On running the application, i see the ComboBox but none of the list items are visible. Clicking on the dropdown button does not show anything also. Accessing the SelectedItem property shows that the first item is selected.
How can I achieve hover effect for the ajaxtoolkit combobox. I just need an outline for the entire combo i.e. outline for combo-textbox and combo-button when hovering over the combobox otherwise it should return to the normal outline color.
I could only get the hovering effect for combo-textbox alone and that too an outline creates at outer of the existing combo-textbox outline.
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 combobox & button in my webpage, if i select a value from the combobox, then i click the button the page is refreshing, combobox value is changing.For Example Combobox value: 1, 2, 3, 4 .....If i selected 2 then i press the button, webpage is refreshing, combobox values is display from: 1, 2, 3, 4....Combobox should display 2Why combobox is displaying a selected value when i press the button.
Table Name: user
Name username
Raja 1 Ravi 2 Ram 3 kumar 4 ...,
Button click event code
cmd1 = new OdbcCommand("Select name from users where username = '" + combobox1.Items[combobox1.SelectedIndex].Text + "' ", dbcon); dr1 = cmd1.ExecuteReader();
[code]...
The Above code is working, but if i select the value 2 from the combobox, then i press the button textbox should display ravi, but textbox is displaying Raja, and also combobox also refreshing, combobox is not displaying 1 instead of 2.
I need to manipulate the combobox (from AJAX3.0) in ASP.NET through javascript. The webpage is simple. There is one dropdownlist and one combobox. When the selection of the dropdownlist changes, I need to change the combobox accordingly, may remove a few items or add new items. Right now, I know how to add items into combobox using javascript from the topic:[URL] And I need to how to remove one of the item from the combobox according to a text or just clear all items.
I've a webform that has a formview in insertmode that among others has a combobox with a datasource. The problem is that user needs to have a way to add new items to combobox directly rather than having to go to mainteinance webform that deals with the info related with the table that feeds combobox. So I thought that I should have an update panel and put the combobox in there together with a button to open a popup window to add the new record, close when done and update combobox with newly added item.
In theory that's what I want. What I require are examples of how to do that in the best way. I thought first of using javascript but how do I know when the popup window was closed? how to trigger update panel?
I wonder how to validate if a inserted item in a Combobox exists in a database during postback? If the item.text exists, a errormessage should notify the user that the item already exists in the database. If the item does not exists in the database a inserting should be done.
Should i use the customvalidator and create a servervalidationfunction that searches my databasetable for the item name?
Should i validate inside one of the two ComboBox control events, ItemInserting and ItemInserted?
After validating the existence i would like to validate if the inserting to the database was successfull.
I have some value in variable string var="some text"; i have bind the combobox with list but during loadoing of form i want var to be displayed in editable portion of Combobox...
I've just downloaded the latest Ajax libraries. I have a web site with dozens of ComboBoxes that worked fine until intalling the new libraries. Now the combobox dropdown lists, show behind the other ComboBoxes on the page.There was also an issue where the dropdown lists didn't display in the proper position, the div they are contained in is set to Position:Relative, I had to add position:absolute ! important along with coordinates of coarse to the css .WindowsStyle ul
I am designing an user control in ASCX similar to which is shown in the link below [URL] I am using textbox with Div around and image for arrow and a listbox group control for multiselect option and wrote a javascripts to show and hide the listbox when onclick of image arrow. I could achieve everything except when I click on outside the list is not disappearing
I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
Is it possible to select values from a List, where the items contain in a different list aswell?for example;
[Code]....
What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
Buenos nachos, to be brief, my question is: is it possible to allow users to add new items to a combobox at runtime without having the autopostback property set to true? I understand it needs to postback if a new item is added, but I do not want the box to postback if the user simply selects a different value!
The tag I currently have is below. Without having the autopostback="true", the comboxbox doesn't allow the user to add new items to the box >_<' Any thoughts?
I've been trying to figure out for a long time now how to create an interface that can allows users to input several rows of data and pass those entries into an SQL server database all in one shot. I could not get any better ideas so I came up with this (see picture below).
What I envisioned is that the user enters values in the textboxes and hits the "add to list" button. The values are then populated in the list box below with the heading "exhibits lists" and when the add exhibit button is pressed, all values from the list box are passed into the database.
Well, I'm left wondering again if it would be possible to tie these values from the textboxes to the list box and whether I'd be able to pass them into the database.
how to go about it otherwise I'd be glad if you could recommend a better way for me to handle the situation otherwise I'd have to resolve to data entry one at a time.
