Binding one column from DataView DataTable to WebDropDown
posted

Hello,

I'm using dropDownProvider in whdg. I want to bind ddp to datasource, which is dataview (to be exact, to one of the columns of DataTable from DataSource). For ultrawebgrid it could be done like this 

UltraWebGrid1.Columns[2].Type = ColumnType.DropDownList;
UltraWebGrid1.Columns[2].ValueList.DataSource = dv;
UltraWebGrid1.Columns[2].ValueList.DisplayMember = "Name";
UltraWebGrid1.Columns[2].ValueList.ValueMember = "Name";
UltraWebGrid1.Columns[2].ValueList.DataBind();

I tried this 

this.DropDownProvider1.EditorControl.DataSource = dv;
this.DropDownProvider1.EditorControl.DataMember = "Name";
this.DropDownProvider1.EditorControl.DataBind();

But it throws "System.InvalidOperationException" exception on DataBind(). I also tried ValueField instead of DataMember, but then it displays empty strings

    Hi Andrey,

    I would suggest you to get the editor and set data source like this:

    WebDropDown editor = (WebDropDown)WebHierarchicalDataGrid1.EditorProviders["DropDownProvider1"].GetEditor();
    editor.DataSource = dv;
    editor.DataMember = "Name";

    Let me know if this helps.
