Telerik Controls not loading correctly

I am having serious issues with Telerik controls not loading on the page without multiple refreshes.

Here is an example of how the HTML editor looks when it fails to load. This happens to pretty much all controls.

Using version: Telerik_UI_for_ASP.NET_AJAX_2015_3_930_Dev

No errors are being thrown on the server.

Reordering columns client side & Saving order in DB

Hello,

I was looking for a way to allow my users to customize their interface, and to choose the columns order of some grids.
I choose a client side reordering as I don't want the data to be reloaded (too long) and the ongoing modification lost (GridEditMode.Batch).

In order to save the preference of the user, I susbcribed to the "onColumnSwapped" event. Then my javascript function calls "ajaxManager.ajaxRequest" (which save the new columns order into my database)

First issue: in my "RadAjaxManager1_AjaxRequest" (server side), if I look the OrderIndex of the columns of my grid, they have their original values. Is this normal ?

I could decide to save the profil with a custom button "Save Column Order" (I tried and the OrderIndex are the correct / changed ones) but I want to avoid adding another button to my interface.

As I already have the column order stored server side, I decided to simply send the two argument from the javascript to my server function:

var sourceIndex = eventArgs.get_gridSourceColumn().get_element().cellIndex;

var destinationIndex = eventArgs.get_gridTargetColumn().get_element().cellIndex;

Then I make the change myself server side and save it to the database.

It works well with GridClientSettings.GridColumnsReorderMethod.Swap.

However it doesn't work with GridClientSettings.GridColumnsReorderMethod.Reorder. The javascript event is called multiple times (swapping multiple time) but the ajax request is called only 1 time ! (the last time).

Example: If I move the 4th columns to position 1.
The javascript event is called 3 times with the following parameters (source, destination):
4,3
3,2
2,1

And my AjaxRequest is called only 1 time with the following parameters (source, destination):
2,1

Any suggestions ?

Thank you

Image not displayed

Hi,

The image does not appear in Chrome on Android (Version 55.0.2883.91). On Windows, the image is displayed correctly.

The version of Telerik.Web.UI is 2017.1.228.40.

My code is:

<telerik:RadDatePicker ID="rdpLieferTermin" runat="server" Culture="de-CH" Skin="Bootstrap">

<Calendar runat="server" UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x"

Skin="Bootstrap"></Calendar>

<DateInput runat="server" DisplayDateFormat="dd.MM.yyyy" DateFormat="dd.MM.yyyy" onchange="validateText(this)"

onkeyup="validateText(this)"></DateInput>

</telerik:RadDatePicker>

See attached files (on windows: File1.png, on Android: File2.png)

Thank you for your help!

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;

}

<telerik:RadGrid ID="rgrdTrips" runat="server" AutoGenerateColumns="true" AllowPaging="false"

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
