Many thanks for helping!

Error message during export when grid is grouped by a numeric column

I created a simple WebGrid based on your scenario. The grid columns are created dynamically at PrepareDataBinding server-side event.

string[] Profile1_Root = { "OrderID", "ProductID", "UnitPrice", "Quantity", "Discount" };
    
protected void WebGrid1_PrepareDataBinding(object sender, DataSourceEventArgs e)
{
    if (!IsPostBack)
        CreateStructure();
}

private void CreateStructure()
{
    foreach (string col in Profile1_Root)
    {
        WebGrid1.RootTable.Columns.Add(new WebGridColumn(col, col, col));
    }
}

After grid rendered, the root table is grouped by OrderID column (where this column is of int type column). The reported problem is not reproducible when try to export this to html.

For your information, I'm using following configuration in my local end to test the problem.

WebGrid 10.0.7200.24
WebUI.NET Framework 3.0.5000.975
IE 11 browser
CannotFindNumericColumn.aspx sample page (enclosed as attachment)

You may modify my sample if you find that the sample is not close to your scenario/code.

Error message during export when grid is grouped by a numeric column

Hello,

We use WebGrid 9.0.7200 in our project. All columns are created dynamically at runtime based on the current setup of our application.

When no grouping is applied or when we group by a character value column, export works fine. We have a problem when we group by a numeric column and then try to export. The message we get is:

Cannot find column 'acolumn'

where acolumn is the (numeric) column the grid is grouped by. As I mentioned above, it works ok when the grouped column is not numeric.

Any help would be appreciated,

Thanks
