Hi,

I have a run-time generated RadWindow that has a variety of controls in it. The RadWindow opens correctly when triggered, but when one of the buttons in the RadWindow is pressed, it causes postback, which wipes out the RadWindow.

How can I get client side Javascript to work without posting back to server?

Below is the EditText sub that is called when a button is pressed that should open the RadWindow with the RadEditor in it. When either the Save or Add button is pressed, the RadWindow disappears, and it doesn't look like it hits the Javascript functions.

Below that is the html for the page including some rudimentary javascript functions at the bottom I am trying to use to test this.

Thanks so much for looking at this!

aspx.vb

Private Sub EditText(ByVal sender As Object, ByVal e As System.EventArgs)

Dim buttonId As String

Dim x As Integer

Dim AN As Integer

If C.UserSelectedAssessmentType = "CREATE" Then

AN = C.UserSelectedAssessmentCount

Else

AN = C.UserSelectedAssessment

End If

buttonId = DirectCast(sender, RadButton).ID

x = Mid(buttonId & " ", 8, 2)

EditingStatement = x

w1.ContentContainer.Controls.Add(New LiteralControl("<div><table style=""width:725px""><tr><td>"))

editL1.Text = "Use this editor"

w1.ContentContainer.Controls.Add(editL1)

w1.ContentContainer.Controls.Add(New LiteralControl("</td><td style=""text-align:right"">"))

editSave.AutoPostBack = False

editSave.CausesValidation = False

editSave.OnClientClicked = "EditClickSave"

editSave.ID = "editSave"

editSave.Text = "Save"

editSave.Width = 128

w1.ContentContainer.Controls.Add(editSave)

w1.ContentContainer.Controls.Add(New LiteralControl("</td></tr></table>"))

Hi,

Please have a look into the sample code snippet to achieve your scenario.

ASPX:

<telerik:RadButton ID="RadButton1" runat="server" Text="OpenWindow" OnClick="RadButton1_Click">

</telerik:RadButton>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" VisibleOnPageLoad="true">

</telerik:RadWindowManager>

VB:

Protected Sub RadButton1_Click(sender As Object, e As EventArgs)

Dim Button1 As New Telerik.Web.UI.RadButton()

Button1.Text = "Demo"

Button1.AutoPostBack = False

Button1.OnClientClicked = "ClientClicked"

Dim window As New Telerik.Web.UI.RadWindow()

window.VisibleOnPageLoad = True

window.ContentContainer.Controls.Add(Button1)

RadWindowManager1.Windows.Add(window)

End Sub

JS:

<script type="text/javascript">

function ClientClicked(sender, args) {

alert("fired");

}

</script>

Let me know if you have any concern.
Thanks,
Princy,

Princy,

Thanks for looking at this for me.

I have isolated the issues I am having and have included the aspx and aspx.vb below so you could recreate this if you want to.

The first issue is when the RadWindow is drawing the RadEditor; none of the controls are visible; just the content section of the editor.

Secondly, in the RadWindow, whenever you click on either button, the expected result is not achieved. The javascript doesn't seem to be behaving as expected in relation to working with the RadEditor contents. The buttons just cause the RadWindow to close instead of performing their expected functions.

Any help you could provide would be GREATLY appreciated!
