RadAsyncUpload in RadGrid

[Jagat]

Hello,

  I have a radgrid in one of the web pages and in the template column i am using RadAsyncUpload to upload the documents(including PDF). Saving the documents in the database is fine. My problem is with viewing the documents, after they are saved.  I saw in some threads that opening these pdf docs in seperate radwindow is a way to achieve this. How do i do that?  

1) Using the ExportPDF is the right way to do this?
2) RadBinaryImage still not supporting PDF  format?
3) How do i send the binary data of the document to the RadWindow?
4) If i have multiple rows in the grid, then, do i have to select the row first and then click on export pdf?
5) If the file size is 1 MB. Obviously, i don't want to save the document without compressing or resizing it. How do i do that without decreasing the resolution, Since the document will be pulled up for reporting purpose in the future?
6) When i click the export button now, a new window is opening with grid information in it. It is not showing the document.

Where am i doing wrong? 

string url, path = "";
       bool isExport = false;

       protected void Page_Load(object sender, EventArgs e)
       {
           url = String.Format("~/{0}.pdf", RadGrid1.ExportSettings.FileName);
           path = Server.MapPath(url);

       }


protected void RadGrid1_GridExporting(object source, GridExportingArgs e)
       {
           if (File.Exists(path))
           {
               File.Delete(path);
           }

           using (FileStream fs = File.Create(path))
           {
               Byte[] info = System.Text.Encoding.Default.GetBytes(e.ExportOutput);
               fs.Write(info, 0, info.Length);
           }

           Response.Redirect("~/frm_UploadDocs.aspx");
       }

       protected void RadToolBar1_ButtonClick(object sender, RadToolBarEventArgs e)
       {
           if (e.Item.Value == "Export")
           {
              //RadGrid1.ExportSettings.ExportOnlyData = false;
               isExport = true;
               RadGrid1.MasterTableView.ExportToPdf();
           }
           else if (e.Item.Value == "Delete")
           {
               if (File.Exists(path))
               {
                   File.Delete(path);
               }
           }
       }

 I followed the demo link below.

Any Help...??

[Ramkumar]

Can any one please say whether we can use RadAsyncUpload inside RadAjaxPanal??

[Shinu]

Hi Ramkumar,

It is possible to use a RadAsyncUpload inside RadAjaxPanel. Please have a look into the sample code snippet which works as expected.

ASPX:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" OnFileUploaded="RadAsyncUpload1_FileUploaded">
    </telerik:RadAsyncUpload>
</telerik:RadAjaxPanel>
<telerik:RadButton ID="RadButton1" runat="server" Text="Upload">
</telerik:RadButton>

C#:

protected void RadAsyncUpload1_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
{
    //This event will fire when the RadButton1 Click is happens
    //Uploaded filename
    string filename = e.File.FileName;
}

Thanks,
Shinu.

 Thank you. but I am using the RadAysncupload in Radgrid and the radgrid is place inside the RadAjaxPanal.

Hi Ramkumar,

Please have a look into the following code snippet which works fine at my end.

ASPX:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
    <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" AutoGenerateColumns="false"
        OnInsertCommand="RadGrid1_InsertCommand" OnItemInserted="RadGrid1_ItemInserted">
        <MasterTableView CommandItemDisplay="Top">
            <Columns>
                <telerik:GridBoundColumn DataField="OrderID" UniqueName="OrderID" HeaderText="OrderID">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="CustomerID" UniqueName="CustomerID" HeaderText="CustomerID">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="ShipAddress" UniqueName="ShipAddress" HeaderText="ShipAddress">
                </telerik:GridBoundColumn>
                <telerik:GridTemplateColumn>
                    <EditItemTemplate>
                        <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server">
                        </telerik:RadAsyncUpload>
                    </EditItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
        </MasterTableView>
        <ClientSettings Selecting-AllowRowSelect="true">
        </ClientSettings>
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

Thanks,
Shinu.

Hi Shinu,
  Here everything works well. But once I click the insert button, I find the RadAsyncUpload control with select button invisible.
also I tried with adding the handlers and everything. This is the problem I get. moreover the controls are in the ASCX page.

Hi Ramkumar,

Unfortunately I couldn't replicate the issue at my end. Please have a look into the full code which works fine at my end.

ASPX:

<uc1:GridAsyncUpload ID="GridAsyncUpload1" runat="server" />

ASCX:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
    <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" OnItemCommand="RadGrid1_ItemCommand">
        <MasterTableView CommandItemDisplay="Top">
            <Columns>
                <telerik:GridBoundColumn DataField="OrderID" UniqueName="OrderID" HeaderText="OrderID">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="CustomerID" UniqueName="CustomerID" HeaderText="CustomerID">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="ShipAddress" UniqueName="ShipAddress" HeaderText="ShipAddress">
                </telerik:GridBoundColumn>
                <telerik:GridTemplateColumn>
                    <EditItemTemplate>
                        <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server">
                        </telerik:RadAsyncUpload>
                    </EditItemTemplate>
                </telerik:GridTemplateColumn>
            </Columns>
        </MasterTableView>
        <ClientSettings Selecting-AllowRowSelect="true">
        </ClientSettings>
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

ASCX C#:

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.PerformInsertCommandName)
    {
        e.Canceled = true;
    }
}

Please provide your full code if it doesn't help.
Thanks,
Shinu.
