I have two gridviews on a page. When I click on Button3 it exports gridview data to excel perfectly.
but when I click on Button5 it exports data of gridview to excel and in excel file contains only:
<style> .textmode { } </style><div>
here is my c# code:
protected void Button3_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=ExportFile.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
using (StringWriter sw = new StringWriter())
{
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.AllowPaging = false;
GridView1.Columns[0].Visible = false;
GridView1.Columns[1].Visible = false;
//GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
this.GridView1.DataBind();
GridView1.HeaderRow.BackColor = Color.White;
foreach (TableCell cell in GridView1.HeaderRow.Cells)
{
cell.BackColor = GridView1.HeaderStyle.BackColor;
}
foreach (GridViewRow row in GridView1.Rows)
{
row.BackColor = Color.White;
foreach (TableCell cell in row.Cells)
{
if (row.RowIndex % 2 == 0)
{
cell.BackColor = GridView1.AlternatingRowStyle.BackColor;
}
else
{
cell.BackColor = GridView1.RowStyle.BackColor;
}
cell.CssClass = "textmode";
}
}
GridView1.RenderControl(hw);
//style to format numbers to string
string style = #"<style> .textmode { } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
}

I am trying to print a text " This is my customer information" into an Excel file before writing GridView data to Excel. This text should be in top and remaining data should display below this text.
Can anyone help me? How can I do it? Please check my current code. This code just writes my GridView data to an Excel file.

I have developed an excel sheet using c# gridview. How do I add a header row and set column names via code. This is my current code...
protected void ExportToExcel1(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";
using (StringWriter sw = new StringWriter())
{
HtmlTextWriter hw = new HtmlTextWriter(sw);
//To Export all pages
GridView1.AllowPaging = false;
bindgrid();
GridView1.HeaderRow.BackColor = Color.White;
foreach (TableCell cell in GridView1.HeaderRow.Cells)
{
cell.BackColor = GridView1.HeaderStyle.BackColor;
}
foreach (GridViewRow row in GridView1.Rows)
{
row.BackColor = Color.White;
foreach (TableCell cell in row.Cells)
{
if (row.RowIndex % 2 == 0)
{
cell.BackColor = GridView1.AlternatingRowStyle.BackColor;
}
else
{
cell.BackColor = GridView1.RowStyle.BackColor;
}
cell.CssClass = "textmode";
}
}
GridView1.RenderControl(hw);
//style to format numbers to string
string style = #"<style> .textmode { } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
}
I have the code below that generates an excel file when clicked. the code runs fine the formatting of colors is fine. The grid view has data with leading zeros that are not showing in excel along with long numbers "106638660952840428" which show up as 1.06639E+17 with a value of 106638660952840000 so it loses its last four digits as well. I have tried several ways to export all with the same results. I am doing it this way to have the chance at formatting the cells individually.So the question is does anyone know how to dynamically change the format so these problems do not occur? Another thing to add is that the grid-view in a web browser does display the data correctly.
protected void LinkButton6_Click(object sender, EventArgs e)
{
Iframe1.Attributes.Add("src", "blank.aspx");
if (CheckBox5.Checked || CheckBox6.Checked)
{
dt = (DataTable)Cache["dtable"];
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=BemisInventory.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
using (StringWriter sw = new StringWriter())
{
HtmlTextWriter hw = new HtmlTextWriter(sw);
//To Export all pages
GridView1.AllowPaging = false;
GridView1.DataSource = dt;
//GridView1.PageIndex = 0;
GridView1.DataBind();
GridView1.HeaderRow.BackColor = Color.White;
foreach (TableCell cell in GridView1.HeaderRow.Cells)
{
cell.BackColor = Color.White;//GridView1.HeaderStyle.BackColor;
}
foreach (GridViewRow row in GridView1.Rows)
{
row.BackColor = Color.White;
foreach (TableCell cell in row.Cells)
{
if (row.RowIndex % 2 == 0)
{
cell.BackColor = Color.White;
}
else
{
cell.BackColor = Color.White; //GridView1.RowStyle.BackColor;
}
cell.CssClass = "textmode";
}
}
GridView1.RenderControl(hw);
//style to format numbers to string
string style = #"<style> .textmode { } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
}
}
Fixed by adding: string style = #" .textmode { mso-number-format:\#; } "; comes up with warnings but all data is there.
I am exporting data grid view to an excel sheet, and it works.
There are 10 columns in grid view, but I want to show only 5 columns in the excel sheet.
How can I solve this?

{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=ActualsAndBudgets.xls");
Response.Charset = "";
Response.ContentType = "application/ms-excel";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvdetails.AllowPaging = false;
fillgrid();
gvdetails.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
gvdetails.AllowPaging = true;
fillgrid();
}
public override void VerifyRenderingInServerForm(Control control)

You can try the code below:
protected void ConvertToExcel_Click(object sender, System.EventArgs e)
{
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("content-disposition", "attachment;filename=ContactMailingAddress.xls");
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
ContactMailingView.AllowPaging = false;
ContactMailingView.DataBind();
//Apply style to Individual Cells
ContactMailingView.HeaderRow.Cells(0).Style.Add("background-color", "yellow");
ContactMailingView.HeaderRow.Cells(1).Style.Add("background-color", "yellow");
ContactMailingView.HeaderRow.Cells(2).Style.Add("background-color", "yellow");
ContactMailingView.HeaderRow.Cells(3).Style.Add("background-color", "yellow");
ContactMailingView.HeaderRow.Cells(4).Style.Add("background-color", "yellow");
for (int i = 0; i <= ContactMailingView.Rows.Count - 1; i++) {
GridViewRow row = ContactMailingView.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", "#C2D69B");
row.Cells(1).Style.Add("background-color", "#C2D69B");
row.Cells(2).Style.Add("background-color", "#C2D69B");
row.Cells(3).Style.Add("background-color", "#C2D69B");
row.Cells(4).Style.Add("background-color", "#C2D69B");
}
}
ContactMailingView.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();
}
I took it from my post in dotNetFromManila blog
Hope it helps you.
Use this code may help. and must add iTextSharp dll in your project.
