Web Forms :: Find The Selected Items In Checkbox List And Search There Email Id In Sql?
Jan 15, 2011
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.
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.
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 would like to find a way of running custom validation on a checkbox list. The reason why is because they were a radiobutton list. Then our client decided they wanted to be able to uncheck them (without a clear button) so in the end I had to change them to checkbox lists and make them mutually exclusive. On some of them, one must be selected and I downloaded this: [URL] to set them as required - worked nicely. Perhaps there's a way of building on this further to create some sort of custom checkbox validation. why I need this custom validation is because when the built form checkbox list = flat or maisonette then floor level is then required.
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 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.
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.
In the user form, the user has a chekboxList, and he can select more than one item.
how can I store those selected items in database, and how then I can retrieve them. " Is it true to make a separate column for each item, and then if selected, then that cloumn will have "1" and "0" for non selected. " Only that idea occurred to my mind, and I think that I can find better it.
I am currently facing a problem. How to get the latest selected value from a asp.net checkbox list? From looping through the Items of a checkbox list, I can get the highest selected index and its value, but it is not expected that user will select the checkbox sequentially from lower to higher index. So, how to handle that? Is there any event capturing system that will help me to identify the exact list item which generates the event?
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>
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();
I am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then Launch = 1 End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?
