c# - Show Hide using Javascript on a control, inside a ASCX control in a gridview. (ASP.NET + Javascript) -

-

i have written web usercontrol (ascx). inside, there panel want show/hide on click of hyperlink inside usercontrol.

normally, easy doing (the onclick attribute added hyperlink on prerender):

 var paneltoshow = document.getelementbyid('<%=panelinvoicehasbeencreated.clientid %>');      if (paneltohide != null) {         paneltohide.style.display = 'none';     }

but because ascx control held within gridview, above assess controls (of there many in gridview) name 'panelinvoicehasbeencreated'. time work when there 1 row in gridview. currently, existing code, if click hyperlink in row, shows/hides panel in bottom row of gridview!

therefore, question how actual, unique id need show/hide on correct control in correct row??????

thanks in advance.

you can @ rowdatabound event of gridview

write below code @ gridview rowdatabound event

var usercontrol1=(usercontrol)e.item.findcontrol("usercontrol1"); var hyperlink1=(hyperlink)usercontrol1.findcontrol("hyperlink1"); var panelinvoicehasbeencreated=(panel)usercontrol1.findcontrol("panelinvoicehasbeencreated");  hyperlink1..attributes.add("onclick", "javascript:return showhidepanel('"+ panelinvoicehasbeencreated.clientid +"')");

and java script function @ aspx page should this

<script type="text/javascript"> function showhidepanel(panelid) {  var paneltoshow = document.getelementbyid('panelid');      if (paneltohide != null) {         paneltohide.style.display = 'none';     } return false;  } </script>
