C# parameters in a javascript function

Question

I need to call a JS function with a C# parameter.

This is inside a HTML table.

    <td onclick="OpenWindow(<%= cbYear.SelectedValue%>, 2);return false;">
        &nbsp;
    </td>

The JS function:

function OpenWindow(annee, mois) {

    //Call existing global function to obtain a reference to the window manager
    var oManager = GetRadWindowManager();
    //Show a particular existing window
    oManager.open(null, "RadWindow1");
}

the problem is simply it does not work anymore with paramaters( it works perfectly without)... Does anyone know why, thanks in advance

the produced source is this : <td onclick="OpenWindow(<%= cbYear.SelectedValue%>, 2);return false;">0</td> — user1173169

this looks to me like it would work. What error are you getting, what type is cbyear.selectedvalue, what have you tried, etc? — Phillip Schmidt

The only time I normally see something like this is if the HTML control (in this case the <td>) is set to runat="server" — freefaller

The only time I've seen the <%=...%> be rendered into the browser is when the HTML control (in this case <td>) is turned into a server-side control using the runat="server" attribute.

IF this is the case, I would suggest that you place the following in your code-behind file (assuming you have a code-behind), and remove the onclick from the markup

myTdCell.Attributes("onclick") = string.Format("OpenWindow({0},2);", cbYear.SelectedValue);

Try to place quotes around your dynamic value:

<td onclick="OpenWindow('<%= cbYear.SelectedValue%>', 2);return false;">
        &nbsp;
</td>

Otherwise, js might try to interpret the value as a variable.

Try the following:

<td onclick='<%= "OpenWindow(" + cbYear.SelectedValue + ", 2);return false;" %>'>
        &nbsp;
</td>

Or this:

<td id="td1" runat="server">
   &nbsp;
</td>

And from code do:

td1.Attributes.Add("onClick", "OpenWindow(" + cbYear.SelectedValue + ", 2);return false;");
