i am making a site like linkedini have a datalist which show the search of peoples from database. my problem is that, i have mixed data to show in datalist.suppose datalist going to show only 2 label values, first is "who" second is "type". who can be of 4 types just like linkedin search, "A student","employ",Bussiness owner", "working independent"when student is pick in one label from database then college will be display in second labelwhen employ is pick in one label then company will be display in second column.It means i cannot bind the second label at designtime. and even at run time i have to bind each item of second label with approprite to first label. bec search can be mixed, means if 10 peoples are searched, then may be someone is employ, someone is student, and second label should show value appropriate their first label.

The issue I am facing is that the current page URL is getting appended to the 'LinkAddress'(the URL being fetched from the database) and thus,the final URL formed is not a valid one.Can someone suggest how do I remove the current page URL? Is there any way it can be done without writing code in the code behind page?
I am using a FormView control. The allows me to update records in the database. However, when a database field is null I can not update the field on the form. It works fine when the field is not a null value. I am not using any code behind (C#) to bind the data or manipulate the data.
I have read that when there is a null value in the database thatthere is no record in the "dataset". Can anyone show me how to bind a value in the form when there is a null value previously.
Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'. In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I have a database field called ImageLocation, I have the ImageUrl property bound to: Eval("ImageLocation", "{0}")I would like to bind the Visble property to false if the ImageLocation is null data. I can not figure out how to set the control properly, currently the Datalist shows me all the data and when the image location is null it shows me the name of the Hyperlink control which happens to be Hyperlink2.

I am attempting to bind data from a dropdown list that was populated from another datasourceID. I've bolded what I believe is relevant to this issue in the code below. But basicly its binding the proper county on the pull down menu but when I hit form submit it dosnt postback that info instead its null.
bind images from database to datalist i can do this but how i can bind the datalist to <li> tag means i need auto generate <li> tag for each image from database.
