动态删除GridView指定列

方法一：

 protected void Button2_Click(object sender, EventArgs e)
    {
        this.GridView1.Columns.RemoveAt(1);
        this.GridView1.DataSource = GridViewDataSource();
        this.GridView1.DataBind();
    }

方法二：

protected void Button1_Click(object sender, EventArgs e)

{

//GridView1.Columns.RemoveAt(2);//column index

GridView1.Columns.RemoveAt(GetIndex(GridView1, "ProductName"));

GridView1.DataBind();

}

public static int GetIndex(GridView grd, string fieldName)

{

for (int i = 0; i < grd.Columns.Count; i++)

{

DataControlField field = grd.Columns[i];

//BoundField bfield = field as BoundField;

HyperLinkField hfield = field as HyperLinkField;

//if (bfield != null && bfield.DataField == fieldName)

// return i;

//if (hfield != null && hfield.DataTextField == fieldName)

if (hfield != null && hfield.HeaderText == fieldName)return i;

}

return -1;

}
