How could you replace the Column Headers with a Simple Caption?

I have a RadGrid with 2 columns, ID and Name. My MasterDetailTable shows Countries. and there is a nested table with exactly the same structure (ID and Name) and it shows the Cities.

The current behaviour is that I have all the columns appearing again for the nested table whereas I'd like to replace those columns with just a simple caption e.g. "Cities". The reason is that the ID and Name are already header texts of the MasterDetailTable.

I saw how to hide the header: http://demos.telerik.com/aspnet-ajax/grid/examples/client/scrolling/defaultcs.aspx

but how could I replace it with a simple caption?

TreeList: http://demos.telerik.com/aspnet-ajax/treelist/examples/firstlook/defaultcs.aspx also looks interesting and I may be able to use it but again I'd need a way to add Caption to the detail tables.

any help?

Thanks

Problem with exporting grid in loop

I have a sql-view which contains some simple data and also an column with an emailadres. When i click a button i want to send a mail to every distinct emailadres with an export of the view containing only the rows with that specific emailadres.

Everthing is going well except that the mails always get the same attachment! I guess it has something to do with the way I subcribe to the grid exporting event?

This is my code:

protected void rbTestMailVersturen_Click(object sender, EventArgs e) {

string query = "";

teller = 0;

SaveMailingForm();

RadGrid emailgrid = new RadGrid();

PlaceHolder1.Controls.Add(emailgrid);

//Fill a list with emailadresses

FillEmailadressen();

for (int i = 0; i < emailadressen.Count; i++) {

{

using (conn = new SqlConnection(ConnectionString)) {

conn.Open();

emailgrid.DataSource = null;

emailgrid.Rebind();

string ID = Request.QueryString["id"].PadLeft(2, '0');

query = "SELECT * FROM A_MAN_" + ID + " WHERE EMAILCOLUMN ='" + emailadressen[i] + "'";

SqlDataAdapter da = new SqlDataAdapter(query, conn);

DataTable dt = new DataTable();

da.Fill(dt);

emailgrid.DataSource = dt;

emailgrid.Rebind();

emailgrid.GridExporting += new OnGridExportingEventHandler(emailgrid_GridExporting);

switch (rcbExportType.SelectedItem.Text) {

case "CSV":

emailgrid.MasterTableView.ExportToCSV();

break;

case "Excel":

emailgrid.MasterTableView.ExportToExcel();

break;

case "PDF":

emailgrid.MasterTableView.ExportToPdf();

break;

case "Word":

emailgrid.MasterTableView.ExportToWord();

break;

}

protected void emailgrid_GridExporting(object source, GridExportingArgs e) {

string filename = DateTime.Now.Year + "-" + DateTime.Now.Month + "-" + DateTime.Now.Day + rtbOnderwerp.Text + teller + ".";

switch (rcbExportType.SelectedItem.Text) {

case "CSV":

filename += "csv";

break;

case "Excel":

filename += "xls";

break;

case "PDF":

filename += "pdf";

break;

case "Word":

filename += "doc";

break;

}

string path = Server.MapPath("~/" + filename);

using (FileStream fs = File.Create(path)) {

Byte[] info = System.Text.Encoding.Default.GetBytes(e.ExportOutput);

fs.Write(info, 0, info.Length);

}

MailMessage msg = new MailMessage();

MailAddress From = new MailAddress("info@xxxxxxxxxxxx.nl", "info@xxxxxxxxxxxx.nl");

msg.From = From;

msg.Subject = rtbOnderwerp.Text;

msg.Body = rtbMailtekst.Text;

msg.To.Add(new MailAddress(emailadressen[teller]));

teller++;

Attachment at = new Attachment(Server.MapPath("~/" + filename));

msg.Attachments.Add(at);

SmtpClient client = new SmtpClient("localhost");

client.Send(msg);

msg.Dispose();

FileInfo fi = new FileInfo(Server.MapPath("~/" + filename));

fi.Delete();

if (teller == emailadressen.Count)

Response.Redirect(Request.Url.ToString());

}

Hopefully anyone can help, that would be a lifesaver!

Thanks

Calculating pane dimensions properly

Hi all,

I am currently attempting to solve a small bug in my web project. The bug is that, in certain scenarios, the width is too large of a RadPane I have created programatically.

So, first off, the code that is causing the issue:

/// <summary>

/// Creates a RadSplitter and places the two panes it will hold onto it.

/// In addition, sets those panes dimensions such that they are appropriate for

/// the orientation of the RadSplitter.

///

/// I divide height and width in half because there are two panes.

