Web Forms :: Focus On Selected Item On Drop Down List?
Mar 26, 2010
Alright heres my scenario. I click on an event and a new aspx page opens. I have two drop down lists and three text boxes. All populated with the data from the database. But when the page opens the drop down lists always show the item that is at the top of the list. Not the actual item that is in the database.
So say the name John should be there in one and a car names honda. But instead it shows alex and acura. These are just examples. But it alwasy starts with the item at the top
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.
In my application i used drop down list dynamically so that if i enter the the value in the text box that many drop down list genrated with data from database. if i select the different iteam in the drop down list it will not changed it remains the first iteam of the dropdown list. if i use post back event is true in code part that drop down list is not visible.
nt i = 0; i < rows; i++) { TableRow row = new TableRow(); for (int j = 0; j < column; j++) { TableCell cell = new TableCell(); [code]...
how do i get the selected item in the drop down list and insert it into database (togethi populated the drop down with the values from the tables in database. It is dynamic, not static.i have a button in the gridview called 'add'. so when user clicks on it the row (whatever columns in the row) would be inserted into database. i am doing insertion/create for this.
I'm using Model-View-Presenter framework. When Loading a page, I'm having trouble setting the selected item that came from the Database.
In view, I know I need:
protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e) { presenter.DdlStatusSelectedIndexChanged(); // what should this pass? } Then in Presenter: public void DdlStatusSelectedIndexChanged() { view.DdlStatus = ??? // Should I pass the SelectedIndex? }
I also think that part of my problem is that DdlStatus I have as a List.
Interface:
List<StatusDTO> DdlStatus { set; get; }
The best I found is here (but needs formatted!) ---> [URL]
n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddl.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) { _btn.ValidationGroup = "G1"; } if (_selectedIndex == 2) { _btn.ValidationGroup = "G2"; } }
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.
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.
How can I make the first item in a drop down list non selectable. I want this first list-item to show up when the page is opened and want to populate the rest of the DDL from a backend DB. I don't want this default first item in the list to be selected (just want to show it as a default value)
I want it to look something like this.
Choose a State: (Appearing on the top of DDL, but cant be selected)
I fill a the drop down list with a SQL select query, but i want to add a first default item, something like "- Select an option -" or "All"
What im trying to do is make a dynamic SQL query, something like this:
SELECT * FROM table1 WHERE (value1 = ? AND value2 = ? AND value3 = ? )........ (or "like" instead of "=")
You are gonna have to select those arguments from 3 drop down lists, but i wanna have a default value on the top of the drop down list options and send a "*" as value if this option its selected, so the filter doesn't consider that value
I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement { public IEnumerable<selectListItem> InactiveProduct { get; set; } public string[] InactiveProductSelected { get; set; } public IEnumerable<selectListItem> ActiveProduct { get; set; } }
I've created a web form and added a drop down list like so
<asp:dropdownlist id="foo" runat="server"/> then I created a submit button <asp:button id="submit" text="submit" runat="server" onclick="OnSubmit"/>
I defined OnSubmit in my .cs file but I have no way of getting the selected value of the drop down list. When I created the drop down list, there was no variable auto generated in the designer.cs file. Vars are auto generated in there for <asp:textbox/> why not drop down lists?
I'm trying to make the selected item the value of an asp:Label if this is possibleI am putting my drop down list in like this
For ddlAdults As Integer = 1 To strNumberSlept CType(e.Item.FindControl("ddlEditAdults"), dropdownlist).Items.Add(new ListItem(ddlAdults.ToString(), ddlAdults.ToString())) Next ddlAdults
And I need to add a selected item in to be the value of strSelectedItem
Dim strSelectedItem = CType(e.Item.FindControl("lblAdults"), label).Text
I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.
Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)
Here is the code to get the data from the database:[Code]....
I have two drop down list on a page. The first one list projects and the second list users. The userlist is populated with an object datasourse that pulls a list of users for the selected Project.Whenever the Project list selection changes the second ddl Userlist always reverts to the first person in the list instead the person that was selected before a new Project was chosen.
I'm using vs2008 and add a dropdown list in my page. Default value of this control is "Digital". When I select another value from the list and press a button, next time the page displaying the same value, i.e Digital, not the selected value. I just want to show the selected value on the page.
I added 3 values on DropDownList controls. ID= DropDownList1. If a user selects a value from the DropDownList, I'd like to insert the value on my DB (DB = Test) and in Column (Column = LastName). Below is the code I get when I double click on the DropDownList.
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged End Sub
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.
I am trying to write a page that dynamically changes the options of one drop down based off the selected item in another one. I have varified the AJAX calls are happening correctly and vaified the root problem is that the new selected value of the dropdown is not being read during the AJAX postback. The code I am using is:
[Code]....
ddlGameName is the dropdown that the user selects from which calls the postback and then updates another dropdown. I can place a label in the updatepanel and assign the test as ddlGameName.SelectedValue.toString() and it will always read the first item in the drop down no matter which is selected. So how can I get it to read the updated selectedValue?
I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record. I am filling the dropdown list with a SQL DataSource I have tried a couple of example that I have found for selecting the item in the list but I am always getting the first item in the list as the selected item. This is what I am currently working with:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
