how get string empty value from html decode asp.net gridview

Question

I have a gridview on my asp.net website. In this case, I wanna get value from the gridview row when selected. Here is my code behind when gvMyTask_RowCommand. I tried using if else condition to set specific value to my label.

string baselineStart = HttpUtility.HtmlDecode(gvrow.Cells[7].Text).ToString();

if (baselineStart == "")
    lblGLobalPlanStart.Text = "NoData"; //this condition never execute
else
    lblGLobalPlanStart.Text = baselineStart;

when my gridview column has data it worked for

lblGLobalPlanStart.Text = baselineStart; //store value

but when gridview column no data,this condition never execute

lblGLobalPlanStart.Text = "NoData";

is there any suggestion for this case?

Does it not hit the statement, or does the statement not execute/work?
Have you tried string.IsNullOrEmpty or string.IsNullOrWhiteSpace ?
