I have a combobox (DropDownList) control in my aspx project, linked to a datasource. I would like to show more than one field on the dataTextField (like in MS-Access). It's possible? How can I do it?
View 1 RepliesI 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 want to put validation on a combobox to ensure user selects/enters a value. I've tried using a the standard required field validator which doesn't work. So I would like to do the validation using javascript/jquery.
Not sure how to approach. When I look at how the combo box is rendered, it appears as a unordered html list. There is also a hidden field but this always seems to be set to 0.So is it possible to do this validation client side. I've read so many posts about this but I havn't got an answer yet.
I am using the combo box for my project and I am having some odd behaviour from combobox...
i am using this combobox inside a formview control...once i click on combobox it is showing the list items at the bottom of formview not next to combobox control...I think it is taking the top and left values from formview offset.
ajaxcontrol toolkit combobox control, a picture is worth than a lot of words so here is the picif you are not able to view then here is the link

the problem is the items text in the combox box is having a square beneath at the second character which is hindering the visibility of the list. but the square is not appearing in the text area.
I am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:
[Code]....
But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.
I am trying to included a rating control in a composite control that renders many different type of controls. I render the controls by overriding the rendercontents so that I can control the layout of the controls. When I try to add the rating control to the output i get a Page cannot be null error. Can someone provide me with the proper way to render a rating control from a composite control and be able to control the layout of the child controls.
View 3 RepliesI'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 an implementation of a textbox which inherits from the TextBox control. It currently has some features built in to validate text by some JavaScript that is injected when the control is created. I want to modify this so that the control uses the ASP.NET validation controls (eg. RequiredFieldValidator) instead. Is this possible? Is there a place in the lifecycle of the control where I can programmatically create a BaseValidator control and add it to the form? I want to implement this in my textbox control, rather than each specific page that the textbox is on.
View 4 RepliesI 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.

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 just downloaded the latest ajax control toolkit and was trying to use ComboBox (as described on the samples page). However, I can't find it (tried to do reflection on the assembly as well).So is the ComboBox still in ajax control toolkit or it is removed or renamed etc?

I have just started with ASP.NET.
I like the idea of using Include files so that I can create various versions of individual parts of a site and decide in code which to display. I used:
<%Response.WriteFile("contentcontent.aspx")%>
to include a content.aspx file within my default.aspx page.
I would like to include a Left.aspx, Main.aspx and Right.aspx file inside the content.aspx file. I tried using the reponse.writefile function but noticed when I debug the website that the text "reponse.writefile..." displays instead of the code contained within the referenced file(s).
Can this not be done?
I have 2 tables, call them stock and visit. Stock contains a list of standard products (code and description columns). Visit contains a list of products used during a visit (product description column amongst others). When a user adds a product to the visit table they can either select a standard product from the list or select a product code and amend the description, e.g. they could select "paint" and change the description to "blue paint". The new description will only be relevant in the Visit table. This all works fine.
I have an editable gridview which lists the products used during a visit. There is an Ajax control toolkit combo box in the EditItemTemplate which allows the user to select a different product. If the product exists in the Stock list then everything works
fine. If the user amended the description (e.g. changed "paint" to "blue paint" when they added the product to the Visit table I get the following error.
'ProductDescription' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
I presume this is because the amended description won't exist in the standard list of products. How do I add the amended description to the combo box list? I've tried using the RowEditing event but can't reference the combo box in the EditItemTemplate.I think what I want is something along the lines of [Code]....

I am trying to render control(ComboBox) programmatically, and i am getting error that tell me that i have to add ScriptManager to the page.
But, i did that, and still its not working:
[Code]....
And the render control html is:
protected override void Render( System.Web.UI.HtmlTextWriter writer )
I have a ajax combobox in my page, when i try to select an item from it i can select by typing in text and its selectedindexchanged event fires, but when that event is complete and when i try to select another item from the combobox it produces the following error:
could not complete operation due to error 800a025e,and an alert asks me if i want to debug it.If I press yes then i get this page:
// Name: AjaxControlToolkit.ComboBox.ComboBox.debug.js
// Assembly: AjaxControlToolkit
// Version: 3.0.30930.28736
// FileVersion: 3.0.30930.0

htmlfile: Could not complete the operation due to error 800a025e.
_setTextSelectionRange: function(textBox, selectionStart, selectionEnd) {
// set the selection range on the text box[code]....
The Weird thing about this is that the error does not occur on the development machine but only on the server.
I have problems with optimizing AJAX Control Toolkit. The specific problem is that 4800 records take about 30 seconds to bind in Internet Explorer (only 2 seconds in Opera & Firefox). I've tried anything, but I still can't improve the load time in IE.I've already enabled compression and caching, I'm using ToolkitScriptManager instead of ScriptManager. I've tried setting LoadScriptsBeforeUI and EnablePartialRendering to false, but it still doesn't help.
This is the query I use for binding.

I have a display problem when I try to use a ajax combobox inside a tab control: when my tab control loads on the page where the combobox is, everything works fine; however, if it loads on a another page, the you change to the page which contains the combobox, the right button (which opens the list of the combobox) isn't displayed at all.
View 1 RepliesAll I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:
<!--#include file="EditProject.ascx"-->
I tried this but no luck!
Parser Error Message:
There can be only one 'control' directive.

I currently have an Instance of the ASP.net ajax control toolkit combo box residing in a field set with a style of position:releative applied. The control also sits in a very plain table.
There are two problems with the display of the list:
The list does not sit flush with the text box. In I.E. 7 (which is the majority of my target audience, intranet where IE7 is the company standard) the list display about 10px below the fieldset, which is what the bottom margin of the fieldset is set to. In FF 2.0 the list sits sinificantly lower and off-set to the right.
Below the filed set there is more content in a div, also with a style of position:relative applied. The list from the combo box displays behind the content of this div, which is obviously an issue.
Removing position: releative from the fieldset resolves the display issue of the combo box, but results in other unwanted display side effects.
I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
I have grid view control that includes a dropdown control in a template field.I wish to execute some code when the value is changed in the dropdown list. Can't figure out how to capture this event though?
