View 1 RepliesI build a DetailsView and assigned datasourceID= SqlDataSource1
I bulid select command at runtime.
string selectcmd = "SELECT * FROM CDInfo WHERE CDID=@id";
SqlDataSource1.SelectParameters.Add("@id", Request.QueryString["id"]);
SqlDataSource1.SelectCommand = selectcmd;
//The only problem is that I try to call the select method
//but the compiler tell me I have to add a DataSourceSelectArguments
SqlDataSource1.Select();
//I don't know what argument to add, so I put DataSourceSelectArguments.Empty
// But it says variable "@id" must be decleared

I have a SQL query that returns about 5-10 records. For each one of these records I want to query another table using values in that row as parameters and create/populate a GridView. Can I create these GridViews and SQL connections programmatically in a for loop? I mean, I can't just plop ten GridViews and SQLConnections on my page at design time because I'm not certain how many rows will be returned in the first query. What should I do?
View 4 RepliesI'm trying to create multiple gridviews for a number of individuals based on a selection from a dropdownlist. The user will select his choice from the dropdownlist and from there a query is run to find the number of gridviews to create. Each gridview will also have its own data to bind. I believe I have most of it, I just can't get the gridview to show up. My thinking is to create the labels, then insert a gridview, bind it, and then repeat the process all over.

View 1 RepliesI'm having difficulty trying to create and persist controls inside of a gridview during postbacks. I have an unbound Datagrid control which is created with x number of rows and y number of columns during the Page_Load event.
[Code]....
During the RowDataBound event of the GridView, I create a placeholder control and then I create a label and add the label to the placeholder
[Code]....
On the first page load when navigating to the page, the grid dispays perfectly and the labels are created with no issues and I can see the "1" in every single cell of the Gridview. I basically need the labels in the cells to store an ID when the cell is clicked (the click event works with no issues, wired it all up with javascript) and Since the Cells to not exist prior to "Building the matrix" method, How can I persist the Label controls inside of the tablecells between postbacks so I can assign and read values from them.
I've read a number of online posts from 4guys from rolla and they demonstrate how to persist a handful of controls dynamically created in a staticly defined PlaceHolder conrol outside of the complicated setup of the gridview and have failed at adapting them. The golden rule seems to be to 'recreate' the controls during Page_PreInit during the postback, but I can't seem to get it working.
