Hello,
I´m working with radgridview for winforms, I'm a begginer in it, and I have a problem, I don't know how to populate the template of de grid, I try with this code:
but it doesn't work as I expected, when I expanded the principal grid, the template(or de child grid) is empty, so the function Obtener_DetalleViaje return information... I'm not shure it is the way to populate it, someone can help me?
I hope to be clear, thanks in advance

I would like to be able to use the expression editor as a stand-alone component. I've been playing with both the WinForms and WPF versions.
I do realize the WinForms version doesn't directly support standalone operation, so what I've done is created a RadGridView and made it invisible. I add some columns programmatically, and enable expression editing on the first one (only).
Then I have a button which launches the expression editor:
RadExpressionEditorForm.Show(grid1, grid1.Columns[0]);
Which does bring up the expression editor, and I see the other columns I've defined in the "Fields" list.
But the method RadExpressionEditor.Show() method is not modal -- it returns immediately, and I don't see an alternate ShowDialog() signature. Also, the method returns void, so I don't know whether the user pressed Cancel or OK.
I'm guessing that what I should do is handle some event on the grid view to know when the dialog has been dismissed ... but I've tried several, including CellValueChanged() and CellEndEdit(), and they don't ever seem to get called.
What am I doing wrong?!?

I have an application that is a mdi and on the parent I have a radmenu and on that is a RadMenuComboBoxItem that the user can select the client they want to work with. I have it setup so that when the user selects a screen the screen loads based on the client that has been selected on the screen. But there are time the user is going to be doing work on the child and want to change the Client on the parent form. How can I access the item on the parent from the mdi child? I can get form, I can get the radmuneitem, but I have not been able to access the RadMenuComboBoxItem.

Hello!
I use a non-Telerik form to add/edit Appointments. I want to use Telerik's Edit Recurrence dialog instead of creating a whole new form like I did for adding/editing appointments. I want to do something like:
I would assume that once the dialog exits, I would be able to retrieve the recurrence rule from the appointment that I passed in's RecurrenceRule property, but the dialog closes right after it opens, and then returns a null exception when I access the RecurrenceRule property since I didn't get to create a recurrence rule with the form. Any help would be appreciated! Thanks!

I have a RadGridView that I set the datasource at run time. When I export it all the rows that are visible on the screen export fine, however the ones you can't see the excel row height is 3.75 pixels. (See attached screen shot) How do I get the export to export the correct format of all rows not just the ones visible? One other side note is if I scroll through the list and then export it exports correctly.
this.tSQL = "EXEC dbo.GetDetailsForCodeType '" + strSelectedCode + "','" + strSelectedCodeType + "'";
DataTable dtMarketDetails = this.da.GetDataTable(this.tSQL);
this.dgMarketDetails.DataSource = dtMarketDetails;
As a test I setup another GridView and pre set the data source and that exports just fine.

I'm currently using a RadDropDownList with a set of DescriptionTextListDataItems in DropDownList mode and it looks great except that it's drawing a thin gray separator line between the item text and the item description like this:
Is there a way to remove this separator line and to have a separator line between the list items? What I'm looking for is something like this:
I'm not sure the way I'm doing it now is correct or the preferred way.

To whom it may concern,
we are evaluating your GridView component. However, just found the gridview control keeps freezing?
See attached sample project, did I do something wrong?
Any of your reply will be highly appreciated, thank you!

I am creating an appliaction that I have a main form and then a RadPanel that depending on what the user selects from the menu will then load a user control(form) into the panel. But I need to access data from the main form. My question is, is this a good design or is the re a bteer way to have screen s load into the app. Also if this a good design how do I get values from a dropdown on the main form when the child loads, and then if I change the value on the dropdown how do I get the child control to reload based on the value in the dropdown.
