Web Forms :: Populate Textbox Using SQL Database Query / Depending On A Dropdown List Selection

Apr 8, 2010

I would like to alter the query that is run, depending on the selection made by the user in a drop down list on the same page. Would this best be done using a partial page update (AJAX)? Ideally it would be great to have the textbox result change quickly once the drop-down list value has changed, without a full page postback. I would like to change the SQL query to a completely different query if the user selects an option different to the default (page_load value) in the drop-down list. I would then like the newly retrieved result to be displayed in the textbox as before.

My current VB function looks like this:

Forms Data Controls :: Populate A Datagrid On Selection From A Drop Down List?

Mar 17, 2011

This is my first post as a newbie to asp.net.

I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.

What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.

So far my edit page has a datagrid with the following code:

Templates - Populate List Items In Dropdown List From Placeholder?

Feb 24, 2010

I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:

<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>

This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:

<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>

I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view.

Forms Data Controls :: Populate Dropdown List With Special Character

Nov 1, 2010

Using a gridView to read some data from a SQL database. The user can select a record in the gridview. On the SelectedIndexChanged property I populate this to a couple of text boxes & drop down list; txtCountry,ddlProvince,ddlCity.

I have special characters in France ( accent marks) and when I populate it to the drop down list it fails giving out the error message "SelectedValue which is invalid because it does not exist in the list of items".

Example of items that I try to populate are as follows. ( separated by commas) ÎLE-DE-FRANCE , PROVENCE-ALPES-CÔTE D'AZUR , RHÔNE-ALPES, DRÔME,ISÈRE ........ When I looked in the drop down lists for Province and Cities I see those Provinces there in the item list. When I debug line by line the word ÎLE-DE-FRANCE comes out like LE-DE-FRANCE which is not there in the drop down list. Got to know the Î is typed by pressing down ALT+206 and lloks like this is what is coming in at the start of the string above.
