I need someone familiar with Telerik RadGrid controls to help me.

Or, if you are not familiar, but are willing to help me troubleshoot, that is fine also.

Essentially, I have an event that gets raised when a "Buy" button is pressed.

The event that is raised (and internal C# code) looks like this:

    protected void rgCourseSelect_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        switch (e.CommandName)
        {
            case "ClearSelection":
                {
                    string isbn = (e.Item.FindControl("lblDataKey") as Label).Text;
                    //remove from cart
                }
                break;
            case "OOS":
                {
                    //Response.Redirect("~/Info/OutOfStock.aspx");
                }
                break;
            case "Used":
                try
                {

                    Telerik.Web.UI.RadGrid myradView = source as Telerik.Web.UI.RadGrid;

                    //RadGrid1.SelectedItems[0].OwnerTableView.DataKeyValues[RadGrid1.SelectedItems[0].ItemIndex]["CustomerID"]

                    e.Item.BorderStyle = BorderStyle.Dashed;
                    e.Item.BorderColor = System.Drawing.Color.LightGoldenrodYellow;
                    e.Item.BorderWidth = 2;

                    string usedprice = (e.Item.FindControl("lblUsedPrice") as Label).Text;

                    string title = (e.Item.FindControl("lblTitle") as Label).Text;
                    string isbn = (e.Item.FindControl("lblDataKey") as Label).Text;
                    string type = "Used";
                    double fusedprice = Convert.ToDouble(usedprice);
                    //Telerik.Web.UI.RadGrid myradView = source as Telerik.Web.UI.RadGrid;
                    string coursedetail = (myradView.Parent.FindControl("lblDescription") as Label).Text;

                    string newused = "Used";
                    int qty = 1;

                    ThemeAwareImageButton tmpUsedButton = e.Item.FindControl("imgAddToCartUsed") as ThemeAwareImageButton;
                    ThemeAwareImageButton tmpNewButton = e.Item.FindControl("imgAddToCartNew") as ThemeAwareImageButton;
                    ThemeAwareImageButton tmpRentalButton = e.Item.FindControl("imgAddToCartRental") as ThemeAwareImageButton;
                    ThemeAwareImageButton tmpEbookButton = e.Item.FindControl("imgAddToCartEbook") as ThemeAwareImageButton;
                    
                    if (tmpNewButton.CommandName != "OOS")
                        tmpNewButton.ImageUrl = "cart-buy.gif";
                    if (tmpRentalButton.CommandName != "OOS")
                        tmpRentalButton.ImageUrl = "cart-buy.gif";
                    if (tmpEbookButton.CommandName != "OOS")
                        tmpEbookButton.ImageUrl = "cart-buy.gif";
                    if (tmpUsedButton.CommandName != "OOS")
                        tmpUsedButton.ImageUrl = "cart-buy.gif";

                    tmpUsedButton.ImageUrl = "bought-check.gif";




                    AddItemsToCart(isbn, title, coursedetail, fusedprice, qty, newused, type);



                }
                catch (Exception)

                break;

                    string type = "Rental";
                    double fusedprice = Convert.ToDouble(rentalPrice);
                    Telerik.Web.UI.RadGrid myradView = source as Telerik.Web.UI.RadGrid;
                    string coursedetail = (myradView.Parent.FindControl("lblDescription") as Label).Text;

                    string newused = "Rental";
                    int qty = 1;

                    ThemeAwareImageButton tmpUsedButton = e.Item.FindControl("imgAddToCartUsed") as ThemeAwareImageButton;
                    ThemeAwareImageButton tmpNewButton = e.Item.FindControl("imgAddToCartNew") as ThemeAwareImageButton;
                    ThemeAwareImageButton tmpRentalButton = e.Item.FindControl("imgAddToCartRental") as ThemeAwareImageButton;
                    ThemeAwareImageButton tmpEbookButton = e.Item.FindControl("imgAddToCartEbook") as ThemeAwareImageButton;



                    if (tmpNewButton.CommandName != "OOS")
                        tmpNewButton.ImageUrl = "cart-buy.gif";

                    if (tmpEbookButton.CommandName != "OOS")
                        tmpEbookButton.ImageUrl = "cart-buy.gif";
                    if (tmpUsedButton.CommandName != "OOS")
                        tmpUsedButton.ImageUrl = "cart-buy.gif";

                    tmpRentalButton.ImageUrl = "bought-check.gif";


                    AddItemsToCart(isbn, title, coursedetail, fusedprice, qty, newused, type);



                }
                catch { }
                break;

            default:
                break;
        }

    }

Open in new window



Right now my focus is on the case of "Used".

string usedprice = (e.Item.FindControl("lblUsedPrice") as Label).Text;
string title = (e.Item.FindControl("lblTitle") as Label).Text;
string isbn = (e.Item.FindControl("lblDataKey") as Label).Text;
     
After these lines run, the variables "usedprice", "title" and "isbn" are all empty, although they clearly are there on the screen.


I believe the values are there, I just think that the way I am trying to obtain the values is not working right.


TIA for your help, folks!

Hi, Can you wait for two days, because I have all the video tutorials of the Telerik Rad Controls. I will try to upload on my blog as early as possible. It is very helpful to you for solving this problem.

Late yesterday I just barely solved this....so no rush....I think you can just let this go for now.

I will post my solution in a little while.

Essentially the "EnableViewState" needs to be TRUE or the information does not show-up.
