Can I have a different view in a gridview cell?

In a 3 column asp:GridView, I need the 2nd column to be either a textbox, a dropdownlist, or a range of data(a from x to y) based on the value of the first column.
Is there a way to do that?

What I currently have is a standalone DropDownList. Then based on the selected value, a MultiView is activated. There are three views that can be activated. A plain TextBox, a DropDownList, and then 2 textboxes a From box and a To box for a range of values. I would like to know if it can be done in a GridView.

You can have gridview with 5 columns (where 1st and 3rd are fixed) and second is shown / hidden depending on the value of the first

Your gridview would then look like this:
1st
2nd a) textbox
2nd b) dropdown
2nd c) range
3rd

Then in CellFormatting event you check the value of 1st column and show / hide 2nd appropriately.

Something like this (in CellFormatting event):

C#

DataRowView drv = CType (dgv.Rows[e.RowIndex].DataBoundItem, DataRowView);
dgv.columns["2nda"].Visible = (drv["1st"] == value1);
dgv.columns["2ndb"].Visible = (drv["1st"] == value2);
dgv.columns["2ndc"].Visible = (drv["1st"] == value3);

e.FormattingApplied = True;
