Getting the SelectedValue after setting the SelectedItem.Text Programmatically

This has to be a very simple request, but I just started using your RAD Ajax ASP combo box...

I have a combobox that is bound to a list of States.
- I am setting the DataValueField to an integer that is basically an identity value in the database.
- I am setting the DataTextField to the abbreviations of the State.

When a user fills out the form and saves the data to a database, we are saving the DataTextField , not the value field. So, we'd save "NC" or "NY" for instance, instead of the integer of 37 or 39 or whatever corresponds to that state.

BTW: After the user selects a state, I use the SelectedValue to find a list of Counties that belong to that state.

Here is what I don't know how to do:
- In our app, the user can pull up this data to edit it. Since they have previously selected a State, I need to select the value of the state that they had chosen, in the Combobox.

Q. How can I do that? I fill the combo box with a list of States, but if I set the "SelectedItem.Text" to the state abbreviation that they had chosen, it obviously sets the text of the first item in the combobox to their state.
But that is wrong. I want to programmatically select the state that they had selected, in the combox box.

- Since I only have the State abbreviation (the DataTextField) and
not the ID, I can't set the "SelectedValue" (if that would even do what I want).

I guess the question boils down to: If I have a combo box full of string values, how can I programmatically select an item from the combo box, based on that string value?

Thanks,
Brent

Using RadAjaxManager and RadWindowManager on the same page and Session issues

First of all, I have a RadAjaxManager on my page for use with a RadAjaxPanel. These are present so I can make changes to the page after a callback to the server without having to reload the whole page.

I recently added a RadWindowManager so I could make a custom confirmation popup window come up when a user clicks the submit button. If the user clicks OK then I call __doPostBack('<%=this.btnSubmit.ClientID%>','');

In the post back I have the server load some new variables into the session... This all works just fine.

However, after the request is complete, if the user comes back to submit another form the same data remains in the session from the previous visit to the page.

If I remove the popup window and the RadWindowManager all works just fine.

What is going on here?

RadEditor's contextmenu vs RadWindow z-index problem

Hi,

I'd like to describe my problem below:

1. Use Firefox
2. Open modal window (RadWindow) using url of page containing RadEditor control.
3. Set scroll="no" to the page's body

Now, right-click on the editor - context menu should appear. The problem is because it should be displayed in front of radwindow (just like it is in IE). Instead it makes the inner page's scrollbars appear and is partially hidden under its parent window. I tried to set the highest z-index property and position to absolute with no avail

Regards,
Rycho

Textbox can't focus on modal popup

Hi.

I have a modal pupup. Inside that, i have another button, that opens up a new modal poup window with a RadEditor. If i click in the textfield inside the radeditor, closes the popup, and in the first modal popup opens another window with a textbox, it is not possible for me to set the mose courser inside the field. It is not displayed, and the text typed is not displayed either.

To explain the obove:

Page
- Popup (opens first)
  - Popup with Rade editor (opens second)
  - Popup with textbox (opens third).

It only happens if i use IE7, and not in FireFox.
