Dynamically changing grid row color at runtime

[Randy]

Hi,

I have a RadGridView that is using the AlternateRowBackground property to display different colors for every other row (basically odd and even rows).  I also have two RadColorPicker controls on the page that allows the user to be able to select the color they want to use for the odd row and the even row.  When the user selects a color, I want to be able to change the color of the row based on the user's selection. 

The documention seems to indicate that the AlternateRowBackground properly can be set and the color will change, but when I do that in the RadColorPicker event handler, nothing changes on the grid.

Is there a way to change the row colors dynamically based on a user selected value? 

Thanks for your time.
Randy

Hi Randy,

 Unfortunately there seems to be a bug causing the grid not refresh its alternate background properly. Calling Rebind() after you set the color is a possible workaround until we provide a fix for this.

Hi Kalin,

Thanks for the response - using Rebind() as the workaround does the trick for the alternate background property.

Is there a similar method for setting the background row color for the non-alternate rows?  Or is the only solution to use the RowStyle property?

Thanks,
Randy

Hello Randy,

For the normal rows you can use RowStyle or RowStyleSelector only.

Thanks Vlad - that is what I thought but wanted to confirm.

Hi Randy,

Can you provide some help on how you changed the colors of the rows in your grid View. I'm trying to do something similar to what you've done.

Thanks,
Kamil

Hi Kamil,

Try something like this:

// alternate row background color
YourGridView.AlternateRowBackground = new SolidColorBrush(Colors.Blue);

// standard row background color
var newRowColor = new Style { TargetType = typeof(Telerik.Windows.Controls.GridView.GridViewRow) };
newRowColor.Setters.Add(new Setter(BackgroundProperty, Colors.Green));
YourGridView.RowStyle = newRowColor;

// not sure if this line is still needed - the original bug may fixed
YourGridView.Rebind();

Hopefully this is what you were looking for.

Hi Rick Mueller,

You may test the functionality in our demos. Once you change the value of a UnitPrice to be less than 30$, the style will be updated.
