Hi Guys,

One of our developers has been using the telerik controls such as the scheduler, tab strip, etc. for several months now.  Most of our customers use IE7/IE8.  And, we see a definite performance decrease when using any telerik controls with those browsers.  In FireFox, the performance appears better.

It has gotten to the point where my developer is going to pull the telerik controls from our product and go to other 3rd-party tools because the customers are complaining about the sluggish performance.  Granted, some customers have weak client computers while others have top-of-the-line.  In almost all cases, the telerik controls perform terrible in IE.

I know Microsoft's browsers may have issues that FireFox does not, but IE is not going anywhere, and something must be done to support it better.

My developer has looked at the top 10 list for increasing telerik performance, and we have tried everything to trim down the code supporting the telerik controls to make them function lean, mean, and fast.  But, this still has not given us the performance that we expect.

Even when using the live demos at telerik of the scheduler, the demos work better on FireFox, etc. than in IE.  Something must be done to correct this.  Again, IE is not going anywhere.

If you have any betas, coding suggestions, etc., I would gladly welcome them.  Until a fix is available for performance, I cannot afford to keep using telerik in the future.

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

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.

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?

Hi,

I am using the RadPivotGrid to navigate a OLAP cube on Microsoft Analysis Service. The control connects to the cube through Adomd connection string.
I would like to retrieve the MDX query releated to my navigation. Is it possible?

Thanks in advance.

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

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;
            }
             }
