I have a bunch of textboxes on my asp net page and on TextChanged event I want to run a stored proc to return a Name based on user input If I have a block of code like TextBox t TextBox sender string objTextBox t ID how can I get the Text value of objTextBox

if sender is TextBox var text sender as TextBox Text

[c#] Getting the .Text value from a TextBox

Use this instead:

string objTextBox = t.Text;

The object t is the TextBox. The object you call objTextBox is assigned the ID property of the TextBox.

So better code would be:

TextBox objTextBox = (TextBox)sender;
string theText = objTextBox.Text;
