I wanted to create a simple photo album just like facebook album feature Im able to display all albums, all pictures in thumbnail size in the album, but failed to view the image i wanted to view in normal size. This is my code in the Albumpicture.aspx which contain all images of that particular album
Then i use a blank page as a handler to read images from binary format in my database
Lastly, the albumID and photoID will pass to the photopage.aspx to display the image
But when i wanted to view the image in photopage.aspx, it shows a blank page. No error and nothing comes out.
I am trying to find the text property of a label that is nested within a DataList within a FormView. The FormView and the DataList have different datasources.
What I actuallt need to do specifially is assign the number of rows in the DataList to the Label in the DataList. I used the code below to find it but it keeps giving me an error about not finding the object;
I've got a multiline textbox inside the ItemTemplate of my Datalist, which is set to visible=false.I've got a button right above it, with the click of that button, all I want to do is make it visibleI've tried xtNewNote.visible=truethe ID of the textbox has a blue squiggly under it and I'm told that 'txtNewNote is not declared'and I've tried Dim txtNote As TextBox = CType(dlProject.FindControl("txtNewNote"), TextBox) txtNote.visible=trueHere, I just get an object not found when it gets to the second line
I am using a datalist to display data from a database.Except for 1 column all the other column values are getting repeated so I am hiding all the other column values when the datalist repeats itself.However, the unique column value is not getting rendered properly because there are many line breaks in between.I am not using any web control to display the static text and I am not sure if that would help.I just want to improve the final display so that the datalist looks consistent.I am attaching my code.
