解决Grid的navigationurl的编码问题_walkingtec grid url-优快云博客

本文介绍了一个ASP.NET中GridView控件HyperLinkField导航URL的编码问题及其解决方案。通过自定义的方法HyperLinkFieldUrlEncodeHack，确保了链接正确地进行URL编码，避免了因特殊字符导致的链接错误。

protected void HyperLinkFieldUrlEncodeHack(GridView gridView, GridViewRowEventArgs e, int index, string defaultValue)
    {
        HyperLink hyperLink = (HyperLink)e.Row.Cells[index].Controls[0];
        HyperLinkField hyperLinkField = (HyperLinkField)gridView.Columns[index];
        if (!string.IsNullOrEmpty(hyperLinkField.DataNavigateUrlFormatString))
        {
            string[] dataUrlFields = new string[hyperLinkField.DataNavigateUrlFields.Length];
            for (int j = 0; j < dataUrlFields.Length; j++)
            {
                object obj = DataBinder.Eval(e.Row.DataItem, hyperLinkField.DataNavigateUrlFields[j]);
                string value = Convert.ToString(obj);
                if (string.IsNullOrEmpty(value))
                    value = defaultValue;
                dataUrlFields[j] = HttpUtility.UrlEncode(value);
            }
            hyperLink.NavigateUrl = string.Format(hyperLinkField.DataNavigateUrlFormatString, dataUrlFields);
        }
    }

    protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            HyperLinkFieldUrlEncodeHack(GridView1, e, 4, "总计");
        }
}
