grid binary image

[Chom]

Hi

Is there a way to get the MIME, Content Type and file name from the grid binary image when uploading a file to a database?

Hello Chom,

I guess you want to access the file properties in UpdateCommand of grid. If so you can use the following code snippet in order to achieve this.

C#:

    protected void RadGrid1_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        GridEditFormItem editItem = (GridEditFormItem)e.Item;
        RadUpload upload = (RadUpload)editItem["BinaryImage1"].Controls[0];
        string ContentType = upload.UploadedFiles[0].ContentType.ToString();
        string name = upload.UploadedFiles[0].GetName();
    }

Hi Shinu

Thanks for that tip, it helped me a lot. I was kind of on the right track, but I was in a different event.

many thanks

Helped me to. I put the data into hiddenfields and then used the hidden fields as control parameters

 Protected Sub RadGrid1_UpdateCommand(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.UpdateCommand
        Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
        Dim LogoImage As RadUpload = DirectCast(editItem("LogoImage").Controls(0), RadUpload)
        If LogoImage.UploadedFiles.Count > 0 Then
            Dim LogoContentType As String = LogoImage.UploadedFiles(0).ContentType.ToString()
            Dim LogoFilename As String = LogoImage.UploadedFiles(0).GetName()

            'copy values to cookies
            hfLogoContentType.Value = LogoContentType
            hfLogoFilename.Value = LogoFilename

        End If
       
        Dim SignatureImage As RadUpload = DirectCast(editItem("SignatureImage").Controls(0), RadUpload)
        If SignatureImage.UploadedFiles.Count > 0 Then
            Dim SignatureContentType As String = SignatureImage.UploadedFiles(0).ContentType.ToString()
            Dim SignatureFilename As String = SignatureImage.UploadedFiles(0).GetName()

            'copy values to cookies
            hfSignatureContentType.Value = SignatureContentType
            hfSignatureFilename.Value = SignatureFilename
        End If
       

    End Sub
