Web Forms :: List Items Not Appearing As Selected?
Mar 19, 2010
I have a list with multiple selection enable, wen i do a loop in back end to see which items are selected it always just shows me the first one as selected only and everything else false.
I am new to ASP.NET and i have created a page where i am calling Fullname of person in Checkboxlist. When a user selects some names and clicks sendmail button , it should go into sql find out the email addresses of selected names and convert them to a mailto:aaa@ymail.com;abc@gmail.com; ask the user whichever mailaccount the user wants to use to send the mail to them.
There are 25 items in the list. I have selected one item at the time of project creation. But If I edit the project then the list box is showing more selected items instead of one item in the details page.
i want to apply color to selected number of items in checkbox list and seleted number of items in drop downlist for e.g color red for few items and black (default). I have a bit value set in data base so if bit is set to 0 then red and if 1 then back.
I have a listbox control data bound to a data source and I want to be able to get the value of each selected item so that I can use that information to form an insert query for another table. In other words be able to select a few items out of the returned list and get the selected value of each. I tried using a for each statement but came up with some strange numbers.
I am attempting to load a page to edit previously saved info from a SQL2008R2 database. When a drop down index changes, it is supposed to load the existing data from a table. Most fields work OK, but drop down lists throw the error. The list is bound to a different database and table from the existing data that is to be edited (if that makes sense). So, when the data is called for editing, that comes from tableB. The drop down list is bound to a different data source, tableA. When the initial data entry was done, the item exists in the table, so I fail to see why this error is thrown. There are many dealing with this symptom, and I have tried many proposed solutions with no good result. Here's the code that retrieves the data and throws the error...
Protected Sub DropDownList6_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList6.SelectedIndexChanged Dim conn As New SqlConnection("Data Source=server;Initial Catalog=database;User ID=user;Password=password") Dim cmd As New SqlCommand Dim reader As SqlDataReader
[Code] ....
The data is bring called from tableB. The error is getting thrown on the product.selectedvalue line..I think I understand the problem, but I am not sure how to resolve it.
I have code when I click on button I want show the value of selected List item in textbox but following code gisplay the item in alert,,
<html><script>function getValue(){ var x=document.getElementById("sel");for(var i =0; i < x.options.length; i++){if(x.options[i].selected ==true){ alert(x.options[i].value);}}}</script></head><body><selectmultiple="multiple"id="sel"><optionvalue="volvo">Volvo</option><optionvalue="saab">Saab</option><optionvalue="opel">Opel</option><optionvalue="audi">Audi</option></select><inputtype="button"value="Get Value"onclick="getValue()"/></body></html>
Looping Through Checkbox List and adding selected items to MS SQL DatabaseI don't want to store it using comma deliminator.I will need to do a search on analyze which users have what music in common.The image above is from a tbl_lookup_music table I created. MusicID, MusicNow how should I build the logicIF we have a user that has a tbl_profile table. And listens to many different types of music. How should We store the data.------------------------------------------------------------------------------------------CREATE TABLE [dbo].[tbl_lookup_music]( [MusicID] [int] IDENTITY(1,1) NOT NULL, [Music] [nvarchar](64) NOT NULL, ---- Type of music. CONSTRAINT [PK_tbl_lookup_music] PRIMARY KEY CLUSTERED ( [MusicID] ASC )WITH(PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY----------------------------------------------------------------------------------------------CREATE TABLE [dbo].[tbl_Profile_Music]( [ProfileMusicID] [int] IDENTITY(1,1) NOT NULL, [ProfileID] [int] NOT NULL, [MusicID] [int] NOT NULL,PRIMARY KEY CLUSTERED ( [ProfileMusicID] ASC)WITH(PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]) ON [PRIMARY]GOHow should I setup this table.
I have 2 web control calendars on a web page where I allow the user to select a startDate (WebControlStartDate) and endDate WebControlEndDate. Then the user can click the "Refresh" button to update the report that is displayed.
I am able to successfully store both the startDate and endDate value in a session variable and after the user clicks the Refresh button then both the StartDate and EndDates are chosend on the start and EndDate calendars.
However, both the StartDate and EndDate calendars are defaulting to the current month, meaning even if I select a previous month after refresh I will have to click back to a previous month in order to see the selected Day. After clicking refresh I want both month displays on the web control calendars to disply the months that were selected.
To summarize: each calendar is selecting the correct dates I just want the pageLoad to display each selected Month after the user clicks the Refresh button.
I'm having trouble getting selected items in a listbox to be seen as selected. On my aspx page there's a listbox and a button:
[Code]....
But if I change my condition to Not selected, the string does build, with every item in the list. So the Sub is reached, the items and their text and values are seen, but user selection of items doesn't work. What am I missing?
below is the code I have but I want to change the ddl.Deal(dropdownlist) to cbl.Deal(checkboxlist).. How can I loop throught each items if checked. and if all items are checked. to filter my data and show in gridview..
protected void btn_Click(object sender, EventArgs e) { myAPI.myWeb myAPI = new myAPI.myWeb(); myAPI.SearchParameters sSearchParameters = new myAPI.SearchParameters();
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'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
On a modular popup I have placed a checkboxlist and added items programmatically. Unfortunately I cannot get all selected items when I click the Ok Button. Me.CheckBoxListAddMyPoint.Items.Count is equal to 0 even if there are checked values.
Is it possible to select values from a List, where the items contain in a different list aswell?for example;
[Code]....
What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
I have a checkboxlist that gets data from my database and displays a list of items.
Item 1 Item 2 Item 3
I know how to get the chosen items, but i'm not sure how to get them in the order that they were chosen. This is my code to get the selected items.
[Code]....
So if I choose Item 3, Item 2, and then Item 1, when I display them on a label, the order is always Item 1, Items 2, Item 3. How can i preserve the order of the chosen items?
