AJAX :: How To Clear A Combobox
May 11, 2010
I have been trying to figure out how to Clear out the contents of a combobox; both the dropdown list and the textbox. Currently I have
combobox1.Items.Clear()
combobox1.ClearSelection()
this is clearing out the listbox, but if something was in the Textbox it remains. If I add
Combobox.Text=""
then I get "Combobox has a SelectedValue which is invalid because it does not exist in the list of items."
I've tried several other combinations, none of which worked. how to clear out textbox portion of the combobox?

When the WebPage loads i would like for the Text to be cleared in Ajax ComboBox and/or DropDownList. However Setting the text to nothing or null doesn't seem to work. So I did some searching and found this...
[Code]....
Is there another way to clear the text other then adding a null item to the list? I don't really want the user to have a selection of "null", this seems like a hack job.

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.

Is there a way to programmatically select the entire string of the selected item in the AJAX Combobox?What I'm trying to do is bascially on a State/City selection.
1. User selects a State from the first combobox. This triggers the City combobox to be populated. The item(0) is "Select One:".
2. I want the entire "Select One:" to be hightlight as if the user had used their mouse and highlighted all the text.
The reason for this that I'd like the user to be able to start typing the city without needing to clear out the "Select One:" manually.

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 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

I'm getting an error in all browsers with the ComboBox that in IE causes the user to not be able to enter data into any other field on the form. In Firefox it just throws an error but doesn't cause any problems.
The error is this:this.ajax__combobox_prototypes[i]._popupBehavior is null

What is the most reliable way to get the current user input from a ComboBox? I've noticed that SelectedItem.Text, SelectedValue, and Text all contain the wrong result when the user deletes everything in the box and then immediately does something to cause a postback without clicking outside the box first (e.g. the user presses Backspace to delete the current contents and then presses a Submit button without clicking on anything else in the form first).

Anyone else have a problem with setting ListItemHoverCssClass of the ComboBox?
When using firebug it seems that it sets the class attribute of the li elements to "undefined" therefore is this a bug?

The code below when using a traditional ASP.NET DropDownList works perfectly. If a value is not picked (default value still displaying), then the range validator displays the problem. However when I use this same code with an AJAX ComboBox, the RangeValidator
returns false every time, and the message is always displayed. Take a look:
[Code]....
So every time I press a button to postback, the "** Item is required**" message is displayed. Again, this works just fine with a regular ASP.NET DDL, just not with the ComboBox from the toolkit. I can get a RequiredFieldValidator working with the ComboBox, but I like the post selection behavior of a RangeValidator better.

I am using a combobox.
I'm retrieving the data from database to fill the combobox. The name of the combobox is kategorilist. I want to set a string value to datavaluefield of the combobox. Also I'm using datalist with paging in this page. Datalist is binding with the selected value of the combox everytime.
Like this;
li.Value = "urunlist.aspx?ktid=" + dr["KategoriID"] + "&Sinif=" + sinifsa.ToString();
But it doesn't work. It worked with html <select> tag but ajax combobox doesn't accept this value.
Here is my code:
private void KategoriAdlariniGetir(int sinifsa)
{
DataSet ds = new DataSet();
SqlConnection con = new SqlConnection(cnnstr);
[Code]....
