Hide Column with datasource assigned at runtime (columns.count always 0)
posted

Hi There!

I am assigning a dataset at runtime to a webgrid's datasource (in designer the datasource is blank).

 

 

 

 

Me.WebDataGrid1.DataSource = DS
Me.WebDataGrid1.DataMember = "orders"
Me.WebDataGrid1.DataBind()

Grid shows correctly, no problem.

Now I want to hide two columns, but the me.Webdatagrid.Columns.Count is always 0.
I tried with AutoGenerateColums set to True, set to False no way to get the columns in the collection.
The .rows.count property shows the exact numbers of rows,

So I can't hide a columns because

Me.WebDataGrid1.Columns.FromKey("GUID").Hidden = True

 

returns an error becaus the columns could'nt be founded.

 

Any idea?

    Hi,

    You need to add the bound datafields to the columns collection. The example:

            WebDataGrid1.AutoGenerateColumns = false;
            BoundDataField boundFld1 = new BoundDataField(true);
            boundFld1.Key = "ID";
            boundFld1.Header.Text = "ID";
            boundFld1.DataFieldName = "ID";
            WebDataGrid1.Columns.Add(boundFld1);
            WebDataGrid1.Columns[“ID”].Hidden = true;

    I’ve attached a sample of this which also includes Paging.

    Please let me know if this resolves your issue.

    Thanks,
    Valerie
