Probably the best place to put it is in the button click event. Try this code to dynamically change the name of the column you are searching on: CSharpDataSource.SelectCommand = string.format("Select * FROM Employee WHERE {0} LIKE @filterVal",ddlColSelect.SelectedValue); Sal, to do something like this, I suggest that you put some code in your code behind.

A quick query for you regarding the above content - I have a dropdownlist, a text box, and a gridview. The dropdown list contains the gridviews column names. The user selects a column name they wish to filter in the dropdownlist and then as they type in the textbox the gridview's content should filter down accordingly. The issue I am having is that it doesnt seem I can use a paramter for both column name and its value: Is there anyway I can enable filtering of a gridview based on a particular column by data entered into a textbox?
