We are attempting to update the drag handle text to match the current value. The basic technique is outlined here: https://www.telerik.com/forums/display-the-current-values

The problem is that the text is not updated when the page is loaded. We tried to access the drag handles (get_dragHandles()[0]) in the client load event, but the drag handles are null at that point. Looking at the state of the control at this point shows some interesting values such as "initialized internal" being false and not value being set the for the "drag handle element". If I retrieve the drag handles in another event such as value changed they exist and these values are set as expected.

_dragHandleElement: null
_initializedInternal: false

We simplified our example down to the following and the behavior is reproducible. We are using version 2019.1.215.45 of the controls.

<telerik:RadSlider ID="sldTest" RenderMode="Lightweight" BackColor="Red" Value="50" ForeColor="Blue" MinimumValue="0" MaximumValue="100" Width="500" ShowDragHandle="True" OnClientLoad="sldTest_ClientLoad" OnClientValueChanged="sldTest_ClientValueChanged" runat="server" />

function sldTest_ClientLoad(slider, args) { //alert(slider.get_dragHandles()[0]); } function sldTest_ClientValueChanged(slider, args) { alert(slider.get_dragHandles()[0].firstChild.innerHTML); }

[Solved] RadGrid Batch Update with AjaxRadManager

Hi,

I am trying to implement Batch edit mode for radGrid where on cell value changed triggers a javascript function. This function saves the changes made to the grid. I have this part working.

I wanted to do the same call using ajax but I couldn't find a way to do it. Following are the required details of this problem.

1. RadGrid is being added from codebehind and is added in a radPane like this.radpane.Controls.Add(RadGrid).

2. RadAjaxManager exists on the MasterPage and I am able to call the instance of it on my page.

Can someone guide me how to get this to work?

Thanks,

Swanand Nalawade

[Solved] How to set Maximum Dropdown Height

There is a DropDownHeight property that sets the height of the dropdownlist. How do I make this work like the MaxHeight property of the RadCombobox? It looks ridiculous with 1 entry with a large size set (eg 300px). If I allow the autocompletebox to resize the dropdownlist by itself, then its fine with a few records, but it scrolls off the page when many records match the filter.

AsyncUpload Progress freezing at 2mb

Hello,

We've been using the Telerik Upload and AsyncUpload since 2013 and they usually work great.

However in the last 24 hours an issue has started to pop up where some of our customers are unable to upload. The upload starts and freezes at 2 mb in the Progress Control.

I'm wondering if anyone else is having the same issue.

slider drag handle responds slow

I have a slider with divs that get updated on clientside with the slider value.

I noticed that my slidervalue changes first and there's a little lag when the draghandle responds. Below is my slider definition and my client side code. Could you help me figure the delay in the drag handle response?

<telerik:RadSlider ID="RadSliderAge" runat="server" MinimumValue="0" MaximumValue="90"

IsSelectionRangeEnabled="true" SelectionStart="45" SelectionEnd="70" SmallChange="1"

OnClientSlide="clientValueAgeChange" OnClientLoad=

"clientValueAgeLoad" ShowDecreaseHandle="true"      ShowIncreaseHandle="true"  TrackMouseWheel="false"

    ThumbsInteractionMode="Lock" Skin="Material"

>

</telerik:RadSlider>

function clientValueAgeLoad(sender, eventArgs) {

var CurrentAgeCtrl = document.getElementById("CurrentAgeCtrl");

var RetirementAgeCtrl = document.getElementById("RetirementAgeCtrl");

CurrentAgeCtrl.innerHTML = sender.get_selectionStart();

RetirementAgeCtrl.innerHTML = sender.get_selectionEnd();

}

function clientValueAgeChange(sender, eventArgs) { var CurrentAgeCtrl = document.getElementById("CurrentAgeCtrl"); var RetirementAgeCtrl = document.getElementById("RetirementAgeCtrl"); CurrentAgeCtrl.innerHTML = sender.get_selectionStart(); RetirementAgeCtrl.innerHTML = sender.get_selectionEnd(); CalcOutputs(); }

[Solved] Won't AutoCompleteBox fire JS events?

I would like to implement a feature that depends on what user types in -- so I need to constantly check the contents of the input box. The obvious way of doing it is by running a JS function invoked by the onkeyup (or onkeypress, etc) but AutoCompleteBox is not firing the event.

A snippet of my code:

<script>

function ChangeTest() {

console.log('changed');

}

</script>

<telerik:RadAutoCompleteBox RenderMode="Lightweight" runat="server" ID="RadAutoCompleteBox1"

autopostback="true"
