I want to return all rows from a SQL Server 2008 database table into a SQL data source if a textBox field is blank. So I made a stored procedure with an if @date IS NULL clause.
Although the stored procedure seems to be working fine in Visual Studio 2008 the actual webpage displays no results.
I am guessing I have to send a DBNull value to the stored proc if textBox.Text == string.Empty. I tried the SqlDataSource1.SelectParameters.Add but it seems that I get a conversion error from DBNull.Value to string.
Is this the source of my problems or am I missing something else? How would I pass DBNull.Value to a stored proc if a textfield is blank?

In my stored procedure I have declared some parameters as NULL values(Optional Parameters).
In my C#.NET code I didn't use the parameters to pass values to Stored Procedure's NULL
Parameters. So I am getting Exception.
I don't want to pass parameters from my code.Because I have declared 30 parameters in my
Stored Procedure as NULL values.
Is there any other way to execute Stored Procedure from Front End without passing values to
Optional Parameters in SQL stored procedure?
I have a GridView sourced by a SQL Server stored procedure with several databound fields, including a money column for item values. My stored proc returns the data through a SELECT and everything looks good. The stored proc also has a single output parameter that sums the total value of the displayed data, and this value is displayed in a label above the GridView.
View 7 RepliesSo I finally managed to create a control which basically shows a bunch of Panels with an extra property. I use it like this:

This renders fine and shows the text in the TabPanel controls. However, when I replace the plain text with something a little more exciting, say an UpdatePanel so it looks like this:

If I take out the UpdatePanel and replace it with an ASCX control I made that simply puts database data into some DropDownLists, like this...
[Code]....
Then the page loads, but the data is not loaded into CustomerUserList1, and the dropdownlists within it are all blank. CustomerUserList1 has worked fine for years when used directly in a normal Panel/Page UpdatePanel.

I have to write stored proc to get the daily transaction for a specified date. Right now what i do is everytime i log a transaction in table3 I update table 2 with the count. Then i use table 2 to write the stored proc and to get the desired result. I have pasted my stored proc below with the output. My problem is when another subsystem is added in the AppInfo table i need to update my stored proc because i have hardcoded the subsystem name.

I have a stored proc. that returns the USL & LSL values for each of the 8 different Metrics. say, Defect Density (Upper Specification Limit) USL = 0.30 & Defect Density (Lower Specification Limit_ LSL = 0.05).

I've modified an existing strored procedure. It originally had one ouput parameter in the stored proc and it was set up as follows in the c# code that called it:
cmd.Parameters.Add("@Var1Param", SqlDbType.BigInt);
if (Var1 == 0)
cmd.Parameters["@Var1"].Value = DBNull.Value;
else
cmd.Parameters["@Var"].Value = Var1;
cmd.Parameters["@Var1"].Direction = ParameterDirection.InputOutput;
cmd.ExecuteNonQuery();
// Get Var1
Var1= dataMorph.ToInt64(cmd.Parameters["@Var1"].Value.ToString());
Just to clarify, this parameter was declared as OUTPUT in the stored proc but as inputoutput in the C# code. This worked fine. I have added another parameter to the same stored procedure and I want to retrieve both from the C# code. The C# code now is as follows:.................................

Currently whenever I need to send a request to a payment-gateway, for example, I redirect my page to another page on my website which has a form with several hidden fields. I then pre-populate the values of these fields server-side, and specify in the body tag something like 'onload="form.submit();"'
However, I'm wondering, rather than redirecting to this page, is there anyway that all this data can be collected and POSTed to the payment-gateway server-side?This will cut out the need to redirect the user to this blank page, and make everything a bit more tidy.
