        GridView1.AllowPaging = false;

        // Re-Bind data to GridView 

        using (CompMSEntities1 CompObj = new CompMSEntities1())
        {
            Start = Convert.ToDateTime(txtStart.Text);
            End = Convert.ToDateTime(txtEnd.Text);

            GridViewSummaryReportCategory.DataSource = CompObj.SP_Category_Summary(Start, End);
            SP_Category_Summary_Result obj1 = new SP_Category_Summary_Result();

            ExportTable.Visible = true;
        }

        //Change the Header Row back to white color

        GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");


       GridView1.Style.Add(" font-size", "10px");




        //Apply style to Individual Cells

        GridView1.HeaderRow.Cells[0].Style.Add("background-color", "green");

        for (int i = 1; i < GridView1.Rows.Count; i++)

            GridViewRow row = GridView1.Rows[i];

            //Change Color back to white

            row.BackColor = System.Drawing.Color.White;

            //Apply text style to each Row

        //    row.Attributes.Add("class", "textmode");

            //Apply style to Individual Cells of Alternating Row

            if (i % 2 != 0)

        GridView1.RenderControl(hw);

        //style to format numbers to string

        string style = @"<style> .textmode { mso-number-format:\@; } </style>";

        Response.Write(style);
        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();
    }

Answer 3

对于打印，您可以使用CSS中的@media print { }块指定特殊样式，并在浏览器中手动启动打印或在JavaScript中调用window.print()。

要导出到Excel，您可以使用，例如http://closedxml.codeplex.com/。

要导出为PDF，您可以使用http://sourceforge.net/projects/itextsharp/。

{

    if (RadioButtonList1.SelectedIndex == 0)

    {

        GridView1.ShowHeader = true;

        GridView1.GridLines = GridLines.Both;

        GridView1.AllowPaging = false;

        GridView1.DataBind();

    }

    else

    }



    ChangeControlsToValue(GridView1);

    hForm.RenderControl(hTextWriter);



    // Write below code to add cell border to empty cells in Excel file

     StringBuilder sBuilder = new StringBuilder();
