I have written the attached code but I'm not too sure how I can put the result of my stored procedure into my dataset which will then allow me to bind my ReportViewer control to the filled dataset...
ReportViewer1.Visible = true;
        SqlConnection thisConnection = new SqlConnection(thisConnectionString);
        System.Data.DataSet thisDataSet = new System.Data.DataSet();
        SearchValue[0] = new SqlParameter("@DueDate", DropDownList1.SelectedValue);
 
        SqlCommand cmd = new SqlCommand("proc_ShowCrucialByDate", thisConnection);
        cmd.CommandType = CommandType.StoredProcedure;
 
        thisDataSet = cmd......?
 
        ReportDataSource datasource = new ReportDataSource("CrucialDatesDataSet_proc_ShowCrucialByDate", thisDataSet.Tables[0]);
 
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(datasource);
        if (thisDataSet.Tables[0].Rows.Count == 0)
        {
            lblMessage.Text = "Sorry, no products under this category!";
        }
 
        ReportViewer1.LocalReport.Refresh();

You need to call the Fill() method of a SqlDataAdapter to fill a dataset;

Check out the code here;

http://msdn.microsoft.com/en-us/library/system.data.dataset(VS.71).aspx

Excerpt attached..
Dim adpProducts As SqlDataAdapter = new SqlDataAdapter()
      adpProducts.TableMappings.Add("Table", "Products")
      Dim cmdProducts As SqlCommand = _
      new SqlCommand("SELECT * FROM Products", cnNorthwind)
      adpProducts.SelectCommand = cmdProducts
      adpProducts.Fill(ds)
      cnNorthwind.Close()

try the below code.
 

 cmd.CommandType = CommandType.StoredProcedure;
 // cmd.parameters stuff
 //create our DataAdapter and DataSet objects
SqlDataAdapter SqlDA = new SqlDataAdapter(cmd);
DataSet objDS = new DataSet("DataSetName");
		
//fill the dataset
SqlDA.Fill(objDS);
 
// thats it... you have objDs filled with storedpro information

I have now changed my code to the attached but I get the following error:

"System.Data.SqlClient.SqlException: Procedure or function 'proc_ShowCrucialByDate' expects parameter '@CrucialID', which was not supplied"

I have a dropdownlist control which is bound to a field value (CrucialID) of one of my database tables. What I'm trying to do is pass the selected CrucialID to the dataset and then fill the dataset on that ID value. From the error it doesn't look like this ID is getting passed to my dataset?

Thanks.
ReportViewer1.Visible = true;
        SqlConnection thisConnection = new SqlConnection(thisConnectionString);
        SqlCommand cmd = new SqlCommand("CrucialDates.proc_ShowCrucialByDate", thisConnection);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        System.Data.DataSet thisDataSet = new System.Data.DataSet();
        SearchValue[0] = new SqlParameter("@CrucialID", DropDownList1.SelectedValue);
        da.Fill(thisDataSet);
        
        ReportDataSource datasource = new ReportDataSource("CrucialDatesDataSet_proc_ShowCrucialByDate", thisDataSet.Tables[0]);
 
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(datasource);
        if (thisDataSet.Tables[0].Rows.Count == 0)
        {
            lblMessage.Text = "No Crucial Dates are due!";
        }
 
        ReportViewer1.LocalReport.Refresh();

This is how I put together SQL Parameters. The value is set differently to yours;
SqlParameter startDateParameter = new SqlParameter("@startDate", SqlDbType.DateTime);
            startDateParameter.Direction = ParameterDirection.Input;
            startDateParameter.Value = startDate;//start date
            command.Parameters.Add(startDateParameter);

I'm saying my tried and tested syntax is different to yours. Your choice what you use.

I don't see anywhere in your code where you assign the parameter array to the query (SearchValue).

In the example code there is a line which I've attached as a snippet, but I can't see an equivalent in your code?
thisDataSet = SqlHelper.ExecuteDataset(thisConnection, 
                      "ShowProductByCategory", SearchValue);

Yes, if you read at the very top of the link that I sent you he is using microsoft application block which I am not using so I have to call the stored procedure via the SQL Command object without using the SQL Helper class, that's what I was attempting to do with my code. Do you know of a better way?

Thanks.

Didn't you sort this out by raising yet another thread on the forum?

That thread used a different approach which created another problem if you read the thread. Your solution did work in the end (attached) so I will close this question and award the points.
ReportViewer1.Visible = true;
        SqlConnection thisConnection = new SqlConnection(thisConnectionString);
        SqlCommand cmd = new SqlCommand("CrucialDates.proc_ShowCrucialByDate", thisConnection);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        System.Data.DataSet thisDataSet = new System.Data.DataSet();
        SqlParameter crucialDueDateFromParameter = new SqlParameter("@DueDateFrom", SqlDbType.DateTime);
        SqlParameter crucialDueDateToParameter = new SqlParameter("@DueDateTo", SqlDbType.DateTime);
        crucialDueDateFromParameter.Direction = ParameterDirection.Input;
        crucialDueDateFromParameter.Value = tbCrucialSearchDateFrom.Text;
        cmd.Parameters.Add(crucialDueDateFromParameter);
        crucialDueDateToParameter.Direction = ParameterDirection.Input;
        crucialDueDateToParameter.Value = tbCrucialSearchDateTo.Text;
        cmd.Parameters.Add(crucialDueDateToParameter);
        da.Fill(thisDataSet);
 
        ReportDataSource datasource = new ReportDataSource("CrucialDatesDataSet_proc_ShowCrucialByDate", thisDataSet.Tables[0]);
 
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(datasource);
        if (thisDataSet.Tables[0].Rows.Count == 0)
        {
            lblMessage.Text = "No Crucial Dates are due!";
        }
 
        ReportViewer1.LocalReport.Refresh();
