[Solved] Problem with selectionstate of a specific filter column

[Frank Schürer]

Hi,

i am currently implementing a custom filter dropdown with radgridview, but i get confused with the following problem.

For simplification just imagine i have two columns, Status and Status2.
Status is just a representation of 0 or 1. Status2 is an image representing the status.

If i click the filter symbol inside of the TableFilteringRow my custom dropdown will be opened.
After choosing an option a handler fires and the filter is being applied to the column "Status".
That works as i would expect it.

But if i try that the second time, my custom dropdown shows up, i choose another option,
the handler fires but the filter symbol seems to be still pressed. And that is the reason why the data inside the gridview cannot be filtered because the filter action is not yet finished until i click into another column/row.

See also the attached image for better understanding what i mean.

Here is the code:

Private Sub grdViewPostleitregion_ContextMenuOpening(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.ContextMenuOpeningEventArgs) Handles grdViewPostleitregion.ContextMenuOpening

        If (e.ContextMenuProvider Is Nothing) Then

 

            e.ContextMenu.Items.Clear()

 

            Dim dtMenu As New RadDropDownMenu

 

            Dim r As RadMenuItem

            Dim sepItm As RadMenuSeparatorItem

 

            'No Filter

            r = New RadMenuItem

            r.Text = "No Filter"

            dtMenu.Items.Add(r)

            AddHandler r.Click, AddressOf PostRegionNoFilter_Click

            'Separator

            sepItm = New RadMenuSeparatorItem

            e.ContextMenu.Items.Add(sepItm)

 

            'Imagefilter

            r = New RadMenuItem

            r.Image = My.Resources.Status_0

            r.Text = "OK"

            dtMenu.Items.Add(r)

            AddHandler r.Click, AddressOf PostRegionStatus0_Click

 

            r = New RadMenuItem

            r.Image = My.Resources.Status_1

            r.Text = "Warning"

            dtMenu.Items.Add(r)

            AddHandler r.Click, AddressOf PostRegionStatus1_Click

 

            e.ContextMenu = dtMenu

 

        End If

    End Sub

 

    Private Sub NoFilter_Click(ByVal sender As Object, ByVal e As System.EventArgs)

        With Me.grdViewPostleitregion

            .Columns("Status").FilterDescriptor = Nothing

 

            .CurrentColumn = .Columns("Status")

            .CurrentRow = .MasterView.TableFilteringRow

        End With

    End Sub

 

    Private Sub Status0_Click(ByVal sender As Object, ByVal e As System.EventArgs)

        Dim Filter As New FilterDescriptor()

 

        Filter.Operator = FilterOperator.IsEqualTo

        Filter.Value = 0

        Filter.IsFilterEditor = False

        With Me.grdViewPostleitregion

 

            .Columns("Status").FilterDescriptor = Nothing

            .Columns("Status").FilterDescriptor = Filter

 

            .CurrentColumn = .Columns("Status")

            .CurrentRow = .MasterView.TableFilteringRow

 

            .MasterView.TableFilteringRow.Cells(0).IsSelected = True

 

        End With

    End Sub

 

    Private Sub Status1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

        Dim Filter As New FilterDescriptor()

 

        Filter.Operator = FilterOperator.IsEqualTo

        Filter.Value = 1

        Filter.IsFilterEditor = False

 

        With Me.grdViewPostleitregion

 

            .Columns("Status").FilterDescriptor = Filter

            .CurrentColumn = .Columns("Status")

            .CurrentRow = .MasterView.TableFilteringRow

 

            .MasterView.TableFilteringRow.Cells(0).IsSelected = True

        End With

    End Sub

How can i fix that?

Hello Frank,

I would like to ask you what version of telerik controls are you using, because i've tried your code (modified it to C# ) and i couldn't reproduce the problem you've been talking about, please try to update to the latest version and try this code and after that let me know if you still have this problem.

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            radGridView1.EnableFiltering = true;
            radGridView1.ContextMenuOpening += radGridView1_ContextMenuOpening;
            radGridView1.DataSource = new TestsCollection();
        }

        private void radGridView1_ContextMenuOpening(System.Object sender, Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)
        {
            if (e.ContextMenuProvider == null)
            {
                e.ContextMenu.Items.Clear();

                RadDropDownMenu dtMenu = new RadDropDownMenu();

                RadMenuItem r = default(RadMenuItem);
                RadMenuSeparatorItem sepItm = default(RadMenuSeparatorItem);

                //No Filter
                r = new RadMenuItem();
                r.Text = "No Filter";
                dtMenu.Items.Add(r);
                r.Click += NoFilter_Click;
                //Separator
                sepItm = new RadMenuSeparatorItem();
                e.ContextMenu.Items.Add(sepItm);

                //Imagefilter
                r = new RadMenuItem();
                r.Text = "OK";
                dtMenu.Items.Add(r);

                dtMenu.Items.Add(r);
                r.Click += Status1_Click;

                this.radGridView1.CurrentRow = this.radGridView1.MasterView.TableFilteringRow;
            }

                this.radGridView1.CurrentRow = this.radGridView1.MasterView.TableFilteringRow;

    public class Test
    {
        public int Id { get; set; }

        public int Status { get; set; }

        public TestsCollection()
        {
            for (int i = 0; i < 10; i++)
            {
                this.Add(new Test { Id = i, Status = i % 2 == 0 ? 0 : 1 });
            }
        }
    }

Hi Frank,

Thank you for your code.

Just like Emanuel, I am unable to reproduce the described issue with a custom filter menu. I have tested the case with a code snippet similar to yours and everything seems to work as expected on my side.

Could you please open a new support ticket and send us a small sample project? This will help to investigate your particular scenario further and provide you with accurate assistance.

Greetings,
