May 15, 2010

what i would like to do is when the value of my sqldatasource is returned, then if it is null, run a code, in my case, redirect them to the login page, heres my code:

string connectionString = ConfigurationManager.ConnectionStrings["PokemonPlanetConnectionStrings"].ConnectionString;
string insertSql = "SELECT * FROM LoggedInUsers WHERE UserId = @UserId";
using (SqlConnection myConnection = new SqlConnection(connectionString))

[Code]....

Now what i would simply like to do is, if the select statement searches the database, and the result is not found, the simply redirect them to "register.aspx"

DataSource Controls :: Create Update Command In Code Behind?

Feb 3, 2011

I have a detailsview which I am populating using a SQLDATASOURCE, which is bound to a table in a SQL db. Because the number of columns in the table will change, I am using SELECT * from [TABLENAME] to populate the view, this works fine.

My problem is that I need to also be able to update the table and I thought the best way was to generate the updatecommand in the code behind. This is no problem, code is as follows:

[Code]....

But the next stage is to create the relevant parameters for the update command. Does anybody have any thoughts on this? All of the information I have found for the updateParamater reference knowing the final value.

What I really need to do is the code behind equivalent of

<asp:Parameter Name="PARAMETERNAME" Type="Int32" />

Not sure whether this is possible.

Query Datasource From Code-behind Versus SqlDataSource

Aug 28, 2010

What ive been using now is getting datas in code-behind, passing datasource into a Session, re-binds it to a gridview whenever there's paging/sorting needed. What i want to know is what is better if its performance we are talking about?

Is it datasource into a session Or SqlDataSource for which I know whenever paging/sorting needed is that sqldatasource opens up a DB connection to get the datas again?

DataSource Controls :: How To Build Select Parameters Dynamically In Code Behind

Apr 9, 2010

I have SQLDataSource for my gridview. By default it works fine but i need to determine a few things before calling my procedure. By this i mean i need to determine a few things about the fields completed and set a flag to determine where the procedure will look.

I found a few examples online on passing parameters in code behind, but cant seem to get them to work. Here is what i tried and cant get results back. When i execute the procedure on the SQL side with the same parameter values, it works, so i know its returning results, so means my values are not being sent or im doing something really wrong. I have some of the lines commented out so the page can load and display for now.. but i need to get it working with custom parameters and flags.

Here is my SQLDataSource:

DataSource Controls :: Binding An ObjectDataSource To A Property In Aspx Code, Not Code-behind

Dec 3, 2010

I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:

[Code]....

I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like
[Code]....

This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?

Forms Data Controls :: Trying To Use A Couple Columns From SqlDataSource In Code Behind?

Jan 29, 2010

Basically, what I want to do is to get all my data in 1 statement and then pull data from that into a GridView. I already have the columns that I want displaying in the GridView, but now I want to insert a footer row in between the header row and all the datarows, that contains a couple columns that will be the same for every row in the GridView. So something along the lines of this:

Header1 Header2 Header3
Dept: Technology
data1 data2 data3
data4 data5 data6
data7 data8 data9

The thing is, I don't know what that "Dept" will be, so I want to pull it from my SqlDataSource that already has it.

ASMX Web Service Online Works When All Of The Code Is In One File Without Code-behind?

May 3, 2010

I have an ASMX Web Service that has its code entirely in a code-behind file, so that the entire contents of the .asmx file is:

<%@ WebService Language="C#" CodeBehind="~/App_Code/AddressValidation.cs" Class="AddressValidation" %>

On my test machine (Windows XP with IIS 5), I set up a virtual directory just for this ASP.NET 2.0 solution and everything works great. All my code is separated nicely and it just works.However, when we deployed this solution to our Windows Server 2003 development environment, we noticed that the code only compiled when all of the code was dropped directly into the .asmx file, meaning that the solution didn't work with code-behind. We can't figure out why this is happening.

One thing that's different about our setup in our development environment is that instead of creating a separate virual directory just for this solution, we dropped it into an existing directory that runs a classic ASP application. So here we have a folder with an ASP.NET 2.0 application within a directory that contains a classic ASP application. Granted, everything in the ASP.NET 2.0 application works if all of the code is within the .asmx file and not in code-behind, but we'd really like to know why it's not recognizing the code-behind files and compiling it correctly.
