Hello,
I use a event View_CreateCell  to set custom filter cell element but the event not fire for all columns in grid. How can I change that?

private void ListaPlikowRadGridView_CreateCell(object sender, GridViewCreateCellEventArgs e)
        {
            if (e.CellType == typeof(GridSearchCellElement))
            {
                e.CellType = typeof(MyGridSearchCellElement);
            }
           
            if (e.CellType == typeof(GridFilterCellElement) && e.Column.GetType() != typeof(GridViewTextBoxColumn))
            {
                e.CellElement = new CustomGridFilterCellElement(e.Column as GridViewDataColumn, e.Row);
            }
        }

Hello everyone,

I have a little problem with the property StartPosition of a radForm.

When I create a radForm which will be opened with ShowDialog as a modal window at runtime, the start position CenterScreen is not applied. Depending on the size I choose, the modal is sometimes not even fully visible on the screen. How can I resolve this?

I've uploaded a test project which shows the problem:

Thank you in advance and have a nice week!

Hi 

I have added points to RadMap and on each point I have placed an image and a text (as shown in the attached screenshot image). 

My questions

1) can I move the text below the point because it is currently on top of the added image ?

2) can I add a background color to the text to make sure it is visible to end users?

The code I am using is below:

Hi.

Is it possible to set the CheckState of a parent node independently of how the child nodes are set? In my code, it won't let me change the state if there are different states in child node.

Here's the code, just a simple form with a RadTreeView named "tree" on it:

Imports Telerik.WinControls
Imports Telerik.WinControls.UI

Public Class frmTest
    Private Sub frmTest_Load(sender As Object, e As EventArgs) Handles Me.Load
        Me.tree.CheckBoxes = True
        Me.tree.AutoCheckChildNodes = False
        Me.tree.TriStateMode = True

        For i As Integer = 1 To 2
            Dim node As New RadTreeNode("Parent " + i.ToString)
            Me.tree.Nodes.Add(node)
            For j As Integer = 1 To 3
                node.Nodes.Add("Child " + j.ToString)
            Next
        Next

        Me.tree.ExpandAll()

    End Sub

    Private Sub tree_NodeMouseClick(sender As Object, e As RadTreeViewMouseEventArgs) Handles tree.NodeMouseClick

        e.Node.Current = True
        Select Case e.Node.CheckState

            Case Enumerations.ToggleState.On
                e.Node.CheckState = Enumerations.ToggleState.Off
            Case Enumerations.ToggleState.Off
                e.Node.CheckState = Enumerations.ToggleState.Indeterminate
            Case Enumerations.ToggleState.Indeterminate
                'won't change the state on a parent node if not all child nodes are checked!
                e.Node.CheckState = Enumerations.ToggleState.On
        End Select
        e.Node.Current = False

    End Sub

    Private Sub tree_NodeCheckedChanging(sender As Object, e As RadTreeViewCancelEventArgs) Handles tree.NodeCheckedChanging
        If Not e.Node.Current Then
            e.Cancel = True
        End If
    End Sub
End Class

Hi,

I have a RadForm. It has a borderwidth of 4,1,4,4. When I inspected, found that there's a FormImageBorderPrimitive and it has a width of 3,0,3,3. I tried changing the visibility of this element but still the border is there. Is there to remove this border and have only border width of 1,1,1,1

Thanks

Hi,

I'm trying to change the size of the buttons in dock window. I tried changing it via RadControlSpy in runtime as well. But it doesn't seem to change. It is always 22px*22px.

I tried the below code

toolTabStrip.AutoHideButton.ImagePrimitive.Size = new Size(14, 14);
toolTabStrip.AutoHideButton.Size = new Size(14, 14);

Is there a way to change these size ?

Thanks

In my ListViewType.DetailsView, RadListView control, I have a simple item format method as follows.

        private static void RlvScanMeterNumber_VisualItemFormatting(object sender, ListViewVisualItemEventArgs e)
        {

            if (e.VisualItem.Selected)
            {
                e.VisualItem.BackColor = Color.Red;
            }
            else
            {
                e.VisualItem.ResetValue(VisualElement.BackColorProperty, ValueResetFlags.None);
            }
        }

Before when I had the reset flag of that ResetValue function set to ValueResetFlags.Local, it DID NOT WORK.

However, after some experimentation, I found that if I used ValueResetFlags.None, it does work!

I am manually adding the list items to the list view, as per the unbound data scenario. So would that have something to do with it?

Why is that?

What do these ValueResetFlags mean?

I am currently changing the background row on my RadListView, when click selected via the visual item formatting event like this:

        private static void RadListView_VisualItemFormatting(object sender, ListViewVisualItemEventArgs e)
        {

            if (e.VisualItem.Selected)
            {
                e.VisualItem.BackColor = Color.Red;
            }
            else
            {
                e.VisualItem.ResetValue(VisualElement.BackColorProperty, ValueResetFlags.None);
            }
        }

This works great when I click on a row to select it. It does change to a red background.

If you click on another row that is not selected, the state does appear to change with the old row reverting back and the new row changing to a red background.

However if you click the same row, the one you just selected, nothing appears to happen.

How can you code up a toggle of a given row's selection state, if you click it once to select and click it again to deselect?

I have a databound radgridview. 

I have added a GridViewHyperLinkColumn as seen below to the grid after the databound.

GridViewHyperlinkColumn col = new GridViewHyperlinkColumn();

On the CellFormatting I have added the follow to show a short text but a different Hyperlink

I have registered

gvResults.HyperlinkOpening += gvResults_HyperlinkOpening;

And perform some items during this that include Opening the link using the ProcessStart.

My issue is the link opens in a browser before the gvResults_Hyperlink event is called.

I DO NOT want the LINK to open automatically, I want the gvResults_HyperLinkOpening event to do the open.

Any suggestions?
