Here is the code part which is giving me the issue:

Protected Sub ruCustomerImage_FileUploaded(sender As Object, e As FileUploadedEventArgs)
        'MsgBox("ruCustomerImage_FileUploaded", MsgBoxStyle.Information, "Murasalat")
        Dim updateImage As String = ", [Logo] = @Logo"
        Dim parameter As New Parameter("Logo", System.Data.DbType.Binary)
        SqlDataSource1.UpdateParameters.Add(parameter)
        SqlDataSource1.UpdateCommand = [String].Format("UPDATE FuneralHomes SET Logo = @Logo WHERE FuneralHomeId = '1000000'", updateImage)

    End Sub

Hi,

I cannot get any kind of information out of spreadsheet. sheet count is zero, I could not figured out how to access cells...

I load demo xlsx files but I cannot access any information. also there's not much in help section.

I am trying to get the value of a Radeditor field in a User Control when updating to store it in my database table

In the update command of my grid I have tried using both of these commands

Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim MyUserControl As UserControl = CType(e.Item.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)

Dim editorcomment As RadEditor
editorcomment = CType(MyUserControl.FindControl("Comment"), RadEditor)
editorcomment = editedItem.FindControl("Comment")

Neither of these commands brings back any data in editorcomment.Content

Please can you give me some code which will retrieve the Content of the RadEditor field

Wondering is there a way to add some arrows on the chart to make it look similar to the following info-graphics?

I have a RadGrid that I populate from my SQL database.  I use the RadGrid1_ItemCreated event to set the textbox width presently and that works fine.  Now I want to set a regular expression for the same textbox.  It is a textbox that contains an email address.  Here is my C# code:

protected void gvEmailRedirectMaint_ItemCreated(object sender, GridItemEventArgs e)
        {
            if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
            {
                string myMsg;
                GridEditableItem edititem = (GridEditableItem)e.Item;
                Regex regex = new Regex(@"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$");
                TextBox txtbx = (TextBox)edititem["RedirectEmailAddress"].Controls[0];
                txtbx.Width = Unit.Pixel(300);
                Match match = regex.Match(txtbx.Text);

                if(match.Success)
                    myMsg = txtbx.Text + " is Valid";
                else
                    myMsg = txtbx.Text + " is Invalid";
            }
        }

When I run this, it performs no editing.  If I click the update button, it saves the email address even though it is not in the proper format.  What am I doing wrong?
