Problem with pinned column and CellFormatting event

In my RadGridView, I've marked one column as pinned. Without any formatting, this column shows up as a sky blue color. When I apply some cell formatting in the RadGridView's CellFormatting event, the cells in the pinned column are white. I presume this is because I'm resetting cell element formatting values for cells that don't meet the formatting criteria. When I mouse over any cells in the RadGridView, it causes the cells in the pinned column to turn blue again. I've thought about adding a check for IsPinned in the CellFormatting event and changing the color to blue myself, but it seems that this should be handled by the ResetValue method. But, before I submit a bug report, I wanted to make sure I shouldn't be doing something differently.

Thanks,
Robert

Private Sub RadGridView1_CellFormatting(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles RadGridView1.CellFormatting

Dim equationFont As New Font("Cambria", 9, FontStyle.Bold Or FontStyle.Italic)

If e.Row.DataBoundItem.Row("EQUATION") = "Y" Then

e.CellElement.Font = equationFont

If gbUseColorCoding Then ' global boolean variable for users to disable colors

e.CellElement.DrawFill = True

e.CellElement.NumberOfColors = 1

e.CellElement.BackColor = Color.PaleGoldenrod

Else

e.CellElement.ResetValue(LightVisualElement.DrawFillProperty)

e.CellElement.ResetValue(LightVisualElement.NumberOfColorsProperty)

e.CellElement.ResetValue(LightVisualElement.BackColorProperty)

End If

Else

e.CellElement.ResetValue(LightVisualElement.FontProperty)

e.CellElement.ResetValue(LightVisualElement.DrawFillProperty)

e.CellElement.ResetValue(LightVisualElement.NumberOfColorsProperty)

e.CellElement.ResetValue(LightVisualElement.BackColorProperty)

GridViewComboBoxColumn Value Only Visible on Edit

Hi,
I have seen variations of this question asked on several different posts, but either the fix has either been irrelevant to my particular situation or the question has gone unanswered. I have created a simplified example that you can run on your own computer, so as to easily demonstrate my problem.

I have a simple class "dog" which contains a property "Breed" of enum type "DogBreeds". I wish to display this value in a GridView combo box, but using more user-friendly text than the enum values.

This is my data class:

Public Class Dog

Private dmName As String

Private dmColour As String

Private dmBreed As DogBreeds

Public Sub New(ByVal _name As String, ByVal _colour As String, ByVal _breed As DogBreeds)

MyBase.New()

dmName = _name

dmColour = _colour

dmBreed = _breed

End Sub

Public Property Name() As String

Get

Return dmName

End Get

Set(ByVal value As String)

dmName = value

End Set

End Property

Public Property Colour() As String

Get

Return dmColour

End Get

Set(ByVal value As String)

dmColour = value

End Set

End Property

Public Property Breed() As DogBreeds

Get

Return dmBreed

End Get

Set(ByVal value As DogBreeds)

dmBreed = value

End Set

End Property

End Class

And my Enum:

Public Enum DogBreeds

Staff

Husky

GShep

End Enum

To demonstrate the problem, create a GridView on a form called "dgv" and add the following code:

'Add some example data

dogs = New List(Of Dog)

dogs.Add(New Dog("Sacha", "Brown", DogBreeds.Staff))

dogs.Add(New Dog("Nimbus", "Black/Brown", DogBreeds.GShep))

dogs.Add(New Dog("Chinook", "White", DogBreeds.Husky))

'Set the grid data source:

dgv.DataSource = dogs

'Create the data source for the combo column, comprosed of a column of the enum and a column of the

' "friendly" string represetion for that enum value

Dim dtBreeds As New DataTable

dtBreeds.Columns.Add("BreedEnum", GetType(DogBreeds))

dtBreeds.Columns.Add("BreedName", GetType(String))

dtBreeds.Rows.Add(DogBreeds.GShep, "German Sheppard")

dtBreeds.Rows.Add(DogBreeds.Husky, "Icelandic Husky")

dtBreeds.Rows.Add(DogBreeds.Staff, "Staffordshire Bull Terrier")

'Set the column display and value members and the data source for the combo

With DirectCast(dgv.Columns("Breed"), GridViewComboBoxColumn)

.DisplayMember = "BreedName"

.ValueMember = "BreedEnum"

.DataSource = dtBreeds

End With

Run the form. All the combos are blank, but when you click on a combo cell, the correct value is displayed, but disappears again when focus is lost from the cell, so it looks like a display bug. I have successfully used this method on a DataGrid, so not sure why it does not work here.

Any help much appreciated

How to insert record into radgrid on the fly

Hi

I want to add record on fly by radgrid.

I have some textbox and two buttons (Insert and Submit) to add information in radgrid.

My senario is:
When user enter her/his info into textbox and click on the insert button, value of textbox must be inserted into radgrid at client side without save them into database. In the final user click on the submit button, then all rows in radgrid save in database.

I see this and this demo online, but in both of them using webservice and bind grid from database.
How I can do my senario?

Thank's

GridViewRowInfo VisualElement

I am new to Telerik so please forgive the beginner question. I have searched the forums for a possible answer but haven't found anything that specifically answers my question.

I am upgrading the Telerik RadControls for Winforms from Q1 2010 SP2 to Q2 2010. There were obviously some things that broke in the code and I think I have fixed them all, but I cannot seem to find a solution for one. The error is the following:

Telerik.WinControls.UI.GridViewRowInfo does not contain a definition for VisualElement and no extension method...blah...

The line of code looks like this:

if (row.Cells["Status"].Value.Equals("complete"))

row.VisualElement.ForeColor = Color.Gray;

How do I address this? What changed between Q1 2010 SP2 and Q2 2010?

Thank you in Advance for any insight. It is greatly appreciated.

Hide expand/collapse button for level 0 nodes

Does anyone know if it Is it possible to hide the expand/collapse button at all? I am trying to preserve as much horizontal space as possible and also fulfill a requirement that the first level of nodes is always expanded.

I've come across a solution for the ASP.NET AJAX suite but nothing for the WinForms (http://www.telerik.com/community/forums/aspnet-ajax/treeview/drop-expand-collapse-image-from-root-node.aspx#854721)

Thanks,
Adam
