[Solved] using gridview in a trading application - quotes in specific

Hi,

Has anyone used this control in this scenario, uses this control to display quotes, in an active market.

We all know what the stock quote gride consist of, so i wont elaborate on that. My issues are that the gridview is using too much cpu when updating quotes as it arrives. on each page of quotes, i have a max of 25 rows of data that i'm watching, if all are updating at the a rate of 25ms, my cpu utilization is at around 60%, i don't think this is normal unless i'm doing something wrong.

can someone shed some light on this subject?

Thanks,

GridView

[Solved] OldRow, Current Row, MultiColumnComboBox

Hello

I am using visual studio with c sharp, windorm and latest Rad controls.

I have a multcolumncombobox named mcbUserReports. Within it's SelectedIndexChanged event I want to be able to move the selected index to the OldRow. I understand that it is connnected to the CurrentRowChangedEventArgs. I am having a difficult time assign it's properties to an object which will allow me to tap into the OldRow and CurrentRow values. This is what I have thus far:

Private Void mcbUserReports_SelectedIndexChanged(object sender, EventArgs e)
}
Telerik.WinControls.UI.CurrentRowChangedEventArgs objTelerikEventArgs = //(not sure what to put here)
Int32 intOldRow = objTelerikEventArgs.OldRow.Index:
}

The first line within the SelectedIndexChanged block should read below:

Thanks

[Solved] Problem with visible/invisible ToolWindow in RadDock with SaveLayout

Good morning.
I have found something strange in the behavior of your RadDock control. I create a simple test project: a Windows Form Application with one RadMenu and one RadDock. In the RadDock I add a new ToolWindow to the left, in the RadMenu I add only one MenuItem. Here's the code (Visual Basic Express 2008 in a Windows XP SP3 environment, Telerik RadControls WinForms Q3 2010):

Imports Telerik.WinControls.UI.Docking

Public Class Form1

Private file As String = "a.xml"

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

Me.Visible = False

If (System.IO.File.Exists(file)) Then RadDock1.LoadFromXml(file)

RadDock1.Visible = False

Me.Visible = True

End Sub

Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

RadDock1.SaveToXml(file)

End Sub

Private Sub RadMenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadMenuItem1.Click

Static flag As Boolean

If flag Then

RadDock1.Visible = False

Else

RadDock1.Visible = True

End If

flag = Not flag

End Sub

End Class

Now do the following:
1. Run the project.
2. Clik on the RadMenuItem1.
3. Set the ToolWindow Floating.
4. Close the form.
5. Run the project again: the ToolWindow is visible even if the RadDock control isn't.
How can I hide floating windows on startup? And make them visible again when RadDock1.Visible = True?

Thank you very much
Gianfranco

[Solved] Assigning multiple DropDownLists

This is probably going to seem pretty easy to some of you but I haven't been able to determine what the cause of this problem is. If I try to set a RadListDataItem object and add that object to multiple DropDownList controls it doesn't work. For instance, I have a simple For/Next loop that enumerates a list of COM ports. Seems to me that I should be able to do a simple loop and add the items as shown below but it doesn't work. Only one of the DropDownLists gets the data. I'm sure it has something to do with the way the control is handling the dataitem objects. I'm hoping someone can explain it to me and give a work around other than creating two For/Next loops (one for each DropDownList).

Thanks!

For i As Integer = 0 To 9

Dim oItem As New RadListDataItem

oItem.Text = "COM" & i

oItem.Value = "COM" & i

rddReceiveCOM.Items.Add(oItem)

rddSendCOM.Items.Add(oItem)

oItem = Nothing

Next

DropDownList
