I have a DropDownList populated with a SQL Stored Procedure. On the page, there is also a button that when pressed, processes the contents of the dropdownlist. I would then like the dropdownlist to automatically remove the selection, and if there is nothing left in the dropdownlist, I would also like the button to be disabled.

However, I would like "Please Select Name" to be the first item in dropdown list.

I'm attempting to load DropDownLists from the C# codebehind as the FormView switches modes to Edit and displays the EditItemTemplate. I present the data in a FormView ItemTemplate using text boxes. When the user selects Edit, I have been attempting to load the EditItemTemplate dropdownlists by creating a dataset and binding it to the control, without success.
I've successfully loaded them in previous projects from within the .aspx code using <asp:ListItem> and within the C# code behind using Control.Items.Add(new ListItem), which are essentially the same thing of course . This project is different in that I want to get the data from a stored procedure on a MSSQL server.
In my latest attempt, I can see the data in the datasets. I'm getting "Error connecting to database.'eitRace' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value"
I include the code below. If someone could point me to an example I would be greatful. There has to be an elegant way of accomplishing this.

I want to have a dropdownlist in the footer row of a gridview. The dropdownlist must be populated with an stored procedure that receives a parameter and has a select. Is that posible?? I think yes but I having problems with the parameters.

The exception says incorrect sintax... but I've changed the procedure for something very simple to solve the problem like select 'hello' or select 1, 'hello' and I'm getting the same problem...
Girdview has dropdownlist TemplateField called ddlSate, how to bind state field value in sql table to selected value of ddlState dropdownlist control? For example the sql table has AL value for state field, (Note by default ddlState lists all states options with sqldatasource), how AL is selected in ddlState when binding to ddlState?
Secondly, when user selects different state like GA, how below update stored precedure works? that means how to find ddl selected value in update procedure as shown below question mark line:
Here is part code:
<asp:GridView ID="gvOrder" runat="server" DataSourceID="ods1" AutoGenerateColumns="False"
style="margin-top: 11px" CssClass="pnlOrdercss" ScrollBars="Both"
BorderColor="Black" BorderWidth="1px">

how to convert the Oracle Stored Procedure to sqlserver 2005 Stored Procedure
Initially, I have tried to use stored procedure. But I changed my mind and preferred to call sql query in codebase with command text. However, it stills tries to find initially-called stored procedure (which is neither called or exists).I think that it is related caching. But I tried it with different browsers it did not work.What might be the reason?

I have 2 dropdown lists on a WebForm. One of them is populated in the page's Page_Load event. This oneworks fine with the following code.
[Code]....
Then, after a value is selected from this list and a date is selected from a DateTime picker, then I click a button which is supposed to populate the 2nd dropdownlist. In the debugger in the button's click event I can see that the dataset is being populated with data, but then the list is never populated after the DataBind() method is run. Here is code from the button's click event.

DropDownList Not Being Populated
[Code]....
I have two drop down lists on my page. One (DropDownList A) has the values preset by me. The other (DropDownList B) has its values filled by a database query if a button is pressed. Each of them have AutoPostBack set to true. Each of them have corresponding onselectedindexchanged functions. DropDownList A works fine. When I change it, I want it to turn itself invisible. It does. DropwDownList B is not working. When I select something, it does the postback but the selected item is reset and the onselectedindexchanged function is never called. I feel like this is a problem I've solved in the past, but it's been 3 years since I programmed ASP.NET. All this is done in C# by the way.
View 12 Repliesi am currently working on a webform that has several dynamically populated dropdown lists. this works just fine, however, i have other web controls that require to have a postback..and at the time the page postsback, it reloads my dropdownlists, reseting whatever option i had chosen...
what can i do to resolve this?
Sample Code.
<asp:DropDownList ID="MediaTypeDDL" Width="306px" ToolTip="Select Media Type" runat="server"></asp:DropDownList>
<asp:DropDownList ID="MediaFormatDDL" Width="306px" ToolTip="Select Media Format" runat="server"> </asp:DropDownList
<asp:Button
ID="btnUpload"
runat="server"
OnClick="btnUpload_Click"
Text="Upload"
/><br
/>
protected void btnUpload_Click(object sender, EventArgs e)
{
String strMediaFormat = MediaFormatDDL.SelectedItem.ToString(); // Not seeing value here!
}
Item Selected in MediaTypeDDL determines values in MediaFormatDDL. I'm using Javascript to populate MediaFormatDDL. This is working. I now select the item I want from MediaFormatDDL. That works The problem I'm seeing occurs when I press the button to save the values from
the screen. I don't see the Item I selected from MediaTypeDDL. All the other fields are okay. This must be someThing simple, but I'm not seeing it.
I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)
