Control the size of a text box via a report parameter

We have some note fields that are very large so reports take up too many
pages.
However we would like to either limit the field to lets say 4 lines or all
lines via some parameter.
Is there any way to do this?Did you look into using the Left() function to limit the field content to a
certain length based on a report parameter? You could use an expression
similar to this for the textbox value property:
=iif(Parameters!RestrictLength.Value = True,
Left(Fields!LongDescription.Value, 200), Fields!LongDescription.Value)
MSDN documentation for Left():

Consuming Stored Procedure Output Param

This is my SProc:

CREATE PROCEDURE dbo.ap_Select_ModelRequests_RequestDateTime

/* Input or Output Parameters */
/* Note that if you declare a parameter for OUTPUT, it can still be used to accept values. */
/* as is this procedure will very well expect a value for @.numberRows */
@.selectDate datetime
,@.selectCountry int
,@.numberRows int OUTPUT

AS

SELECT DISTINCT configname FROM ModelRequests JOIN
CC_host.dbo.usr_smc As t2 ON
t2.user_id = ModelRequests.username JOIN
Countries ON
Countries.Country_Short = t2.country
WHERE RequestDateTime >= @.selectDate and RequestDateTime < dateadd(dd,1, @.selectDate)
AND configname <> '' AND interfacename LIKE '%DOWNLOAD%' AND result = 0 AND Country_ID = @.selectCountry
ORDER BY configname

/* @.@.ROWCOUNT returns the number of rows that are affected by the last statement. */
/* Return a scalar value of the number of rows using an output parameter. */
SELECT @.numberRows = @.@.RowCount

GO

And This is my code. I know there will be 100's of records that are selected in the SProc, but when trying to use the Output Parameter on my label it still says -1

ProtectedSub BtnGetModels_Click(ByVal senderAsObject,ByVal eAs System.EventArgs)

Dim dateEnteredAsString = TxtDate.Text

Dim selectCountryAsString = CountryList.SelectedValue

Dim conAsNew SqlClient.SqlConnection

con.ConnectionString ="Data Source=10.10;Initial Catalog=xx;Persist Security Info=True;User ID=xx;Password=xx"

Dim myCommandAsNew SqlClient.SqlCommand

myCommand.CommandText ="ap_Select_ModelRequests_RequestDateTime"

myCommand.CommandType = CommandType.StoredProcedure

myCommand.Parameters.AddWithValue("@.selectDate", dateEntered)

myCommand.Parameters.AddWithValue("@.selectCountry",CInt(selectCountry))

Dim myParamAsNew SqlParameter("@.numberRows", SqlDbType.Int)

myParam.Direction = ParameterDirection.Output

myCommand.Parameters.Add(myParam)

myCommand.Connection = con

con.Open()

Dim readerAs SqlDataReader = myCommand.ExecuteReader()Dim rowCountAsInteger = reader.RecordsAffected

numberParts.Text = rowCount.ToString

con.Close()

EndSub

What should I fix?

label1.Text = myCommand.Parameters("@.numberRows").Value

If I remember, I had this same problem, and found that you can't use the DataReader if you want to get the output parameter. I think you have to use DataSet.

Read the following for an explanation of why it is happening and how to get around it.

How do I do the DataSet approach?

ProtectedSub BtnGetModels_Click(ByVal senderAsObject,ByVal eAs System.EventArgs)

Dim dateEnteredAsString = TxtDate.Text

Dim selectCountryAsString = CountryList.SelectedValue

Dim conAsNew SqlClient.SqlConnection("Data Source=xx;Initial Catalog=xx;Persist Security Info=True;User ID=xx;Password=xx")

Dim dbDataSet =New DataSet()Dim dbAdapterAsNew SqlDataAdapter

dbAdapter.Fill(dbDataSet)

|||

You can do the following

Dim dbDataSet =New DataSet()
Dim dbAdapterAsNew SqlDataAdapter
dbAdapter.Fill(dbDataSet,"tablename")

dbDataSet.Tables("tablename").rows.count

In case you have only one table, you can use a datatable instead of a dataset

Dim dbDataTable =New DataTable()
Dim dbAdapterAsNew SqlDataAdapter
dbAdapter.Fill(dbDataTable)

dbDataTable.rows.count
