Gridview导出的问题与图像一起出色

问题描述

我有一个gridview，其中包含两个列中的进度条和图像。当我尝试导出gridview整个页面正在导出而不是只导出gridview。如何只导出网格视图以及进度条和图像而不是整个页面？

I have a gridview which contain progress bar and image in two of its columns. when i try to export the gridview entire page is being exported instead of only gridview. How to export only grid view along with progressbar and image instead of entire page?

推荐答案

public static void PrepareGridViewForExport(Control gridView)
    {
        for (int i = 0; i < gridView.Controls.Count; i++)
        {
            //Get the control
            Control currentControl = gridView.Controls[i];
            if (currentControl is LinkButton)
            {
                gridView.Controls.Remove(currentControl);
                gridView.Controls.AddAt(i, new LiteralControl((currentControl as LinkButton).Text));
            }
            else if (currentControl is ImageButton)
            {
                gridView.Controls.Remove(currentControl);
                gridView.Controls.AddAt(i, new LiteralControl((currentControl as ImageButton).AlternateText));
            }
            else if (currentControl is HyperLink)
            {
                gridView.Controls.Remove(currentControl);
                gridView.Controls.AddAt(i, new LiteralControl((currentControl as HyperLink).Text));
            }
            else if (currentControl is DropDownList)
            {
                gridView.Controls.Remove(currentControl);
                gridView.Controls.AddAt(i, new LiteralControl((currentControl as DropDownList).SelectedItem.Text));
            }
            else if (currentControl is CheckBox)
            {
                gridView.Controls.Remove(currentControl);
                gridView.Controls.AddAt(i, new LiteralControl((currentControl as CheckBox).Checked ? "True" : "False"));
            }
            if (currentControl.HasControls())
            {
                // if there is any child controls, call this method to prepare for export
                PrepareGridViewForExport(currentControl);
            }
        }
    }

和导出按钮点击事件



电话

call

PrepareGridViewForExport(gridView1);

然后导出excel代码
