Is there a way to hide Conditional Formatting?

[Chad Hensley]

When a user right-clicks on a row, I don't want them to see conditional formatting.  Is there a setting or programmatic way to disable or remove it from the list of options?  How about the other options?

Thanks

Chad

Hello Chad Hensley,

Yes, you can do that by subscribing for the ContextMenuOpening event. You can use the following code snippet that removes the desired menu item:

private void radGridView_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    RadMenuItemBase item = this.GetRadMenuItemByText(e.ContextMenu, "Conditional Formatting");
    if (item != null)
    {
        e.ContextMenu.Items.Remove(item);
    }
}

private RadMenuItemBase GetRadMenuItemByText(RadDropDownMenu menu, string title)
{
    foreach (RadMenuItemBase item in menu.Items)
    {
        if (item.Text == title)
        {
            return item;
        }
    }

    return null;
}

This is a dangerous way to remove the item. It would only work when the English language is used. If localization occured it would not work. Is there no way to remove or disable the item based on the name of the menu item not the text. The name of the menu item is usually not localized.

Hi David, 

The RadMenuItemBase does not have a name property. 
Instead, you can get the localized string back from the provider. 

private void radGridView_ContextMenuOpening(object sender, ContextMenuOpeningEventArgs e)
{
    RadMenuItemBase item = this.GetRadMenuItemByText(e.ContextMenu, RadGridLocalizationProvider.CurrentProvider.GetLocalizedString("ConditionalFormattingMenuItem"));
    if (item != null)
    {
        e.ContextMenu.Items.Remove(item);
    }
}

private RadMenuItemBase GetRadMenuItemByText(RadDropDownMenu menu, string title)
{
    foreach (RadMenuItemBase item in menu.Items)
    {
        if (item.Text == title)
        {
            return item;
        }
    }

    return null;
}

This way, it doesn't matter what the menu is localized to, it will always get the correct one. 

Hope that helps

Is there a list of what the names of these items for menus are? This is a much better way that using the English Text property information.

Hi David, 

All the localization strings for the RadGridView can be found here
