i have a dropdown list with values
America
Asia
Europe
I need to the display the ddl as Select Type and when i click the dropdownlist to see the values in it, it should display the three values, but i should not use Select Type as a list item and it should not be displayed in the list. It should only be used as a default text in ddl.
I have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL

I have created the following select list item on a controller. code goes here........
select new SelectListItem
{
Value = c.Status_ID,
Text = c.Status_Description
};
And i made the required modification to the view and the select list was displayed successfully.But i faced the following two problems:-
1. i need to use the same select list in more than one controller , so for now i have to insert the same code in each controller to add the select list, so is there a way to define this select list in one place and then reuse it in all the related controllers
2. when i select a new value from the select list and i click on save button , the old value for the list will still be displayed ,and also no effect to the DB will be made.

View 2 RepliesI'm using a DropDownList with a data source which successfully populates the list. However, I want one of the items to be selected, namely the one where the value matches the path and query of the current request.
ddlTopics.DataSource = pdc;
ddlTopics.DataBind();
foreach (ListItem item in ddlTopics.Items)
{
item.Selected = item.Value.Equals(this.Page.Request.Url.PathAndQuery);
}
Using the debugger in Visual Studio 2008 reveals that item.Selected becomes true exactly once in the loop, but the rendered select has no option that is selected.
I'm using Visual Studio 2008 version 3.5. I have a dropDownList with over 800 names. The user wants to be able to type in it and select the name. I have seen this functionality in Telerik combobox but do not have license. How this functionality can be accoplished?

I have a databound dropdown list (ASP.net). I want the page to load with a certain item as the selected item.
I am not adding a blank first row (thats not what i need)I find that I can get this to work with "AppendDataBoundItems" to true, but the side-effect is that I have all the items listed twice.
I used scroll bar fo my dropdownlist

<asp:DropDownList ID="DDLcity1" runat="server" CssClass="DDlcityE" OnSelectedIndexChanged="DDLcity1_SelectedIndexChanged"
ForeColor="#ca0202" AutoPostBack="true" onclick="onSelectMouseDown()" onfocusout="this.size=1;">
<script>
function onSelectMouseDown() {
document.getElementById("<%= DDLcity1.ClientID%>").size = 10;
}
</script>

Here's what I want to accomplish: I have two .aspx pages, the first page with a ddl to select a vendor (SelectVendor.aspx), and one to add a vendor (NewVendor.aspx), if it's not in the first one. If a user adds a new vendor on the NewVendor.aspx page I want the page to automatically redirect back to SelectVendor.aspx and have the ddl automatically select the new vendor that was just added. Here's where I'm at so far: If a vendor is not listed in the ddl on SelectVendor.aspx, a user can click a button to navigate to a page to add a new vendor (NewVendor.aspx). On NewVendor.aspx the user types the name of the new vendor in a textbox and clicks an insert button to add the new vendor, then the page is automatically redirected back to SelectVendor.aspx with the new vendor name added to the QueryString. For example, let's say a user adds a vendor name "Best Vendor": The page is redirected back to SelectVendor.aspx as "SelectVendor.aspx ?vendor=Best Vendor"Now all I need from here is to have the ddl programmatically select the new vendor by the text value in the QueryString.
Here is the code that I'm having trouble with from my Page_Load routine for SelectVendor.aspx:

I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?

I have been trying for a while to populate a formview when I select an item from the dropdownlist. The dropdownlist is outside of the formview. For some reason, when I select a different item it does not change in the formview. Only the first item of the list shows up. I don't know where I'm doing wrong. I tried many things and suggested informatioin and I still could not get it to work. When I do try to switch I get this error message:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I have a Dropdownlist filled from database. Its datavaluefield has a combination of 2 values from database as :
Select (convert(varchar,DoctorID)+'*'+Ltrim(RTrim(DoctorAddress))) as DoctorIDAddress
ddlDoctorName.DataValueField = "DoctorIDAddress"
now while updating the form i want to select value in dropdown list with a combination of two values from database table.
ddlDoctorName.SelectedValue = Securities.HTMLEncode(dr("ReferredByDoctorID").ToString()) + "*" + Securities.HTMLEncode(dr("RefAddress").ToString.Trim)
but when i HTMLCode my Address field and it has '&' saved in it, then it encodes it as '&' and ddl don't have selected value.
so , is there any way to select an item value from ddl using like operator or other :
ddlDoctorName.SelectedValue = Securities.HTMLEncode(dr("ReferredByDoctorID").ToString()) + "*" +"%"

I have a DetailsView that binds a User's Profile data into an ItemTemplate upon the Page_Load. When the user chooses Edit Mode, all of the Data is correctly carried over, except for the DropDownLists selected values. If on the ReadOnly page, the user's data shows "Male" for the Sex, then on the edit Mode page, I would like the DropDownList that gets the sexes from the database ("male", "female"), to have automatically selected "Male" in the DropDownList, not the lowest indexed item.

I have several DropDownLists which get data from database, that is,
first DropDownList has static data, second DropDownList gets data according to selectedItem of first DropDownList, and so on..
There cases when second DropDownList has only one item, in that case I cant call SelectedIndexChanged.
How to manage it ?
