I'm exporting data to an excel sheet from the ojects list. The data is exporting to excel sheet well, but I'm unable to see the grid format for the data. The data is looking with out the rows and columns lines.I think I'm missing to set some property or somethnig ehwn exporting.
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??
Iam using the VS 2008 Report Viewer Control in my project . Iam using the Sub reports in many cases. when ever i export such reports containing sub reports to Excel format which is the major client requirement in our project , the exported excel file shows 'Sub Reports within table / Matrix cells are ignored. If not possible in reporting service then is there any other way to get data in excel format?
I want read the data from Excel file and bind it to gridview.but before that i want to set "Column data format as text" for few columns or whole worksheet in programatically.In excel sheet we can set the column data format as text.but i want to do that in programatically(codebehind).
I want to import a spreadsheet into SQL. The import/export wizard forces Column A to be a double. In Excel, the column is formatted as text. When I try to convert from double to text/varchar/nvarchar, the import process fails. Why can't I convert a number to text in SQL?
I am able to save excel sheet from GridView perfectly. However, I need to add one custom column, which will be URL of a file on sever, I am not allowed to add URLs directly in the table (as per company's development policies). I tried pulling URL from web.config however I am not sure where to add that in the following code
I have been searching the internet for a solution to this for hours. I have tried all of the following methods to set the column width on my GridView control:
1. <asp:TemplateField HeaderText="ColumnHeader" ItemStyle-Width="100px"> 2. <ItemStyle Width="100px" Wrap="False" /> 3. GridView.Columns[0].ItemStyle.Width = 100 both on the PageLoad event and, out of desperation, on the RowDataBound event.
I have tried these settings by themselves and in combination. I have also experimented with different CSS width settings for the GridView and its containing <div> (including none) to no avail. The GridView columns are always equally spaced and wrap the row description text in the first column in a rather ugly fashion. As this needs to be fixed for a presentation to a client on Monday, I would be eternally grateful to anyone who could point me in the right direction.
I'm creating a ListView and have been unable to format column widths. After much research I have found that the width property of the <asp:Label doesn't work. I'm using
I test the FormView by changing the width property and it doesn't affect the width of the column. The <th control in the layout template has a width="60" that appears to be working. If I remove the <asp:label from the <td in the Item and AlternateItem templates, the width is set to 60. When I paste the <asp:label back into the <td, the width of the column increases to about 200px even though the width is set to 10. I set the backcolor to Aqua to see the label and it is about 200 px widt.
to setting the length of the lblContol in the template but no matter what I do the column size automatically increases beyond my fixed size to meet the size of the longest cell in the bound datatable.
anybody working on data exporting? I've 4 tables in my sql server database. I want to export these 4 tables data into one excel file in different sheets with column names.
I am facing a problem with Gridview control. I have created a Gridview1 which is having 3 button column that has been added at design time and some column can be added through the Datatable at runtime. At Design time GridView1 has 3 button column
At Runtime I do GridView1.Datasource=dt; //Now my gridview is having 7 columns i.e. 4 more columns added through datatable.
I can easily display that GridView1 on webpage but I dont want to show some column that I added through Datatable to the user.
When I try to hide that column, I get error like Index out of bound exception but when I hide button column I can able to do that easily.
I am having a DataGridView in that having 4 columns I need to bind 1 hyperlink column to the webservice which returns me DisplayText and Navigation URL.
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?
I am using a datalist to display data from a database.Except for 1 column all the other column values are getting repeated so I am hiding all the other column values when the datalist repeats itself.However, the unique column value is not getting rendered properly because there are many line breaks in between.I am not using any web control to display the static text and I am not sure if that would help.I just want to improve the final display so that the datalist looks consistent.I am attaching my code.
