I'm using Subgurim's .NET control for Google maps. It works nicely except when I try to display more than about 15 markers on the map. In that case, it just displays "Powered By Subgurim(http://googlemaps.subgurim.net).Google Maps ASP.NET
Thanks on v3.2 to Comunactivo" in place of the map. Has anyone else experienced this?
This is in a Sharepoint webpart.
Here's the code in my CreateChildControls:
GMap1.ID = "GMap1";
GMap1.enableServerEvents = true;
GMap1.serverEventsType = GMap.ServerEventsTypeEnum.AspNetPostBack;
GMap1.MarkerClick += new GMap.GMap_Handler_ServerEvent_MarkerClick(GMap1_MarkerClick);
GMap1.Click += new GMap.GMap_Handler_ServerEvent_Click(GMap1_Click);
GMap1.enableHookMouseWheelToZoom = true;
Controls.Add(GMap1);
GControl control2 = new GControl(GControl.preBuilt.MapTypeControl, new GControlPosition(GControlPosition.position.Top_Right));
GMap1.addControl(control2);
GMap1.addControl(new GControl(GControl.preBuilt.LargeMapControl));
GMap1.enableHookMouseWheelToZoom = true;
GMap1.enableGKeyboardHandler = true;
And here's the routine to display the markers:
private void showEventsOnMap(DataTable dtEvents)
{
GMarker gm;
litNoMap.Visible = false;
GMap1.Visible = true;
GMap1.resetMarkers();
if (dtEvents.Rows.Count > 0)
{
double lat = Convert.ToDouble(dtEvents.Rows[0]["Latitude"]);
double lng = Convert.ToDouble(dtEvents.Rows[0]["Longitude"]);
GLatLng latlng = new GLatLng(lat, lng);
GMap1.setCenter(latlng, 8);
GLatLngBounds bounds = new GLatLngBounds(latlng, latlng);
string strHTML = string.Empty;
string myDate = string.Empty;
foreach (DataRow dr in dtEvents.Rows)
{
gm = new GMarker(new GLatLng(Convert.ToDouble(dr["Latitude"]), Convert.ToDouble(dr["Longitude"])));
myDate = Convert.ToDateTime(dr["EventDate"].ToString()).ToShortDateString();
strHTML = dr["City"].ToString() + ": (" + myDate + ") - " + dr["Summary"].ToString().Replace("\"", "");
GMarkerOptions go = new GMarkerOptions();
go.title = strHTML;
gm.options = go;
bounds.extend(gm.point);
GMap1.addGMarker(gm);
}
if (GMap1.getBoundsZoomLevel(bounds) >= 0)
GMap1.GZoom = GMap1.getBoundsZoomLevel(bounds);
GMap1.setCenter(bounds.getCenter());
}
string strCSV = (new Utilities()).GetTabDelimited(dtEvents);
dvGTD.Visible = false;
litNoMarkerInfo.Visible = false;
}
I tried adding the markers to the map directly. I also tried using a marker manager. Neither worked and the latter messed up my marker click event handling.
Any help would be appreciated.

I've added many more than 15 markers, so I know you can.
If you have a question about a specific control, ask the author, or ask people on a forum dedicated to that control. If it's a CP article, there's a forum under the article for questions.

The problem turned out to be a data issue. When there is an apostrophe in the GMarkerOptions.title property, the map won't display. My code now scrubs the data of apostrophes before assigning that property and, voila, a map with many more than 15 markers is displayed.

Suggestions please, on reporting libraries I can use in an ASP.NET web site to quickly produce many reports. I've busy looking at telerik tonight, but would like to look at several more in the next day or two.

What sort of reports ? Don't MS give away the Dundas ones now ?

Reports man, reports.  Tables of data with headers and footers, and grouping.
I haven't heard anything of the sort, being Dundas being given away.

hi guys n grls,
let me describe the issue. I have created the rdlc report, it has got one table and in that table there is one group and one detail. now what i want to do is add the serial number to the detail row.
I tried to use RowNumber(), it displays the number but not serially, I want a serial number listed serially.

