Broken Image Showing on RadBinaryImage Rad Control

[Marlon Santos]

Hi,

I have a RadBinaryImage control inside a usercontrol and when the page loads, the image in the control appears "broken". This RadBinaryImage control is inside a usercontrol, which is in turn inside a RadGrid. I have the RadBinaryImage control in another page and it works fine. The only difference is that in the other page I use it in a RadGrid and not inside a usercontrol that is inside a RadGrid. Below are the code snippets.

 

<telerik:RadGrid ID="RadGridHardware" runat="server" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" DataSourceID="LdsHardware" OnItemCommand="RadGridHardware_ItemCommand" AutoGenerateColumns="False" OnItemCreated="RadGridHardware_ItemCreated" OnPreRender="RadGridHardware_PreRender" OnItemDataBound="RadGridHardware_ItemDataBound"> 
<MasterTableView DataSourceID="LdsHardware" DataKeyNames="ItemUID">  
    <EditFormSettings EditFormType="WebUserControl" UserControlName="HardwareDetails.ascx"></EditFormSettings>

    </MasterTableView>  
</telerik:RadGrid> 

 

 

 

The snippet for the HardwareDetails user control wher the RadBinaryImage resides is below:       

 

 

 

 

<tr>

<td style="width: 15%">  

<label> Image: </label>  

</td>

<td style="width: 85%">

<telerik:RadBinaryImage runat="server" ID="RadBinaryImageView" DataValue='<%# Eval("ImageContent") %>' AutoAdjustImageControlSize="false" Width="125px" Height="125px" ToolTip="" AlternateText="" />

</td>

</tr>

 

 

 

Please help. Thanks.

Marlon

Hello Marlon,

Unfortunately I'm unable to recreate such behavior using the provided details. I have attached a simple test page please give it a spin, maybe I'm missing something obvious.

All the best,

Hi Rosen,

Thanks for you response. Since I am still having this problem, I wanted to submit a zip file with all the pages involved in the probelm but I couldn't, so I submitted a support ticket (Ticket ID: 329491).

Thanks,

Marlon.

Hello Marlon,

Indeed I was able to observed the behavior you have described. In order to minimize memory consumption and improve performance of the control, the actual image data persistence is executed as late as possible (PreRender or Render) in control's lifecycle. However, in your scenario, as the control is not visible, those methods are not executed and the image data is not persisted.

In order to cover such scenarios, we have added a new property (PersistDataIfNotVisible), which to force data persistence if control is not visible. Therefore please download the next internal build in which this property should be available and give it a try.

Kind regards,
Rosen
