C# - Dropdown List Selected Item Always Set To Default Value
Jan 17, 2011
I wish to pass values of the selected items into a database and however noticed that the selected item is not what is sent into the database you can see in the snap shot below. during run time the following value is recorded. Where did it all go wrong with the dropdown lists selected item? Counting on your intelligence.
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.
I have a drop down list control populated with items and some code to take the currently selected item value. The problem is I only get the value of the first item in the list regardless of what item is actually selected. Here is my code to populate the drop down:
protected void displayCreateCategories() { StoreDataContext db = new StoreDataContext(); var a = from c in db.Categories orderby c.Name select new{catName= c.Name, catId=c.CategoryID}; ddlCategory.DataSource = a; ddlCategory.DataTextField = "catName"; ddlCategory.DataValueField = "catId"; ddlCategory.DataBind(); }
To get the value of the currently selected item which in my case is always of type integer I do label1.text=Convert.toInt32(ddlCategory.SelectedValue); I get the selected value, but it is always for the 1st item in the list. I'm pulling my hair out over this.
how i can set the default selected value for a dropdown list. My actual code is:
[Code]....
the GetAvatars() function return a List<MyObject> that contains the avatars informations such as filename and file url. I don't know if i this is correct, anyway i want to display a selectbox that shows the list of the avatars in a folder with a predefinited avatar selected and i would like to show an image near the selectbox with the current selected avatar. How can i do it? I don't find any way to set the default value
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.
Does anyone know how to do this so when I select something the 1st dropdown and the 2nd one becomes visible and populates list from a Select statement. I really need help on how to do in an aspx and not on the code behind page.
I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day LotID SlotID WaferID VendorID ToolID LocationDetected ProcessStep Stage Precipe WaferStartMaterial WaferStartVendor WaferStartLot WaferDiameterCOA WaferMapTitle BreakPoint BreakpointSide BreakpointMeasurement
I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.

"This screenshot demonstrates some of the styling options provided by the CSS, including the style for the selected About menu item"...In the screenshot the "About Us" menu item is highlighted but the page's content is the "Home" page content, not "About Us" page.
