[Solved] Reset cell format

I have a GridView where I am changing the cell BackColor when the value is changed:

void TelerikGridView_CellValueChanged(object sender, GridViewCellEventArgs e)

{

if (e.Row.Tag == null)

e.Row.Tag = e.Column.Name;

if (!e.Row.Tag.ToString().Contains(e.Column.Name))

e.Row.Tag += e.Column.Name;

}

void TelerikGridView_CellFormatting(object sender, CellFormattingEventArgs e)

{

if (e.Row.Tag != null && e.Row.Tag.ToString().Contains(e.Column.Name))

{

e.CellElement.DrawFill = true;

e.CellElement.GradientStyle = Telerik.WinControls.GradientStyles.Solid;

e.CellElement.BackColor = Color.Red;

}

else

{

e.CellElement.ResetValue(LightVisualElement.BackColorProperty, Telerik.WinControls.ValueResetFlags.Local);

e.CellElement.ResetValue(LightVisualElement.GradientStyleProperty, Telerik.WinControls.ValueResetFlags.Local);

e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, Telerik.WinControls.ValueResetFlags.Local);

}

This is working as expected, now I want to add a "Reset" button, when I click on it I would like to reset or remove the format of all the cells that have been changed, how can I accomplish this?

Regards,

Alberto

[Solved] RadPropertyChanged event of columns not fired after loading grid layout

I have a RadGridView which Layout should be saved whenever a column is added or removed by the user via columnChooser.

I added this code in Form.OnLoad:

foreach (GridViewDataColumn column in myGrid.Columns)

{

column.RadPropertyChanged += GridViewColumn_RadPropertyChanged;

}

And here is GridViewColumn_RadPropertyChanged event:

if (e.Property.Name == "IsVisible")

{

myGrid.SaveLayout(myPath);

}

This works fine - as long as I do not load an existing GridLayout. When I check in Form.OnLoad if there is an saved layout file and load that layout file for my Grid, the RadPropertyChanged event will not be fired anymore. Is there something additional I have to do with RadGridView after a layout has been loaded successfully?
