Find a control of an edit form in item command event

Hi,

I have a grid with an edit form with textboxes that I need to disable based on a button that is clicked in the form. I'm wondering if there is a way to find the textboxes in the itemcommand events that get triggered by the buttons?

I've been trying to use something like:

Private Sub RadGrid2_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid2.ItemCommand

If e.CommandName = "TimeInOutTextboxes" Then

Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)

Dim txtTimeIn As TextBox = DirectCast(editedItem.FindControl("txtTimeIn"), TextBox)

txtTimeIn.Enabled =

False

End If

but an error is thrown at "txtTimeIn.Enabled = False" because the control is not being found

Thanks

Pager details not working on production

Hello All,

I came across this strange issue happening only on production.

In my RadGrid, i have set the pager style as below, and its counting and displaying the paging details properly on local, dev and test environemnts (for example, 1,000 items in 10 pages)

<PagerStyle Mode="NextPrevAndNumeric" PageSizeLabelText="Page Size:" PageSizes="10,20,50" Position="TopAndBottom" PagerTextFormat="{4} {5:0,0} items in {1:0,0} pages" />

But on production, the counting of items and pages is behaving strange. For example, when i filter and sort or page to first or last page, the counting changes randomly and displays different numbers.

Can someone help me what must the issue?

I am binding the RadGrid with "asp:ObjectDataSource" (not using NeedDataSource event). I need to do this way, as this is an old code and cannot restructure everything for good reasons.

Please suggest.

Issues with page rendering with UI for ASP.NET AJAX R3 2016 update

We have an application that relies heavily on Telerik controls and noticed with the most recent update (ASP.NET AJAX R3 2016) we have some rendering issues in Chrome. (See attached pictures). Firefox, IE, etc. are all fine. You can see that there is a significant amount of padding between the two checkboxes.

This is only happening on our development environment and not our live environment. Is there something with this new update that would cause rendering issues in Chrome?

SetImageProperties_Constrain not working

When changing the properties of an image, an icon of a broken paperclip shows next to the height and width, which (if clicked) forces the proportions to be constrained.

Inside RadEditorProvider/App_LocalResources/RadEditor.Dialogs.resx, there is a Name of "SetImageProperties_Constrain" with a value of "Constrain". However, the properties window is always not-constrained by default... and must be clicked each time.

Our website is hosted on DNN7, which by default contains the Telerik RadEditor.

Any ideas on how to set it to be constrained by default?

Thanks,

-Adam

How can I check and validate dimensions of a picture before upload?

In my web application I use a AsyncUpload to load the picture of each user to their personal page.
I need to limit the dimensions (height and width) of uploaded images.

How can I validate the height and width of the images before they are loaded? Or convert them to the dimensions I want?
I need images have the dimensions 150x100
I have the following code to validate file type and file size of uploaded images.

foreach (UploadedFile file in LogoUpload.UploadedFiles)

{

//string filetype = LogoUpload.PostedFile.ContentType;

string filetype = file.ContentType;

long filesize = file.ContentLength;

byte [] input = new byte[filesize - 1];

long maxFileSize = 1024;

if (filesize > maxFileSize)

{

base.OnUIValidation("The file is too big.");

return;

}

string[] acceptedFileTypes = new string[3];

acceptedFileTypes[0] = "image/jpg";

acceptedFileTypes[1] = "image/jpeg";

acceptedFileTypes[2] = "image/jpeg";

bool acceptFile = false;

//should we accept the file?

for (int i = 0; i <= 2; i++)

{

if (filetype == acceptedFileTypes[i])

{

//accept the file, yay!

acceptFile = true;

}

Error Uncaught TypeError: Cannot read property 'ajaxRequest' of null

Hi, I have an ascx file that contains a RadNotification and a timer.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function OnClientUpdated(sender, args) {

sender.show()

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("content");

}

function UpdateWithoutPopup() {

var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");

ajaxManager.ajaxRequest(arguments);

}

</script>

</telerik:RadCodeBlock>

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Timer1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadNotification1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<asp:Timer ID="Timer1" runat="server" Interval="6000" OnTick="Timer1_Tick" />

<telerik:RadNotification RenderMode="Lightweight" id="RadNotification1" runat="server" loadcontenton="EveryShow"

width="300" height="150" animation="Fade" enableroundedcorners="true" enableshadow="true"

title="Received messages" offsetx="-20" offsety="-20" onclientupdated="OnClientUpdated"

titleicon="none" autoclosedelay="5000" Skin="Bootstrap">

<ContentTemplate>

<asp:Image ID="Image1" runat="server" CssClass="Max75" />

<asp:Literal ID="lbl" runat="server"></asp:Literal>

</ContentTemplate>

</telerik:RadNotification>

the timer makes the checks and if necessary displays a popup, another calls a function

public void Timer1_Tick(object sender, EventArgs e)

{

if (Check())

{

RadNotification1.Show();

}

else

{

string script = "UpdateWithoutPopup()";

ScriptManager.RegisterStartupScript(Page, typeof(Page), "myscript", script, true);

}

When I show the popup everything works fine when if I call the error function I get the error:

default.aspx:502 Uncaught TypeError: Cannot read property 'ajaxRequest' of null

how do I fix?

thanks in advance

RadTextBox - Password Mode

How do you get the EmptyMessage to show up when using password mode. It looks really funny when the username has the text in there but the password box is empty.
