    <p>I'm trying to export a GridView to Excel and I have a column with a series of numbers like 1245333325364. When I run the query for the GridView I can see the complete number but when I export to excel all I see is 1.00133E+12 on that column. I know I can have the user change this in excel but not all files are being open after export they just save it straight into a directory. I will really like to change the column's format in the export process rather than having the user do it before they save the file. I'm performing the export in C# any help will be really appreciate.</p> <p>The code I'm using to export the GridView is like so:</p> <pre><code> protected void exporttoexcel_Click(object sender, EventArgs e) { string date = DateTime.Now.ToString("MM-dd-yyyy"); PrepareGridViewForExport(GridView1); Response.Clear(); Response.Buffer = true; Response.AddHeader("content-disposition", "attachment;filename=" + date + "_" + CHROUT.Text + "_Trailer_" + TRAILER.Text); Response.Charset = "''"; Response.ContentType = "application/vnd.ms-excel"; StringWriter sw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(sw); GridView1.AllowPaging = false; GridView1.DataBind(); GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF"); GridView1.HeaderRow.Cells[0].Style.Add("width", "105px"); GridView1.HeaderRow.Cells[0].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[1].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[2].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[3].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[4].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[5].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[6].Style.Add("background-color", "#CCCCCC"); GridView1.HeaderRow.Cells[7].Style.Add("background-color", "#CCCCCC"); for (int i = 0; i &lt; GridView1.Rows.Count; i++) { GridViewRow row = GridView1.Rows[i]; row.BackColor = System.Drawing.Color.White; row.Attributes.Add("class", "texmode"); if (i % 2 != 0) { row.Cells[0].Style.Add("background-color", "#f0f0f0"); row.Cells[1].Style.Add("background-color", "#f0f0f0"); row.Cells[2].Style.Add("background-color", "#f0f0f0"); row.Cells[3].Style.Add("background-color", "#f0f0f0"); row.Cells[4].Style.Add("background-color", "#f0f0f0"); row.Cells[5].Style.Add("background-color", "#f0f0f0"); row.Cells[6].Style.Add("background-color", "#f0f0f0"); row.Cells[7].Style.Add("background-color", "#f0f0f0"); } } GridView1.RenderControl(hw); //style to format numbers to string string style = @"&lt;style&gt; .text { mso-number-format:\@; } &lt;/style&gt;"; Response.Write(style); Response.Output.Write(sw.ToString()); Response.Flush(); Response.End(); } </code></pre>

    2. COIf by expand you mean making the cell's width bigger, the answer is no. I still show the scientific format.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
