Column chooser event capture

[Shruti]

Hi,
I have a grid with around 40 columns. I have kept the column chooser element active for this grid. Now i have some operations to perform every time a column is added or removed from column chooser. How can i implement this? I tried with the grid paint vent but it causes a delay due to looping checks. Can you suggest me a good alternative please.

Hi Shruti,

You can catch the moment when a column gets into the column chooser or gets out of it by subscribing to the PropertyChanged event of each column and checking whether the event is fired for the IsVisible property:

foreach(GridViewDataColumn col in this.radGridView1.Columns)
{
    col.PropertyChanged += new PropertyChangedEventHandler(col_PropertyChanged);
}

void col_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "IsVisible")
    {
        GridViewDataColumn column = sender as GridViewDataColumn;
        Console.WriteLine(column.Name);
    }
}

I hope this helps.

Kind regards,
