C# - RowFilter On A DataTable To Display In A Gridview?

Aug 10, 2010

I have the following code which doesn't seem to work. In the Page_Load function I populate the DataSet and display the results in a grid view.

newsCommand = new SqlCommand("SQL code here", dbConnection);
newsDataSet = new DataSet();
newsDataAdapter = new SqlDataAdapter(newsCommand);
newsDataAdapter.SelectCommand = newsCommand;
newsDataAdapter.Fill(newsDataSet, "Bulletins");

[Code]....

Yet the gridview shows the data it orignally loaded, and not the filtered data. The only thing I can think of is that I'm not using the DataTable in the Page_Load function.

Forms Data Controls :: RowFilter Working Like "OR" Instead Of "AND"?

Feb 14, 2010

I'm using the RowFilter within the gridview to filter out the grid. It works pretty good however, if a user enters in more than one value and hits search it seems to work like a "OR" instead of a "AND". Or it will display all values satisfying both rowfilters.

[Code]....

The code is pretty simple you have a group of textboxes and dropdown boxes in the front. When a user enters in the specifics and hits search it falls through each if statement until one is staisfies and sets the gridview....

State Management :: Datatable/Shoppingcart Isn't Working

Nov 25, 2010

I have copied this shopping cart from the net and incorporated it into my SearchResult.aspx. I understand the code and it seems simple enough but for some reason I am getting an error when trying to run it. Can someone tell me what is wrong below? The generated error stop at the following point: For Each objDR In objDT.Rows. I was thinking that object was not creative during the page load. So I added an

If IsDBNull(objDT) Then
makeCart()
objDT = Session("Cart")
End If

to check if that object exist or not then try to create it. But that didn't work either. :(

This is the error message:

Object reference not set to an instance of an object.
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.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

[Code]....

This is the code to the page. It take the data from a select button on a gridview1. That doesn't seem to be the problem so I didn't added onto here for you guys to see.
