This peice of code, works perefect while runs via Visual Studio 2010, however after publishing, numbers are converted to integer. Thus it can't be inserted into Sql server database .... Server OS: Windows 2003 x64 IIS: 6 .Net Framework: 4.0
i want to bind the records from the DB to ajax combobox dynamically based on the serach criteria. the record count may be around 6000. use ajax combobox and show 10 records at a time. how to do this. i am new to ajax combobox.
The web page I am trying to (slowly) build should allow users to add whichever user controls they want on their page, and order them whichever way they like. This is saved in a database.
So each user could have a different number of controls on the page.
This is the design code, at the minute the user controls are fixed and are not loaded dynamically. They user controls are stored in 'blocks' which look like widgets on the page and can be dragged about to different columns. For each user the layout is stored in the DB i.e. which blocks are in column 1 and which blocks in column 2 etc.
How could I change this so that it can create a 'block' div for each user control returned from the database and put the user control in that block and in the right column?
untill now every thing is ok and when I select Item from ddlzoneE ,DdlDistrict's Item change but when I add below code in Page_load Event it didn't worked
