Hello, I'm having the common "postback eats a buttonclick event" problem as discussed here and here.
I have a RadButton:

<rad:RadButton ID="btnApplyFilters" runat="server"

Text="Apply Filters" UseSubmitBehavior="false" />

Conflicting with a RadComboBox:




<rad:RadComboBox runat="server"
 ID="rcbSearchLastName"
 EnableLoadOnDemand="true"
 OnItemsRequested="rcbSearchLastName_ItemsRequested"
 AutoPostBack="true"
 ShowWhileLoading="false"
 ShowToggleImage="false" />

When I type in the textbox I am getting suggest style choices in the dropdown. If I select from the dropdown choices the rcbSearchLastName.SelectedIndexChanged event fires in the code behind. While I am typing the rcbSearchLastName_ItemsRequested event is fired.

If I type in the TextBox portion of the RadCombBox, then click a RadButton, the button click event is not fired.

Is it possible to use the components differently so that this conflict doesn't occur? Or is there a way to queue the events with the AjaxManager?

Thanks,
Dan

OnItemRequested not firing when Scriptmanager Navigate event is implemented

Dear Support Team,

I'm facing a problem with ComboBox control in a scenarion using LoadOnDemand.

When registering an Navigate Event in the ScriptManager on the page :

<asp:ScriptManagerProxy ID="proxyScriptManager" OnNavigate="proxyScriptManager_Navigated" runat="server">
</asp:ScriptManagerProxy>

The ComboBox's Event "OnItemRequested" is not firing (or maybe firing and handled in the proxyScriptManager_Navigated
event handler).

When removing the event handler :

<asp:ScriptManagerProxy ID="proxyScriptManager" runat="server">
</asp:ScriptManagerProxy>

The "OnItemRequested" returns to work just fine.

Any ideas how to solve this issue ?

Regards,

Itamar

How to submit a form using javascript when we use radAjaxPanel

Hi

I use this code for submit my form to our bank gateway:

<%@ Page Language="C#" %>

<!DOCTYPE html>

protected void submit(object sender, EventArgs e)

{

ClientScript.RegisterStartupScript(typeof(Page),

"ClientScript",

"<script language='javascript' type='text/javascript'> postRefId();</"+"script> ",

false);

}

</script>

function postRefId() {

var form = document.createElement("form");

form.setAttribute("method", "POST");

form.setAttribute("action", "http://bmi.ir");

form.setAttribute("target", "_self");

document.body.appendChild(form);

form.submit();

document.body.removeChild(form);

}

</script>

</head>

<body>

<div>

<asp:Button ID="Button1" runat="server"

Text="Button"

OnClick="submit" />

</div>

</form>

</body>

</html>

But when I use RadAjaxPanel like this, I can’t submit my form:

<%@ Page Language="C#" %>

<!DOCTYPE html>

protected void submit(object sender, EventArgs e)

{

ClientScript.RegisterStartupScript(typeof(Page),

"ClientScript",

"<script language='javascript' type='text/javascript'> postRefId();</"+"script> ",

false);

}

</script>

function postRefId() {

var form = document.createElement("form");

form.setAttribute("method", "POST");

form.setAttribute("action", "http://bmi.ir");

form.setAttribute("target", "_self");

document.body.appendChild(form);

form.submit();

document.body.removeChild(form);

}

</script>

</head>

<body>

<div>

<tlk:RadScriptManager ID="RadScriptManager1" runat="server" />

<tlk:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<asp:Button ID="Button1" runat="server"

Text="Button"

OnClick="submit" />

</tlk:RadAjaxPanel>

</div>

</form>

</body>

</html>

How can I fix it?

Changing context menu programmatically client-side?

Hello,
I'm using the prometheus editor to create mail merge files, and I've been trying to use img tags as placeholders for the merge fields. My question is, is it possible to make the context menu items for this mergefield img tag (it would have an attribute marking it as a mergefield) different from those of a regular img tag? Is it possible to access the object model for the context menu after the img is selected and before the menu pops so I can set the visibility of each menu item? Any help would be greatly appreciated.
Thanks,
David

Rad Combo Box refreshes the whole page

Hi there,

I have two Rad combo boxes, the value of the second one pops up when the first one is selected. The problem is the whole page refreshes if I use the OnSelectedIndexChanged property

OnSelectedIndexChanged

= "ddlName_SelectedIndexChanged"

protected void ddlName_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

//refresh the value of the second combo box here

}

Anyone knows how to only let the value of the second Combo box refresh, not the whole page? Any help is very much appreciated.

Custom List of Filter Functions for Custom Field Editor

I've created a custom dropdown field editor as outlined in this post and everything works great. I'd like to change the list of filter functions for the editor. For instance, in the case of the dropdown editor, I only need a few options: equal to, not equal to, is null, is not null. How can I customize this list?

Please see the attached image where I've highlighted the area in the expression I'm talking about.
