WebGrid Community Server

Perhaps I'm overlooking a setting, but when I replace the native GridView with a WebGrid on a page using an ObjectDataSource, WebGrid generates columns for every method/property of the data object, even though I have defined a few columns in the <columns> key of the control.  The behavior is similar to the native GridView when "AutoGenerateColumns" is set to True.  Is there an equivalent property for WebGrid to recognize the column definition and not generate the additional columns?

Thanks for the help and the great tool!

I have noticed this as well since updating to the newest version.

You should use 'visibility' property to set the visibility for a column. You can set the grid's default column visibility by 'DefaultVisibility'

I hope this help you out.

Thank you for the response.  Setting the "DefaultVisibility" property of the grid to "None" and the "Visibility" property of each defined column to "Both" did hide the extra columns.  However, it appears that WebGrid is still calling all the properties and methods of the Data Object. As a result, the Data Object is performing a lot more work and taking longer to respond when using WebGrid versus the native GridView which only executes the methods and properties attributed with the defined columns.

I think this is a great tool and I'm looking forward to using it with my projects.

Hi, Do you how to show a dropdown in the web grid? I am binding the webgrid in code behind and not using any datasourceid in the aspx.

Any help will be appreciated.

Thanks.

No offense Vinny, but this is not the appropriate forum for this question and thread-hijacking is not appreciated.

Hi, I'm sorry about that.

That's true. You should set 'IsInDataSource=false' for these column you don't want to load :-)

Thanks for the reply.  The trouble is that WebGrid appears to be executing all the methods/properties of the DataObject and not just the few that are described in the design view.  Are you suggesting I explicitly add all the columns for the data object and set the IsIndataSource value to False for all the columns except the ones I want to show?

Thanks again!

Yes.

I don't know how many columns you have, but you could also do this in 'code-behind'. That way you don't need to set these in your aspx / ascx file.

I see the benefit by having a property to only load visible columns from the data source, and this should also be easy to implement in WebGrid.

Thank you for the clarification, I may begin replacing the GridView controls with your valuable tool in this way for the grids that use simpler Data objects.

I'll keep an eye out for an updated version of WebGrid.   Thanks again for your help and the use of WebGrid!
