Setting SelectedValue for ComboBox

In our asp.net web application we load the dropdown list boxes in the page load.  We than set the SelectedValue of each dropdown list box to an object from session.  We have event handlers for many of the SelectedIndexChanged events of the drop down lists boxes, but these do not get executed when we set the selected value programmatically.

Someone else mentioned this is by design, and only when a user manually changes the drop down list selected index, will the event get raised.

I would think this is a common scenario of wanting the selectedindexchanged event handled when setting the selectedvalue/selectedindex/listitem's selected property, of a DropDownList.  What is the suggested way to handle this?  Is there a significant drawback of creating a custom control inherited from DropDownList that has the functionality of raising this event when changing the SelectedIndex or SelectedValue?

DataBound ComboBox bound to DataTable of 2 columns with 1000 items (ZIP codes) is too slow when current selection is changed via SelectedValue. It tooks even 300ms on my i3 4GB W7 64bit.
In case of form with 10 combos on detail UI becames unusable in master/detail scenario.

If I implemented some FindRow method and current item is selected via SelectedIndex it works fine (at least it tooks 10-times less time).

Every possible change events are blocked during call of SelectedValues.

Any ideas how to correct this issue?

Thanks in advance.

Hello,

I ever thought that I can set a default localization if the users one (which is set in the browser) isn't available.

I've implemented my localresource files for localization. The start.aspx.resx contains all texts and elements for German use and the start.aspx.en.resx for English users. When I switch the language in the browser settings from German to English everything works fine and the english text is displayed. But when I switch to an other language which is not German or English, it takes defaulty the german resource files.

I've set

UICulture="auto:en-US" Culture="auto:en-US"

as well, but it didn't assume the .en resource file automatically. (For example when I enter the website and switch the browser language to French or Italian it should take the english resource files.)

Thanks and regards,
Chris 

Hi! I want to display a crystal report in my vb.net application. Suppose I have tables named student details, student marks, student address, etc... Now if I want to display all these details (fields of all tables) in one crystal report (with page breaks if necessary) then how will I achieve it. I will be providing a combo box in my application that contains list of student names. How can I link this combo box with the cystal report to dynamically display report for different student on selected index change of combo box? Help me friends. An example would be appreciable.

This month Paul DiLascia codes some Microsoft Office-style dialog box features.

The last time I wrote this column (March 2006), I shared an application that allows you to update all the Microsoft® Word documents in a folder and its subfolders. Each time the application finds a document in the specified path, it updates the document properties to match those you specified in the application.
