Grid not populating

Not lucky getting RadGrid populated. I have a RadAutoCompleteBox where user can a code used as parameter of a stored procedure and the result should populate the grid in three columns. I tried to made it as simpler as possible but my grid is not showing up anything. 

My code ASPX:

<form id="form1" runat="server">
    <telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
     
    <telerik:RadAjaxManager ID="ajaxmanager1" runat="server" EnableAJAX="true">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="RadAutoCompleteBox1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadAutoCompleteBox1" LoadingPanelID="radloadingpanel1" />
                    <telerik:AjaxUpdatedControl ControlID="lblOEValue" LoadingPanelID="radloadingpanel1" />
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="radloadingpanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="btnSearch">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadAutoCompleteBox1" LoadingPanelID="radloadingpanel1" />
                    <telerik:AjaxUpdatedControl ControlID="lblOEValue" LoadingPanelID="radloadingpanel1" />
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="radloadingpanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>
     
    <telerik:RadAjaxLoadingPanel ID="radloadingpanel1" runat="server" AnimationDuration="0" InitialDelayTime="1000">
    </telerik:RadAjaxLoadingPanel>
     
    <telerik:RadAutoCompleteBox runat="server" ID="RadAutoCompleteBox1" ClientID="RadAutoCompleteBox1" >
        <!-- I supressed details because auto complete box is working fine -->
    </telerik:RadAutoCompleteBox>
     
    <telerik:RadGrid ID="RadGrid1" runat="server" autopostback="true">
        <MasterTableView AutoGenerateColumns="true">
            <Columns>
                <telerik:GridBoundColumn DataField="Description" UniqueName="Description">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="ConditionsAndOptions" UniqueName="ConditionsAndOptions">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="RetailPrice" UniqueName="RetailPrice">
                </telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>
     
    <asp:Button id="btnSearch" Text="Search" OnClick="btnSearch_Click" autopostback="true" runat="server"/><br />
     
    <div style="display:none">
        <asp:label ClientID="lblOEValue" id="lblOEValue" ClientIDMode="Static" autopostback="true" visible="true" runat="server" ></asp:label>
    </div>
</form>

 

My VB code:

Protected Sub RadAutoCompleteBox1_EntryAdded(sender As Object, e As Telerik.Web.UI.AutoCompleteEntryEventArgs)
    lblOEValue.Text = e.Entry.Text
End Sub
 
Protected Sub RadAutoCompleteBox1_EntryRemoved(sender As Object, e As Telerik.Web.UI.AutoCompleteEntryEventArgs)
    lblOEValue.Text = ""
End Sub
 
Protected Sub btnSearch_Click(sender As Object, e As EventArgs)
     Dim myConn As SqlConnection = New SqlConnection(ConfigurationManager.AppSettings("myconnection"))
    Dim adapter As SqlDataAdapter = New SqlDataAdapter
    Dim myDataTable As New DataTable
    adapter.SelectCommand = New SqlCommand("EXEC [dbo].[] '" + lblOEValue.Text + "'", myConn)
    myConn.Open()
    adapter.Fill(myDataTable)
    RadGrid1.DataSource = myDataTable

    myConn.Close()

End Sub

 

What am I missing here?

v2017.2.711.45 Error occurred during a cryptographic operation

Hi,

We've downloaded the latest version of the Telerik libraries - 2017.2.711.45 - and when we drop them into our web application we get the error

Error occurred during a cryptographic operation

with the stack trace pasted at the end of this message in our log files.

The error itself is pretty generic and suggested fixes include clearing the browser cache or tokens from the UserTokenCaches table. However, none of these solutions is working for us, so we've had to do a bit more digging.

What we've discovered is that this error is occuring on any page that uses the RadAsyncUpload control (we're not sure that it's only this control but other Telerik controls seem to be fine). It only happens with the 2017.2.711.45 libraries - if we copy back in the 2017.2.503.45 libraries our web application works again as normal.

We've tried recreating the problem in a simple web application but we can't and our real web application is far too complex to whittle down to demonstrable size.

