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?

Hi Johannes,

Thank you for writing.

A possible reason for the event not being fired is if you are not subscribing to it after you load the layout. Attached you can find a sample project, where I am initially loading the layout and the approach works correctly.

If you continue experiencing issues, please get back to me with a sample where it can be reproduced, so I can investigate the particular case and help you with it.

Hi Stefan,

Thank you for your suggestions. I moved the event subscription part after loading the layout and now the event will be fired as I expected.

Hello

To follow up on the above,
Is there a way to get the gridview that fired the radpropertychanged event,
i.e. to get the "myGrid" from the sender of the event

I can get the column:
Dim col as gridviewcolumn = trycast(sender,GridViewColumn)
but I dont see how to get the gridview itself ?

This would allow me to have a genereric handler for all the grids in my project.

Thanks in advance

Pierre-Jean

Hello Pierre-Jean,

Please refer to the following code snippet which demonstrates how you can access the RadGridView when handling the column.RadPropertyChanged event:

void column_RadPropertyChanged(object sender, Telerik.WinControls.RadPropertyChangedEventArgs e)
{
    GridViewColumn col = sender as GridViewColumn;
    RadGridView grid = col.OwnerTemplate.MasterTemplate.Owner;
}

I hope this helps. Should you have any other questions do not hesitate to ask.

Regards,
Nadya
