MVC :: DropDownList Can Either Select Item OR Save Selected Item Back To Controller?

Jul 7, 2010

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

C# - DropDownList With DataSource Doesn't Select Any Item?

Mar 5, 2010

I'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.

Web Forms :: Programmatically Select Item In DropDownList Based On Text Value

May 7, 2010

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:

Forms Data Controls :: Dropdownlist Postback Always Select First Item?

Mar 24, 2010

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?

Jun 12, 2010

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:

Data Controls :: Select Item DropDownList In GridView - Object Reference Not Set To Instance Of Object

Aug 30, 2013

I have a dropdownlist attached to a cell when edit is selected.  I am using the following code to populate the drop down list with the value that is on the row.

dlBU.Items.FindByValue((e.Row.FindControl("lblBU") as Label).Text).Selected = true;

This works famously when I have a value in the cell.  It fails when the cell has not yet been populated.  Is there an if then clause that if the value of e.Row.findcontrol("lblBU") is null no default value?

C# - Select Item In Formview Based On Drop Down Selected Item

Jul 4, 2010

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.

I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.

I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
