C# - Both DataSource And DataSourceID Are Defined On Listview, Remove One Source?

Jan 26, 2011

I'm getting the following error, ever since I moved my DataTable to a different function. Both DataSource and DataSourceID are defined on 'TestView'. Remove one definition.By all means if you have tips on style / standards, I welcome that as well, I am very new to aspx coding. Any idea what could be causing this? It wasn't happening before when it wasn't its own function. Is it a local variable problem?

Here's the code for the code that binds and is highlighted in the error:

testDAO tda = new testDAO();
DataTable testTable = new DataTable("TestView");
testTable = tda.GetTestTable();
TestView.DataSource = testTable;
TestView.DataBind();

Here's the code for the GetTestTable():

public DataTable GetTestTable()
{
DataTable testTable = new DataTable("TestView");[code]....

List view in aspx file:

<asp:ListView ID="TestView" runat="server">
<ItemTemplate>
<tr id="row" runat="server" class='<%# Container.DataItemIndex % 2 == 0 ? "row" : "altrow" %>'> [code]....

C# - Both DataSource And DataSourceID Are Defined Error Using With GridView

Jan 26, 2011

But it's different situation on gridview.

<asp:GridView ID="Grid_Goster" runat="server" AutoGenerateColumns="False" CellPadding="4"
DataSourceID="SqlDataSource3" ForeColor="#333333" GridLines="None"
Height="144px" Width="316px">
<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:SqlServerCstr %>"
SelectCommand="SELECT * FROM [AVUKAT]"></asp:SqlDataSource>

And i get error like this: Both DataSource and DataSourceID are defined on 'Grid_Goster'. Remove one definition. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: Both DataSource and DataSourceID are defined on 'Grid_Goster'. Remove one definition. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using And in my .cs file there is code like this.

SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
Grid_Goster.DataSource = dr;
Grid_Goster.Visible = true;

i think this code works correctly. How can i solve this DataSource and DataSourceID problem?

Forms Data Controls :: Bind ListView DataSourceID To ObjectDataSource With Button_Click

Jan 12, 2011

I successfully bind ListView DataSourceID to ObjectDataSource but it binds only initially on Page_Load event.
When I want to bind another data through a Button_Click event, the new data doesn't bind.

aspx code:

[Code]....

Codebehind:

[Code]....

On Page_Load, I get result:

A1
<hr />
T1
A2
<hr />
T2
A3
<hr />
T3

When I Button1_Click, nothing happens, no error, no any more results and _airLineData is 53 records, not 3 records (A1T1 to A3T3) I want the binding to be with DataSourceID to ObjectDataSource (not through DataSource property and control.DataBind() method)

Get The DatasourceID Of The Datasource That's Firing The OnSelecting Event?

Mar 11, 2011

I have a couple different sqldatasources on an asp.net page that all fire the same onSelecting Event Handler. The reason for this is because the same code in the event handler can be applied to all datasources (which essentially generates filters in the queries dynamically). However, now I have another datasource that can still use most of the code, but needs to be handled slightly differenty. I could do this very easily if I could reference the datasource's ID that is firing the event (which I've tried), but this doesn't seem to be possible. Here is what I initially attempted to do:

protected void sdsTable_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
SqlDataSource sds = sender as SqlDataSource;
string dsID = sds == null ? "" : sds.ID;
if (dsID == "aDataSourceID")
{
//do this
}
else
{
//do that
}
//more code
}

This didn't work because sender is of type SqlDataSourceView and trying to cast sender as SqlDataSource returns null. So, I changed it to SqlDataSourceView:

protected void sdsTable_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{
SqlDataSourceView sds = sender as SqlDataSourceView;
string dsID = sds == null ? "" : sds.Name; //Tried Name property because ID isn't available
if (dsID == "aDataSourceID")
{
//do this
}
else
{
//do that
}
//more code
}

But this still doesn't work. SqlDataSourceView doesn't seem to have a property available that gives the datasourceID of the datasource that is currently firing the event. There is a SqlDataSourceView.Name property, but this is something different. Does anyone know if it is possible to get the ID of the DataSource firing the Selecting event when that event is being handled? If so, can you provide an example on how to do this?

DataSource Controls :: The Type 'System.Data.Linq.DataContext' Is Defined In An Assembly That Is Not Referenced?

May 28, 2010

I have a strange problem. I am adding a LinqDatasource object, and set the context:

[Code]....

Then I get this error:The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

On web.config I already have this:

<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

NOTE: The datacontext is in a different project (DLL proect) where I added a refernce to System.Data.Linq.

is there another way adding a refernce to a web project? or only though teh web.config?

Forms Data Controls :: GridView1 And Run The SQL Command

Mar 7, 2011

I started a C# web project in Visual Web Developer. I dropped a grid view in with designer and connected to my remote SQL database with the designer dialog based wizard. All is well there. I have in my program also a textbox where a user enters a zip code and clicks a button 'search'. When the user clicks search I want to run the SQL command "select * from flat_list where zipcode='userszipcode'". In other words the userszipcode is dynamic and different every time. It is my understanding I should use a SQLDataSource object but I do not know how.

Forms Data Controls :: Selected Value From Gridview1 To Load Gridview2?

Feb 21, 2011

I have a gridview1 with a Select column, which has a SqlDataSource that executes a Store Procedure.

I also have another gridview2, which also has its own SqlDataSource, but in this case, the Store Procedure has a parameter. This DataSource assigns as parameter the gridview1 control, and its PropertyName is SelectedValue. How can I load the gridview2 when gridview1 is clicked in the Select Column?
