I have a page with the UploadFile control on it, I was on Q2 and everything worked fine.

Just upgraded to Q3 and the control stopped working. When I click on the "Select" button nothing happens, I don't get the file browsing window.

Any thoughts?

Here's what I have on my page:

- radUpload
- radMultipage
- 2X radPageViews

Rare bug with with AutoPostback RadDock

Hi All,

I have a bug that is a bit strange and hard to reproduce. I think (not sure as I did not get the JS warnings) I was able to reproduce it on your demo site, here:
http://demos.telerik.com/aspnet-ajax/dock/examples/dynamicdocks/defaultcs.aspx

The steps to reproduce are:
- Dynamically created docks (with autopostback and Save/Load State).
- Click the header like crazy (about 10+ times)
- First I get a 'undefined' is null or not an object Line: 5869
- If I then try to move the dock, I get:
==========================================

[Solved] RadUpload Uploadedfiles collection EMPTY in IE(8) but not in Firefox

Hi,

Hi have a raduploadcontrol as below :

<telerik:RadUpload ID="RadUpload1" runat="server" AllowedFileExtensions=".jpeg,.gif,.png,.jpg"

ControlObjectsVisibility="None" OverwriteExistingFiles="True" AllowedMimeTypes="image/png,image/jpeg,image/gif">

</telerik:RadUpload>

File upload works perfectly fine in Firefox.

However when I try the same thing in IE it seems that there is no instance of the uploaded file available in the collection

Take a look at the firefox/ie images I've uploaded and you'll see what I mean.

For Each f As UploadedFile In RadUpload1.UploadedFiles



strNewMasterFilename = Server.MapPath("~/blogs/" & strActiveBlogName & "/" & strActiveBlogName & "_masterimage") & f.GetExtension

f.SaveAs(strNewMasterFilename, True)

Next

So Basically the radupload1.uploadedfiles collection is returning null in IE, and the correct value in Firefox (also works fine in Opera)

Does anyone have any ideas ?

Its driving me crazy.

ActiveSkill Tutorial - ASPNETDB.MDF

I do have a problem with this tutorial after all.

The steps in the ActiveSkill tutorial ask you to create a SQL db with .sql files provided in the courseware.

This all goes to plan.

I then modified my ActiveSkillUI projects web.config, adding a connection string and a couple of role/membership providers.

Those 3 things look like this.

<connectionStrings>

<add name="ActiveSkillConnectionString" connectionString=

"Data Source=NETDEV\SqlExpress;Initial Catalog=ActiveSkill;Integrated Security=True;User Id=ActiveSkillUser;Password=a0biozasu1"

providerName="System.Data.SqlClient"/>

</connectionStrings>

<system.web>

<roleManager enabled="true">

<providers>

<add connectionStringName="ActiveSkillConnectionString"

applicationName="/ActiveSkill"

name="RoleProvider"

type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>

</providers>

</roleManager>

<membership>

<providers>

<clear/>

<add name="AspNetSqlMembershipProvider"

type=

"System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

connectionStringName="ActiveSkillConnectionString"

enablePasswordRetrieval="false"

enablePasswordReset="true"

requiresQuestionAndAnswer="false"

requiresUniqueEmail="false"

passwordFormat="Hashed"

maxInvalidPasswordAttempts="3"

minRequiredPasswordLength="7"

minRequiredNonalphanumericCharacters="1"

passwordAttemptWindow="10"

passwordStrengthRegularExpression=""

applicationName="/ActiveSkill"/>

</providers>

</membership

>

etc etc...

Note I have a user login created for this database. That login is confirmed and working.

My problem is that despite the efforts above, the WSAT ASP.NET Configuration app, keeps creating and using an ASPNETDB.MDF db that it is annoyingly creating in my projects App_Data directory.

In an attempt to rid myself of this pointless database I tracked a reference to it back in the machine.config file.

In there it looked like this.

<add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>

So, as a test I removed this line and put my own connectionsting in there.

However running the WSAT app again, it gets the following error.

An error was encountered. Please return to the previous page and try again.

The following message may help in diagnosing the problem: The connection name 'LocalSqlServer' was not found in the applications configuration or the connection string is empty. (C:\Windows\Microsoft.NET\Framework\v2.0.50727\Config\machine.config line 152) at System.Web. etc etc

As a final check (before posting this thread) is I searched my project for any reference to the connection string LocalSqlServer and found it does not exist.

This it a mystery to me. Anyone have some tips?

