Hello,
I have a method that allows users to add certain id's and all its details to a Grid. The grid also has a row deleting option. When the user is clicking on that button or clicking on the next button it throws this message. I' m so lost. Please advice how I could get around this problem.
thanks Here is my code that adds these items to Grid
protected void btnAddStyles_Click(object sender, EventArgs e)
{
// Add items entered to grid
DataTable dt = null;< ...
Go to the complete details ...
