I am finally getting this to work the way I want. For some photos it works perfectly. I use a browse button to select the image, click upload and it populated the image editor with that image. I can then use the save icon in the toolbar to save the image and close the RadWindow the ImageEditor is in. 

 

The strange part is for a few images that does not work. I can browse, select and upload the image, but the save portion does nothing. The upload shows the green dot, so the image file is valid. It is even uploaded into the temp directory. So why would the save code not fire for certain images. I can consistently reproduce what images it is for.

It is not the file size as one of the ones with an issue is smaller than one that works fine. 

Any Ideas?

Hi,

I have used load on demand functionality to bind the items to radTreeList. Now my problem on this list I have a functionality that I have links aginst the items and on click of that it opens a popup window which have ok Button. so on click of this ok button some action is done and post back is done and whole data is binded to radTreeList but in collapsed mode.

Here my requirement is to show the only that child item in expanded mode which we performed the action in previous step after the postback.

 

 

Thanks,

Ram

I have 3 buttons on my page and when I hover over them I want to return a service that pops up the information via a service.  Is it possible to hover over and asp button and then return a special Id to the service to then look up information or is this a bridge to far.

 

<tr>
                                <td style="font-size: 12px; border: 1px inset lightgray; border-right: none; font-weight: bold; font-family: Arial">UTA</td>
                                <td style="border: 1px inset lightgray; border-left: none">
                                    <asp:ImageButton ID="imgUTA" runat="server" Height="28px" Width="28px" /></td>
                                <td style="font-size: 12px; border: 1px inset lightgray; border-right: none; font-weight: bold; font-family: Arial">APFT</td>
                                <td style="border: 1px inset lightgray; border-left: none">
                                    <asp:ImageButton ID="imgAPFT" runat="server" Height="28px" Width="28px" /></td>
                                <td style="font-size: 12px; border: 1px inset lightgray; border-right: none; font-weight: bold; font-family: Arial">Admin</td>
                                <td style="border: 1px inset lightgray; border-left: none">
                                    <asp:ImageButton ID="imgAdmin" runat="server" Height="28px" Width="28px" /></td>

Hi,

I'm experiencing a weird problem related to RadAjaxManager on a SharePoint 2103 layout page. From time to time (it seems quite random) "ajaxified" buttons (i.e. the ones under control of RadAjaxManager) issue a full postback instead of a partial AJAX request. As a result, values entered on a form (in text boxes, drop-down lists etc) are lost because the entire page is pull out from the server. This is a really bad user experience.

I did my research and it seems that disabling Forms Authentication in IIS of my SharePoint web application fixes the issue. The question is why does it fix the problem? I don't understand how RadAjaxManager can be related to Forms Authentication. I have to explain that to my client.

Thanks,
Leszek

Anyone have any experience with integrating Google fonts available from http://fonts.googleapis.com with Telerik's AJAX controls?  I've got a client who's wants to use these fonts instead of the fonts built into the various skins. Tips would be welcome.

Hello,

We are facing this issue currently in chrome browser wherein, whenever the font-size/font-family is changed from dropdown, it is not reflected for the text we enter thereafter rather penultimate font-size/font-family is considered. This works fine whenever we select the text first and apply the changes.

To add to this, we have recently upgraded to Telerik ASP.Net Editor v.2015.2.729.45. This seems to be common issue across community, but none of the proposed solutions worked for us.

Also, same issue is reproduced at http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx demo page.

Can you please look into this issue?

Thanks,

Muktesh

I have wasted almost 20 hours over this. 

My grid was not binding data when I used NeedDataSource. When I used Basic DataBinding on PageLoad/PreRender, My Item command event fired, but Delete Command event handler didn't and showed this error:

"" Uncaught Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. â€‹
Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.​  ""

For that I had to use NeedDataSource as I read on forum that we need to use NeedDataSource for that. When I used NeedDataSource my grid didnt show any data.

My grid is in a RadTabStrip. At first when the page is loaded, the grid tab is not selected. However the NeedDataSource executes & sets DataSource to null because a reuired queryString value is not present on first page load. Then I append a queryString value and press enter, again NeedDataSource gets called & this time binds the grid with the queryString parameter, however the RadTabstrip that contains the grid is still not selected and some other tab is selected on page load. Now when select the tab that contains the grid, NeedDataSource doesnt get called, and there s nothing in place of the grid (The grid is not bound to any data).  

 

I wasted so many office hours on this, but to no avail. I created a separate sample project for you to assess, however the issue did not occur in that sample. And trust me when I say this, I replicated each and everything in that sample, each and every property was exactly the same as was in my initial project, but in the sample the Grid showed data, I even replicated the RadTabStrip process to ensure that the events get called in exactly that same manner.

 

The Soultion:

Just 5 minutes ago I set MasterTableView's EnableViewState property to false. This solved the problem, Grid gets bond with data, NeedDataSoruce gets called everytime, Delete & Item Command event handler execute just fine. BUT in my sample project, I did not set EnableViewState=false of MasterViewTable tag. 

Why wasnt the issue replicated in that project & why is this absurd behavior happening? Too much time wasted for just a petty issue, setting one property made it work in one project, however in another project the issue didnt occur at all. What is the possible reason kindly elaborate. What is the drawback of using EnableViewState = false of masterViewTable other than hitting the DB every time & is there any other way than setting ViewState to false.

 

Regards,

Zepp.
