I am having a problem inserting records on a Sub heirarchial grid. If no dta exists it errors our the bind function for the editing. But if existing data is loaded for that sub grid the insert works just fine. So on insert of the datatable has nothing in it it will error out on the 1st textbox that is bound to data from datatable and give the follwoing error. But the problem is the field is there becuase it works for other rows with data. If you manually insert record, it will work fine. What is the work around to this.

DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'strDescription'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

HI,

Ok I tried to correct it with the link that you sent but still a no go. Here is the code I implimented. But it still gets the same error there is no strDescription, but only when no record exists at that level. If one exists it works just fine.

if (e.CommandName == RadGrid.InitInsertCommandName && e.Item.OwnerTableView.Name == "Positions")

{

System.Collections.Specialized.ListDictionary newValues = new

System.Collections.Specialized.ListDictionary();

newValues["strDescription"] = string.Empty;

newValues["strScale"] = string.Empty;

newValues["strPositionType"] = string.Empty;

newValues["strGrade"] = string.Empty;

e.Item.OwnerTableView.InsertItem(newValues);

}

This is the section of the Grid

<Columns>

<telerik:GridEditCommandColumn ButtonType="LinkButton" EditText="Edit" />

<telerik:GridBoundColumn DataField="strDescription" HeaderText="POSITION DESCRP" />

<telerik:GridBoundColumn DataField="gsScale" HeaderText="GS-SCALE" />
