Data Controls :: Export GridView To Excel With Auto Generated Row Number (Row Index)
May 7, 2015
string attachment = "attachment; filename=Report.xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
GridView1.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
The above code exports gridview1 data to excel, but the requirement is export data with row no as first column in Excel. I tried to add row number in dataset that binding to gridview, when we sort data in gridview, row number are not in correct order.

I would like to inquire about the delete the data in gridview with automatic number parameter ..when I edit a field with auto parameter number, how do I delete a field that does not automatically sort ..ex:
1. ROBERT
2. EMILIA
3. JOSE
When I remove the column to 2 EMILIA, then display in gridview 1. ROBERT 3. JOSE.
Coding that I got when I remove emilia then display in gridview 1.ROBERT 2.JOSE .. (sequence automatically)
private void Bindemptydt() {
//Declare a datatable for the gridview
DataTable dt = new DataTable();
//Add Columns to the datatable
dt.Columns.Add("COLUMN");
dt.Columns.Add("TEXT");

I am currently working on a module in which I am creating an auto generated column gridview, and I have set the Auto generate edit button field to true. What happens now when I click the edit button The primary key field is turned in to edit mode which I want to restrict from being updated.
To restrict the same I have hard coded a template field which holds that column, But as I have set the AutoGenerateColumns Property to true the gridview automatically creates a duplicate field for holding the primary key column. For which I want to delete that particular column.
My Designer Code is:-

in page load I am binding the grid view.

I have a gridview which has autogenerate Columns Property "TRUE", and i'm dynamically binding this gridview with columns with sql database dataset. there is no data in sql but i am successful in showing blank gridview on form, now i want textboxes in gridview attached with each column, so i wrote code in RowDataBound which generates textbox automatically and assigns ID to each textbox, nw i want to insert that data from textbox to database but i'm not getting text which is entered in those textboxes, as i am accessing that textboxes using findcontrol and passing the id like gridview1_ctl03_text0. but i''m not getting any value from textbox?
In short i want to access auto generated textbox (with out any id predefined ) values from footer of gridview

I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.

I need to make a link for all the rows in one column of a gridview(VB .Net) where the grid has been auto-created from the data source. The link would simply point to another ASP details web page. The examples I have found have all been in C# and I don't quite follow them.

I need to export a gridview to excel and am having trouble with the layout. I found a number of good articles that explain the basic mechanics of the export. One simple approach that works is:
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
Response.Charset = ""
Response.ContentType = "application/vnd.xls"
Dim stringWrite As New System.IO.StringWriter()
Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
grdExcelExport.RenderControl(htmlWrite)
Response.Write(stringWrite.ToString())
Response.[End]()
My issue is that the gridview that appears on the screen with all of its added rows, hidden columns, and such does not show properly in Excel - the hidden columns from the header now show; there are missing data rows and so forth.
The RowDataBound event adds rows in the Header - these do not make it into Excel. The sql code does a GROUP BY WITH ROLLUP and the last total rows do not show in Excel, although the intermediate ones do. After my first DataBind of the table, I append 5 rows of special summary information which the RowDataBound processes correctly, but none of this goes to Excel.
So my wonderful Gridview on the screen becomes worthless in the transfer. How do I get my highly custom-formatted gridview into Excel??