/// </summary>

/// <returns> The rad splitter. </returns>

public static CormantRadSplitter CreateNewContent(Orientation orientation, RadPane parent)

{

Logger.InfoFormat("Creating new content to be placed upon: {0}", parent.ID);

CormantRadSplitter splitter = new CormantRadSplitter(orientation);

CormantRadPane firstPane = new CormantRadPane();

CormantRadDockZone firstDockZone = new CormantRadDockZone();

firstPane.Controls.Add(firstDockZone);

splitter.Controls.Add(firstPane);

CormantRadPane secondPane = new CormantRadPane();

splitter.Controls.Add(new CormantRadSplitBar(orientation, firstPane.ID, secondPane.ID));

CormantRadDockZone secondDockZone = new CormantRadDockZone();

secondPane.Controls.Add(secondDockZone);

splitter.Controls.Add(secondPane);

switch (orientation)

{

case Orientation.Horizontal:

firstPane.PanePosition = PanePositions.Top;

secondPane.PanePosition = PanePositions.Bottom;

//firstPane.Height = secondPane.Height = new Unit(parent.Height.Value / 2, UnitType.Pixel);

//firstPane.Width = secondPane.Width = parent.Width;

break;

case Orientation.Vertical:

firstPane.PanePosition = PanePositions.Left;

secondPane.PanePosition = PanePositions.Right;

//firstPane.Height = secondPane.Height = parent.Height;

//firstPane.Width = secondPane.Width = new Unit(parent.Width.Value / 2, UnitType.Pixel);

break;

}

return splitter;

}

The lines which are commented out are the culprits.

I believe the issue arises from 'fighting' with what Telerik/WebControls is trying to do. These panes are created with the intent of filling all the space they are given, but no more. The panes will do that by default -- their height and width properties are unset -- which causes them to use height/width: auto.

So, why do I have code which sets their height and width, then? My reasoning is that it is impossible to properly save the state of my page without explicitly defining the dimensions. If I execute the above code, with lines commented out, and then perform a hard refresh on the page -- the controls expect dimensions to regenerate with. If I leave them unset here, they will indeed figure out how to adjust themselves (they figure it out even if I DO tell them dimensions!) Unfortunately, the panes are resizable by the end user. If I do not save/load the dimensions of each pane then it is impossible to support persisting resized panes. (Not saving dimensions will cause each pane to take up half of its parents space assuming 2 panes regardless of how they were sized before refresh).

So, I am trying to setup each panes dimensions properly. I thought the above code did just that, but I am experiencing a little quirk! If I place a RadSplitter with vertical orientation on the page, then place a RadDock in the RHS pane, the RadDock spills out of the RadPane.

Here's an example image: http://i.imgur.com/4T8tu.png

In this image you will see a few things: An example where the RadDock is spilling out of the pane on the RHS, as well as an example where the RadDock stays contained inside of a horizontal-oriented splitter's pane. I am not sure why the horizontal one always seems to be fine.

Nevertheless, the issue seems to be pretty easy to see -- I just want to make the right decision. When I create that vertical splitter seen in the image -- the width of each pane (for example) is 502px. After a hard refresh and inspecting the pane elements on the page, I see that their widths have been changed to 499 and 500. These post-hardrefresh widths are appropriate, my calculated widths are not.

Is this just as simple as taking into account the width of the RadSplitBar being put onto the RadSplitter -- and subtracting that from the widths of each of the panes? If so, I wonder why the same issue does not occur with horizontal-oriented splitters? Also, the width of a splitBar isn't known at creation -- so I'd just be using a hardcoded width here.. a little scary.

Anyway, like I said.. I could probably force this solution pretty easily. I am just trying to understand -why- this is happening and what I can do to fix it properly in a way that's understandable to future developers -- not just a hardcoded number.

Thanks for your time

Overlapping tabs problem

dear all,

I am trying to add in pictures for the tabs, and want them to overlap (like the attached picture).

I use margin on all of them, so that they will squeeze together, and then use z-index to arrange them.

but the problem is the z-index only affects the first tab, the other 3 tabs does not arrange according to the z-index

I use C# (Telerik Version=2010.3.1317.35) and my code looks like :

AddTab("Account Info", true, "10");
AddTab("Enter Info", true, "8");
AddTab("Confirm Info", true, "2");
AddTab("Submit", true, "1");

private void AddTab(string tabName, bool enabled, string zIndex)
{
RadTab tab = new RadTab(tabName);

tab.Style.Add("margin-right", "-28px");
tab.Style.Add("position", "relative");
tab.Style.Add("z-index", zIndex);
tab.Enabled = enabled;
RadTabStrip1.Tabs.Add(tab);

I'm putting all the controlls to a Table control and adding to the page as follows at the RenderControl event.

Public Overrides Sub RenderControl(ByVal writer As System.Web.UI.HtmlTextWriter)

Dim panel As New Panel

Dim outerTable As New Table

outerTable = generateDynamicControls()

panel.Controls.Add(outerTable)

panel.RenderControl(writer)

MyBase.RenderControl(writer)

End Sub

When I adding simple ASP controls to this outer table, it is working fine.
But when I add Telerik Controls gives following error when it execute "panel.RenderControl(writer)" code.
Error:
Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

I'm using a Master page also.

Can u help me?
