ASP.NET How to pass container value as javascript argument -

I am experimenting with a template on a text box.

I want to pass an argument to a JavaScript, an existing line index of a grid when a user clicks on it.

but

  onClick = 'setGridInEditMode (& lt;% # container. Result of record index%>); '/ & Gt;  

comes out as

  onClick = "setGridInEditMode (& amp; ###container.record index%>);"  

Is there a way to pass the container value for JavaScript?

Here's the markup in question.

  & lt; Cc1: Grid ID = "_trustgrid" runat = "server" folder style = "Styles / style_7" permission Dilling Records = "wrong" AllowSotting = "wrong" Allow PageSwapConclusion = "False" AllowGaganing = "Incorrect" AllowMultiardAditing = "True" auto generated column = "wrong" onupdateMand = "_trustgrid_update commmand" honorbind = "_trustgrid_rbind" & gt; & Lt; Columns & gt; & Lt; Cc1: Column AllowEdit = "true" permission by = "incorrect" header text = "edit" width = "130" run = "server" /> & Lt; Cc1: column datafield = "trustdocid" headerText = "trustdocid" width = "125" read-only = "wrong" allow = "false" TemplateId = "trustDocIDGridTemplate" /> & Lt; / Column & gt; & Lt; Templates & gt; & Lt; Cc1: GridTypePlat ID = "TrustDoDidGridGrammet Template" control id = "TB1" runat = "server" & gt; & Lt; Template & gt; & Lt; ASP: Text Box ID = "TrustDocuedTexbox" Runat = "Server" visible = "true" text = '& lt;% # container.value% & gt;' OnClick = 'setGridInEditMode (& lt;% # Container.Record Index% & gt;);' / & Gt; & Lt; / Template & gt; & Lt; / CC1: GridTemplate & gt; & Lt; / Templates & gt; & Lt; / CC1: Grid & gt; I used to call the second Darin to use the inefficient JavaScript.

However, Does not answer your question why this is being done by ASP.Net.

The reason for it

  onClick = "setGridInEditMode (& amp; ltd;% # container; Records index%>;);"  

That's because the server does not interfere directly in the database in the database for control properties. It means, only property = "& lt;% # ...% & Gt; " is allowed.

So in your case, you have to say what you want to do a roundabout fashion (though I personally think it is a bit clearer and more accomplished):

  onClick = '& lt;% # String.Format ("setGridInEditMode ({0});", container. Record Indexes% & gt;  

(See your single and double quotes!)

This limit applies to only server controls and their properties. It does not apply to the nested textual content of a server control (such as the templates or the bodies of panels) nor is there any other plain HTML used, which is probably why you have not seen it before.
