View 6 RepliesIs it possible to someshow select "child" controls of an <asp:Table> control so that I can view and set properties of the "child" control while in designer view? Its a real pain to have to edit properties of a child control in the source view. What I ultimately seem to end up doing is having to place or move any controls inside an asp:Table that I want to set properties on to the "outside" of the table and set all the properties on the control. After all the properties are on set on the control, using the designer,I can move it back inside the asp:Table. This is not the most troublesome of options but it would be nice if you could somehow set the properties of child controls using the designer.

I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?
I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.
I have a problem with CascadingDropDown... I have two related comboboxes, where the second is a slave of the first (e.g. country the first, cities the second). What I want is that if I select one country from combobox 1 then the second must be "filtered" by that selection (it should display all the cities inside the selected country, and the actual CascadingDropDown implementation is OK), but if I leave the combobox 1 in the default option (e.g. "Please select a country") I want the second to display all the cities I have in the database. The problem is that when selecting default option for combobox 1 the second combobox is disabled and a postback to my webservice never occurs.

How do you refresh a combo box from clicking on something from another Combobox (using Visual Basic).
I don't want to use a button for this as i know it works that way by using .Databind() on the other combobox.
In access it is so easy by using the click event on a combo box but visual studio does not seem to use it.
I would like to make a custom accordion, in which I have 2 panes, but where you couldn't open the second one until you clicked a validation button in the first one that would open the second...
I tried to just make a button that would hide the first pane but I cant get to make it work.

View 4 RepliesI need to use window combobox in asp.net c#
how can i use effectively.
I have a user control is shown through a SimpleModal popup (JQuery), this user control gets some data from database and displays them (the details of a record).
The problem is that this user control makes a round-trip to gets the data every PostBack for the parent page even it's hidden.
I wonder if I could make it gets its data only if the popup is appeared.
I tried to put it inside a Panel with false for Visible property and change it to true when I open the popup, but it stil call Page_Load which gets the data from database!

ada = new OdbcDataAdapter(cmd);
ada.Fill(data1);

View 1 Replieshow can i get valuefield from a combobox?
View 3 RepliesI have a comboBox within a grid. Basically to get it I have to use findcontrol. I am thinking of another option however. Within the init method I was planning on getting the value and storing it to a private static field:
private static RadComboBox theComboBox
Is it unwise to be storing a relatively complex object like this in a static field?
I was trying to use CssClass="WindowsStyle" with the following CSS. Its working fine if WindowsXP theme is selected but when the theme is changed it looks odd (different from other controls).
I wish to have the ComboBox similar to the style used by other controls. Please give me the solution for this issue.
I understand the issue is with the button(background-image: url(../images/windows-arrow.gif);) but what could be the alternate solution?CSS used
