Question

我正在使用gridview来显示一些数据。有一个图像按钮显示标志。在GridView RowDataBound事件中，我正在改变该按钮的可见性。但是能见度没有改变。这是代码：

bool status = true; // getting this via dataset
ImageButton imgTest = (ImageButton)e.Row.FindControl("ImageButton1");
imgTest.Visible = status;

但仍然可见度是错误的。

修改

这是我的HTML代码;

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>

背后的代码

protected bool ShowHideButton()
    {
        bool bStatus = false;
        try
        {
            if (sCondition == "false")
            {
                bStatus = false;
            }
            else if (sCondition == "true")
            {
                bStatus = true;
            }
            return bStatus;
        }
        catch { }
    }

ImageButton在aspx.cs页面中不会更改可见性