HI
In your DataSet you get DataTable/TableAdaptor and their respective column. This/These Table/s act as just Skeleton to framework.
You can Add a column name SerialNumber (DataType System.Int(32), AutoIncrement True, AutoIncrementSeed 1, AutoIncrementStep 1).
After Build you can Get the SerialNumber field and you can use it in your report into the table.
Thanks

Hi guys I have noticed same result by trying two different approach.
1). I am simply opening a myfile.html inside a windows form and viewing it through the PrintPrviewDialog. What i have noticed is that if i change the text to some lite blue colour when i do a print preivew the colour isn't the same. It's blue but little dark. I am wondering if this is the default behaviour or is there any possible solution around to it. Has anyone ever noticed that.
2). simply open a html file inside a internet explorer having lite text colour. Do a print preview and u will colour aren't same.
What can be done to get the same colour while print previewing
Thanks in advance

I know you already asked this in another forum. The reason you're not getting answers is, the question is plain bizarre. A printer is never going to look exactly like your screen anyhow, so who cares if the blue is a little different ?
This has nothing to do with ASP.NET.

Thank you for confirming my suspicion. Thought I saw it yesterday.

Thanks for answering but I couldn't put my question any other way due to my vocabulary limitation. Perhaps you are write saying printer is never going to look exactly like my screen. It actually causes a huge confusion if you atleast try what i have mentioned on font color. But for sake of knowledge what is causing this problem, is that the way PrintPreview object being rendered or is that something internet explorer have some bugs.

Your screen has brightness and contrast controls. Given that you can CHANGE the colors on your screen, but not control the printer, it's absolutely true.
I have no idea why it happens. But, it's not really something worth worrying about.

Hello,
I have a DropDownList that is used above a gridview to filter the results of the gridview when the user selects a "package" in the DDL.
I am programitically adding a zero index item "All Packages" to the list on page load.
Selection of any item in the list fires the SelectedIndexChanged event and successfully runs the code need to filter the results.
However when I select the zero index "All Packages" item, SelectedIndexChanged event does not fire.
Any help is greatly appreciated.
VS 2008 C#
Inside an Update Panel
FrontEnd Code:
<asp:dropdownlist id="ddlPackageSelect" visible="true" runat="server" autopostback="true" xmlns:asp="#unknown"></asp:dropdownlist>
Backend Code:
private void PopulatePackageDropDown()
{
using (StoredProcedure sp = new StoredProcedure("GetPackageDropDown", "celebro"))
{
try
{
DataSet gh = sp.GetDataSet();
ddlPackageSelect.DataSource = gh;
ddlPackageSelect.DataTextField = "Name";
ddlPackageSelect.DataValueField = "Id";
ddlPackageSelect.DataBind();
if (sp.RC == (int)ReturnCode.SUCCESS)
{
ddlPackageSelect.Items.Insert(0, new ListItem("All Packages", "0"));
}
}
catch (Exception e)
{
lblMessage.Text = e.Message;
}
}
}
private void InitializeComponent()
{
this.ddlPackageSelect.SelectedIndexChanged += new EventHandler(ddlPackageSelect_SelectedIndexChanged);
}
protected void ddlPackageSelect_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlPackageSelect.SelectedIndex == 0)
{
BuildGlobalStylesheetList();
}
else
{
BuildPackageStylesheetList(int.Parse(ddlPackageSelect.SelectedValue.ToString()));
}
StylesheetDetail.Visible = false;
}

I was able to solve this one on my own. The problem was that I was Populating the dropdown on page load everytime. Moving the population of this drop down into a conditional if(!IsPostBack) took care of the problem.

Sounds like whatever you are doing the first time around, you are not releasing this excel file properly.
Are you building this excel file on the fly? Are you disposing of all your objects properly (look at using 'USING' blocks in your code)?

Hi,
I created a TextBox derivated class and I'd like to link it to a Label using a property, so here is what I need:
1) Create a property editor that shows a list of all available labels in the Page
2) Using the labels name, I need to get the UniqueID (ClientID), so I can use it with javascript.
Any tutorials about that?
Thanks,
Dirso.

hi,
Here is the code I've got so far, the ListBox works fine, but how do I populate it with the Labels? I can't access the Page object from it, right?
internal class LabelSelectTypeEditor : UITypeEditor
{
public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
{
return UITypeEditorEditStyle.DropDown;
}
public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
{
IWindowsFormsEditorService srv = null;
if (provider != null)
srv = (IWindowsFormsEditorService)provider.GetService(typeof(IWindowsFormsEditorService));
if (srv != null)
{
System.Windows.Forms.ListBox lb = new System.Windows.Forms.ListBox();
lb.Items.Add("test1");
lb.Items.Add("test2");
srv.DropDownControl(lb);
return lb.Text;
}
return value;
}
}
Thanks,
Dirso
