Posted By:      Posted Date: September 22, 2010    Points: 0   Category :Windows Application
 

I could'nt find any pages that populate Combo box values faster.........in C#

 

This code snippet in C# pulls data from a DataBase : Modal, Table : Tbl_Area using a stored procedure : SelectDistinctStates_sp

SelectDistinctStates_sp contains :

 

CREATE   PROCEDURE SelectDistinctStates_sp 

AS

SELECT AreaName as AreaName FROM Tbl_Area

GO

How to dynamically populate a ComboBox through client-side Javascript?

  

I'm using the ComboBox control from the May 2009 release of the ASP.NET Ajax Control Toolkit.

I'd like to try and populate this ComboBox's list of options dynamically from the client-side Javascript (because I'm retrieving the data from the server based on the user's selection in another drop-down box).  Can anyone suggest how to accomplish this?  I tried this:

 

                var teacherComboBox = document.getElementById("ctl00_ContentPlaceHolder1_TeacherComboBox_OptionList");
                teacherComboBox.innerHTML = "";
                
                for (var i = 0 ; i < result.length ; i++) {
                    var listitem = document.createElement("li");
                    listitem.innerHTML = result[i];
                    teacherComboBox.appendChild(listitem);
                }


 

And it didn't work.  The ComboBox just ended up with just one item (the first one) in the list, instead of all of them.

Any help appreciated.

Thanks.


How to populate a ComboBox from a list

  

I have two basic lists (Alist, and Blist).

One field from Alist is a textfiled of selection type (ComboBox). I want to fill this combo with the content of Blist.

When I create a field I can chose to populate the ComboBox from an static list, but I don't know how to bind to a SharePoint List.

It is possible to do in easy way?

Thanks for your time!

Using a trigger or anything else to populate two tables

  

Hi! I'm creating an application that's supposed to first add a record to table1, and then get the ID from that record to use when adding a record to table2, to be able to associate these two records with eachother.

The user gets to type in some values that goes to table1, and some values that goes to table2, but before the insert statement for table2 is executed i need the ID from the recently added record in table1. Some dude told me to use a trigger for the autopopulate purpose, but does that really work when i also need to save some values that's user input, and when those values doesn't get saved in table1?

Are there any other way to do this or can i send values to a trigger? I'm new to triggers and stored procedures, i don't have any particular knowledge of this, any help is appreciated!

Is it possible to populate property choices from a database?

  

I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices,  based off of that enum.  But I'd like it to pull records from a database and populate the list of choices for the property from a database.  This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.

Thanks,

Russ

ActiveX and Visual Basic: Enhance the Display of Long Text Strings in a Combobox or Listbox

  

The combobox and listbox controls in Visual Basic have no built-in support for displaying text strings that are too long to fit in the visible area of either control. This article describes several techniques to improve the readability of long strings in each control. The first technique uses tooltips to display a combobox or listbox item. The other techniques, which use various Windows APIs, include adding a horizontal scrollbar for a listbox and determining the necessary width of the longest string given the font attributes of the text. The required steps are described for both comboboxes and listboxes.

Trying to get Roles to populate a checkboxlist based on tutorial and having issues.

  

I have been using the following tutorial and had to convert the code to C# for my project, now i cant get the code to work, im getting red line under the word "in" in the UpdateRolesFromList,
i tried to add a datasource on page load for the checkboxlist like so RoleList.DataSource = PopulateRoleList(User.Identity.Name.ToString());

        {
            
        }

            roleNames = Roles.GetAllRoles();
            foreach (string roleName_loopVariable in roleNames)

Dynamically Populate a DVWP depending on selected item

  

Hello,

I am wanting to create a dashboard page with several data view web parts which dynamically populate depending on what item is selected in a separate web part (drop down form or just a list of links).  Can someone please point me to a tutorial or documentation on how to pass data between web parts or to a DVWP?  I have searched for a few hours and not been able to find anything useful.

Thanks,
