FilterDescriptors

[Victoria F]

dgv_format.DataSource = dtSource;
dgv_format.MasterTemplate.FilterDescriptors.Clear();
FilterDescriptor filter = new FilterDescriptor();
filter.PropertyName = "a_layer_number";
filter.Operator = FilterOperator.IsEqualTo;
filter.Value = 1 ;
filter.IsFilterEditor = true;
dgv_format.MasterTemplate.FilterDescriptors.Add(filter);
dgv_format.Refresh();

Does not filter ....
What could be wrong here ?
I tried to filter not using MasterTemplate  .. also does not filter, does not work :
dgv_format.FilterDescriptors.Add(filter);

Thank you ,
Victoria.

Hi Victoria,

This is striaght from the docs at this link

FilterDescriptor filter = new FilterDescriptor();
filter.PropertyName = "ProductName";
filter.Operator = FilterOperator.Contains;
filter.Value = "Qu";
filter.IsFilterEditor = true;
this.radGridView1.FilterDescriptors.Add(filter);

In your example, what is the PropertyName set to? I think this needs to be the column name and not the FieldName.

Let me know if that helps or if you need more information
Regards,
Richard

Hi again,

There you go, just to verify it must be the column name and not the field name, this works

Private Sub Form1_Load(ByVal sender As System.Object,
                       ByVal e As System.EventArgs) Handles MyBase.Load
    Me.RadGridView1.MultiSelect = True
    Me.RadGridView1.AllowRowResize = False
    Me.RadGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill
    Me.RadGridView1.Columns.Add(New GridViewTextBoxColumn("A"))
    Me.RadGridView1.Columns.Add(New GridViewDecimalColumn("B"))
    Me.RadGridView1.Columns("A").FieldName = "AColumn"
    Me.RadGridView1.Columns("B").FieldName = "BColumn"
    Dim rowInfo As GridViewRowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A1"
    rowInfo.Cells(1).Value = 2.99
    rowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A2"
    rowInfo.Cells(1).Value = 3.99
    rowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A3"
    rowInfo.Cells(1).Value = 635
    rowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A4"
    rowInfo.Cells(1).Value = 635
    Me.RadGridView1.BestFitColumns()
    ' Enable Filtering
    Me.RadGridView1.EnableFiltering = True
    Dim filter As New FilterDescriptor()
    'filter.PropertyName = "AColumn" // No - must be column name
    filter.PropertyName = "A"
    filter.[Operator] = FilterOperator.Contains
    filter.Value = "A2"
    filter.IsFilterEditor = True
    Me.RadGridView1.FilterDescriptors.Add(filter)
End Sub

Sorry it's in VB, but the principal is the same

Richard , thank you very much for your quick responses ..

I tried this also .. the only difference in my case is numeric column. So I'm filtering Int16 column.
In debugger it 's perfect FilterDescriptors = " a_layer_number = 1 " . That's what I'm expecting.. but  dgv_format.FilterDescriptors.Add(filter); does not do anything..
Is it possible that I set some properties on the gridview that prevent filtering ?

Thank you
Victoria.

Have you turned on EnableFiltering?

this.radGridView1.EnableFiltering = true
;

Hi Victoria,

This also works, setting the filter on the GridViewDecimalColumn and giving the filter an integer value

Private Sub Form1_Load(ByVal sender As System.Object,
                       ByVal e As System.EventArgs) Handles MyBase.Load
    Me.RadGridView1.MultiSelect = True
    Me.RadGridView1.AllowRowResize = False
    Me.RadGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill
    Me.RadGridView1.Columns.Add(New GridViewTextBoxColumn("A"))
    Me.RadGridView1.Columns.Add(New GridViewDecimalColumn("B"))
    Me.RadGridView1.Columns("A").FieldName = "AColumn"
    Me.RadGridView1.Columns("B").FieldName = "BColumn"
    Dim rowInfo As GridViewRowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A1"
    rowInfo.Cells(1).Value = 3
    rowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A2"
    rowInfo.Cells(1).Value = 4
    rowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A3"
    rowInfo.Cells(1).Value = 5
    rowInfo = Me.RadGridView1.Rows.AddNew()
    rowInfo.Cells(0).Value = "A4"
    rowInfo.Cells(1).Value = 6
    Me.RadGridView1.BestFitColumns()
    '' Enable Filtering
    Me.RadGridView1.EnableFiltering = True
    Dim filter As New FilterDescriptor()
    'filter.PropertyName = "AColumn" // No - must be column name
    filter.PropertyName = "B"
    filter.[Operator] = FilterOperator.IsEqualTo
    filter.Value = 4
    filter.IsFilterEditor = True
    Me.RadGridView1.FilterDescriptors.Add(filter)
End Sub

let me know if you need more help

Ah, great. We posted at the same time :o)
Glad that's sorted.
All the best
