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 have added some combobox and texboxes in gridview dynamically to provide the data entry like operations.i have fetched and reset the value of these dynamically added controls on button click as ->
I inherited a site which I am in the middle of updating which has a DropDownList and a RangeValidator assigned to it. The data is bound to the dropdown on Page_Load. The values are retrieved from the database so the value property of each item is set to the unique ID of the item in the DB.
The RangeValidator looks something like:
<asp:rangevalidator id="ddRangeValidator" runat="server" ControlToValidate="ddMenu" ErrorMessage="Please select value in range" MinimumValue="1" MaximumValue="100000" Type="Integer">*</asp:rangevalidator>
I have a method which automatically populates this value in jQuery e.g.
$("#ddMenu").val("An Option");
This works, however, when I try to post the page the range validation fails. Then even if I manually select that value, or select another valid value it still won't validate. The only way to make it validate is to select non-valid value and then re-selecting a valid one.
Here is the data binding code:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load, Me.Load
If Not Page.IsPostBack Then Dim ds As New DataSet() Dim myDbObject As New myDbObject() ds = myDbObject.ToDataSet() // retrieves all objects from the database
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 am working on a ASP.NET app that supports user level cultures. Just about everything works, however, I am running into a problem with the RangeValidator. Here is the sample control set:
[Code]....
When a culture that uses "0,0" (pt-BR for example) attempts to load this page with the controls as shown, it bombs (Gives an ASP.NET debug page). If I either set MinimumValue="0" or add CultureInvariantValues="true" the page will load. The problem with this is that on several controls, the minimum value is actually 0.0001. When I use the CultureInvariant setting, that validator is telling me that the following values are invalid: ".031" and "1", no matter what culture I am using to view the page.
I understand the the CultureInvariantValues setting applies only to the values in the Min/Max settings on the validator, not on the data entered in the control that is being validated. But this does not explain why values that should be accepted as valid are being flagged as invalid.Our application currently runs in 20 different countries and is internally translated into 4 languages (based on user culture settings), with 3 more on the board for this year. I have googled this extensively, and while I have found some info on Currency and Date data types, the problems experienced are not the same.
I thought my issue was related to the Validators not working in UpdatePanels but that does not seem to be the case.
All validators fire when they should but, the error warning message clears when the updatepanel updates.
for example...
textbox1 range 1 to 23. dropdown1 updates the updatepanel. enter 99 error shows, but will disapear when I change value of dropdown1. textbox1 value still 99 so validator message should still show but it does not.
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 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 have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
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).
I need to fill Combox only after the page loaded. same like AutocompleteExtender. My Page have more than 10 ComboBox and it will be good for my project if only ComboBox can populated when use make setfocus. if there is something like AutoCompleteExtender for ComboBox?
