set button visibility in code behind aspx.net

How can I set in my button_Click event, visibility of button in gridView to false? All the time it give me an error:Compilation Error

Compiler Error Message: CS0103: The name 'btnTest' does not exist in the current context 

 <asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView2_RowDataBound">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="Button189" OnClick="Button189_Click" runat="server" Text="odzemi svez vrganj" />

                        <asp:Button ID="btnTest" runat="server" CommandName="odzemi" CssClass="button2" OnClick="btnTest_Click" Text="-" Width="100px" Font-Bold="True" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

Following is my button event from where i want to hide button inside gridview.

 protected void Button10_Click(object sender, EventArgs e)
 {
     btnTest.Visible = true;
     Button189.Visible = false;
 }

Use following code to set button visible property to True or False . The Button in gridview which will be clicked will act as sender. Doing so will give you the row id where the button is fired from and then you can find other controls and set your desired property on that particular row. 

protected void Button189_Click(object sender, EventArgs e)
 {
        Button Btn = sender as Button;
        GridViewRow gvRow = Btn.NamingContainer as GridViewRow;
        int rowId = gvRow.RowIndex;
        Button Button189 = GridView2.Rows[rowId].FindControl("Button189") as Button;
        Button btnTest = GridView2.Rows[rowId].FindControl("btnTest") as Button;
        Button189.Visible = false;
        btnTest.Visible = true;
 }

You need to loop through the gridview rows and find the control 

  foreach (GridViewRow row in grid.Rows)
   {
     if(row.RowType == DataControlRowType.DataRow)
      {
         var control =  ((Button)row.FindControl("btnTest"));
         if (control != NULL)
         {
             ((Button)control).Visible = false;
         }  
      }          
  }
