I have a grid with a master and detail table. The master table has several rows. When I click a row to expand the detail table, in the ItemDataBound Event I have some code that populates a dropdown in the detail table, as below
The contents of the drop down are determined by 2 values, a 'type' which is a drop down on the main page, and 'genre' which is a column in the master table in the grid. After searching the forums, the only method I could find to obtain this value from the master table is by using a hashtable, like so
After stepping through the code, the hash table is always empty (its count is zero), yet the master table has data. How Can I obtain the data I need from the selected row in the master table ?? Is there another way ?
if ("ArtistCategories".Equals(e.Item.OwnerTableView.Name)) |
{ |
if (e.Item is GridEditableItem && e.Item.IsInEditMode) |
{ |
GridDataItem dataitem = e.Item.OwnerTableView.ParentItem; |
Hashtable values = new Hashtable(); |
dataitem.ExtractValues(values); |
object Objgenre = values["Genre"]; |
GridEditableItem _item = (GridEditableItem)e.Item; |
Telerik.Web.UI.RadComboBox cb = (Telerik.Web.UI.RadComboBox)_item["ArtistCategory"].FindControl("RadComboBoxCategories"); |
string genre = Objgenre.ToString(); |
cb.DataSource = lookupmanager.CategoryByGenre(genre, this.RadComboBoxType.SelectedValue); |
cb.DataTextField = "Category"; |
cb.DataValueField = "Category"; |
cb.DataBind(); |
try |
{ |
Studio1DBObjects.SecondaryCategory sg = (Studio1DBObjects.SecondaryCategory)e.Item.DataItem; |
string category = sg.Category; |
int index = cb.FindItemIndexByValue(category); |
cb.SelectedIndex = index; |
} |
catch (Exception ex) |
{ |
// |
} |
} |
} |
