DataSource Controls :: Bind Listbox Controll With An SqlDataSource?
Oct 26, 2010
I have a listbox controll and i want to bind it with an SqlDataSource.SqlDataSource must be declared in the code behind but i don't know where declare it(page init,page load...)and how to add sql parameter dynamically (parameters are the selected values of listbox, so they are multiple).
I'm trying to auto-populate a listbox of zip codes from a database table state_zipcode_plans based on the state a user selects from the previous listbox. I'm getting the error: Must declare the scalar variable @state_code.
I have a dropdownlist that's being populated from a SQL datasource. I would also like to have a tooltip for each dropdownlist list item on mouse over. I found the example below which adds a title attribute for each list item using the listitem text as a tooltip but I want to make the title/tooltip value another field in the database. In other words,
I have connected listview by using datasourceid that means by using "sqldatasource1" now i want to change value of listview at run time according to search so for that i am using datasource at codebehind. but it give an error
"listview have already bind with datasourceid you can not bind it with datasource"
I have a list box (that uses a SQlDataSource) that has a list of jobs. I have a grid view (that also uses a SQLDataSource) that has the items used in each job. I want to bind the list box value to the gridview on the client side, i.e. when the user clicks on a different job in the list view I want the grid to show the items for that job.
Also, at formload I want the gridview to show the details of the first job on the listview.
i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
i am facing a minor problem but can't find out its syntaxi have listview, and inside the template i have 2 labels, in design time i bind 1 label to one column thatis 'type' and depending upon this type i want to bind other labels to different columnsif type is question than 2 label will have to show data of question columnif type is job than 2 label will have to show data of job, so on........how to accomplish this,in databinding event handler i can check the value of typebut i want to know the syntax of binding 2 label in run time, with different fields using EVAL
I need to populate a listbox with queries from 2 sql tables, but I can only see how to populate it with 1 datasource.
Do I need to do some hand coding? If so, where should I put it?
I'd also like to add some text items to the listbox so I could say populate the listbox with a query, plus an "other" option, so that if "other" is selected, a textbox will appear that will let the user specify a new item.
I am using Visual Web Developer (VWD)and I dragged in i.e created a Gridview. In the codebehind of the page, I will like to declare an sqldatasource and get data from a database using the sqldatasource and then bind the sqldatasource to the Gridview. PS: I know how to drag-in an sqldatasource and attach it to the gridview using VWD but this time, I want to do this declaratively in the codebehind.
I am now trying to bind data from SqlDataSource into a textbox, but the problem that I face is that my DataSource only return a single row. So i don't place my textbox inside any DataView or listview.
i have a sqldatasource which will return 1 field (1 row) for an ID. I need to get that result and display it on a textbox. I would do it using a stored procedure (this was already made) but i was thinking sqldatasource is easier. Is there a way to bind that result onto my textbox?
I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username and if gender supplied SELECT * FROM [this_table] WHERE gender = @gender and if both supplied SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City, @State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.
i use below sqldatasource for search within a gridview and it is working fine.i just add this control and set gridview datasource id to sql datasource id .but i need the same in codebehind dynamically.i need like this becuase i need to search in three textbox but before i use one textbox. so could someone show me a example how i add a sqldatasourse in code behind and set filter parameter for search from a gridview.
