AJAX :: ComboBox And The HTML DOM's DefaultValue Property?
Dec 13, 2010
While debugging my Javascript, I've noticed that ComboBoxes always have an empty string as their defaultValue (as opposed to the actual original value). This is making it impossible to write even a semi-reliable client side script to check if a form has been filled out and warn the user if they attempt to navigate to another page or close the window.
i have 4 comboxes (com1, com2, com3,com4) and 4 tables (tab1, tab2, tab3, tab4)com1 and tab 1 have master table relationships i.e when in com1 the name is entered tab 1 shows the result of that entry. the same is for the rest comboxes and tables.
Now what i am trying to do is when an user clickes on com1 and types the name of the employee tab2 tab 3 and tab 4 should be hidden. if com2 is clicked tab1 and tab3, ta4 shoud be hidden.etc
Currenty i am using this code which i do not like. Is there any easy and short way to do hide an show.
this is the code i am using
<script type="text/javascript"> $("#com1").on('click', function () { $("#div1").fadeIn();
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.
it binding correctly(datasource dynamically binded) and it raises event too while changing index but it is not raising event when we manually clearing the combobox text..if currently combobox having text "ASP" then i manually select that entire text and using del key i am deleting but it is not raising event for me.. when i change index it automatically raising event...i need to raise event while combobox is empty...
I have an entitydatasoruce that is driving a gridview. I have a WHERE parameter that i want to include 2 default values (example Work_Area = 1 OR 2)But it seems I can not input this query when making a querystring within the expression editor
I have an SQL table with a smalldatetime column. The Default Value is set to (getdate()), as I want it to insert the date in which the record is inserted. Null values are not allowed.In my corresponding Table Adapter in Visual Studio 2010, when I select that column and view Properties, under DefaultValue it has <DBNull>. If I try to change this to GetDate(), it won't let me.What's the proper way to do this?I am getting the Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.error when I try to execute a Table Adapter query that simply tries to return all the rows.
I'm working with Linq and I'm using with ObjectDataSource that have SelectParameters tag for inserting default parameters to object.
How can I set <DefaultValue> for an array parameter ?? (i.e : object that have 2 parameters - string and array of int , I can set <DefaultValue> for the string but I don't know how to do it for array)
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.
I an expanding on the HotGridView control (http://msdn.microsoft.com/en-us/magazine/cc163612.aspx). During testing I noticed the "AutoGenerateCheckBoxColumn" behavior was returning true even if the user did not specify the a value in the markup but I expect it to return False if not value is supplied by the user - can anyone shed some light on why the AutoGenerateCheckBoxColumn is always true if not explicitly set to False in the markup?
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 want to create a dll Only for Ajax ComboBox. I mean I want when I add this dll in toolbax, I able to drag Ajax Combo Box control on web form.Ajax provided source code & JavaScript files for ComboBox but how I can Create a dll from this.
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).
