I have a question. How can I auto populate two textboxes depending on another textbox? Example: TextboxFirstName, TextboxLastName are to be populated depending on TextboxEmail. So if a user enters their email address into TextBoxEmail then TextboxFirstName and TextboxLastName will populate with the user's first name and last name. Is there a way of doing this? Is so, can someone show me how?

Solution 1

Call the populate details in TextBoxEmail's TextChanged Event[^]

EDIT
-------------
Sample code

C#

protected void TextBox1_TextChanged(object sender, EventArgs e)
{
   DataTable dt = SomeFunctionReturnsDataTable(TextBox1.Text);
   string SomeValue1 = (string) dt.Rows[0]["SomeValue1"];
   string SomeValue2 = (string) dt.Rows[0]["SomeValue2"];
   TextboxFirstName.Text = SomeValue1;
   TextboxLastName.Text = SomeValue2;
}

Where you have "SomeValue1" and "SomeValue2", What should go there? I donn't understand or I'm lost somewhere. Where should this code go? Before the Submit Button or after?

"SomeValue1" and "SomeValue2" are variables. I have declared those in the code. Based on your question, I told you to use TextChanged event.

:( I think you should start to learn C# & ASP.NET from deep for your own good.
