View 5 RepliesI'm creating a web server control that has an image button on it.The html for the control is done in the RenderControls of the code, the control devrives from WebControl, IScriptControl, INamingContainer.The button is coded as follow in the RenderControls:
System.Web.UI.WebControls.ImageButton img = new System.Web.UI.WebControls.ImageButton();
img.ImageUrl = "Url of the image";
img.Click += new ImageClickEventHandler(img_Click);
img.ID = this.ClientID + "_img";
img.CausesValidation = false;
imgLock.RenderControl(output);
The button apreas in the browser but when i click on it, the page postsback but the event handler for the button doesn't get fired, from what i can figure out, since the control goes throught RenderControls eachtime the page is posted back, the button gets redrawn and the event handling disapears.

I have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!
