Hello. You'd better post some code in order to get better help. But I think the problem is, managed provider type, connection provider name is not given. you might wanted to use a textbox.text value, but yopu gave textbox, itself.

As I said, please post yout code to get help.

that's the way it is

Hi stealthassassin_1990,

Base on my experience, I think that you want to split a SQL statement, and there are several parameter's values come form the TextBox controls, but you maybe use like the following code snippet:

... fieldname = txtFieldName...

If so, you just need change the about code like this:

...fieldname = txtFieldName.Text...

I refer to the following line get the above conclusion:

[ArgumentException: No mapping exists from object type System.Web.UI.WebControls.TextBox to a known managed provider native type.]

Let me know if I have misunderstood what you mean. Thanks.

Hope it helps,

Hong Gang

I am getting same error, and isolated it down to this snippet:

If I exit after "exit 2" assignment, I see it in the textbox. That line works. If I don't exit, I fail on the "exit 2A" assignment and see the error message (displayed by catch code) instead of the string.

I must be missing something.

Would more code help, or just distract?

            this.txtMessageFromStore.Text = "exit 2";
            //return;
            try
            {
                this.txtMessageFromStore.Text = "exit 2A";

It seems that you have taken textbox control and you are missing the "TEXT" property for a textbox.

Just try this:

=txtFirstName.Text

enjoy..
