I want to pass some argument to javascript function from code behind. My Javascript function as follow. how to send arg to this func. from server side code.
function addTab(tabid,tablist) {
//to Find the Panel
var Panel = $find("<%=RadPanelBar2.ClientID %>");
//To find the Tab Strip
var tabStrip = Panel._findItemByValue("QueueGridPanel").findControl("RadTabStrip2")
tabStrip.get_tabs().clear();
var newTabNames = "MyTab1,MyTab2,MyTab3";
//var newTabNames = document.getElementById("ctl00_GridContentPlaceHolder_hfTabs").value;
var TabsNames = newTabNames.split(',');
var i = 0;
while (i < TabsNames.length) {
var ntab = new Telerik.Web.UI.RadTab();
tabStrip.get_tabs().add(ntab);
ntab.set_text(TabsNames[i]);
i++;
}
return false;
}
Check out RegisterClientScriptBlock at MSDN. You can use it to insert Javascript after a postback.
String csName = "myScript";
Type csType = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the client script is already registered.
if (!cs.IsClientScriptBlockRegistered(csType, csName))
{
StringBuilder csText = new StringBuilder();
csText.Append("<script type=\"text/javascript\"> ");
csText.Append("addTab(" + myTabID + ", " + myTabList + "); </");
csText.Append("script>");
cs.RegisterClientScriptBlock(csType, csName, csText.ToString());
}
The RegisterClientScriptBlock method inserts the client-side script immediately below the opening tag of the Page object's element.
For the uses which you're describing here, I use an asp:Literal control and pump in global javascript declarations.
<script type="text/javascript">
var FirstNameId = "<%=Me.txtFirstName.ClientID%>";
var MiddleNameId = "<%=Me.txtMiddleName.ClientID%>";
var LastNameId = "<%=Me.txtLastName.ClientID%>";
</script>
Then when I need them later on, they are available to the entire page.
