Conditional formatting problems.

Hi.

I get problems with conditional formatting.

In the case that you want to set font color (CellForeColor) that depending on the column condition and you set property ‘Apply to row’ is true and also if you create second condition that changing row back color you will lose CellForeColor setup from first condition.

Is it possible to change dynamically “row back color” without using conditional formatting?

When i run the app, I first get to see "AutoAnswerComboBox" and then on click on the combo box, I see the actuall 2 elements.

By default, I want user to first see "On" instead of "AutoAnswerComboBox".

Can you please tell me how to set the first comboboxitem as the first displayed item to the user?

Handle DocumentPanel closing Event

Hi,

I'm using registered version of Rad Controls for WinForms SP2, in particular I'm using DockingManager control.
I have some some dockPanels and some documentPanels. I would like to handle documentPanel_closing events. (Ex: to check if the content was saved by user)

I use the following code:

[DESIGNER - Auto Generated Code]
this.documentPane_Benvenuto.Closing += new System.ComponentModel.CancelEventHandler(this.documentPane_Benvenuto_Closing);

[FORM]
private void documentPane_Benvenuto_Closing(object sender, CancelEventArgs e)
{
MessageBox.Show("documentPane_Benvenuto is closing..");
}

This code doesn't work. When i close the documentPane_Benvenuto the event isn't raised. If i set one breakpoint in the method documentPane_Benvenuto_Closing(...) nothing happen, the method isn't executed.
What is the best way to solve my problem? There is a simple solution o work around to do this?

Thank you very much for support.

Embedded GridView Object

In the online documentation, I saw a page where there is a GridView embedded inside another GridView Object. I was wondering when it is possible to do embedded GridView? This feature is one of the features that attracted me to purchase this control. The below link has an image of what I am talking about (it is under Hierarchical data presentation).

http://www.telerik.com/help/winforms/Q2_2007/grd_Overview_Overview.html

if it is already possible to use this feature, can someone please provide some sample code? Thank you!

Also, is there a new version coming out? If so, when is the release date? Thank you!

Cannot bind to KeyValueConfigurationCollection

Hi, I try to bind a gridview to an instance of KeyValueConfigurationCollection as follows:

private void WebHRSnifferForm_Load(object sender, EventArgs e)
{
dataBind104ComSettingGrid();

        }
        private void dataBind104ComSettingGrid()
        {
            // QueryStringParams is type of KeyValueConfigurationCollection
            Grid104CompSetting.DataSource = webHRConfig.OneZeroFour.Company.QueryStringParams.GetEnumerator();
        }

But it seems the girdview cannot locate the properties exposed by KeyValueConfigurationElement that is contained within KeyValueConfigurationCollection. So no columns are created.

Is there anything I should implement to let gridview bind to KeyValueConfigurationCollection.

Thanks a lot.
Ricky.

Problem with Delete row

I noticed that some other folks were having a similar issue, but not the same issue I am having. I am binding my RadGridView to a Generic List. When I delete the item in the Generic List and rebind the row doesn't remove until I scroll the deleted row out of view and then back into view.

The item is removed, but the physical row is still on the grid. It throws the following exception:

The following exception occurred in the RadGridView:  

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.  

Parameter name: index  

   at System.ThrowHelper.ThrowArgumentOutOfRangeException(ExceptionArgument argument, ExceptionResource resource)  

   at System.ThrowHelper.ThrowArgumentOutOfRangeException()  

   at System.Collections.Generic.List`1.System.Collections.IList.get_Item(Int32 index)  

   at Telerik.WinControls.UI.GridViewData.GetValue(Int32 boundColumnIndex, Int32 columnIndex, Int32 rowIndex)

Sample Code to reproduce the error:

' in form load, the grid is bound to the genericList  

private sub frm_frmLoad()  

  Me.radGridView.DataSource = genericList  

End Sub 

public sub RemoveItemFromList(ByVal customItemToRemove as CustomItems)  

  ' remove item from the List(Of CustomItems)  

  If genericList.Contains(customItemToRemove) Then 

    genericList.RemoveAt(genericList.IndexOf(customItemToRemove))  

  End If 

  ' rebind to   

  Me.radGridView.DataSource = genericList  

End Sub

I am currently using Q1 2007 with VS2005 SP1.

Thanks for a great product and any thoughts on this.

Row selection only

It there a way to deactivate the selection of dates from the individule days on the calendar? This way the only way anyone could select anything it would be on a week-by-week basis (via the row (week) number). Then be able to pull the dates that were selected from that row?

Calendar, DateTimePicker, TimePicker and Clock