Any help would be appreciated.

Stephen.

Web.UI.AjaxRequestEventArgs' is not defined

I know there have been previous similar old threads to this but I still keep getting this error message

Doesn't come up all the time but stops the project from building and therefore you cant run it

it always refers to the same sub on multiple pages

 

Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Web.UI.AjaxRequestEventArgs)

various lines of code....

End Sub

 

And on the pages in question, in page load I have the following:

 

Dim manager As RadAjaxManager = RadAjaxManager.GetCurrent(Page)
AddHandler manager.AjaxRequest, AddressOf RadAjaxManager1_AjaxRequest

The project is running the latest extensions (2020.2.617) and i have been through the upgrade wizard

ANY HELP?

 

really starting to be a pain in the back side!

Excel export cell formating not working

I have a RadGrid I'm exporting to excel but for cells with zeros it's not formating cell for Decimal with two places. I'm using the below to set the cell text and it works fine for Cell values other than Zero.

cell.Text = decValue.ToString("n2")

FilterExpression

Hi!

I want to swap a RadGridView with a RadListView Control.

One issue I have at them moment is applying a filter to the RadListView.

Before (with RadGrid) I used:

Dim filterExpression As String
            filterExpression = "(ProductID = " & drp_Products.SelectedValue.ToString & ")"
            RadGrid_Search.MasterTableView.FilterExpression = filterExpression
            RadGrid_Search.MasterTableView.Rebind()

How can I do the same thing with RadListVIew?

Thanks, Tom

There is a Telerik image container?

Hi!

I have a tiny rotating animation (GIF) to tell my users to wait while data is being retrieved, so I need to show or hide it depending on the situation.

I would like to know if there is an appropriated Telerik container that I could use to put my GIF inside and control its visibility from code behind I tried to use a regular DIV but it is not showing/hiding accordingly.

Thanks!

Radgrid: Problem extracting DataKeyValues from the DataSource
I am getting the following error: "There was a problem extracting DataKeyValues from the DataSource. Please ensure that DataKeyNames are specified correctly and all fields specified exist in the DataSource."

I can bind a dataset to my grid and that displays properly.  I have a master table with one detail table.  When I try to put one of the master table rows in edit via clicking on an edit icon in the row and displaying the details in an edit form template, that's when the exception is thrown.

As you will see the Mastertable datakeynames is CourseId which maps to the element name of the dataset.  Similarly the datakeynames is ChildCourseId for the GridTableView which also maps to the corresponding dataset.

I have looked at the documentation provided by Telerik and I believe I have coded the page correctly, but I am obviously missing something.  Any insight/suggestions would be greatly appreciated.

Below are snippets from the aspx page, followed by the code behind and the methods used to build the dataset that is bound to the grid.

Thanks,
Dan

Load RadPdfViewer dynamically in asp:PlaceHolder asp.net

Am trying to change old PdfViewer with Telerik control

This built as the following :

1. main Page (Attachment.aspx) load -> usercontrol (TransactionArchiving.ascx) //TransactionArchiving to deal with business

2. usercontrol (TransactionArchiving.ascx) load -> usercontrol (InboundArchive.ascx) //InboundArchive to deal with business

3. usercontrol (InboundArchive.ascx) load -> usercontrol (Archiving.ascx)  //Archiving usercontrol should support different type of attachments and should dynamically load the attachment (PdfViewer ,TextArea, Templates, Word and .....) each type built into different usercontrol

 

On bellow HTML for Archiving usercontrol 

<asp:Repeater ID="archivedTabs" runat="server" OnItemDataBound="archivedTabs_ItemDataBound">
         <ItemTemplate>
             <div id='<%#this.ClientID + "_viewT" + Container.ItemIndex.ToString() %>' class="tabContainer noBorder">
 
