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:

MVC :: Loaded A Cascading Drop Down List Using Jquery. However My Selection Does Not Update?

Oct 6, 2010

I have 2 dropdownlists, the second (department) cascades from the first (division). I use a jquery script to update the second drop down list. When the user clicks submit, the underlying model is updated, apart from the new value for department. 2 ideas I have for fixing this are; a) Generate a postback. Prefer not to do this because of bad user experience. b) With a JQuery change event, make a call to server side and set a ViewData variable that I can use to update the field in the model later.

However there must be a better way. This is the view;

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/AdminAccounts.master"

Get Drop Down Selection From GridView On Button Press?

May 21, 2010

I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView.

What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?

C# - AJAX Update Panel Action Button Click On Drop Down Selection

Aug 11, 2010

I have the following scenarion. I have a range of drop down menus where a clietn can select. The code below is wrapped in an update panel but without this, the button click fires a method to retrieve the number of products. So for example, an item is selected from ddlCategory, the btnValidate is clicked and the label returns the number of products within that category.I have the following code for an update panel - I'm just not sure how to implement if effectively.

<asp:UpdatePanel ID="UpdatePanel1" runat="Server">
<ContentTemplate>
<asp:Label ID="lblSearchResultsStatus" runat="server" Text="Number of results found: "></asp:Label>
<asp:Label ID="lblSearchResults1" runat="server" Text=""></asp:Label>
<br />
<br />
<asp:Button ID="btnValidate" runat="server" Text="Validate Search"
OnClick="btnValidate_Click" Width="120px" />
</ContentTemplate>
</asp:UpdatePanel>

How do I go about wiring the update panel so that when a drop down list item is selected, the buttong is effectively clicked?

Web Forms :: List Box Multiple Selection Not Happening?

Nov 12, 2010

I have two Listboxes side by side. First Listbox lists all employee. I have a button to move selected employee from Listbox 1 to Listbox 2. If i select multiple employee from ListBox 1 and click on a button to move to selected employee to ListBox 2, then only alternate selection is moved.

For example.

If ListBox 1 have employee listed as :

1. John
2. Micheal
3. Bryan

After moving to ListBox 2. It shows:

1. John
2. Bryan

My Code is:

protected void btnAdd_Click(object sender, EventArgs e)
{
for (int LItem = 0; LItem < this.ListBox1.Items.Count; LItem++)
{
if (this.ListBox1.Items[LItem].Selected)
{
this.ListBox1.Items[LItem].Selected = false;
this.ListBox2.Items.Add(this.ListBox1.Items[LItem]);
this.ListBox1.Items.Remove(this.ListBox1.Items[LItem]);
}
