Serverside RowClick event handling for RadGrid

Here are a few steps to handle an event on the server side for Telerik's RadGrid

1. Add attribute OnItemCommand to <Telerik:RadGrid>, for example "OnItemCommand="radGrid1_ItemCommand" if your grid name is radGrad1
2. Add attribute EnablePostBackOnRowClick="true" to <ClientSettings>
3. To your code behind, add the following, which will assign a specific cell value to a string:

protected void radGrid1_ItemCommand
{
    // this block will take the value of the column "ContactName" from the grid and assign it to a string
    if (e.CommandName == "RowClick")
    {
        int index = e.Item.ItemIndex;
        GridDataItem item = (GridDataItem)radGrid1.Items[index];
        string contactName = item["ContactName"].Text;
    }
}

Registering Telerik.Web.UI when used in a webpart

Quick post about another problem I stumbled across. My team decided to proceed using Telerik controls for our webparts. I ran the .msi and installing went just fine.

Also in VS, I immediately noticed the extended Toolbox with all the awesome new controls so I wanted to horse around with the RadGrid to see how it works.

So I created a new webpart in my project and drag-n-dropped the RadGrid control onto the web user controls. It added the following two lines of code:

And added the related assembly to the bin folder of my project and a reference.

But then BOOM! Big fat ass exception thrown; complaining that it cannot find the Telerik.Web.UI assembly

This is how to solve it.

First, go to your Package\Packge.package file, open it and go to Advanced (at the bottom). Next, click 'Add'->'Add existing assembly...'. Find the dll and then add a new item to the Safe Controls section, where you fill out the Namespace and the Assembly Name. Make sure that the Deployment Target is set to the GlobalAssemblyCache

Then, open the VS Command Prompt, and execute the following command line:

sn -T fullpathtoyourassembly



This wil give you the PublicKeyToken which you will use in a minute. Close the prompt and go to the folder where your dll is residing. Right-click it, choose properties -> Details and take note of the File version:

Finally, go back to the .ascx file and in the Register element, extend the Assembly attribute with the following:

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI, Version=2011.3.1115.35, Culture=neutral, PublickKeyToken=121fae78165ba3d4" %>

That should make it work!

Enjoy ur weekend!

Namespaces and class declarations in a webpart

Using LINQ to order an ASP.NET DropDownList

How LINQ can you save you from writing many lines of code. Easy stuff:

protected void SortDropDownList(DropDownList ddlToSort)
{
    ddlToSort.DataSource = ddlToSort.Items.Cast<ListItem>()
                            .OrderBy(o => o.Text)
                            .ToList();
    ddlToSort.DataBind();
}

Passing on ViewState Items onto ObjectDataSource

Because the datasource instance does not run in your page instance, you will not be able to fetch your ViewState items. The only way to do this is to pass it on to the parameters. Suppose you've got a gridview, using an object data source instance called 'odsBand' and you would like to retrieve a DataSet from your db filtered by band name. In this case you need to define a electParameter which will hold the band name retrieved from your ViewState. See markup below

<asp:ObjectDataSource ID="odsBands" runat="server" 
    SelectMethod="SelectBands" 
    OnSelecting="odsBands_Selecting"
    OnSelected="odsBands_Selected"
    OnFiltering="odsBands_Filtering"
    &lt;SelectParameters>
        <asp:Parameter Name="BandName" Type="String" />
</SelectParameters>
</asp:ObjectDataSource>

Here I set up the BandName property which will chuck the request band name string into the ViewState:

private string BandName
{
    get
    {
        return ViewState["BandName"] == null ? "" : ((string)ViewState["BandName"]);
    }
    set
    {
        ViewState["BandName"] = value;
    }
}

In the Page_Load method, I'm putting the QueryString into the Viewstate, using the BandName property:

protected void Page_Load(object sender, EventArgs e)
{
    odsBands.TypeName = this.GetType().AssemblyQualifiedName;
    
    if (!Page.IsPostBack)
    {
        BandName = Request.QueryString["bandName"];
        // This is my SPGridView instance which will display the data
        grdBand.DataSourceID = "odsBands";
    }
}

Ok cool. From here I use the property to set the input parameter 'BandName' like this:

protected void odsBands_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
{
    e.InputParameters["BandName"] = BandName;
}

Finally, I define the SelectMethod 'SelectBands' with one string argument which is the input parameter. In this particular case I'm using a DataSet from which I then create a DataView to filter on the parameter value:

public DataView SelectBands(string bandName)
{
    // The method below fetches the data from a db, replace this with your own source
    DataSet dsBands = BandsResourceManagement.Instance.GetBands();
    
    // BandName is also the field name in the table and I'm sorting the records by the field BandId
    DataView dvBand = new DataView(dsBands.Tables[0],"BandName = '" + bandName + "', "BandId", DataViewRowState.CurrentRows);
}

Connecting VS2008 to TFS2010

What a hassle. My virtual machine crashed today and it got reset to the last snapshot, which had been taken like somewhere in 1957. So I've practically wasted all day on reconfiguring all the crap that I had installed after the snapshot was taken.

One of the things I spent a fuck load of time on was getting VS2008 connecting to TFS2010. Finally, got it to work. This is how:

1. I installed VS2008
2. Then downloaded and installed Microsoft Visual Studio 2008 Service Pack 1 (Installer), get it here
3. Then, downloaded and installed Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 (Installer), get it here
4. Checked in VS2008 if it installed correctly

Finally, I drilled down into the registry, to "HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\TeamFoundation\Servers" (you should be able to find it, if not make sure you installed the earlier mentioned stuff in the correct order).

In here, I added a string value where the value name can be anything and the value data field should contain the full address of your server.

From here, you should be able to go to the Team Explorer window in VS and add the team project. That's it.

Note2Self: Configuring web service for web application usage

Entries to web.config in WSS/VirtualDirectories/80 to configure webservices
Steps:

1 Add 'endpoint' element to 'client':

<client>
   <endpoint address="http://localhost/YourService/ServicesYou.asmx"
             binding="basicHttpBinding"
             bindingConfiguration="###MyCustomBindingName1###"
             contract="###DefinedConfigurationName###"
             name="###stringEndPointConfigurationName###" />
</client>

###MyCustomBindingName1### -- is a reference to what will be added to the system.serviceModel/bindings/basicHttpBinding/ element. Preferably, prefix it with the binding type (i.e. in this case: "basicHttpBinding_MyCustomBindingName1")

###DefinedConfigurationName### -- should be the value that you defined in the Reference.CS file. To be more specific in the attribute before the interface definition:

[System.ServiceModel.ServiceContractAttribute(Namespace = "http://WebServices/", ConfigurationName = "###DefinedConfigurationName###")]    

2 Create binding element

        <binding name="###MyCustomBindingName1###" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
          <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>

I changed the maxReceivedMessageSize and maxBufferSize to the max. allowed size since I had trouble retrieving large DataTables.
