Question

I have a tree-view and datagridview on my form.

I will have an import option through which I can import txt files. When I select a particular file I will add it as a node to the tree-view and the data in that file will be displayed in the datagridview.

I will also have a context menu that has some options such as Close which will be displayed on Tree-view right click. If I select Close I will clear all the Nodes of tree-view and clear all rows of the datagridview.

But the horizontal scroll bar is not getting cleared can any one tell how to clear this?

Answer 1

you need to clear the columns of the datagridview

dataGridView1.Columns.Clear();

and before adding new rows. need to add columns using

dataGridView1.Columns.Add("Column_Name", "Header_Text");
