Forms Data Controls :: Updating Gridview After Export To Excel?
May 12, 2010
I have a page that has a gridview that stores the value of search parameteres in my page.
the search parameters are inserted in a table after the results are exported to excel(done through a seperate button).
Now the problem is once i hit the export to excel button, the gridview is not getting updated. I made sure that the entry is being made in database, but it in is not showing in grid immediately. The grid view is in updatepanel.
I am using Ajax ConfirmButtonExtender Control in GridView for Deleting the Record. I am also Exporting the GridData to Excel using Render Method. But when i click on the Export Button, i am getting below error Extender control 'confirmID' is not a registered extender control. Extender controls must be registered using RegisterExtenderControl() before calling RegisterScriptDescriptors(). Parameter name: extenderControl
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??
I have not done this before so pardin this question that I am sure has been asked before. I have a user that asks me to run queries each month and copy & paste the data into a spreadsheet I want to set up the queries in a web page for him to choose, enter the data in the parameters and either show the data in a gridview then export or just export to the spreadsheet direclty to the file name and location of his choice. Using C# Links or code samples would great.
I have a gridview that I need to export to Excel. Excel is not installed on the server, but I would like to put a template on the server so that when the user exports the data it will use the template and open the file on the user's local machine.To make things slightly more complex, I need to export the data to Sheet2 because Sheet1 needs to be a graph (thus the need for the template).I cannot use any third party software and I have no ability to modify anything on the server. This is used in a corporate environment on a shared server that I don't have any control over.
So I have a gridview that is sortable. I also have enabled it to export to excel. The problem is that it exports the original datasource and not the sorted data on the screen. What I need is when the export control is fired, the exact gridview or newly sorted gridview is sent to an Excel spreadsheet. Here what my excel export looks like:
I want ot export 4 Gridview contents to a Excel file. I got code from net and successfully export all 4 Gridviews to a single Excel file. The problem is, I want to export the Gridview to Excel with some minor changes. I have no idea about how to do it. I wish to make changes on the fly. The only idea I have is make another page that have 4 Gridviews with the changes I want and export it to Excel. But the user never view that page.The changes, I want to add in Excel file is, I want to change title of a Gridview field.

I am developing in .Net 4. I got a button to export grid view's data to excel, but one problem I faced is that the excel's rows height is very very 'short', I have to double click the row to expand it?I am not sure how can I set the height's property? I don see there is an option to do this.I got another version in .Net 3.5, same code though, but works perfect.
I have a 2008 c# application that displays data in a gridview. Two of the columns can contain text up to 500 characters. I have been able to handle these in the gridview by displaying the long text in a scrolling div tag. That works fine in the gridview, but when I export the gridview to excel, the row-height autofits to the large text fields, giving extremely tall rows. Any idea on how I can control the formatting to limit the row-height for the output excel spreadsheet? The approach I use for the export is described in
I have a GridView in my VB.Net 3.5 web app that contains a HyperLinkField. I have added a button to export all the GridView recs. It works fine, however, the HyperLinkField column comes into Excel as a hyperlink also. How do I prevent that?
