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.

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.
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.

The last time I wrote this column (March 2006), I shared an application that allows you to update all the MicrosoftÃÂ® 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.

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.

I want to have the background of my masterpage (the master page for all of my .aspx pages) have a sort of gradient. I imagine the only way I can do that is with an image. Or maybe even some other design, but I want to move away from the "solid color" background.
Is the easiest way to do this just to make an image and set that as the background? What image size should I make it, because some users could possibly have the normal aspect ratio, or maybe a widescreen? What should I make it like so that it looks good on all computers?
Thanks in advance. :)
I have a ListBox control showing 10 rows. I have 30 rows total in the listbox. How do I programmatically adjust the scroll to show the last ten rows?
Some sources have suggested that I set the SelectedItem. But I am already making selections (myListBox.Items.Selected = true, myListBox.Items.Selected = true, etc); the listbox scroll is positioned on Item not the first selected item. I have also tried setting myListBox.SelectedItem in addition to the multiple selection just mentioned but that does not have any affect either.
I am using VS 2010 Professional with SQL Server 2008 Developer. I right click on the App_Data folder in solution explorer and add an existing item, then navigate to the correct database. However, I receive a pop up that Access is Denied. How do I fix this?
I'm in the process of deserializing a JSON object into an Entity Framework object. The property names in the JSON do not match up totally with the property names in the Entity Framework Objects. What I'd like to do is set "Name=" on the "DataContractAttribute" for the table and the "DataMemberAttribute" for the properties in the Designer.cs file. I tried setting these in the Designer.cs file manually just to see if it would work - which it did (using JSON.Net) but of course when I went into the .edmx designer I lost all my changes. Is there a way to do this?
Thanks in advance
We have a SharePoint farm consisting of 5 web applications. These are tied together through branding and a custom sitemapprovider which present the farm as a single environment to end users. Our visually disabled users however have to enable
the accessibility mode for each web application. Which is a nuisance, ideally they would only have to enable once for the complete farm. Does anybody have a solution for this problem.
