ArrayList

I have the following code which within I am trying to get the selected items into an arraylist which I then put into an email.

My code is adding items to the arraylist however, if more than 1 item is selected, then it duplicates the record with the first ID. so if i select row 3, row 4, row 5 then my output is:

row3, row3, row4, row5

Any ideas please

Protected Sub btnRequestFiles_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnRequestFiles.Click

If RequestFiles.SelectedItems.Count = 0 Then

lblNoFilesSelected.Text = "No files have been requested"

Else

lblNoFilesSelected.Text = ""

If String.IsNullOrEmpty(txtEmail.Text) Then

Dim dvEmailAddress As Data.DataView = GetEmailAddress.Select(DataSourceSelectArguments.Empty)

txtEmailAddress.Text = dvEmailAddress.ToTable.Rows(0)("EmailAddress")

Else

txtEmailAddress.Text = txtEmail.Text

End If

Dim FileID As Integer

Dim ArraySelectedFiles As New ArrayList

For Each item As GridDataItem In RequestFiles.MasterTableView.Items

If item.Selected Then

Dim Filename As String = item("FileNumber").Text.ToString()

Session("FileID") = Filename

ArraySelectedFiles.Add(Session("FileID"))

FileID = Convert.ToInt32(item.GetDataKeyValue("FileID"))

'Grab the objects out array and put into string.

For Each objitem In ArraySelectedFiles.ToArray

Session("PropertyString") = Session("PropertyString") & objitem.ToString

lblArrayList.Text = Session("PropertyString")

Next

Dim conFiles As SqlConnection

Dim strConnection As String

Dim cmd As New SqlCommand

Dim cmdinsert As SqlCommand

Dim strInsert As String

strConnection = ConfigurationManager.ConnectionStrings("FileawaySQLConnectionString").ConnectionString

conFiles = New SqlConnection(strConnection)

conFiles.Open()

cmd.Connection = conFiles

cmd.CommandText = "UPDATE dbo.Files SET FileStatus = 2 WHERE FileID = '" + FileID.ToString() + "'"

cmd.ExecuteNonQuery()

conFiles.Close()

conFiles = New SqlConnection(strConnection)

strInsert = "INSERT INTO dbo.FileHistory (FileID, Action, ActionedBy) VALUES (@RowID, @Action, @ActionedBy)"

cmdinsert = New SqlCommand(strInsert, conFiles)

cmdinsert.Parameters.AddWithValue("@RowID", FileID)

cmdinsert.Parameters.AddWithValue("@Action", 2)

cmdinsert.Parameters.AddWithValue("@ActionedBy", txtEmailAddress.Text)

conFiles.Open()

cmdinsert.ExecuteNonQuery()

conFiles.Close()

End If

Next

Me.RequestFiles.Rebind()

send_email()

End If

Session.Remove("PropertyString")

End Sub

Mark row selected based on a field

Hello,

So I need to put information on a grid that has the following structure:

SampleNumber(varchar20)
Date(DateTime)
Notes(text)
IsValid(bit)

the last column (IsValid) does not need to be visible, but if it is set to false, then that particular row needs to be selected. No checkbox or command buttons are needed, the row will be selected only if IsValid == false, hence, everything has to be server side.

Any hint will be appreciated, thanks!

Radconfirm before radwindow closes only if any values changed in the radwindow

Dear Team,

I want to achieve the below.

I have a parent page which displays the details about a project. From this, on a button click , I open a radwindow which displays some specific details about the project which displayed in the parent window. The radpopup window has some textboxes and other controls with values along with a UPDATE button.

What I need is, if I change values in the popup and try to close the radwindow without update, it should ask me a confirmation that” Are you sure to close this window without updating your data? The changes will be lost!! Click on CANCEL to return to the window and update". If i try to close the popup radwindow after updated [ie,if I not changed any values after updated] or without any change, it should not ask the confirmation before close the radpopupwindow.

Please help me to achieve this.

Can't find OnRequestStart property on RadGrid

Hi,

I am trying to use the logic described in this article (http://www.telerik.com/help/aspnet/grid/radgrid-telerik.webcontrols.gridclientevents-onrequeststart.html) in my RadGrid. I have it set up as follows:

<ClientSettings EnableRowHoverStyle="true">

<Selecting AllowRowSelect="True" UseClientSelectColumnOnly="True" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="False" />

<ClientEvents OnRowSelected="PaymentLedgerRowSelected" />

<ClientEvents OnRequestStart="ThisEvent" />

</ClientSettings>

But I am getting the following error:

Validation (ASP.NET): Attribute 'OnRequestStart' is not a valid attribute of elements 'ClientEvents'.

