Do iteration that will replace the index of the control from 0 to max length.

C#

for(int i=0; i <= DataList1.Controls[i].ColumnCount; i++)
{
string pro_name = ((Label)DataList1.Controls[0].FindControl("lblpro_name")).Text;
        double price = Double.Parse(((Label)DataList1.Controls[0].FindControl("lblprice")).Text.ToString());
        //int quantity = int.Parse(((TextBox)DataList1.Controls[0].FindControl("txtquantity")).Text.ToString());
        //int quantity = Convert.ToInt32(((TextBox)DataList1.Controls[0].FindControl("txtquantity")).Text);
        string img = ((Image)DataList1.Controls[0].FindControl("pro_img")).ImageUrl;
}

The logic is here. Hope this one helps :)

Best regards,
Eduard

Solution 1

Then you will probably need to change it to use a loop.
Look at either a for[^] loop, or a foreach[^] - whichever is appropriate.

Why is this giving you a problem?