                 <div class="col-sm-12 lntext-Hdr">
                 </div>
                 <asp:HiddenField ID="hdnUniqueId" runat="server" />
                 <asp:HiddenField ID="hdnIndex" runat="server" Value='<%#Container.ItemIndex.ToString()%>' />
                 <asp:PlaceHolder ID="dynamicControlsPlaceHolder" runat="server"></asp:PlaceHolder>
                 <div class="rowF noRowColor noBorder" style="text-align: center">
                     <div class="col8">
                         <asp:Button ID="saveBtn" OnClick="saveBtn_Click" OnClientClick="return true;" CssClass="btn btnGreen loadingData" runat="server" meta:resourcekey="saveBtn" />
                         <asp:Button ID="deleteBtn" CausesValidation="false" OnClick="deleteBtn_Click" OnClientClick="return true;" CssClass="btn btnGreen" runat="server" meta:resourcekey="deleteBtn" />
                         <asp:Button ID="sendBtn" CausesValidation="false" Visible="false" CssClass="btn btnGreen" runat="server" meta:resourcekey="sendBtn" />
                         <asp:Button runat="server" ID="eibtnBackToDirectorateTray" OnClick="eibtnBackToDirectorateTray_Click" Style="display: inline;" meta:resourcekey="eibtnBackToDirectorateTrayResource1" class="btn btnGreen" CausesValidation="false" />
                         <asp:Button runat="server" ID="eibtnBackToOutboundDraftTray" OnClick="eibtnBackToOutboundDraftTray_Click" Style="display: inline;" meta:resourcekey="eibtnBackToOutboundDraftTrayResource1" class="btn btnGreen" CausesValidation="false" />
                     </div>
                 </div>
             </div>
         </ItemTemplate>
     </asp:Repeater>

I think the issue cuz of repeater and PlaceHolder (dynamicControlsPlaceHolder)

This is the C# code for the same userControl

PlaceHolder dynamicControls = item.FindControl("dynamicControlsPlaceHolder") as PlaceHolder;
PDFViewer ucPDFViewer = LoadControl("~/VIP/UserControls/ArchivingPDF/PDFViewer.ascx") as PDFViewer;
    ucPDFViewer.ID = "archivingControl_" + hdnUniqueId;
    ucPDFViewer.IsFromDirectorate = this.IsFromDirectorate;
    ucPDFViewer.CallDelete += new EventHandler(DeleteFromViewer);
 
 
    if (this.IsForManifest)
    {
        ucPDFViewer.loadManifest(record);
    }
    else
    {
        ucPDFViewer.loadData(record);
    }
 
    dynamicControls.Controls.Add(ucPDFViewer);

        Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider pdfProvider = new

        using (MemoryStream ms = new MemoryStream())

            pdfProvider.Export(document, ms);
            renderedBytes = ms.ToArray();
        }
    }
 
    // Workbook Documents
    else if (Regex.IsMatch(extention, ".xlsx|.csv"))
    {
        IWorkbookFormatProvider provider = null;
        Workbook document = null;
 
        switch (extention)
        {
            case ".xlsx": provider = new XlsxFormatProvider(); break;
            case ".csv": provider = new CsvFormatProvider(); break;
            default: provider = null; break;
        }
 
        document = provider.Import(e.File.InputStream);
 
        Telerik.Windows.Documents.Spreadsheet.FormatProviders.Pdf.PdfFormatProvider pdfProvider = new
      Telerik.Windows.Documents.Spreadsheet.FormatProviders.Pdf.PdfFormatProvider();
 
        using (MemoryStream ms = new MemoryStream())
        {
            pdfProvider.Export(document, ms);
            renderedBytes = ms.ToArray();
        }
    }
 
    RadLabel1.Text = "Displayed Document: <b>" + e.File.FileName + "</b>";
 
    RadPdfViewer1.PdfjsProcessingSettings.FileSettings.Data = Convert.ToBase64String(renderedBytes);
}

 

So the first image its the consol error (Capture01)

I have tried to update the code as the following (Capture02) // i think updated it wrong way

After code update (Capture03) 

This is the first time for me to implement telerik controls and i could not find fully document for all features needed (Custom buttons, Add png to the attached like signature).
