Fail to find combo

Hi,

I have this piece of code:

<script type="text/javascript">

function setEmpty()

{

var combo = $find("<%= combo1.ClientID %>");

combo.clearselection();

combo.set_emptyMessage("select please");

}

function nodeClicking(sender, args) {

var comboBox = $find("<%= combo1.ClientID %>");

var node = args.get_node()

comboBox.set_text(node.get_text());

comboBox.trackChanges();

comboBox.get_items().getItem(0).set_text(node.get_text());

comboBox.get_items().getItem(0).set_value(node.get_value());

comboBox.commitChanges();

comboBox.hideDropDown();

// Call comboBox.attachDropDown if:

// 1) The RadComboBox is inside an AJAX panel.

// 2) The RadTreeView has a server-side event handler for the NodeClick event, i.e. it initiates a postback when clicking on a Node.

// Otherwise the AJAX postback becomes a normal postback regardless of the outer AJAX panel.

//comboBox.attachDropDown();

}

function StopPropagation(e) {

if (!e) {

e = window.event;

}

e.cancelBubble = true;

}

function OnClientDropDownOpenedHandler(sender, eventArgs) {

var tree = sender.get_items().getItem(0).findControl("rvt1");

var selectedNode = tree.get_selectedNode();

if (selectedNode) {

selectedNode.scrollIntoView();

}

</script>

<telerik:RadComboBox ID="combo1" runat="server" CausesValidation="false"

EnableEmbeddedSkins="false" OnClientDropDownOpened="OnClientDropDownOpenedHandler"

EmptyMessage="select please" MaxHeight="200px" ShowToggleImage="True"

Width="50%" AllowCustomText="True">

<ItemTemplate>

<div id="div1">

<telerik:RadTreeView ID="rvt1" runat="server" Width="100%" Height="250px"

DataSourceID="ds1" DataFieldID="ID" DataValueField="ID"

DataFieldParentID="ParentID" DataTextField="Name" OnClientNodeClicking="nodeClicking" >

<DataBindings>

<telerik:RadTreeNodeBinding Expanded="true" />

</DataBindings>

</telerik:RadTreeView>

</div>

</ItemTemplate>

<Items>

<telerik:RadComboBoxItem Text="" />

</Items>

</telerik:RadComboBox>

<asp:ObjectDataSource ID="ds2" runat="server"

EnablePaging="True" OnSelecting="dds2_Selecting"

SelectMethod="GetList" TypeName="BLL">

<SelectParameters>

<asp:Parameter Name="p1" Type="Int32" />

<asp:Parameter Name="p2" Type="Int32" />

<asp:Parameter Name="p3" Type="Boolean" DefaultValue="True" />

</SelectParameters>

</asp:ObjectDataSource>

The combobox is inside a panel. When I show the panel, I call the function setEmpty() to clear the previous data. The problem is that I get a javascript exception. Debugging, I realize that the that the find("<%combo1.ClientID %>"); is returning null... ie it is not able to find the combo1.ClientID. The strange thing is that the function nodeClicking is working, ie, when I click in a node, the nodeClicking function is properly executed... The only problem is with tje setEmpty() function.

Issue with RadAjaxLoadingPanel

Hello,

In our application, we have a scenario where we need to handle multiple ajax postbacks executing in parallel. We have set "RequestQueueSize" of the Ajax Manager to 10 to accomplish this,

After doing so, We found a problem when we tested the scenario outlined below :

We have 2 combos(Say combo1 and combo2) on a page, both of which cause postbacks to populate different fields . We executed the following steps:

1. choose a value in combo1. Combo 1 posts back to fetch and populate related values on our page
2. change the selected value in combo1. While its postback is executing, choose a value in combo2.

On doing this we found both postbacks execute successfully. But After combo2's postback finishes executing, the state of combo1 is restored to what it was after step1 above.

Any help with solving this problem would be greatly appreciated.
Thank you

passing variables into the radConfirm callBack function

Hi,

My problem is very simple. When I deleted a user from my grid, I want to call radConfirm (from RadAjaxManager) from the serverside and send some info to the callback js function, but I don't know how to pass variables into the radConfirm. I found this trick, but it only work if my radConfirm call come from a Js function, Like I said, my call come from the serverside. So, I tried to call a Js function from the serverside with the following code :

string script = "<script language='javascript'> " +
" jsFunction(" + myVar + ");" +
"</script>";

Page.ClientScript.RegisterStartupScript(this.GetType(), "script ", script );

This seem to work, except that if I make a Telerik instruction in the jsFunction (like radconfirm), it doesn't work (Chrome's java
console said that I can't call radConfirm from undefined).

So, may someone help me? How may I do it ?
Thank you

David

AjaxUpdate panel and ClientScriptManager.RegisterClientScriptInclude error

I have a form inside a RadAjaxUpdatePanel, the form uses a custom buttom to preview data from the form. It does this using a javascript onclick event that is defined in a .js class in the custom project ( seperate from the form). the .js file is registered like so:

    
                        ClientScriptManager cs = this.Page.ClientScript;  
        
                        Type rsType = this.GetType();  
        
                        cs.RegisterClientScriptInclude("JobScript", cs.GetWebResourceUrl(rsType, "CareerCenter_Classes.JsScripts.Jobs.js"));

The page shows that the script is registered (using IsClientScriptIncludeRegistered), However when I try to use the button, I get a javascript error "object expected".

I know the javascript code works, It only broke when I tried to ajax the page. does anyone know what I can do to fix this?

RadAjaxManager - Client Event OnResponseRecieved not appearing

Hi there

I am having issues with using the RadAjaxManager and the client events. I can only use the following 2:

OnRequestStart and OnResponseEnd

<telerik:RadAjaxManager ID="RadAjaxManager" runat ="server">
<ClientEvents OnRequestStart="startRequest" OnResponseEnd="endResponse">
</telerik:RadAjaxManager>

I need to use the following ClientEvents but they don't appear:

OnRequestSent and OnResponseReceived

Issue that is occuring is that upon an error occuring within the build and an exception being thrown doesn't invoke the OnResponseEnd="endResponse" and thus my function endResponse doesn't run

function endResponse(sender, eventArgs)
{
parent.enableTabs();
}

So I would like to use the onResponseRecieved so that even if an exception is thrown onResponseRecieved will still run a function

<telerik:RadAjaxManager ID="RadAjaxManager" runat="server">
<ClientEvents OnRequestStart="startRequest" OnResponseEnd="endResponse" OnResponseReceived="receiveResponse"/>
</telerik:RadAjaxManager >

function receiveResponse(sender, eventArgs)
{
parent.enableTabs();
}

I was wondering if it could be down to the Telerik.Web.UI.dll we are using as version is 2009.02.0826.20

Any responses or help are greatly appreciated!
