Hi Ranganathan,

OnCheckChanged is actually the server checked event.  Why not just define the checkbox as <input type="checkbox" onclick="test()" />?

Hi NewbApps,

You could try upgrading to the latest service release for your version to see if that resolves the issue.  Otherwise, we'd need a workbook that reproduces this problem.

Hi aschoi,

The objects are not the same on the client and the server.  On the client you should do the following

$util.addCompoundClass(currentRow.get_element(), "hiderow");

instead of 

currentRow.CssClass = "hiderow";

Your line of code just makes a property on the javascript object, but does not actually change the DOM element's className property.

Hi,

In this case, you may need to call whdg1.GridView.ClearDataSource() before applying the data source.

Well, if you have not created any columns in your code behind or defined them in the aspx, the Columns collection will be empty.  You'll need to define columns to access them in this way.  Another option would be to access the column (our internally stored one) off a cell of that column.  For example. 
grid.Rows[0].Items[0].Column.

HI,

If you were only autogenerating columns, you would have gotten a null ref exception or index out of bounds.  The problem is you did not type cast.  The indexer for Columns returns a GridField.  DataFormatString does not exist on this class.  You need to typecast to BoundDataField, UnboundField (if it actually is one) or the super class of both, FormattedGridField.

Hi whanes,

In the WebDataGrid, BoundDataField and UnboundField both have a DataFormatString that can be used to format how data is displayed.  For example:
this.WDG1.Columns[0].DataFormatString= "{0:c}";

Be warned that if you autogenerate columns, those are not available in the Columns collection.