Cheers

Brad

System.Data.DataRow dr;

for (int i = 0; i < 100; i++)

{

dr = dt.NewRow();

dr[0] = i;

dr[1] = "Package" + i;

dr[2] = i * 10;

dt.Rows.Add(dr);

}

RadGrid1.DataSource = dt;

RadGrid1.DataBind();

}

Setting DataXColumn for every Databound Series

Hi,

I'm trying to put together a line chart showing transactions per day over a period of time, separated out by store. I noticed that the dates on the X-axis are not correct when compared to the actual data. The dates on the bottom of the page don't scale, (instead it just uses each date point, so a hash mark can be one day, then jump to a week) and rather than place the datapoint at the right date, it just places it on the next one over.

When I set the DataXColumn setting for some hardcoded series, it worked fine. So, is there a way to set the DataXColumn for each series and have the chart display the correct dates? My code is below.

<telerik:RadChart runat="server" ID = "chartTransactions" AutoLayout="true" DataSourceID="datTransactions" DefaultType="Line" DataGroupColumn = "Store" Width="800" >

<ChartTitle><TextBlock Text = "Transactions - Store"></TextBlock></ChartTitle>

<PlotArea>

<XAxis DataLabelsColumn = "AppRejDate" >

<Appearance ValueFormat="ShortDate">

<LabelAppearance RotationAngle="270">

</LabelAppearance>

</Appearance>

</XAxis>

</PlotArea>

</telerik:RadChart>

<asp:SqlDataSource ID = "datTransactions" runat="server"

ConnectionString="<%$ ConnectionStrings:DBString %>" SelectCommand = "Select tblStore_Ref.Description, CAST(DATEADD(Day, DATEDIFF(Day, 0, AppRejDateTime), 0) AS Float) + 2 AS AppRejDate, Count(*) as Transactions From tblTransactionHistory INNER JOIN tblTransactionItems ON tblTransactionHistory.TransactionID = tblTransactionItems.TransactionID INNER JOIN tblStore_Ref ON tblTransactionItems.Store = tblStore_Ref.Store Where Status = 'A' AND AppRejDateTime Between @dateBegin AND @dateEnd Group By DATEADD(Day, DATEDIFF(Day, 0, AppRejDateTime), 0), tblStore_Ref.Description Order By AppRejDate, tblStore_Ref.Description">

<SelectParameters>

<asp:ControlParameter ControlID = "dateBegin" Name = "dateBegin" PropertyName="SelectedDate" />

<asp:ControlParameter ControlID = "dateEnd" Name = "dateEnd" PropertyName="SelectedDate" />

</SelectParameters>

</asp:SqlDataSource>

Some sample data:

40513   S-2   1
40518   S-2   2
40519   S-2   1
40549   S-2   4
40553   S-2   3

Thanks.

Retrieve Data from underlying Datarow

Is it possible to retrieve the underlying datarow when in any of the RadGrid Events, e.g. ItemDatabound? If this can be done can someone post an example.

From reading various posts it would seem that one would need to access the grid itself to get any data, though it seems rather an overhead to add a hidden column to the grid to have the data bound to it and then retrieve values from the grid. In my case I simply want to retrieve values from the datasource and build a tooltip for each row and I could do without the clutter of numerous hidden grid columns.

Thanks for any help.

Regards
Alan

GirdDateTime Column Max Date

I have been trying to get this to work forever now.. is there something that I am just not seeing.

I am trying to set the max date from the code behind and it's just not cooperating... yet everything else is.

Here's the code behind in the item_created method:

if (e.Item is GridEditFormItem && e.Item.IsInEditMode)

{

GridEditFormItem dataItem = e.Item as GridEditFormItem;

TableCell cell = dataItem["InspectionDate"];

RadDatePicker rdp = cell.Controls[0] as RadDatePicker;

rdp.Calendar.UseColumnHeadersAsSelectors = false;

rdp.Calendar.UseRowHeadersAsSelectors = false;

rdp.MaxDate = DateTime.Now;

}

any ideas would be great... basically it can figure out that the date is too large if you pick past the date, but when the calendar pops up, the dates past today are not grayed out... If I set the max date manually in the markup, it works fine.

please let me know if you need any more info.

Thanks,

Dustin

Using RadAsyncUpload to add files to a Sharepoint document library?

Hi

I'm working on a Sharepoint 2010 installation, and have had a bit of trouble using the ASyncUpload in a custom Visual WebPart.

I can add files to the RadUploadTemp folder fine, and in fact any folder on the 80 hive, but as far as I can tell there is no way to upload into the 14 hive. Is this correct?

In the past, I have used the standard ASP FileUploader, with an IO Stream to upload directly to the url of my Sharepoint Library, but this does not seem to work with the RAD Async Upload, I just get this error:

'http://local-sharepoint/TestLibrary' is not a valid virtual path.

If I browse to that URL normally it works fine, and works fine with a standard uplader.

Any ideas what's going on here?

Thanks for any help
