Nested Datepicker in Panel Bars

When I use the javascript below on a regular page without panel bars, the code below works just fine.

var picker = $find("<%= datDueDate.ClientID %>");

picker.set_enabled(false);

However, when I use this code on a datepicker nested in radpanelbars, it does not work. How can I enable/disable a datepicker that is nested in radpanelbars?

Thank you in advance.

Is there a way to get a RadGrid to postback updates when a combo box inside the grid is changed -- preferably without leaving edit mode in the process?

Dynamic Control creating in ItemDataBound

I have a scenario where depending on the the values in a field of itemdata, I need to generate a different control. Obviously in ItemCreated the dataitem is not bound yet, but strangely if I add controls in ItemDataBound, they disappear by the time the control is rendered. For example:

If TypeOf (e.Item) Is RadListViewDataItem Then

Dim FormItem As MyFormItem = CType(CType(e.Item, RadListViewDataItem).DataItem, MyFormItem)

Select Case FormItem.TypeId

Case "Header"

Dim lbl As New Label

lbl.Text = String.Format("<b>{0}</b>", FormItem.Text)

e.Item.Controls.Add(lbl)

there the ItemTemplate is initially empty.

Is this possible?

Thanks,
Reuven

RadUpload not working while uploading 50MB file

WEB.CONFIG

<httpRuntime maxRequestLength="2024000" executionTimeout="10000"/>

ASPX

<telerik:RadUpload runat="server" ID="RadUpload1" Skin="WebBlue" ControlObjectsVisibility="None" MaxFileInputsCount="1" ReadOnlyFileInputs="true"></telerik:RadUpload>

When I try uploading locally I could upload 50MB file. But when I tried from server upload stops in middle with an error

404 - File or directory not found.

The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

can anyone reply me on how to handle upload for large files.

Thanks,

[Solved] Selecting a Tab from the RadTabStrip

I want to be able to set client side focus to the first field in a tab once the tab is clicked. I've tried the OnSelectedTab & OnSelectingTab client side events to run a js function, but when I click on one of the tabs, it doesn't get highlighted; nor does it go into my js function. If I take away the js event on the tabstrip, it works fine, but I can't set the focus to the first field. the last two tabs are optional and are disabled by default. They get enabled elsewhere in the code.

Here is my html:
<telerik:RadTabStrip ID="tsPatientDemographics" runat="server" AutoPostBack="false" OnSelectedTab="SetFocus"
ScrollButtonsPosition="Right" MultiPageID="RadMultiPage1"
BackColor="Gray" CausesValidation="False" Align="Left">

Here is my js:

function SetFocus() {

                var tabStrip = $find("<%= tsPatientDemographics.ClientID %>");
                var selectedTab = tabStrip.get_selectedTab();
                var HospAcctno = document.getElementById("HospAcctno");
                var GuarRelToPat = document.getElementById("GuarRelToPat");
                var priInsCode = document.getElementById("priInsCode");
                var secInsCode = document.getElementById("secInsCode");
                var terInsCode = document.getElementById("terInsCode");

if (selectedTab != null) {
var selectedTabValue = selectedTab.get_text();

                    if (selectedTabValue == "Patient") {
                        var HospAcctno = document.getElementById("HospAcctno");
                        HospAcctno.focus();
                    }
                    else if (selectedTabValue == "Guarantor") {
                        var GuarRelToPat = document.getElementById("GuarRelToPat");
                        GuarRelToPat.focus();
                    }
                    else if (selectedTabValue == "Pri Ins") {
                        var priInsCode = document.getElementById("priInsCode");
                        priInsCode.focus();
                    }
                    else if (selectedTabValue == "Sec Ins") {
                        var tabStrip = $find("<%= tsPatientDemographics.ClientID %>");
                        var tab = tabStrip.findTabByText("Sec Ins");
                        if (tab.get_isEnabled == true) {
                            var secInsCode = document.getElementById("secInsCode");
                            secInsCode.focus();
                        }
                    }
                    else if (selectedTabValue == "Ter Ins") {
                        var tabStrip = $find("<%= tsPatientDemographics.ClientID %>");
                        var tab = tabStrip.findTabByText("Ter Ins");
                        if (tab.get_isEnabled == true) {
                            var terInsCode = document.getElementById("terInsCode");
                            terInsCode.focus();
                        }
                    }

Valid and access controls in NestedView

Hello
I have a radgrid, there I have a nestedview with two-TAB controls and within
each tab a repeater control with a checkbox that tells me whether or not
selected an option from my database.
Since the option ItemCommand make it along the repeater and enable or disable the
options with the checkbox, my problem is how do I get each time
checkbox event access Oncheckedchangued return me the id code
grid and the repeater control to scroll it and store control
changes in my database.

I have an option that is to place a button and using the property commandname
ItemCommand capturing the event and do my validations and
routes, not if you have a more direct option to control
checkbox inside the repeater and nestedview.

Thanks

Alex Alfonso

Grid Export Buttons and AJAX

I have read that i need to exclude the export to excel and pdf buttons of the RadGrid from the AJAXified requests. I found the following article outlining this:

http://www.telerik.com/help/aspnet-ajax/ajxexclude.html

However i have two questions as this does not help me much:

1) When i add the OnRequestStart property to my ClientSettings like this:

<ClientSettings AllowDragToGroup="True">

<Scrolling AllowScroll="True" ScrollHeight="600px" UseStaticHeaders="True" />

<ClientEvents OnRequestStart="gridRequestStart" />

</ClientSettings>

I get the following error: Type 'Telerik.Web.UI.GridClientEvents' does not have a public property named 'OnRequestStart'.

2) These buttons are generated by the Radgrid and i am unable to access them like the example shows...

Could someone help me to get this functionality working again? Thanks,

Grid
