Hi in my Student management system i have taken a table , in this i have taken columns as class , section, paper1,paper2,...........paper10

Because every class have diff - diff no of subject and no. of papers, so there i can not give the subject name in the place of papers.

For solve this problem i have maked a table in this i store the subject name class wise by this table we can know that ex: Paper1 is the English subject paper of the class 1st paper1 is the Math paper for class 10th.
Now when i display the students marks in the Datagridview then all the Paper1.....Paper10 display but i want to hide the unecessory column from there because if class 2 have only 6 paper then last for disappear.
and also want to dispaly the subjects name from my table. By replacing the Paper1...2 etc.
How can i do this?
i can make table for every class then it became very big,but became very easy, to do both things
Can we make dyanmic table which contain columns accroding to the class like if class 1st have 4papers then it contain 4column , and for class 2nd it contain 6 columns? Please help me

hi, if you are using datatable as datasource for datagridview (or even otherwise), you can add columns in the datagridview at the designtime by selecting Columns property in property window, and set datapropertyname of the column to corresponding column in datatable. Once you have all the columns defined in the gridview, then based on requirement you can set visible property of each columns at design time like grd.Column["Paper1"].Visible=false; This can be an alternative, although code intesive but will not consume too much of processing time.

Hi friend, You seem to following my suggestion, and start a new post. Actually, I think you do not need to create a dynamic datable, but you can form different view by using DataView which can be bound to DataGridView as well. jinge.
