Passing Data between 2 ConLib user controls

[BryanWarmoth]

I am trying to build an application where a user chooses a product in the middle content area and then the product attributes will show up on the right side bar. I would like to have this done inside an update panel so that there is no postback. Is there anyway to make two different conlib user controls share data together on one page?

Thanks,
Bryan

Technically there will still be a postback, it's how the postback code is generated on the client side that changes when you use an update panel.

I pass values between controls using .Net session variables.

Thanks, I got it working using session variables but i am still having some problems with the ajax populating the information section. I can't seem to use an update panel because the 2 controls are in separate parts. My area where you choose the product is in the middle content part and the info should show up in the right sidebar. Any suggestions?

Perhaps this code snippet from my BuyProductDialog user control will lead you down the correct path. The trick is using an Able utility function to search the entire page for a particular control. Then you can direct-cast that reference into a new control and access the properties/methods of the original rendered control. You have no idea how long it took me to get working......

Code: Select all

                PlaceHolder phProductImage = (PlaceHolder)PageHelper.RecursiveFindControl(this.Parent, "phProductImage");
                UpdatePanel AJImagePanel = (UpdatePanel)PageHelper.RecursiveFindControl(this.Parent, "ImageAjax");

                string _ImageURL = _OptionChoice.ImageUrl;
                string _ImageAltText = _Product.ImageAltText + " (" + _OptionChoice.Name + ")";
                if (!string.IsNullOrEmpty(_OptionChoice.ImageUrl))
                {
                    phProductImage.Controls.Clear();
                    phProductImage.Controls.Add(new LiteralControl("<img id=\"ProductImage\" src=\"" + Page.ResolveClientUrl(_ImageURL) + "\" border=\"0\" alt=\"" + Server.HtmlEncode(_ImageAltText) + "\" />"));
                    AJImagePanel.Update();
                }

Finally! Thank you so much that worked perfectly!
