Error:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
So, i really dont know how to overcome this....
If any one can help me Pls...............

It seems like view state of the controls put in CommandItemTemplate is not maintained. Also changing any of the properties in command event handler does not have any effect on the control. Here is the grid markup
| <telerik:RadGrid ID="NotesGrid" EnableEmbeddedSkins="False" Skin="srunite" Width="100%" |
| AllowSorting="False" AllowPaging="False" AllowMultiRowSelection="False" runat="server" |
| GridLines="None" EnableViewState="true"> |
| <MasterTableView Width="100%" Summary="RadGrid table" AutoGenerateColumns="False" |
| CommandItemDisplay="Top" TableLayout="Auto" GroupLoadMode="Client" AllowNaturalSort="false" |
| AllowSorting="false"> |
| <AlternatingItemStyle BackColor="#eeeeee" /> |
| <CommandItemTemplate> |
| <div class="gridActions"> |
| Notes |
| <asp:DropDownList ID="cmdFilterNoteType" runat="server" AutoPostBack="false" /> |
| <asp:LinkButton ID="cmdShowAll" runat="server" AutoPostBack="true" CommandName="ShowAll" |
| Text="Show All" Visible="false"/> |
| <asp:LinkButton ID="cmdShowLatest" runat="server" AutoPostBack="true" CommandName="ShowLatest" |
| Text="Show Latest" /> |
| </div> |
| </CommandItemTemplate> |
and here are event handlers
| protected void Page_Init(object sender, EventArgs e) |
| { |
| masterPage = (SiteMasterPages.BidModule)Master; |
| presenter.SetModel(masterPage.CurrentBid); |
| NotesGrid.ItemDataBound += new Telerik.Web.UI.GridItemEventHandler(NotesGrid_ItemDataBound); |
| NotesGrid.ItemCommand += new GridCommandEventHandler(NotesGrid_ItemCommand); |
| } |
First problem:
See how I am finding the LinkButton and making it invisible, or assigning different text but when it renders nothing has changed. I can see it finding the control, I can debug and see that property has been changed, but it still renders these controls as if nothing has changed. Why?
| protected void NotesGrid_ItemCommand(object source, GridCommandEventArgs e) |
| { |
| if (e.CommandName == "ShowLatest") |
| { |
| presenter.ShowLatestNotes(); |
| e.Item.FindControl("cmdShowLatest").Visible = false; |
| ((LinkButton)e.Item.FindControl("cmdShowLatest")).Text = "sdasdfdsaf"; |
| e.Item.FindControl("cmdShowAll").Visible = true; |
| } |
| else if (e.CommandName == "ShowAll") |
| { |
| presenter.ShowAllNotes(); |
| e.Item.FindControl("cmdShowAll").Visible = false; |
| e.Item.FindControl("cmdShowLatest").Visible = true; |
| } |
| } |
Second problem:
I have to rebind the dropdownlist that resides in commanditemtemplate on each postback as it does not maintain the viewstate. Why not?
| protected void NotesGrid_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) |
| { |
| if (e.Item.ItemType == GridItemType.CommandItem) |
| { |
| if (!Page.IsPostBack) |
| { |
| DropDownList filter = e.Item.FindControl("cmdFilterNoteType") as DropDownList; |
| if (filter != null) |
| { |
| filter.DataSource = _notes.Select(x => x.Key); |
| filter.DataBind(); |
| filter.Items.Insert(0, new ListItem("All")); |
| } |
| } |
| } |
| else if (e.Item.ItemType == GridItemType.GroupHeader) |
| { |
| GridTableCell cell = e.Item.Controls[0] as GridTableCell; |
| cell.Attributes.Add("noteType", ((System.Data.DataRowView)e.Item.DataItem).Row.ItemArray[0].ToString()); |
| } |
| } |

Hi, I have a hierarchical Grid with ShowGroupPanel set to true. Our specs require that when the users group by a column, both the grouping and the hierarchy for each row inside that group should be collapsed. I can accomplish the grouping part by setting the GroupsDefaultExpanded property to false, but when users expand each grouping, each underlying row will have its details expanded by default. HierarchyDefaultExpanded = False only seems to work when no grouping is taking place. Is there any way I can accomplish this without posting back to the server, either by setting a property to a specific value or through client-side code? Thank you.

Attempting to use the code:
item["fieldname"] inside of an OnItemDataBound handler for my RadGrid results in the exception:
'Telerik.Web.UI.GridNotSupportedException'
base {Telerik.Web.UI.GridException}: {"Item in insert mode does implement indexer only when the edit form is autogenerated"}'
Is there some other way to get to the data values in the OnItemDataBound, or some reasonable way to make this exception go away? My RadGrid is backed by a List of custom objects, which are mapped via telerik:GridBoundColumn. Autogenerating isn't an option, I need to use a form template for my client.
I tried searching the forums, but didn't find anything that explained this error.

How do I set the default value to checked when inplace editing a GridCheckboxColumn? Is this possible or would I have to use a template column with a checkbox set to checked? Also are there any examples of using a dropdownlistcolumn?
