calling javascript function from Silverlight app

[Brian Graves]

I've programatically created a column with a button in my RadGridView and have created an event handler for the button click: 

 

public class GridViewImageButtonColumn : GridViewHyperlinkColumn

 

 

 

{

 

 

 

    public override FrameworkElement CreateCellElement(GridViewCell cell, object dataItem)

 

 

     {

 

        Button btn = new Button();

 

 

         btn.Click +=

new RoutedEventHandler(btn_Click);

 

 

 

 

 

        return btn;

     }

 

I even found out how to call the pages javascript by using this code in my click event handler:

    void btn_Click(object sender, RoutedEventArgs e)

 

 

     {

 

 

         HtmlPage.Window.Invoke("jsfunction", new string[] { rowData });

 

 

    }
}

However, I'm not sure how can I get the the RadGridView row data from the row that the button was clicked in. 

Questions:
1)  how do I find out which row number that I clicked on?
2)  how do I access each cell's data from each column in the row that I clicked?

Hello,

Since the button is inside the row you can use DataContext property - just cast it to your object type and access desired property. You can use also this.DataControl.Items.IndexOf(((Button)sender).DataContext) to find the item index.

Thanks but could you provide a C# example for the first thing you said (just cast it to your object type and access desired property)?  I'm not sure what object you are referring to.  How do I get the data from each column (specifying the name or column index)?

Hello,

You can try the code in your Button Click event handler. Sender argument is your button and DataContext of your button is your data item.

All the best,
