I'm sure I'm missing something very simple here but I want to add a RadDropDownList to a RadGridView at design time but can't find where I change the default RadGridViewTextBox column to something else. I've looked at several code examples for doing this dynamically but want to know how to do it at design time please. I also want to be able to add CheckBox columns etc. but figure once I get an answer to the first question the others will be relatively similar. My environment is WinForms.

Thanks and best regards

Cannot populate a RadDropdownlist

Hello,

I am using a RadDropdownList but for some reason I cannot get the dataset's table to bind to the Raddropdownlist. However when I use a standard windows combobox the data binds ok.

//This doesn't work with the RadDropdownList..."Lookup" is the name of the datatable within the dataset.
DataSet ds = oLkp.GetLookupValues("matterTypeId, matterType", "tblMatterTypes", "matterType");
this.cmbMatterType.DisplayMember = "Lookup.matterType";
this.cmbMatterType.ValueMember = "Lookup.matterType";
this.cmbMatterType.DataSource = ds;

//Same code using a standard winform combobox, this works fine.
this.comboBox1.DisplayMember = "Lookup.matterType";
this.comboBox1.ValueMember = "Lookup.matterTypeId";
this.comboBox1.DataSource = ds;

Is there an extra step to using these new controls or a design time property that must be set....I know this control replaces the RadCombobox. Using 2011.3.11.1116

Thanks,

Kerry

Can't add a RadDock control into a RadPanel

I have RadDock control on a RadForm that i would like to move into a RadPanel. These are my steps:

Select the RadDock.
Cut the RadDock
Drag a RadPanel onto my RadForm
Enlarge the size of the RadPanel
Select the RadPanel, right clik in it and click Paste

Then Visual Studio always throws this error: "Cannot add component of type 'DocumentTabStrip' to container of type 'RadPanel'. "
** I am using Telerik RadControls for WinForms 2011 Q2
How do i add a RadDock Control inside any other container? Is it possible anyway?

Thanks

RadRichTextBox theme and text problems

Hello,

We have two issues with the RichTextBox component:

1/ I can not find the RichTextBox in the Visual Style Builder.... It seems we can apply a theme on this component since in the Proprieties there is an option as "Theme Name". Please let me know where can I find it.

2/ Also when we had a RadRichTextBox in Visual Studio, the text set up in the proprieties doesn't appear in Visual Studio or when we run the form. Any idea why? We need multiline and HTML formatting for the text that's why we chose this component.

Thank you.
Regards,
Ludovic

Problems with BackColor

I'm using the following method to change the background colors on my scheduler cells.

List<SchedulerDayViewElement> dayViews = ((SchedulerDayViewGroupedByResourceElement)radScheduler1.SchedulerElement.ViewElement).GetDayViewElements();

foreach (SchedulerDayViewElement dve in dayViews) {

foreach (SchedulerCellElement sce in dve.DataAreaElement.Table.GetCells()) {

sce.BackColor = Color.FromArgb(230, 230, 230);

}

This is a simplified example, as I have more logic in my application to figure out what colors certain cells should be.

The problem is when I set that BackColor property the whole cell gets all whacked out. From what I can tell, not only is it changing the backcolor, but also the "hoverbackcolor" and the "selectedbackcolor", both of which I have no idea how to set. Or not set, for that matter.

Also, what is BackColor2, BackColor3, BackColor4?

[Solved] CellMouseEnter- & CellMouseLeave-Events?

Are there any of those Events?
I need to change the value of a cell (Databound to BindingList with INotifyPropertyChanged) if the mouse enters a cell and reset the value if the mouse leaves the cell.
How is this possible?
