Code behind Page

Here I will explain how to solve the problem Control 'gvdetails' of type 'GridView' must be placed inside a form tag with runat=server during export of gridview to excel or word or csv using asp.net.
To solve this problem I have added one overriding function VerifyRenderingInServerForm event in code behind it solves my problem.

public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}

protected void OnPaging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
}

protected void btnExportWord_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.doc");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-word ";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.DataBind();
GridView1.RenderControl(hw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
//Excel Foramat
protected void btnExportExcel_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;

Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);

GridView1.AllowPaging = false;
GridView1.DataBind();

//Change the Header Row back to white color
GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");

//Apply style to Individual Cells
GridView1.HeaderRow.Cells[0].Style.Add("background-color", "#507CD1");
GridView1.HeaderRow.Cells[1].Style.Add("background-color", "#507CD1");
GridView1.HeaderRow.Cells[2].Style.Add("background-color", "#507CD1");
GridView1.HeaderRow.Cells[3].Style.Add("background-color", "#507CD1");

for (int i = 0; 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)
{
row.Cells[0].Style.Add("background-color", "#EFF3FB");
row.Cells[1].Style.Add("background-color", "#EFF3FB");
row.Cells[2].Style.Add("background-color", "#EFF3FB");
row.Cells[3].Style.Add("background-color", "#EFF3FB");
}
}
GridView1.RenderControl(hw);

//style to format numbers to string
string style = @"";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
//PDF Format
protected void btnExportPDF_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.DataBind();
GridView1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
}
//CSV format
protected void btnExportCSV_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.csv");
Response.Charset = "";
Response.ContentType = "application/text";

GridView1.AllowPaging = false;
GridView1.DataBind();

StringBuilder sb = new StringBuilder();
for (int k = 0; k < GridView1.Columns.Count; k++)
{
//add separator
sb.Append(GridView1.Columns[k].HeaderText + ',');
}
//append new line
sb.Append("\r\n");
for (int i = 0; i < GridView1.Rows.Count; i++)
{
for (int k = 0; k < GridView1.Columns.Count; k++)
{
//add separator
sb.Append(GridView1.Rows[i].Cells[k].Text + ',');
}
//append new line
sb.Append("\r\n");
}
Response.Output.Write(sb.ToString());
Response.Flush();
Response.End();
}

Check dot net core framework version in my PC Or System

 Open My Computer → double click "C:" drive → double click "Windows" → double click "Microsoft.NET" → double click "Framework" → Inside this folder, there will be folder(s) like "v1.0.3705" and/or "v2.0.50727" and/or "v3.5" and/or "v4.0.30319". Your latest .NET version would be in the highest v number folder, so if v4.0.30319 is available that would hold your latest .NET framework. However, the v4.0.30319 does not mean that you have the .NET framework version 4.0. The v4.0.30319 is your Visual C# compiler version, therefore, in order to find the .NET framework version do the following. Go to a command prompt and follow this path: C:\Windows\Microsoft.NET\Framework\v4.0.30319 (or whatever the highest v number folder) C:\Windows\Microsoft.NET\Framework\v4.0.30319 > csc.exe Output: Microsoft (R) Visual C# Compiler version 4.0.30319.17929 for Microsoft (R) .NET Framework 4.5 Copyright (C) Microsoft Corporati...

ASP.NET Routing

ASP.NET routing enables you to use URLs that do not have to map to specific files in a Web site. Because the URL does not have to map to a file, you can use URLs that are descriptive of the user's action and therefore are more easily understood by users. The ASP.NET MVC framework and ASP.NET Dynamic Data extend routing to provide features that are used only in MVC applications and in Dynamic Data applications. For more information about MVC, see ASP.NET MVC 3 . For more information about Dynamic Data, see ASP.NET Dynamic Data Content Map . In an ASP.NET application that does not use routing, an incoming request for a URL typically maps to a physical file that handles the request, such as an .aspx file. For example, a request for http://server/application/Products.aspx?id=4 maps to a file that is named Products.aspx that contains code and markup for rendering a response to the browser. The Web page uses the query string value of id=4 to determine what type of c...
