DDL Selected Value Which Is Invalid Because It Does Not Exist In List Of Items

Mar 15, 2016

I am attempting to load a page to edit previously saved info from a SQL2008R2 database. When a drop down index changes, it is supposed to load the existing data from a table. Most fields work OK, but drop down lists throw the error. The list is bound to a different database and table from the existing data that is to be edited (if that makes sense). So, when the data is called for editing, that comes from tableB. The drop down list is bound to a different data source, tableA. When the initial data entry was done, the item exists in the table, so I fail to see why this error is thrown. There are many dealing with this symptom, and I have tried many proposed solutions with no good result. Here's the code that retrieves the data and throws the error...

ASPX code:

Code:
Product Brand Name: <asp:DropDownList ID="product" runat="server" AppendDataBoundItems="True" DataSourceID="SqlDataSource19" DataTextField="Brandname" DataValueField="Brandname" AutoPostBack="true"><asp:ListItem> </asp:ListItem></asp:DropDownList>  

The SQLDataSource19 is from tableA.
VB:

Protected Sub DropDownList6_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList6.SelectedIndexChanged
Dim conn As New SqlConnection("Data Source=server;Initial Catalog=database;User ID=user;Password=password")
Dim cmd As New SqlCommand
Dim reader As SqlDataReader

[Code] ....

The data is bring called from tableB. The error is getting thrown on the product.selectedvalue line..I think I understand the problem, but I am not sure how to resolve it.

Web Forms :: Web Control Calendar Load With Selected Month Appearing?

Jul 29, 2010

Using vb.net/asp.net 2005.

I have 2 web control calendars on a web page where I allow the user to select a startDate (WebControlStartDate) and endDate WebControlEndDate. Then the user can click the "Refresh" button to update the report that is displayed.

I am able to successfully store both the startDate and endDate value in a session variable and after the user clicks the Refresh button then both the StartDate and EndDates are chosend on the start and EndDate calendars.

However, both the StartDate and EndDate calendars are defaulting to the current month, meaning even if I select a previous month after refresh I will have to click back to a previous month in order to see the selected Day. After clicking refresh I want both month displays on the web control calendars to disply the months that were selected.

To summarize: each calendar is selecting the correct dates I just want the pageLoad to display each selected Month after the user clicks the Refresh button.

But if I change my condition to Not selected, the string does build, with every item in the list. So the Sub is reached, the items and their text and values are seen, but user selection of items doesn't work. What am I missing?

Web Forms :: Clicking The Label Of A Dropdown List - Resets The Selected Value To The First Item In The List?

Feb 17, 2010

Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.

In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.

How to prevent this one. It should be on PRIMARY Only.

<p>
<tr> <td ><asp:Label ID="lblContactType" Font-Bold="true" Text="Contract Type: *" ForeColor= "red" runat="server" AssociatedControlID="ddlContactType"></asp:Label> </td> <td > <asp:DropDownList runat="server" ID="ddlContactType" DataSourceID="SqlDataSource2" AppendDataBoundItems="true"
DataTextField="TYPE" DataValueField="ID" SelectedValue='<%# Bind("CONTACT_TYPE_ID") %>'>
<asp:ListItem Text="Select One" Value="0" Selected="True"></asp:ListItem>.......

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.
