Data Controls :: Disabling Or Hiding Export To Excel LinkButton If GridView Is Empty
Aug 22, 2012
disable linkbutton if gridview is empty in child pages. I have a Export to Excel LinkButton in master page and in child page I have textbox wherein I pass the input based on which the gridview loads. When the child page loads the Export linkbutton should be disabled. After entering the input in textbox on click of the button the gridview will be loaded wherein now the Export linkbutton should be enabled to export to excel.
I need to be able to hide or disable a multitude of items (detailsviews, gridviews) when an SqlDataSource returns no rows. So if the page is reposted and no rows are selected, all the controls would be disabled.
I have a project in vb with a gridview in a multiview and i want to save in a workbook excel the gridview displayed data. I have read many articles but in the end i have downloaded the code from URL...and i adapted for my code.

How can I export data from a Gridview to excel and once exported the data should be formatted in right to left (arabic) manner. How can I achieve this?

I have a problem with exporting two gridviews (main and nested gridview) to Excel fromat using ClosedXML (XLWorkbook). I read tutorial on aspsnippets and it works fine for main gridview.My code:
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 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 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.
I am having a bounded gridview through a database table. I am not showing all table's colum. there are 20 columns in databse table, but in gridview i am shoing only 5 coulmns.
Now I have button on the form on this button's click I can export all data i.e. whatever gridview showing means only 5 columns. But i need to export all 20 columns data to excel sheet.
How can I do that. (I can not show all 20 columns in gridview[this is requirement])
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.
