Hello Samuel,

Thank you for contacting Telerik Support.

In order to change the cell and row border for IsSelected, IsCurrent and HotTracking states, it is necessary to customize the theme by modifying the specific grid CellElement's and GridDataRowElement's repository items for the specific element states via our Visual Style Builder.

You can read more details about using the VisualStyleBuilder here:
1.     Loading predefined themes
2.     Working with Repository Items
3.     Saving and Loading Theme Files
4.     Loading Themes from an External File
5.     Loading Themes from a Resource
6.     Applying Theme to a Control
7.     http://tv.telerik.com/watch/winforms/visualstylebuilder/whats-new-visual-style-builder-q1-2010

You are allowed to set EnableHotTracking property to false in order to switch off the entire hot tracking indication.

I hope this information helps. Should you have further questions, I would be glad to help.

I need to prevent the Grid from turning all gray when I disable it. how can i do that?

Hello Kim,

Thank you for contacting Telerik Support.

When you set the GridViewElement.Enabled property to false, you should set the UseDefaultDisabledPaint property to false as well, in order to prevent the grid from coloring in gray:

public Form1()
{
    InitializeComponent();

    this.radGridView1.GridViewElement.Enabled = false;
    this.radGridView1.GridViewElement.UseDefaultDisabledPaint = false;
}

I hope this information helps. Should you have further questions, I would be glad to help.

Thanks for your reply, When I use;

this.radGridView1.GridViewElement.Enabled = false

the user can still select a different row, and the row highlight disappears.

What I want to be able to do is prevent the grid form receiving any user input, but not change its visual appearance.

Hello Kim,

Thank you for writing back.

In order to keep the normal visual representation of the RadGridView, but disabled its selection changing, sorting, grouping, editing functionalities, etc. it is necessary to stop them manually. One sample approach is introduced below:

public Form1()
{
    InitializeComponent();

    BaseGridBehavior gridBehavior = this.radGridView1.GridBehavior as BaseGridBehavior;
    gridBehavior.UnregisterBehavior(typeof(GridViewDataRowInfo));
    gridBehavior.UnregisterBehavior(typeof(GridViewNewRowInfo));
    gridBehavior.UnregisterBehavior(typeof(GridViewGroupRowInfo));
    gridBehavior.UnregisterBehavior(typeof(GridViewFilteringRowInfo));
    gridBehavior.UnregisterBehavior(typeof(GridViewTableHeaderRowInfo));
    gridBehavior.UnregisterBehavior(typeof(GridViewHierarchyRowInfo));
    gridBehavior.UnregisterBehavior(typeof(GridViewDetailsRowInfo));

    this.radGridView1.ReadOnly = true;
    this.radGridView1.EnableHotTracking = false;
    this.radGridView1.AllowRowResize = false;

    this.radGridView1.CurrentRowChanging += radGridView1_CurrentRowChanging;

}
private void radGridView1_CurrentRowChanging(object sender, CurrentRowChangingEventArgs e)
{
    e.Cancel = true;
}

Please do not hesitate to contact us if you have any additional questions.
