Object reference not set to an instance of an object.
Hi,
In ASP.Net, (code behind C#) from a aspx page i am calling a function of different class(aspx page). In that function i have set a TextBox Text property -> tb.Text="Something" (TextBox is already there..no issues).
public void UpdateChatBox()
{
//tb= new System.Web.UI.WebControls.TextBox();
tb.Text="Something";
}
If I call this function from the same page it works fine, as i have mentioned its refernce in the class.
protected System.Web.UI.WebControls.TextBox tb;
But when I call the same function from another asx page (class); the line tb.Text="Something"; gives the famous error->
Object reference not set to an instance of an object.
Adding tb= new System.Web.UI.WebControls.TextBox(); doesn't olve the problem.
Can somebody please help.
Thanx in advance.
