I've been trying to replace my dropdownlists with ajax ComboBoxes so i can apply css in ie.
I can't seem to apply any css to the items in the dropdownlist. Here is my css:[Code]....
I've tried putting font styles in every class but it does nothing. The font in the actual text bar is styled correctly.
Also i've noticed the dropdownlist doesn't display all the items in it. Only the top 2.
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

View 6 RepliesI'm trying to use two cascading dropdownlists with the same values -- one shows a code, and the other a description. They are sorted alphabetically, so they have the same values, but not the same index. Both are generating correctly. What I am trying to do is set the abbreviation when the description changes (and vice versa).If I use this javascript, it changes on the web page, but I get a null value returned to the form handler. If I comment out the CascadingDropDown control and load the TrickAbbrev from a database it all works.

I have a web app with several groups of cascading dropdownlists. All the cascading dropdownlists work as designed, but now the app is in the live enviroment with multiple users they are getting error 500 messages returned in some of the dropdownlists. Just wondered if there is a set amount of time to populate between selections? As these users are sometimes waiting tens of mins betwen selecting the values.On some of the dropdowns i'm pasing a date to the method using session variable whether this could be the issue? an example of one of the methods is below:

Imagine I'm developing a webform with two dropdownlists and a submit button. The second dropdownlist depends on the choice in the first, and both are loaded dynamically using webmethods being called with javascript in de ASPX page (ajax). When I submit the form to the server, to save the data, I can't get the value of those dropdownlists. I think it is because with client AJAX no viewstate data is being generated. I need to send the data to the server and save the webform data, and identify wich data is on each webcontrol.

View 3 RepliesI'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.
Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.
I need to replace <span> entries in a string to legacy html code because it's going to be used in a report for Crystal Reports. <b> works with Crystal, but the<span>'s do not.

<b>%THIS CAN BE ANY TEXT%</b>.

View 4 RepliesI have some cascading dropdownlists using the ajax toolkit I have a set up datatables in an xsd file. Then use these in a webservice to populate all the fields ... this all works great but now i need to pass an additional paramter to the first dropdownlist ( a date) but don't know how to do this? The method is below...

The other code is:

The first change would be to the tableadapter to add a param to the code i.e

but how do i get the calldate param to the webservice method... i tried a session variable but it comes up with session is null ? Is there another better way?
I am using the ajax toolkit calendar extender control with the asp.net button for the postback event. the functionality is after selecting the date, clicking on the submit button will call the button event. now I need to obtain the same thing without clicking the button and on the date selection. ie, on selecting or closing the calendar control the postback event has to fire. how too obtain this? calendar and the button are placed in the user control.
View 8 RepliesI have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?
i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?

I'm using a code I got from CodeProject [URL] about a validator that can monitor 3 form controls. I pasted it to my site, changed it to suite my parameters but seem to encounter a situation that can't satisfy my desire: Instead of making sure that all the 3 DropDownLists are filled without their default value, the validator cares only if at least one has been filled, and if so, he can call it a day. look at this code at tell me what am I doing wrong?

I have to generate multiple dropdownlists on clientclick. That is new dropdownlists on every client click.
I placed a button and wrote code on click event. protected void addReq1_Click(object sender, ImageClickEventArgs e)
{
DropDownList oDdl = new DropDownList();
oDdl.ID = "ddlReq" + (++i).ToString();
oDdl.DataSourceID = "DSUsers";
oDdl.DataTextField = "UName";
oDdl.DataValueField = "UName";
HtmlTableCell tc0 = new HtmlTableCell();
HtmlTableCell tc1 = new HtmlTableCell();
HtmlTableCell tc2 = new HtmlTableCell();
HtmlTableCell tc3 = new HtmlTableCell();
tc2.Controls.Add(oDdl);
HtmlTableRow tr = new HtmlTableRow();
tr.Cells.Add(tc0);
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
tr.Cells.Add(tc3);
search2.Rows.Add(tr);
}
Here "DSUsers" is SqlDataSource. "i" is static variable. "serarch2" is html table with runat server tag The problem is only one control is getting rendred, after that on every additional click same DropDownList is getting replaced. No new DropDownList is added to the page.
I have created a label and a dropdownlist. The label has the dropdownlist as associated id.If I click on the label and then uses the mouse up or down the dropdownlist creates a postback for each click. This is quite anoying and doesn't happen if you click on the dropdownlist and uses key-up or key-down, or if you uses another browser than IE.Is it possibel to fix this, so you can use key-up and key-down without causing a postback, and first on the enter-key creates the postback (as it does if you click on the dropdownlist and not label)?
View 2 RepliesI am trying to use two DropDownLists (Cities, Categories) in a PartialView that will be used in MasterPage, meaning they will be visble all the time.
I tried to load them in HomeCOntroller, but that didn't work. I got an Exception.
I read something about making a baseController that the other controllers will inherit from, I have tried that, kind of, but I guess i'm doing something wrong.
This is the only code I got today:
Masterpage

PartialView (SearchForm.ascx)

Two question:
Where and how to load the DropDownLists is the problem. I have tried to load it in the HomeController, but when go to another page then it says that the DDLs is empty and I get a Excecption. Why do I have to use two forms for the ActionMethod to trigger ?
