[Solved] Javascript in Telerik controls

[Ayesha]

Hi All,

When the RAdToolBar Button is clicked , i need to invoke the javascript function. I tried to do in the below method but javascript function is not getting called!! pls help
this is ascx(since I'm using an user ctrl)

<

 

script type="text/javascript">

 

 

function DateValid()

 

{

alert(

"End Date cannot be lesser than the Start Date");

 

}

and in ascx.cs, I have the below lines to call the js function.

 

 

if (obDoSchedule.DtStartDate >= obDoSchedule.DtEndDate)

 

{

ctlButtonBar.Attributes.Add(

"onClick", "return DateValid();");

 

}

Is this correct? I'm not getting the javascript alert msg even if DtStartDate >=DtEndDate.Pls help!!

Hi Zaheka,

I tried your code and it is working fine in my end. I am getting the alert when clicking the ToolBarButton after adding the OnClick attribute to RadToolBar. If you want to show alert right from server code instead of adding onclick Attribute from server, then you can try the following code.

C#:

ScriptManager.RegisterStartupScript(this, this.GetType(), "MyScript", "DateValid();", true); // shows alert

Another option is attaching OnClientButtonClicked event for RadToolBar and check for condition (if possible) in client side to show alert.

Thanks,
Princy.

Hello Princy,

 

I have a similar problem to Zeheka's but on the ItemCommand event.

I've tried 

 

Response.Write(

"<script ... >alert('something')</script>"),

 

ScriptManager

 

.RegisterStartupScript(page, page.GetType(), "myKey", "<script ... >alert('something')</script>", false),
page.RegisterStartupScript("myKey", jScript),
and

 

page.ClientScript.RegisterStartupScript(page.GetType(),

"myKey", "<script ... >alert('something')</script>").

but all didn't work!, so could you please tell me how to solve this issue ?

my original code:

 

public static void alert(System.Web.UI.Page page, string msg)

 

{

 

    string jScript= "<script>alert ('something')</script>";

 

 

    ScriptManager.RegisterStartupScript(page, page.GetType(), "keyClientBlock", jScript, false);

 

    //page.ClientScript.RegisterStartupScript(page.GetType(),

"myKey", jScript);

 

    //page.RegisterStartupScript(

"keyClientBlock", jScript);

 

}

 

 

and note that the page is a content aspx page

Regards.
