Forms Data Controls :: GridView To Excel Data Duplication - How To Stop It
Jan 15, 2010
I am new to ASP.NET but have had about a year of experience with VB.Net. Currently I am working on a webpage where I can download my inventory list from a GridView control to an excel spreadsheet. The routine is very straight forward however I cannot get it to stop duplication data in the spreadsheet. When I run my routine it inserts the gridview twice in the spreadsheet, the second one immediately to the right of the first table...
[code]....
It renders perfectly on the page by using the following commands:
[Code]....
I have tried a little bit of everything to stop the duplication and am completely stumped.

I populate a DetailsView from an ObjectDataSource that is coded in a class - meaning that the ods Select, Update, Insert and Delete are class methods. The selected record is set to come from a GridView.SelectedValue.
My problem is that when the page loads the code crashes. I am pretty sure I know why: the DetailsView is pulling from a class object and instead of using the existing class object it instansiates a new one which is empty.
Here is the details view code:
[Code]....
Here is the odsDetailsView_1:
[Code]....
As you can see from the code the odsDetailsView gets it's information from a class object "Match". The detailsview is not controlled by any code behind.

I'm getting duplicated rows of data showing up in my GridViews. I have two GridViews, each showing different data. I'm using SQL queries to retrieve the data from 2 database tables (1 query pulls from one table and the other query pulls from a second table, but references the first table in the WHERE clause). The GridViews were not duplicating data until after I added the Data Binding code to each GridView event handler and the button click event handler (outside of the GridView). I double checked my SQL queries by running them in TOAD and did not get any duplicated rows. So the issue is not with the SQL queries. It appears to be the GridViews causing it, or the Data Binding, or combination of those two, but I'm not sure what it is.Has anyone heard of or seen this? If needed, I can post my VB code and GridView code.

when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_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();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.

How can I display edit and new buttons without duplication in a detailsview control? This is a question from a past exam paper for 70-562. Part of the question is below:
"The company CIO assigns a task to you. According to his requirement, you must make sure that the users can insert and update content in the DetailsView1 control. Besides this, you have to prevent duplication of the link button controls for the Edit and New operations. At line 3, which code segment
should be inserted?"
