Are you using updation using ajax(update panel) or normal postback.

In the page load the textbox value will become blank. you have to handle the IsPostback in the page load.

And also you can do this using some hidden fields also

Hello Brite,

You can try this code :

protected void btnUpdate_Click(object sender, EventArgs e)
{
GridViewRow gv = ((Button)sender).Parent.Parent as GridViewRow;
txtTask.Text = (gv.FindControl("lblTaskName") as Label).Text; // this TextBox is out side the gridview
}

Just try this code and let me know whether it satisfy your requirement or not.

Hope this will be helpful for you.

Hi,

I guess the problem is the postback. When you assign label value to your textbox control value has been assigned but due to postback or reload the data may be again value empty is assign back to the control. I rewuest you to please debug the program and check the values.

store the value in a session variable and after post back or in page load set this value.

So even if the page is post back you will always have this value for text box.
