I am using AJAX ComboBox control (or I can use simple ASP.NET DropDown Control it does not matter) in my form. What I do is, I bind combo box control to my database and retrieve client names:
[Code]....
But here is the problem. I want First and Last names to go into separate TextBox controls (txtFirstName and txtLastName). Now it inserts Last Name and Firts Name in txtLastName control. At the same time I would really like to keep LastName + FirstName together in Combo Box.

How to get the value from the dropdown to return to the TextBox? The following does not work. You can select the item from list though.
<body>
<form id="form1" runat="server">
<script type="text/javascript">
function pageLoad() {
//Same Width
$get('ListBox1').style.width = $get('TextBox1').clientWidth;
}
</script>
<ajax:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajax:ToolkitScriptManager>
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<ajax:DropDownExtender ID="TextBox1_DropDownExtender" DropDownControlID="ListBox1"
runat="server" DynamicServicePath="" Enabled="True" TargetControlID="TextBox1"
HighlightBackColor="WhiteSmoke">
</ajax:DropDownExtender>
</div>
<asp:ListBox ID="ListBox1" runat="server" AutoPostBack="True">
<asp:ListItem>Item 1</asp:ListItem>
<asp:ListItem>Item 2</asp:ListItem>
<asp:ListItem>Item 3</asp:ListItem>

I have a dropdown list with the names of the months listed in it. These names are stored as int values but converted to string for display purpose. I also have a RadDatePicker control that will allow the user to select a specific date to overwrite the default date. The default date in the textbox needs to be set to the last day of the month selected (i.e. May 2010 would default to 05/31/2010).

I have a .Net dropdown list with a bunch of choices, and the final choice is 'Other'. When a user selects the choice 'Other' I need a textbox to appear next to it. I am able to do this with 'postback,' but as I have multiple dropdown list similar to this on one page I don't want to refresh the page each time. My question is, is there a better way to go about doing this? I also have to limit the use of Javascript. I can use C# in the codebehind page.

We have a page with quite a few textboxes and a dropdown list at the end. The dropdown list at the end is a "Result" and dependant on the result certain textboxes need to be filled in and this needs to be checked when they submit the page. I was thinking of using a custom validator

I am trying to bind a record to a textbox using a Dropdown selected index change. I get the error.
Conversion failed when converting the nvarchar value 'DrFirstName DrLastName,Ph.D.' to data type int. is it because I concatenate the name and prefix of the DR into the Dropdown list like this,
Code:
SELECT ID,EmailAddress, DrName + ',' + PreFix AS DrName FROM DrNames
Here is the dropdownlist code that I want to populate the textbox with the emailaddress in the table associated with Dr name and ID.
Code:
Private Sub DropDownList1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList1.SelectedIndexChanged
Dim dt As New DataTable()
If DropDownList1.SelectedItem.Text = "OTHER,..." Then
txtRx1.Visible = True
DropDownList1.Visible = False
End If

Let's say I have a gridview with some columns like, title, name, funding agency. Here's an example of what I want to do:
I want to display all the records in the gridview to start. There would be a dropdownlist that lets the user select whether to search by title, name, funding agency and a text box that lets them type in what they want to search for (and a button to start the search). After searching, the gridview would only display the records that matched the criteria.i already know how to connect datasets to the gridview, but i am using mysql database and writing code in vb.how to accomplish this task
