Ok, I can see from your example that only Paste the cells in both TextAreas and check the results by clicking on each button. 'Querying the Clipboard data (IE Only): ' + enc_clipboard 'Querying the Ext.NET textarea: ' + enc_extnet_field + '' + 'Querying the HTML5 textarea: ' + enc_aspnet_field + '' + Var enc_clipboard = window.encodeURIComponent(('text')) The getData option here is returning nothing for me when I paste in a file (ex: myfile.jpg). Im trying to write a jquery script that gets the data out of an image file thats being copied and pasted and then turns it into a DataURL. Var enc_extnet_field = window.encodeURIComponent(extnet_field) Using clipboardData.getData for image files.
Var enc_aspnet_field = window.encodeURIComponent(aspnet_field) Here the values are already provided without the CR (\r) characters Var form = document.getElementById('Form1') "Querying the Clipboard data (IE only): " + clipboard + "", "Querying the Ext.NET textarea: " + extnetGetValue + "" + In Firefox, Opera, Google Chrome and Safari, use the execCommand method with the Paste. In Internet Explorer, use the setData method to set and the clearData method to clear the contents of the clipboard. "Querying the ASPNET textarea from JavaScript : " + textArea_js + "" + method (clipboardData) Browser support: Retrieves the specified formatted data from the clipboard.

Here's your example reviewed to explore those features.
#Window clipboarddata getdata code#
If you really want code behind to see the CRLF line endings you will have to replace the \n occurrences to Environment.NewLine (or \r\n) in code behind or by overriding (). The "cleanup" happens either during paste or when fetching the values with JavaScript.Īn ordinary ASPNET form submit surprisingly seems to convert the line breaks to CRLF - or keep them with CRLF. The returned value for each field though, has just LF as line breaks. When Ext.NET is preparing a form to be submitted, it traverses the form elements to get their values and encode as URI string for submission. At least Google Chrome does not support it at all.Īs for why the CR character (\r) is stripped away from the string, that's something inherent from the browsers and JavaScript.
#Window clipboarddata getdata portable#
Hello gets the problem because ('text') is not portable across browsers. Public void cmdWindowAlternativeCopyMethodContinue2_DirectClick(object sender, DirectEventArgs e) String CLIPBOARDDATA = txtAlternativeAreaCLIPBOARDDATA.Text Public void cmdWindowAlternativeCopyMethodContinue_DirectClick(object sender, DirectEventArgs e) Copy to Clipboard JavaScript // Microsoft Internet Explorer only // Manipulating the system clipboard in JavaScript // Read more at: // http. Protected void Page_Load(object sender, EventArgs e) It is not important that it is a textarea. How can I preserve \r\n copying the clipboard in a ext.net control. With ('Text') you can see that each line ends with \r\n In DATA_CLIPBOARD I lose characters \r at the end of each line and leaves only \n It is actually outdent content and manually i have to indent it to view bullets. document.getElementById(myGridID).If I paste some cells (eg, 5 rows and 5 columns) from Excel in the textArea of my example When i copy and paste content from word document to even online summer note editor it does not display bullets and numbers in any browser. This was sufficient for my deployment, but for others, it may be worthwhile to launch a confirm window to verify intention. I then added the listener below which essentially determined if the content was tab-delimited and treated it as a "Paste from Excel" whereas it treated other data layouts as a standard "Paste". If window.clipboardData is undefined the user received a message saying that you must use the standard CTRL+V paste in this browser.
Users previously used a custom right-click menu to access "Paste From Excel" functionality to replace content in an editable grid with tab-delimited content from the clipboard. As Kaiido noted, it is not possible to get at the pasted content outside of the paste event in Edge (and Chrome for that matter).
