Default filter problem

[itWorks itWorks]

Hello experts!

I have a GridView, with a column that is filtered like this:

protected override void OnLoad(EventArgs e)
{
     base.OnLoad(e);
     ..............
     gridview1.DataSource = data;
    
     string fString = "filter";
     FilterExpression filter = new FilterExpression(FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, fString.ToString());
     gridview1.Columns["filtered_column"].Filter = filter;
     ...............
}

It works fine, but when I try to set the No Filter option to that column, it does nothing. It's supposed to show all the rows, but it still shows the filtered ones.

How I can solve this?

Thanks for your help!

Hello itWorks itWorks,

Thank you for your question. Please change your code in the following way.

...
FilterExpression filter = new FilterExpression(FilterExpression.BinaryOperation.AND, GridKnownFunction.Contains, GridFilterCellElement.ParameterName);
filter.Parameters.Add(GridFilterCellElement.ParameterName, fString.ToString());
...

We will update our documentation to reflect this code. Do not hesitate to write me back if you have further questions.

Kind regards,
