Q3 2011 (Version number: 2011.3.1115)

Problem: When adding items to OData-enabled controls (RadMenu, RadTreeView, RadListBox, RadComboBox) through design time erroneous markup is applied to the control:

<telerik:RadListBox runat="server" ID="RadListBox1">
    <Items>
    </Items>
    <WebServiceSettings>
        <ODataSettings InitialContainerName="">
        </ODataSettings>
    </WebServiceSettings>
</telerik:RadListBox>

Please note the added ODataSettings section. It will cause JavaScript errors on the page.

When I run my project I'm getting this error

Could not load file or assembly 'Telerik.Web.UI' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

In my web.config I checked that the version in the web.config is the same as the version I'm using in references

<assemblyIdentity name="Telerik.Web.UI" publicKeyToken="121fae78165ba3d4" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-2020.2.617.45" newVersion="2020.2.617.45" />

Hi

Im using Visual Studio 2022 and c#

I have a telerik RadGrid within my apsx page and I have set editMode="batch"

One of the columns SOStatus is a raddropdownList, with set items. When I select from the dropdown list and click on saveChanges within BatchEditCommand the SOStatus is blank, even though I have selected something. Not sure why?

Here is my ASPX

<telerik:GridTemplateColumn UniqueName="SOStatus" DataField="SOStatus" HeaderText="SO Status">
                                        <HeaderStyle Width="80px" />
                                        <ItemStyle Width="80px" />
                                        <ItemTemplate>
                                            <%# Eval("SOStatus") %>
                                        </ItemTemplate>
                                        <EditItemTemplate>
                                            <telerik:RadDropDownList ID="rdSOStatus" runat="server"  DataValueField="SOStatus" DataTextField="SOStatus" Width="110%">
                                                 <Items>
                                                        <telerik:DropDownListItem Text="" />
                                                        <telerik:DropDownListItem Text="Sale" />
                                                        <telerik:DropDownListItem Text="Pull Forward" />
                                                        <telerik:DropDownListItem Text="Risk" />
                                                        <telerik:DropDownListItem Text="Drop for this week" />
                                                        <telerik:DropDownListItem Text="Drop" />
                                                    </Items>

                                            </telerik:RadDropDownList>
                                        </EditItemTemplate>
                                    </telerik:GridTemplateColumn>

and here is the BatchEditCommand c# code

protected void rg_SalesPlan_BatchEditCommand(object sender, GridBatchEditingEventArgs e)
        {

            var batchEditingCommands = (List<GridBatchEditingCommand>)e.Commands;

       
            foreach (GridBatchEditingCommand batchCommand in batchEditingCommands)
            {
                Hashtable oldValues = batchCommand.OldValues;
     
                Hashtable newValues = batchCommand.NewValues;
         

             
                string SOStatus = newValues["SOStatus"].ToString();
               
                string OrigSOStatus = oldValues["SOStatus"].ToString();
               

}

Good afternoon,

I'm currently running Telerik UI for ASP.NET AJAX R3 2023.  I am using the RadAsyncUpload with a AsyncHandler.ashx to copy the file to a RadUploadTemp on a file share.

This has been working perfectly for ages but recently large file updates have been failing e.g. a 2.1 GB file failing at 61%.  I'm being told this is due to a TCP Zero Window issue.

I assumed the chunked upload mechanism mitigates the issues caused by TCP window size restrictions, which can cause slowdowns or failures when uploading very large files in a single request. I am setting the upload ChunkSize value to 4194304.

I have the following settings in web.config:

  <system.web>    
    <httpRuntime maxRequestLength="2097151" executionTimeout="18000"/>
  </system.web>

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength="4294967295"/>
      </requestFiltering>
    </security>
  </system.webServer>

Have you got any ideas as to why it might be failing for larger files, or what I can do to the configuration to prevent the TCP Zero Window error by pausing data transmission until the receiver is ready to accept more data?

Kind regards,

Richard

1. If there is any workaround we can implement using the current RadMenu to meet this requirement?
2. Whether there is an estimated timeline for when the RadMenu will support WCAG 2.2 natively?

Dear,

I use RadNumericTextBox with these options: 
 MinValue = 0
 MaxValue = 9999999
 NumberFormat.DecimalDigits = 2
 MaxLength = 10
 ShowSpinButtons = true

I see specific problem when I use any decimals. When I click on arrows (or type keyboard arrows) it increases/decreases by 1, but sometimes it stops on specific number (e.g. for 8.42 arrow down do nothing or for 63.42 arrow up doesn't work). I think there is a problem with javascript rounding and 8.42 - 1 is sometimes like 7.419999999999. It looks like a inner bug of the component.

Is it possible to format number first and make validation of length aftewards?
Is there any workaround for it?

Thank you

Hi

Im using visual studio 2019 .netframework using c#

I have a telerik Rad grid that is in Batch Mode and works great.  Within rg_SalesPlan_BatchEditCommand it goes through each edited row and does an update to the database, if one of the records fails to update the error message is added to a variable which collects any other errors. One finished in the foreach loop if any errors occured a popup alert is displayed with the errors.

My problem is once I click OK to the alert to acknowledge the errors, the grid refreshes but Im unable to continue editing any other rows, If I click on  a row nothing happen, until I click on Cancel or Save Changes button, then the grid goes back to normal.

Whats the best way to refresh the state of the grid so its back to normal please? 

Thanks

Good morning

Was there issues with any recent updated to Telerik?  I have just noticed that in Design View of my visual studio project, none of my Telerik RadGrds are displayed anymore.  Instead I get a control box on each grid with the error "Sysem.NullReferenceException"

Hi, I recently received a new laptop at work.  I was eventually able to compile and run both of my 2 applications in localhost, and deploy one of them to Dev and Prod.  However, I am having problems deploying my 2nd application. 

Again, it works fine in localhost.  When I deploy to the Dev environment, I get the error:

Could not load file or assembly 'Telerik.Web.UI, Version=2018.1.117.45, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

The version my reference points to is 2018.2.516.45.  So I don't know where the 2018.1.117.45 version is coming from, or why it is attempting to load this version.

Yes, I KNOW that this is an old version. If need be, I can probably upgrade to a newer version.  But if I can't figure out the version mis-match now, I think I will have the same problem with a newer version.  

Any help is appreciated.  

Thanks!
