Change default selectedItem to "Contains" when FieldFilterEditorCreated event triggers

[Victor]

Hi,

First of all, excuse me for my poor english skills.

When I click on the FilterEditor of a GridView the default value of the field "Show rows with value that" is "Is equal to" and I would like to change the default value to "Contains".

Is there any way to achieve what I'm trying to do? Could you explain me how to implement it, please?

Thanks in advance.

PS- I hope you understand what I meant, if not, don't hesitate to ask.

I've found a solution for Telerik versions after the Q3 2011, but I don't know how to achieve the solution with versions before Q3 2011.

Could anybody help me, pleaz???

"The FilterOperatorsLoading event (Added Q3 2011) allows you to both remove unwanted operators and define a defaultly selected operator in a proper way. "

C#

private void GridView_FilterOperatorsLoading(object sender, Telerik.Windows.Controls.GridView.FilterOperatorsLoadingEventArgs e)
{
    if (e.AvailableOperators.Contains(FilterOperator.Contains))
    {
        e.DefaultOperator = FilterOperator.Contains;
    }
}

Hi,

I am afraid that you will have to upgrade if you want that functionality. The older versions do not have it and you cannot change the filter operator.

Thanks for the answer Ross. I guess I'll have to upgrade your product. Regards.

Hi

I used following EventHandler to set DefaultFilter 1 & 2:

            FilterOperatorsLoading += (sender, args) =>
            {
                args.DefaultOperator1 = FilterOperator.Contains;
                args.DefaultOperator2 = FilterOperator.Contains;
            };


But it seems that hitting ClearFilters resets the DefaultOperators to IsEqualTo...
Best regards

Hi Sven,

This will not happen with the latest version - Q2 2012 SP1. Please give it a try and let us know if you still have problem.

I am new to .net and Rad controls and need to implement something similar to:
FilterOperatorsLoading += (sender, args) =>
            {
                args.DefaultOperator1 = FilterOperator.Contains;
                args.DefaultOperator2 = FilterOperator.Contains;
            };
but I need to know what context this code should appear in.  Should this go in the contructor of the viewmodel for the view on which the RadGridView is implemented?
