How to pass parameter from tbx to tableadapter and return result to different tbx

Posted on 2008-10-22
Last Modified: 2013-11-07

I have a tableadapter with a query that returns a list of customers using an account number as the parameter. What i need is to take a string entered into a textbox (tbxAccountNum) and pass that to the adapter (customersTableAdapter) when an imgbtn gets clicked. The result, I then need to populate into another textbox (tbxCompanyName).

Here is the query from my tableadapter (FillByAccountNum, GetCustomersByAccountNum)
SELECT account_num, company_name, customer_id FROM dbo.customers WHERE (account_num = @account_num)

I am using C#.

Please let me know if any additional information is required.

Are you calling a method on the TableAdapter where you need to pass a parameter?

int accountNumber = int.Parse(this.AccountNumber.Text);

Here is what I have:

protected void imgbtnSearch_Click(object sender, ImageClickEventArgs e)
        string accountNum = tbxAccountNum.Text;
        customersTableAdapter customersAdapter = new customersTableAdapter();

I had to change "int" to "string" and FillByAccountNum gives the error: No overload for method 'FillByAccountNum' takes '1' arguments. Is what I have thus far correct?

If so: How do I assign the value returned to tbxCustomerName?

The Intellisense should give you an understanding of what you need to do.  GetCustomersByAccountNum is a function with a return, that you are ignoring in this case.  You need to look and see what the return type is and assign the return value to the TextBox.

Thanks but intellisense is of little help. What is the "vanilla" way to pass a parameter to a datatable, obtain the response and assign that value to a textbox?

If you can't see how Intellisense is useful here, then you need to see how to use it:
