How to hide one column of dx:GridControl in PrintPreview window?

Question

I have a DevExpress GridControl which contains many columns. Now during Print/Export i want to hide one column. Whats the logic? How can i do that?

Answer 1

In click event you can hide the column.

Each GridView column has the Visible and VisibleIndex properties. You can simply turn off the Visible property to hide a column and turn it back on to show it again.If you set this property to -1, a column becomes hidden as well.

void HideColumn(object sender, EventArgs e)
{
    colToHide.Visible=false;         
}

PrintPreview shows the same columns as the source grid. The columns to show are taken at the moment of generating a document. You can hide required columns by setting Visible to false, when calling the CreateDocument method of the VisualDataNodeLink .
