DataSource Controls :: Using Parameters For A Listview

Jun 4, 2010

I have webform with a listview control on it that uses 2 date values supplied by the user (via 2 text boxes) to dynamically set date range parameters for the datasource. The user enters two dates and clicks a button that runs the following code that sets the parameters:

[Code]....

This code works the first time the user clicks the button. But if they change the date values and try again, it only returns the result set from the first request. The parameters are not updated to the new values supplied by the user.

DataSource Controls :: Setting Parameters In ListView

Mar 17, 2010

I have a ListView that, among other things, in the EditItemTemplate, has a pair of related DropDownList controls, sort of a parent/child relationship. The selected value of the parent is used as a parameter for the SQL Datasource of the child. Outside of a control such as the ListView, this would be easy and I'd simply set up a ControlParameter for the SQL Datasource and life would be good. Within the DataList things are not quite so simple. My plan is to set the parameter of the child in the Selecting handler of its datasource. I have hard coded some values and this works the way I want it to. My problem is getting the "parent" value. I've got two theories on how to get this:

#1, I've tried instantiating the parent DropDownList but it is either not available at this point in the page life cycle or I just don't know the syntax to get at it from within the Selecting handler.

#2, I'm thinking I may have to grab the value from the underlying data for the ListViewRow that I am editing, but again, I do not know the object model well enough to get at those values.

Below is a code sample for option #1. As stated, setting the parameter works, but getting the value of the DropDownList does not.

Forms Data Controls :: ListView Update Parameters Don't Bind

Mar 9, 2010

I have a ListView where I am trying to implement Updating. My update parameters are not sent to update command correctly. The value sent is the original value and ignores what I type into the EditItemTemplate. Running a trace on my SQL Server verifies this. In this example, I am only trying to modify [dedamt]. What is wrong?

C# - Bind The Datasource Of A Nested ListView To The Parent's ListView Datasource?

Dec 13, 2010

I have triple-nested ListView controls on my asp.net page, each nested within another. I use the OnItemDataBound event in the 1st ListView to set the DataSource of the 2nd level ListView. The 3rd ListView is contained in the of the 2nd ListView. I want to assign the same DataSource to both the 2nd and 3rd level ListView datasource controls, but I cannot figure out how to access the 3rd level ListView in order to do that.

[Code]....

The level1_ItemDataBound method finds the level2 control, casts it as a ListView, sets its DataSource and executes the DataBind. At this point I'm stuck trying to get Level3.DataSource to be set to the same as Level2.DataSource.

Forms Data Controls :: Syntax For Passing ListView Data To SQL Input Parameters?

Dec 11, 2010

I have a ListView displaying data from Table A using a SqlDataSource.

I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure

(The scenario is much more complex but I've left out anything not relating to this exact problem).

I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.

This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":

[Code]....

Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.

What do I use instead of the word Description to reference this column in the Parameter?

DataSource Controls :: SqlDataSource With A Lot Of Parameters?

Sep 4, 2010

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.

DataSource Controls :: Can Use If Else In Sqldatasource If Else Parameters

Oct 4, 2010

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.

Ive passed in '02/06/2010' as the date, in the database, the Startdate column has several values of '2010-06-02 13:08:50.503' so I guess its not being found because of the time part.

DataSource Controls :: Using Table-valued Parameters?

May 19, 2010

This is my first attempt in using table valued parameters in my stored procedures. Please find the scripts down below. The idea is very simple. I'm trying to insert a new product into Products table and if the product has attributes, I'll insert them into ProductAttributes table which is where I use table-values parameters.

I was able to test the stored procedure manually. It's working fine. So the error must be in the C# code but there's not much to it.

Here's the DAL code in C# that calls the stored procedure:

[Code]....

Just in case you need it, here's what my Product object looks like:

And the ProductAttribute object is even simpler:
