ImageButton Visibility not getting changed in aspx.cs page

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"
            OnRowDataBound="gvScheduleView_rowDataBound" Height="100%" CssClass="removePaddingRight">
            <Columns>
                <asp:TemplateField HeaderText="Type" HeaderStyle-HorizontalAlign="center" ItemStyle-HorizontalAlign="Center">

yes. I have hard corded the value to true. Still the issue is there. Seems its a framework issue. — Aruna, Jan 02 '14 at 06:27
Try setting `visibility=false` to the image button and then check. — MusicLovingIndianGirl, Jan 02 '14 at 06:44

<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 { }
    }

This gives "'System.Boolean' from its string representation '<% =ShowHideButton() %>' for the 'Visible' property." – Aruna Jan 02 '14 at 07:01
I can't get you. Please elaborate – Vignesh Kumar A Jan 02 '14 at 07:09
visible = "<% =ShowHideButton() %>" throws an error. it has to be visible = "<% =bool.Parse(ShowHideButton()) %>". But my issue is still there. – Aruna Jan 02 '14 at 07:22
