We're experiencing intermittent issues with RadAsyncUpload getting stuck on the yellow progress meter and never finishing the upload of a file. It's also causing IE to crash when this happens. 

I found this bug report that claims an issue with IE has been resolves, but we are still experiencing the issue.

We're currently using Telerik_UI_for_ASP.NET_AJAX_2015_1_225_Dev_hotfix​

Telerik version - 2016.1.225.45

I am trying to present a slideshow with images (and videos) bound from the DB (varbinary). This has worked in the past using RadRotator, however this control is not responsive (feel free to correct me if that is wrong). That said, I found a nice RadImageGallery demo (https://demos.telerik.com/) but I would like to load the items server-side (via OnItemDataBound). Here is my relevant code:

aspx
<telerik:RadCodeBlock runat="server">
        <script type="text/javascript">
            function onImageGalleryCreated(sender, args) {
                sender.get_imageArea().get_element().style.height = sender.get_element().clientHeight - parseInt(sender.get_thumbnailsArea().get_element().style.height, 10) + "px";
            }
        </script>
    </telerik:RadCodeBlock>
<telerik:RadImageGallery ID="PresentationView_RadImageGallery" Height="100%" runat="server"
OnItemDataBound="PresentationView_RadImageGallery_ItemDataBound" 
OnNeedDataSource="PresentationView_RadImageGallery_NeedDataSource">
<Items>
<telerik:ImageGalleryTemplateItem>
<ContentTemplate>
<telerik:RadBinaryImage ID="binaryFullContent" CssClass="itemTemplate" SavedImageName='<%#Eval("ID") %>' runat="server"/>
</ContentTemplate>
</telerik:ImageGalleryTemplateItem>
</Items>
<ClientSettings>
<ClientEvents OnImageGalleryCreated="onImageGalleryCreated" />
</ClientSettings>
</telerik:RadImageGallery>

aspx.cs
protected void PresentationView_RadImageGallery_NeedDataSource(object sender, ImageGalleryNeedDataSourceEventArgs e) {
PresentationView_RadImageGallery.DataSource = GetPresentationSlideList();
}
protected void PresentationView_RadImageGallery_ItemDataBound(object sender, ImageGalleryItemEventArgs e) {
if (e.Item is ImageGalleryItem) {
RadBinaryImage img = (RadBinaryImage)PresentationView_RadImageGallery.FindControl("binaryFullContent");
// img is null
}
}

I may be wrong in how to manually save data here, as I'm learning how to work with a Batch grid. If so, please correct me...

I have a RadGrid in Batch mode. When the user has made all changes to the header textboxes at the top of the form, and the detail values in the RadGrid below them, the user needs to click a general Save button to save all the data to the DB. (I'm hiding the "Save changes" button in the grid.)

When the Save button is clicked, I execute this javascript...

As I understand it, that does nothing to the underlying data. Instead, it calls the server-side grdPODetails_BatchEditCommand, at which point I manually update the data. In there, I'm updating the dataset that was initially loaded onto the page behind the scenes...

As you can see from my TODO, I'm unsure what to do if there's an error. Do I to put "e.Canceled = True", and if so, what does it do? Also, how can I tell the user what the error (ex.Message) is without a postback? (Or does this auto postback?) Assuming it doesn't postback, the best I can determine is to have a control on the form to write the error to in red font, but management doesn't like that idea. They'd rather I pop up an alert, but not sure that's possible.

Any suggestions? And am I going about this the right way to manually save the data?

Hi,

Do you have a signature control available in telerik?

If not signature, any control like a free form painting control to capture user mouse movements?

Thanks

Greetings!

I'm having an issue with a RadGrid using an EditFormTemplate; whenever I click my edit button on an item of this rad grid, the item goes into edit mode fine and my controls appear below them item. However, when the CSS for the row being in edit mode gets applied, it adds some peculiar artifacts to my grid. I get a blue line about 15 lines of text from the top of the item being edited. It's worth pointing out that the varchars being exposed by this grid are very large, which might have something to do with the issue; it only occurs when modifying an exceptionally long list of codes.

Please find attached screenshots of the problem behavior.

Screenshots include a before and after [edit button clicked] of the item in question, and the behavior exhibited.

It sort of hangs there, strangely in the middle of the original radgrid item. These elements don't appear to be actual controls; they seem to be part of a repeating background being applied by the CSS for an edit form item.

Here's my markup for the grid in question:

And here is the CSS which appears to be giving me trouble, pulled from dev console. The offending line is commented out. Disabling that attribute makes the coloration of the edit form item go back to default, but removes the garbage repeating x.

I can probably override it by "cancelling" the class in some way, but would honestly prefer it perform the coloration as it intends to, without the garbage.

Any assistance would be appreciated.

I i need to be able to access the text boxes within my form popup on rad grid I have tried the usual find controls but to no avail it always returns null. I cannot do it in itemDatabound as I am using a function in my dal which I need to pass the raw value to.

It is txtSubjectNotes.Text i require to access and Notes textbox Please can you advise also how can i close the popup from this button. Many thanks.

This is really minor, but in the example below, I get Visual Studio warnings that both Calendar and DateInput don't have runat="server". In looking online, I've seen examples where they exist and don't exist, so I'm assuming it doesn't matter. If that's the case, I'll add runat="server" to cut down on all my warnings, but I wanted to double check in case there's any reason not to include runat="server".
