Adding a Checkbox column dynamically

[Dan Harvey]

Hello,

I have a radgrid and i have 4 static columns (Name, City, Zip, Country).  I want to add more columns, but i need to add these columns dynamically through code (because the number of columns will change).  I am having trouble figuring this out.  I was hoping there was a "GridViewCheckBoxColumn" like there is a "GridViewComboBoxColumn" but there isn't.  I wasn't able to find anything current in the forums and I was just wondering how to achieve this.  This is the code I have:

 

radGridView1.Columns.Add(new GridViewDataColumn

                                   {

                                        Header = "FullName",

                                        DataMemberBinding = new System.Windows.Data.Binding("FullName")

                                    });


//todo: all other columns

int numberOfColumns = 5; //Where 5 is the dynamically changing number

for (var ct = 0; ct < numberOfColumns; ct++)

{

    var cl = new GridViewDataColumn();

    cl.Header = contacts[0].Lists[ct].ListName;

    cl.DataMemberBinding = new System.Windows.Data.Binding("List" + ct);

    radGridView1.Columns.Add(cl);

}

 

Where I'm adding "GridViewDataColumn"'s I would like to add the Checkbox columns instead.
This is what my XAML looks like:
  

 

<UserControl x:Class="RK.CRM.MarketingList.MarketingList.MainPage"



xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"



xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

d:DesignHeight="300" d:DesignWidth="400" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">



<Grid x:Name="gridMain" Background="White" ShowGridLines="False" Loaded="GridMainLoaded">



<Grid.RowDefinitions>



<RowDefinition/>



<RowDefinition/>



</Grid.RowDefinitions>



<Grid.ColumnDefinitions>



<ColumnDefinition Width="*"/>



</Grid.ColumnDefinitions>



<telerik:RadGridView HorizontalAlignment="Left" Margin="24,117,0,0"

Name="radGridView1" VerticalAlignment="Top" Width="800" AutoGenerateColumns="false" />




</Grid>

</UserControl>

Please advise, thanks!!

Hi dan harvey,

If the data-bound property is boolean our default column (GridViewdataColumn) will automatically create a CheckBox editors for the respective fields. 

We have also introduced a GridViewCheckBoxColumn with our latest Internal Build from last Friday. If you download this build you should be able to utilize the new built-in column.

Thank you for your help, it looks like i was using a "ToString()" function on the end of my data that I was binding.

[Dan Harvey]

I want to try downloading this new internal build...what are the steps to installing this?  Is it documented on the website somewhere?

Thanks,

[Milan]

Hi dan harvey,

Just login with your account, go to "Your Account", then click Downloads which can be found on the top of the page, find the section related to RadControls for Silverlight, and finally click on Latest Internal Builds link.

Best wishes,

I should of been more specific, sorry.  I got that far, I downloaded the 00588RadControls_for_Silverlight_4_2010_1_0521_Dev.zip zip file from where you told me to.  Then the documentation i found on the website:

http://www.telerik.com/community/forums/winforms/general-discussions/how-to-install-internal-build.aspx

Tells me that the directions should be included within the zip file.  They are not there.  Do I add the assemblies to the GAC?  What do i do to install these files?

Thanks,

[Milan]

Hello Dan Harvey,

No need to add those assemblies to GAC. Just extract them somewhere on your machine and reference them from a project.

Kind regards,
