My project requires me to have an expand/collapse feature (like the tree view), but my content isn't text - it's a bunch of labels and gridviews. Is there a way to implement this with the tree view? Users want the +/- feature, but my content isn't like what's posted on the examples. How would I go about accomplishing this?

[Solved] Bug in AllowResize

I want my grid to fill to the full available size. I also don't want the user to be able to adjust the column widths. There is a bug in the grid that does not allow both of these features.

If you try the sample code below, you will see that the grid automatically fills to the available size. Then uncomment out the two "AllowResize" lines and you will see that the grid no longer automatically fills to the available size.

Is there a way to both fill and prevent the user from resizing the grid columns? THANKS

Imports Telerik.WinControls.UI

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim people As New List(Of Person) From {New Person(1, "Richard"), New Person(2, "Peter"), New Person(3, "Chris")}

Me.radgridview1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill

Dim column1 As New GridViewTextBoxColumn("Column 1")

'column1.AllowResize = False

Dim column2 As New GridViewComboBoxColumn("Column 2")

column2.Width = 100

column2.FieldName = "Id"

column2.DataSource = people

column2.DisplayMember = "Name"

column2.ValueMember = "Id"

'column2.AllowResize = False

Me.radgridview1.Columns.Add(column1)

Me.radgridview1.Columns.Add(column2)

' Populate the cells

Dim rowInfo As GridViewRowInfo = Me.radgridview1.Rows.AddNew()

rowInfo.Cells(0).Value = "A1"

rowInfo.Cells(1).Value = 1

rowInfo = Me.radgridview1.Rows.AddNew()

rowInfo.Cells("A").Value = "A2"

rowInfo.Cells("B").Value = 2

End Sub

End Class

Public Class Person

Public Sub New(ByVal Id As Integer, ByVal Name As String)

Me.Name = Name

Me.Id = Id

End Sub

Public Property Name As String

Public Property Id As Integer

End Class

Help me,get data from database into bombobox

Dear ...,
My problem is:
In my database, I have "CLASS" table. This table has 3 column: ClassID, ClassName and ManagerID

Now, I want to show all ClassIDs that have the same ManagerID on Combobox.

My code:

public class Classes

{

private int id;

private string name;

public string Name

{

get { return name; }

set { name = value; }

}

public int ID

{

get { return id; }

set { id = value; }

}

public override string ToString()

{

return id.ToString();

}

private void LoadDataTocbClass()

{

cbClass.FindItemExact("hello");

for (int i = 0; i < PrepareDataForcbClass().Count; i++)

{

cbClass.Items.Add(PrepareDataForcbClass()[i]); // ERROR, WHY?

}

cbClass.DisplayMember = ("Name");

}

private List<Classes> PrepareDataForcbClass()

{

List<Classes> list = new List<Classes>();

string sql = "select ClassID FROM [AttendanceDB].[dbo].[CLASS]" +

"where ManagerID=@ManagerID";

SqlCommand myCommand = new SqlCommand();

myCommand.Connection = myConnection;

myCommand.CommandText = sql;

myCommand.Parameters.AddWithValue("@ManagerID", ManagerID);

myConnection.Open();

SqlDataReader myDataReader = myCommand.ExecuteReader();

Classes cl;

while (myDataReader.Read())

{

cl = new Classes();

cl.Name = myDataReader.GetString(0).ToString();

list.Add(cl);

}

myDataReader.Close();

myConnection.Close();

return list;

}

Can you help me write an example or help me fix my code.

Which DDL fired the Selected Value Changed?

Hello,

I'm trying to implement the following code

Private Sub combo_SelectedValueChanged(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.Data.PositionChangedEventArgs) Handles

cmbManager.SelectedIndexChanged, cmbYear.SelectedIndexChanged, cmbStatus.SelectedIndexChanged, cmbProductFamily.SelectedIndexChanged, cmbCommmodity.SelectedIndexChanged

Try

dtData.Rows(0).Item(sender.Tag) = sender.SelectedValue

bEdited = True

Catch ex As Exception

Stop

End Try

End Sub

However the sender in this event is NOT the RadDropDownList, it is a RadListElement and I cannot find a way to figure out which dropdown the element came from.

Can anyone assist me? I really hope I'm just overlooking something obvious.

Thanks!
Matthew

RadDropDownList rounded corners

We are trying to round off the corners of the majority of controls in all themes.
We are finally getting there by setting different backgrounds as transparent but we are having a problem with the raddropdownlist.

When the control drops down we are seeing the white background behind the list.

I have attached an image which hopefully shows what I mean.

How do we set the background of this dropdown to be transparent and rounded.

I thought you may be using the radlistcontrol but this is set to be rounded and transparent and works.
Radpanel is also transparent and rounded which also works.

We have also found that if you set the
RadDropDownList
RadDropDownListElement
RadDropDownListEditableAreaElement
BackColor to be transparent in the style builder, this effect is not brought through to the front end when the theme is loaded.

Hope someone can shed some light on this.

Regards,

Graeme.

[Solved] Could not load file or assembly Telerik.WinControls.Scheduler

I'm in the long process of upgrading my project from Q1 2010 to Q1 2011, and am running into the following error with a form that uses the Scheduler:

Error 1 Type in the data at line 152, position 5, cannot be loaded because it threw the following exception during construction: Could not load file or assembly 'Telerik.WinControls.Scheduler, Version=2010.1.10.409, Culture=neutral, PublicKeyToken=5bb2a467cbec794e' or one of its dependencies. The system cannot find the file specified.

For some reason, it's looking for the previous version of the control even though the assemblies (including Telerik,WinControls.Scheduler) are all the Q1 '11 versions. This seems to be the only Telerik control that's having this type of issue with the upgrade. What is the issue?
Thanks,
Jeremy
