ImageButton Visibility not getting changed in aspx.cs page - asp.net

Question

I'm using a gridview to display some data. There is an image button to display a flag. Within the GridView RowDataBound Event i'm changing the visibility of that button. But the visibility didn't get changed. Here is the code:
bool status = true; // getting this via dataset
ImageButton imgTest = (ImageButton)e.Row.FindControl("ImageButton1");
imgTest.Visible = status;
But still visibility is false.
EDIT:
Here is my HTML Code;
<asp:GridView runat="server" ID="gvScheduleView" DataKeyNames="ControlID,IsPrinted, PrintDate, DueDate"
Width="100%" ShowHeader="true" ShowFooter="true" AutoGenerateColumns="false"

Answer 1

<div id="DivBtnImgCopy" runat="server" visible = "<% =ShowHideButton() %>">
<asp:ImageButton ID="ibEditProps" runat="server"ImageUrl="~/common/images/icons/building_edit.png"
OnClick="ibEditProps_click"CommandArgument='<%# Eval("ControlID") %>' CommandName='<%# Eval("Type") %>' ToolTip="Edit Properties" />
</div>
Code Behind
protected bool ShowHideButton()
{
bool bStatus = false;
try
{
if (sCondition == "false")
{
bStatus = false;
}
else if (sCondition == "true")
{
bStatus = true;
}
return bStatus;
}
catch { }
