I have a label in a gridview where the text is set to <%Bind("lname")%> . I want to make it say thiis <%Bind("lname" + "fname")%>. I've been having a hard time making .net do this. I also want to add a "," or some other unrelated caracter?
I have a big problem...I have made a page has a Data FormView controland the insert template of this Formview control has DropDownList to allow the user to choose section (SectionsDDList)..and there's also another DropDownList allow the user to choose a teacher (TeachersDDList)...more infothe SectionsDDList get the section list from SqlDataSource control which the "Select Command" of is:"SELECT section_id,section_id FROM sections"the TeachersDDList get the teachers list from another SqlDataSource control which the "Select Command" of is:"SELECT teacher_id,teacher_name FROM teachers WHERE (section_id = @section_id)"finallyI want the TeachersDDList to be filled with teachers according to the selected section from the SectionsDDList...So,I enable the Auto postBack function of the SectionsDDListand add the next code for the SectionsDDList_SelectedIndexChanged event:TeachersDataSource.SelectParameters["section_id"].DefaultValue = ((DropDownList)sender).SelectedValue;be aware that both of the SectionsDDList & TeachersDDList have been Bounding to a column...and the problem I have faced is that:Exception Details: System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.maybe you want to know the Stack Trace:[InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.]

I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
I have a gridview on my asp.net web page. I bind the gridview to a dataset. The dataset has the following fields:
facility, date, patient name, description. Presently, the gridview looks like this when rendered:
ABC Hospital 10/1/2009 John Doe Sore Throat ABC Hospital 10/2/2009 Jane Doe Mumps ABC Hospital 10/3/2009 Bill Smith Flu XYZ Hospital 10/2/2009 Tom Jones Migraine XYZ Hospital 10/2/2009 Mary Mills Cold
I would like to ony display the facility once for each group. For example, ABC Hospital would only display on the first line and would be blank on the next 2 lines. I think I did this once before but cannot find the code. I have not been able to find a good example on the web.
