Clear "FieldFilter" value in column filter description

[Beata]

Hi,

How can clear the "FieldFilter" value?

I have set FilteringMode="FilterRow" on my grid.

 

Until now I tried:

foreach (var column in gridWithFilters.Columns)
{
    column.ClearFilters();
    column.ColumnFilterDescriptor.Clear();
  column.ColumnFilterDescriptor.FieldFilter.Clear();
}

but this clear the filter, but not its value!

 

I have also tried:

foreach (var column in gridWithFilters.Columns)
{
    IColumnFilterDescriptor countryFilter = column.ColumnFilterDescriptor;
    countryFilter.SuspendNotifications();
    column.ColumnFilterDescriptor.FieldFilter.Filter1.Value = "";
    column.ColumnFilterDescriptor.FieldFilter.Filter1.Operator = FilterOperator.Contains;
    countryFilter.ResumeNotifications();
}

but I get an error: "Input string was not in a correct format."

 

Is it possible to clear the "FieldFilter" value?

 

Thanks!

Beata

Hello Beata,

Thank you for the provided code. 

May I ask you some additional questions in order to better assist you? Can you specify what you mean by clearing the "FieldFilter" value? 

I tested the first approach on my side and the column filters are correctly cleared. I am attaching the sample project that I used for your reference. May I ask you to take a look at it and let me know if you are doing something different on your side? If you can specify what is the result you are expecting and potentially provide a sample picture, I will be able to better understand the described scenario.

I am looking forward to your reply.

Hi Vladimir,

Thank you for the sample project, it helped me to solve my problem!

Your project has got the same issue which mine has..

The problem is when an user enters the search text, chooses "Clear Filters" operator and click "Click Filters" button... then *.Clear() and *.ClearFilters() do not clear the search text (column.ColumnFilterDescriptor.FieldFilter.Filter1.Value).

 

In order to clear the search text when "Clear Filter" operator is selected I have to programatically set the operator (for example FilterOperator.Contains).

 

Thanks,

Beata
