Hierarchy Grid detail table DataSource

[RJ]

I have a list of objects that are used as a datasource for the detail table. Not all the fields from the datasource are in the detail grid. I am using the edit form template. Is there any way I can access the detail table datasource fields (not in the detail grid) in the updatecommand event.

Thanks

Hi RJ,

If you need to get the values for the edit form you can use the ExtractValuesFromItem method of the OwnerTableView. You can find further information in this help article in the section Example1: Using ExtractValuesFromItem.

Hi Marin,

The ExtractValuesFromItem method provides information if the fields are  bound to the grid. However,the list DataSource has additional fields that are not part of the grid. How can I get the additional fields from the DataSource which are not part of the grid.

Thank you

Hi RJ,

You can access the actual object to which the grid item is bound by using the DataItem property which will return your custom data object and then you can access its fields. Note that in order the DataItem property to be initilized you need to Rebind the grid first. Here is a sample code snippet:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
    {
        RadGrid1.Rebind();
        CustomObject obj = e.Item.OwnerTableView.Items[e.Item.ItemIndex].DataItem as CustomObject;
        //you can access obj.Field1, obj.Field2, etc.
    }

Additionally you can get access to the whole collection using the DataSource property of the grid, assuming it has been set in the NeedDataSource event in order to bind the grid.

List<CustomObject> customCollection = RadGrid1.DataSource as List<CustomObject>;
        // access properties of collection

Hope this helps.

Hi Marin,

I need the datasource for the detail table and it is set in the detail table data bind event. How can I get access to the DataSource property of the detail table in the update command event.

Thank you.

Hi RJ,

 You can get access to the DataSource property of the detail table in the following way:

protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
        {
            //you need this check in case you have more that one levels of hierarchy and you have set the Name of the DetailTable so that they can be distinguished
            if (e.Item.OwnerTableView.Name == "Orders")
            {
                e.Item.OwnerTableView.Rebind();
                DataSet ds = e.Item.OwnerTableView.DataSource as DataSet;

             }

            }
        }
