Print a Grid View

Question

Hi everyone I am new to C# and I require help printing the contents of a grid view on an aspx webpage. At present I have a print button placed on the page where the Grid View is positioned. This print button has been programmed via html. The current button prints the whole web page contents including the menu bar and the print button itself rather than the grid view only. Is it possible to only print a grid view on an aspx page? If so I would be extremely grateful if someone could guide me through the steps to achieve this in a simple yet effective way. I'm unsure whether the print command should be coded into the html page or the C# behind code. I welcome any feedback Many thanks.

yes using javascript you can easily print the content of the GridView. put the following javascript function on your head section function printItn() { var prtGrid = document.getElementById(' '); prtGrid.border = 0; var prtwin = window.open('' 'PrintGridViewData' 'left=100top=100width=1000height=1000tollbar=0scrollbars=1status=0resizable=1'); prtwin.document.write(prtGrid.outerHTML); prtwin.document.close(); prtwin.focus(); prtwin.print(); prtwin.close(); } and call this function on click of the button it will definitely help you out. If it helps you then please mark it as an accepted answer otherwise let me know i will send you the code.

Thank you I have added the code but it doesn't seem to change anything. No title is showing. The content of the grid view is controlled by drop down lists and is controlled via an sql data source. Could this be the reason as to why that code isn't enforcing a title?

on the databound event of the gridview you can do this protected void GridView1_DataBound(object sender EventArgs e) { GridViewRow row = new GridViewRow(0 -1 DataControlRowType.Header DataControlRowState.Normal); TableCell left = new TableHeaderCell(); left.ColumnSpan = GridView1.Columns.Count; left.Text = Print out of the Customer details +        ; left.Text = left.Text+Date: +DateTime.Now.ToString(); row.Cells.Add(left); ((Table)GridView1.Controls[0]).Rows.AddAt(0 row); }

Please ignore my previous reply I copied the code in the wrong place. I now have the print button working! If I want to add a title to the print page how would I do this? I pressume I need to add it somewhere between this code: Var prtwin = window.open( ''  'PrintGridViewData'  'left=100top=100width=1000height=1000tollbar=0scrollbars=1status=0resizable=1' ); prtwin.document.write(prtGrid.outerHTML); prtwin.document.close(); prtwin.focus(); prtwin.print(); prtwin.close(); }

Thank you for getting back to me so quickly. I have added the button code however when i run the program I get the following error Microsoft JScript runtime error: 'printItn' is undefined Below is the code which I pasted in from your reply. I also get rather a lot of errors within the aspx page including prtgrid prtwin and var are not a known CSS property name and  Missing a colon (':') between the property and value in the  :  declaration I'm not sure if i am getting the errors because I have pasted the code in the wrong place. function printItn() { var prtGrid = document.getElementById(' '); prtGrid.border = 0; var prtwin = window.open('' 'PrintGridViewData' 'left=100top=100width=1000height=1000tollbar=0scrollbars=1status=0resizable=1'); prtwin.document.write(prtGrid.outerHTML); prtwin.document.close(); prtwin.focus(); prtwin.print(); prtwin.close(); } .style20 {font-size: large;} Thank you for your reply sorry to keep bothering you with questions.

Thank you for your relpy! I have added the code to the header section of my javasrcipt but I am unsure how to recall that code on a button click. I pressume I have to recall the function prinItn () somehow? Also when copying the code a lot of errors appear such as prtwin is not a known CC property value. Thanks for your help/
