Uncaught ReferenceError: True is not defined

I run my ASP.NET WebForm with C# Project, its appear some error message as below:

I try to add signalr mechanism. PassPDFRequest is the javascript function to send data to signalr server. But I also have another problem I cannot add valiad breakpoint in the aspx for debugging the javascript code. So I cannot see the parameters of the PassPDFRequest function in aspx.

I run the PassPDFRequest with RadScriptManager. I also used the ScriptManager. But the error message are the same.

Does somebody know how to solve this problem？

string szJs = "PassPDFRequest('" + ViewState["HospArea"].ToString() + "','" + pdfPath + "','" + szPathHttp + "','" + szPathPhy + "'," + pageIndex.ToString() + "," + isOpen.ToString() + ");";

RadScriptManager.RegisterStartupScript(this, this.GetType(), "KeyPassPDFRequest", szJs, true);

RadGrid CheckBox in the header

I have a RadGrid with 3 checkbox columns with a checkbox in the header of those 3 columns. I'm trying to check/uncheck only the checkboxes belonging to the column whose header checkbox is checked.

With the code that I have even though I'm checking/unchecking checkbox of only one header, it is checking/unchecking all the checkboxes in all the 3 columns

How do I change my code to check/uncheck only the checkboxes belonging to the header checkbox that has been checked/unchecked?

Appreciate your help!

var gridToCheckAll = '<%= rgrdTrips.ClientID %>';

function checkAllRows(sender) {

var checked = sender.checked;

var container = document.getElementById(gridToCheckAll);

var checkboxes = container.getElementsByTagName('input');

for (var i = 0, l = checkboxes.length; i < l; i++) {

if (checkboxes[i] != sender && !checkboxes[i].disabled)

checkboxes[i].checked = checked;

}

Find Header Checkbox

Hi all!

In my Radgrid I inserted a <HeaderTemplate> with a checkbox where it checks/unchecks all the checkbox items. Now if I check/uncheck on of these checkbox items, I want to check/uncheck the header checkbox, but I can't find how.

I'm doing this client side via javascript. Can't do it server side.

function CheckReview(chk) {

var grid = $find("<%=RadGrid.ClientID %>");

var masterTable = grid.get_masterTableView();

var flag = true;

//this line doesn't find the header control

var gridHeaderElement = masterTable.get_dataItems()[0].findElement("chkH");

for (var i = 0; i < masterTable.get_dataItems().length; i++) {

if (!chk.checked) {

flag = false;

}

if (flag) {

gridHeaderElement.checked = true;

}

else {

gridHeaderElement.checked = false;

}

How to Save Expanded State of a RadTree

Hi, We are using Telerik 2017.1.228.45 RadTree controls. We have implemented RadTree contract inside a usercontrol and it's getting called through a master page. all Radtree nodes has a customUrl field populated,so when they are clicked on the same page, a user control appears and when some changes are made to that user control and is closed, RadTree loses its expanded state.

Is there a way to persist RadTree in that expanded state please? if yes, then how?

Thank you

turn multiple rows into columns

Would it be possible to take the following recordset example and divide into multiple columns and then rows? Currently we use a repeater to accomplish the goal but like the styling of the grid. The RadGrid would give us more control of styling and exporting of the data much easier.

state TotalCUs TotalExcess TotalQualified

AL 4 3 0

CA 18 10 1

CO 1 1 0

DC 2 2 0

FL 6 6 0

GA 1 1 0

What we would like is to have 3 columns and then however many rows to complete the recordset.

state TotalCUs TotalExcess TotalQualified

AL 4 3 0 CA 18 10 1 CO 1 1 0

DC 2 2 0 FL 6 6 0 GA 1 1 0

ID 8 3 0 IL 26 9 0 IN 18 4 0

KS 1 1 0 KY 2 2 0 MD 2 0 0

ME 4 4 0 MI 4 3 0 MN 5 4 1

MO 5 5 0 NH 2 2 0 NJ 3 3 0

NV 7 4 0 OH 61 19 0 OK 2 2 0

OR 1 1 0 PA 6 6 0 TX 9 5 0

WA 2 2 0

Thanks for your help in advance.

Disable/Hide 'Save on server' option

I want to implement this on our admin sites & been looking at the demos, particularly the default save options. The issue is we save images in various locations. I am presuming that the 'Save on Server' option uses the path in ImageUrl, so saving it just in one place will not be applicable in this case. So I was thinking of hiding or disabling that option, and hide the overwrite check box, to only have 'Download Image' as the only option?

Now, what I might end up doing is implementing the custom save option and have a dropdown of all the various image paths on the site to save to when the user is saving. However, can you look into my query above and see if that is an option?

Also, is there a way to add a custom aspect ratio to the dropdown in the crop function?

Attach ClientEvents-OnDateSelected from JavaScript

I use a combination of different controls in an ASP.Net Repeater. Included are now already 2 RadComboBoxes. I add the SelectedIndexChanged to them in this way:

for (var i = 0; i < aClientIds.length; i++) {<br> var comboBox = $find(aClientIds[i]);<br> var id = comboBox.get_id();<br> comboBox.add_selectedIndexChanged(ddlList_SelectedIndexChanged);<br>}

The list of ClientIds are saved to a hidden field from Codebehind and retrieved to a JavaScript array in the js.file associated with the usercontrol where the Repeater is shown. Works nicely. I also must include a RadDatePicker and attach ClientEvents-OnDateSelected in the same way. Already have this working and get the correct id:

for (var i = 0; i < aDateClientIds.length; i++) {<br> var calendar = $find(aDateClientIds[i]);<br> var id = calendar.get_id();<br> alert('id:' + id);<br>}

But how do I attach ClientEvents-OnDateSelected from JavaScript? I can't find this in the Telerik documentation or on Google.

My Company uses Telerik.Web.UI version 2015.3.1111.45

Agenda view displaying next week not current week

Hey,

So I'm using the RadScheduler and I have Agenda View enabled, but I've noticed that anytime I click on it, the scheduler displays the agenda for the next week, not the current week. Any ideas why this could be?

<telerik:RadScheduler ID="RadScheduler1" runat="server" DataKeyField="ID" AllowInsert="False" DataSubjectField="Subject"
DataStartField="StartDate" DataEndField="EndDate" FirstDayOfWeek="Monday" LastDayOfWeek="Friday" ReadOnly="True" SelectedView="WeekView" Height="650px" WorkDayEndTime="18:00:00">

<ExportSettings>
<Pdf PageTopMargin="1in" PageBottomMargin="1in" PageLeftMargin="1in" PageRightMargin="1in"></Pdf>
</ExportSettings>
<TimelineView UserSelectable="False" />
<AgendaView ReadOnly="True" UserSelectable="True" ResourceMarkerType="Bar" NumberOfDays="5" />
