Binding an empty dataset to ultrawebgrid
posted

How do I handle grid binding when the dataset is empty?

I get an error at UltraWebGrid.OnLoad() when datasource is empty.

"The IListSource does not contain any data sources."

    Assuming you are using the System.Data.DataSet object.

    I would assume that you could just take your DataSet object and see if you don't have any tables in it before calling databind.

     

    if (ds.Tables.Count > 1)

    webgrid.DataBind()

     

     The behavior is similar to that of the GridView, they both will throw the same exception as it tries to bind.

    I found the problem.

    I had set Dataset = new dataset().

    So when there was no dataset, new Dataset() was passed, in other words zero was passed.

    I set Dataset to return null when there is no data. Its worknig fine.
