selecting records and if I unselect it, the color should come back to the original color.

data dependent column visibility in gridview hierarchy

Hi,

I have a two level hierarchy in my RadGridview and want to hide a column on the second level grid, on a per row basis, based on a data element on the parent row.

I have attached an example, Based on the value of column3 of the master template, subColumn 4 is either visible or not.

I know how to programmatically set the visibility of the column, the only problem is that i do not have a per master template row granularity of control over the visibility of the second level grid's columns. the column is either visible for all of the second level hierarchy grids or not visible.

Is this a limitation of the gridview? At this point, some general guidance on this matter would be very helpful.

Thanks!

Threat a mouse Right-Button Click in the same way as a Left-Button Click?

Hi, my intention is to display a RadcontextMenu on a RadListControl when a mouse right-button is pressed or released (depending on the ClickMode configuration of the RadListControl).

I just would like to threat a right-button click in the same way as a left-button click is threated by default in a RadListControl, but I don't know whether Telerik provides a way to do this just by setting an specific property or somethins similar, what I'm doing is iterating the RadListControl items and determine which item contains the current mouse location but maybe this is a heavy method for big list item collections.

Pleasse. could you check my approach to see if it can be improved/simplified in some way via Telerik?

Also, I have an unsolved problem, in the line 96 of the code below I would like to determine which radListControl called the RadContextMenu to retrieve its SelectedItem.Text property, but I don't know if its possibly.

Thanks in advance.

Radgridview cell validating

Hi,
I have 2 columns among other columns in a radgridview: one is a textbox and the another is a button (Scan button). The user either can enter data in the textbox or can click on the scan button to get back data into the textbox. The textbox has some validation that I don't need to be triggered if the user is clicking on the Scan button but should be triggered if the user click on any other cell. How can do that as right now any validation is triggered as soon as I click on the Scan button.

Thanks,

GridView
