I have an Ajax Toolkit combo box in DropDownStyle Mode. The DropDownStyle should prevent the user from entering values that are not in the list of items of the combo box. The problem is, if the user paste some text (right-click --> past OR ctr + V) in the combo box, it will work, event if the pasted text is not the list of items. Is there a way I can prevent this?

I have added a combobox to my page. Listview is updated based on selection from combobox. It is working great except it does not fire when Enter is pressed. User has to click on option from dropdown or has to press tab key to have Listview to populate. I want the user to be able type use arrow key to select option and then press the enter key for event to fire.
Using .net 3.5 and c#

there a way to change the width of the combobox control dropdown list? The problem is that because of the entries in it width of the combobox' dropdownlist exceeds the width of the screen resolution itself.So, is there a way to set a fixed width or any other better solution?

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 am trying to get two cascading dropdownlist to work but cannot get either to populate. How do I de-bug this? I'm not getting any errors, just blank dropdowns.
I've been trying to fill in webservice from SQL Server. But in-case this was the problem. I found an example on this site to fill with test values, but this still does not work. Since I cannot even get first to populate, to simplify I'm just giving code for first dropdown and its function(s)

I have built a dataset named Transaction_Time.I called it on Page_Load
Transaction_Time tranTme = new Transaction_Time();
put it in the session.
Session["Transaction"] = tranTme;
Then I call that session and cast to dataset.
DataSet dstTranTime = (DataSet)Session["Transaction"];
I got the following error.Unable to cast object of type 'Transaction_Time' to type 'System.Data.DataSet'.

I am not sure if I have found the right forum for this one.
the problem is:
I have a .licx file in my rootfolder.
I am getting the error:
Error 53 Unable to resolve type ' <add type="TabStrip" version="7.0" />' C:inetpubwwwrootCrop_ApplicationCrop_Applicationeo_web.licx 7 Crop_Application
,which I get for all the types that are in the xml file(i just gave one of them).
A friend told me that I have to add the type .licx in the MIME type in the IIS .
The problem is that I find the MIME type, I add the extension type .licx but I do not know the MIME type for .licx
