[Solved] Context menu doesnt display all values

[Sonu]

Hi

In my telerik grid view I am displaying around 50K rows. When I click on the column context menu I does not get all the values. Is there any limitation in the context menu item display?

In the screen shot I have expanded context menu for column "Period 9". But as you can see it displays values till -25,547.64 (ordered  ascending) but I have have positive values as well, its not even displaying all negative values. Please see the screen shot


Thanks
Sonu

Hello Sonu,

For performance reasons we are loading the first 1000 items in the distinct values filter. If you need to show all the data you can subscribe to the DistinctValuesLoading event of the gridview and set the e.ItemsSource to whatever you want.
Here is an example:

public MainPage()
{
    InitializeComponent();

    this.testGrid.ItemsSource = MyData();
    this.testGrid.DistinctValuesLoading += new EventHandler<GridViewDistinctValuesLoadingEventArgs>(testGrid_DistinctValuesLoading);
}

void testGrid_DistinctValuesLoading(object sender, GridViewDistinctValuesLoadingEventArgs e)
{
    if (e.Column.Header.ToString() == "Int32")
    {
        e.ItemsSource = this.MyData();
    }
}

List<int> MyData()
{
    return Enumerable.Range(0, 2000).ToList();
}

Hope this helps.

Kind regards,
