How to pass bind or eval arguments with the client function "OnClientClicking"

Question

I meet about problem to pass arguments to the client-side event OnClientClicking.

I tried to use the String.Format () function, but it does not work.

Do you have an idea for a workaround to send parameter linked with OnClientClicking?

Code asp :

<telerik:RadButton ID="bnt_meetingDelete" runat="server" OnClientClicking="<%# string.Format("confirmCallBackFn('{0}');",Eval("MeetingID")) %>" Image-ImageUrl="~/image/icone/delete-icon.png" Image-IsBackgroundImage="true" Width="21" Height="21" telerik:RadButton>

Error IIS:

Parser Error 
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. 

Parser Error Message: The server tag is not well formed.

I tried with controller [asp: ImageButton ]. And is the same mistake

Answer 1

Change double quote to single quote from

OnClientClicking="<%#string.Format("confirmCallBackFn('{0}');",Eval("MeetingID")) %>"

to

OnClientClicking='<%#string.Format("confirmCallBackFn('{0}');",Eval("MeetingID")) %>'

Or remove your string.Format and use like this

OnClientClicking='<%# "confirmCallBackFn("+ Eval("MeetingID") + ");" %>'

Answer 2

try OnClientClicking='<%# Eval("MeetingID", "confirmCallBackFn({0})") %>'

Answer 3

Use this format

OnClientClick='<%# "text1" + Eval("value") + "text2" %>'

Make you you escape the \" correctly for it to work correctly:

OnClientClick='<%# "return confirm(\"Are you sure you want to unlock this user " + Eval("Lockout") + "?\");" %>'/>

It will be look like this after it rendered:

onclick="return confirm("Are you sure you want to unlock this user True?");"
