DataSource Controls :: Binding Multiple Rows Of Data From SQL To A Web Form?
Mar 23, 2010
Im struggling with a way to bind multiple rows of sql data to specific controls, what im trying to acheive is having a list of questions / answers in my SQL db and loading them into my web form to build a questionaire.
The data i load into the form depends on criteria like which questionaire is it (there will be 2 seperate ones) and what language should it be loaded in, this will be controlled using drop down lists and passing these parameters to the SQL select statement.
The problem i have is i am unsure which method to pull the data out of the question column in my table, and bind it to seperate controls row by row, should i use a SQLDataReader or load the data into a dataset, or run a stored procedure to pull the data?
Which is the best way to get data from sql and bind it to controls in this situation?
i hav a gridview ... now i need to add certain number of rows... say 5 rows .... which would b blank .. the rows consist of itemtemplate of textboxes.. here is the grid ...
[Code]....
now i am binding this gridview with certain data say :
[Code]....
now the problem is if the row contains 2 data originally ... then it alwz shows up with only two rows with binded data... but what i want is 2 (databinded rows ) + 5 (empty rows with textbox ) = 7 grid view rows .... now how to do it ... after i hav binded the textbox with data already....with some empty columns corresponding to the above code ?
After creating a dataset, which has CRUD statements generated two or more tables, which Data Control should I use that will allow me to insert data into fields into 2 or more tables from a single web form. I'm trying to create a web form that will allow the user to input student information, such as general information, medical information, etc.
I am listing about 20 rows, each row represents an Order.Each row needs to have 3 buttons, each button click will perform a different action.I have 3 actions to handle each button post request, I am just unsure how to setup the Html forms for each button.
Should I create 3 forms for each button, per row in my listing?(that would mean 20 rows x 3 forms = 60 forms on a page)Is that 'ok' to do? (i.e. or is there a better way to do this?)
How to select more than one radio buttons and use model binding to attach the Roles to the model property public string []Roles?The difficulty i`m having is that though i`m having multiple rows, Only and only One radio button is selected and tha tof the last row. I have the following code:
I currently have a datasource that displays several rows on an editable gridview where the user can update several rows at once. Each row contains an ActivityTotal column per row. I'd like to sum all the ActivityTotal rows displayed and have one totalValue.
I am using a sql stored procedure which returns multiple result sets. By default Sql Datasource is binding the first result set to gridview. I want the second result set to be binded. I browsed all the properties in Sql datasource but could not find one to set this.
I'm trying to figure out how to update multiple rows in my Directory table, when a user changes their Street Number or Street Name in their profile. They can add multiple users to a directory and each user they add to the directory has this primary users UserId in it. So if the primary user changes their address, I want it to update the address for all the users they listed in the directory as well. I'm adding this to the On_Click in the Code Behind, so when they click to update their profile, it fires this function as well. This code may be way off, but here's what I have right now:
I want to insert almost 400 rows in one database call in asp.net. I am using .net 3.5 and sql server 2005. What should be the best possible way for doing that?.
I've have to delete multiple rows from database in a table . Which is the best way to delete data to optimize performance of sql server as well as asp.net.
I am populating a form trough a query so it will return multiple values, sometimes 5 or 6 or even more.Now when I press submit I need to save each form row in a database.table as a new entry. Other question is I have 3 check-boxes when the submit button is pressed it need to insert the value corresponding to the selected one, how to do that?
Code: @{ var db = Database.Open("quality"); var selectQueryString = "SELECT * FROM perguntas WHERE chklst_id=@0 ORDER BY id" var id = UrlData[0];
I am accepting query/queries from user (our support team) in a text box where user can enter only one query or multiple queries. I need to display result of all queries entered in the textbox. If it is SELECT statement then result of that statement in grid which is done. If UPDATE/INSERT/DELETE then total number of rows affected which is also done but if only one UPDATE/INSERT/DELETE statement is entered in the textbox.
If user enters 2 UPDATE statements and then a SELECT statement then how can I get number of rows affected for individual UPDATE statements just like SQL Server Qury Analyzer displays messages in its result pane.
e.g.
(6 row(s) affected) -- first UPDATE statement
(4 row(s) affected) -- second UPDATE statement
(16 row(s) affected) -- for SELECT statement (grid will also be displayed along with these messages).
I tried almost everything, SqlDataSource (returns count of first statement only), SqlCommand.ExecuteNonQuery and DataAdapter.Fill (returns count of last statement only).
I am a seasoned desktop developer but I am new to MVC, EF and web development in general. I have been following the MVC Music Store tutorial but using my own database and project instead of the one from the tutorial.
My project is a web front end to a configuration database that lets us implement new Markets (a.k.a. Customers) for our IVR. For the View that allows the user to modify an existing Market I use a ViewModel class that has two properties. One property (clientData) is an EntityObject populated from a single row of the Client_Data table. The other property (callflowSeq) is a List of EntityObjects populated from about 40 rows of the Callflow_Sequence table.
The "Get" Edit method of the MarketsEditViewModel displays the Edit View fine but when I modify the data only the Client_Data table gets updated.
Here is my ViewModel:
[Code]....
Here are the Edit methods from my Controller:
[Code]....
Here is my View:
[Code]....
It seems that I can't use UpdateModel() to update the Callflow_Sequence table but I can't figure out how to do it manually.
I have a page in which i need to show data in the form of a grid. Each row in the grid is made up of 2 sub-rows, the first sub-row consists of a dropdown, a textbox & a textarea. Whatever is entered in these controls should be displayed in the second sub-row in the form of labels at runtime (i.e. using javascripts)
There can be multiple rows like this. The grid would have a max of 30 row, not more than that. create this which one would be better, in terms of performance & complexity, a GridView or a DataRepeater?
Referring [URL] .... its a good functionality but instead of removing duplicate rows i need to make the cell of the column containing duplicate value blank
I have the following problem, i am using gridview to display some table info,, and during RowDataBound event i am binding another DataList control placed on gridview template column,,, the problem is that the DataBind() event of the gridview gives "Index 1 is either negative or above rows count." error.
I debugged alot,, when you disable the DataList binding it works,, but why the 2 not working together i dont know!!.
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I have a situation where in a legacy app (VB6) I have a grid which is populated by any one of a large number of (100+) stored procedures. Each of the procedures returns one or more rows with an identical list of columns (including column names, column data types, column order). I am basically looking at the (best) options to keep things reasonably light weight. Each procedure has its own set of parameters, each of which would result in different query plans etc. I have tried using each query to exec select into a (temp) table which is encapsulated into a "master" query which then returns a single results set, but it breaks SQL, the query optimiser returns an infinite number of rows - this is a MS documented issue. Looking for possible ways forward: generics, model view etc
In my application binding list is used to to bind the Data to Grid view. Now the requirement is to sort on 3 columns when I bind the data to the Grid View . How can I do this?
I'm pretty new at ASP .NET but not to ASP. I've got a form I need to create where I don't know how many entries will be added. It has the following format:
"Age" "Duration" "Period of Duration" "etc..."
Last30Days
1-5 Months ago
6-11 Months ago
Age
Age
Age
etc.
So the Age column always has the first 3 options and then an unknown number of Age values that can be inserted. I've created a table that has the first four fields (Last30days, 1-5months, 6-11months, age) and I was thinking I could just order by those 4 columns for display. The problem I have is I'm not sure on how to proceed. Does anyone have any good ideas on how to handle this situation? Ideally data entry people could use the same form for both entering and displaying the data.