And when I run the code, I get the following error:

Type 'Telerik.Web.UI.GridClientEvents' does not have a public property named 'OnRequestStart'.

Am I missing something?

Thanks,
Jerry

Folder Permissions?

I am currently using the RadFileExplorer in conjunction with a CustomFileSystemProvider (Hooked to a network share, base on a demo I found here). And while I can upload and download files just fine, it appears that creating folders, renaming items, and deleting items all fail. Deleting told me the application did not have sufficient permissions. What permissions are required? I tried setting the folder up for access to Everyone with Full Control, but that did not seem to help. I even attempted to setup the web to run as the local machines Administrator, but still no luck. Any ideas?

Setting various control BackgroundColor's OnClientDragging

Hi All,

I am attempting to achieve the following functionality: I would like to change the background color of the control the user's mouse is currently over when the user is dragging an item.

Reasoning: I allow the user to drag-and-drop items from a RadListBox onto the page. This drag-and-drop functionality creates RadDocks. Once a RadDock is on the page it set's its RadDockZone is forbidden to all other docks. As such, if I had two docks on the page, I indicate that a 3rd RadDockZone is a viable move option by changing that DockZone's background color to green. I would like this functionality to extend to when the user is first creating their RadDock -- I would like DockZone currently being hovered-over to turn green.

Is this possible? I'm looking through the OnClientDragging event, and I can see that it can return (X,Y) coordinates through use of the get_domevent() method. Is there a way to translate this hit coordinate into the control located at the coordinate?

Thanks for your time,

Sean Anderson

Modal Pop up extender

Hi All,

I am adding comments to the database by opening the modal pop up extender. User can type the comment in the modal pop up text box and as soon as the user clicks Ok button, the comments go to the database, and i pull those saved comments from database and display them in the grid.
Everything works fine except when I put the ajax panel around the Ok button, the display of the saved comments stopped right away. I am not sure what am I doing wrong. Below is my code

<asp:LinkButton ID="lnkComments" runat="server" Text="Add Comments"></asp:LinkButton>

<div>

<asp:Panel ID="panel1" runat="server" CssClass="modalPopup" Style="display: none"

Width="500px" BackColor="#E6E6E6">

<p>

Please add the comments</p>

<asp:TextBox ID="txt_comments" runat="server" TextMode="MultiLine" Width="480px"></asp:TextBox>

<div>

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel_Ok" LoadingPanelID="RadAjaxLoadingPanel1">

<asp:Button ID="OkButton" runat="server" Text="OK" OnClick="OkButton_Click" CommandName="Ok" />

<asp:Button ID="CancelButton" runat="server" Text="Cancel" />

</telerik:RadAjaxPanel>

</div>

</asp:Panel>

</div>

<div>

<asp:ModalPopupExtender ID="ModalPopUp_Comments" runat="server" TargetControlID="lnkComments"

PopupControlID="panel1" BackgroundCssClass="modalBackground"

CancelControlID="cancelButton" DropShadow="true">

</asp:ModalPopupExtender>

</div>

and the code behind is

protected void OkButton_Click(object sender, System.EventArgs e)

{

ModalPopupExtender ModalPopUp_Comments = (ModalPopupExtender)RadGrid_cDetailsView.MasterTableView.Items[0].FindControl("ModalPopUp_Comments");

TextBox txt_comments = (TextBox)RadGrid_cDetailsView.MasterTableView.Items[0].FindControl("txt_comments");

RadGrid RadGrid_cComments =(RadGrid) RadGrid_cDetailsView.MasterTableView.Items[0].FindControl("RadGrid_cComments");

ModalPopUp_Comments.Hide();

cComments comments = new cComments();

CiscHeader cHeader = new CiscHeader();

cHeader.cId = Request.QueryString["ID"];

if(txt_comments.Text != "")

{

//comments.UserId = HttpContext.Current.User.Identity.Name;

// for testing purposes only

comments.UserId = "Anjali";

comments.UserComment = txt_comments.Text;

}

cHeader.AddcComments(comments);

cScoringCtrl cscoringCtrl = new cScoringCtrl();

cscoringCtrl.savecComments(cHeader);

txt_comments.Text = string.Empty;

cHeader.cComment.Clear();

cscoringCtrl.getcComments(cHeader);

RadGrid_cComments_Bind(cHeader, RadGrid_cComments);

}

radGrid_cComments_Bind , refreshes the gris and shows the user comments right away.

Any help will be appreciated.
