Hi,

I have requirement where on 1 main aspx page i have 3 user controls(ascx).

Each ascx has a radgrid.I need to save state of each grid in database individually on gridbutton click.

Tried- I have created a custom storage provider and implemented methods SaveStateToStorage and LoadStateFromStorage.

Now if I apply persistencemanger on any ascx and call .savestate it goes to SaveStateToStorage and all works fine.

But if I move persistencemanger to aspx and apply persistencemangerproxy on ascx nothing works.

Sample code-

on aspx- <telerik:RadPersistenceManager ID="mainPersistenceManager" runat="server"> </telerik:RadPersistenceManager>

on aspx.vb- pageload event - mainPersistenceManager.StorageProvider = New SettingsStorageProvider() 'This is my custom storage provider

on ascx- <telerik:RadPersistenceManagerProxy ID="PersistenceManagerProxy1" runat="server" UniqueKey ="1">

on ascx.vb- on button click event-

Dim ascxPersistenceManager As RadPersistenceManager

ascxPersistenceManager = RadPersistenceManager.GetCurrent(Page)
ascxPersistenceManager.PersistenceSettings.AddSetting("radgrid1")
SettingsStorageProvider.StorageProviderKey = Key
ascxPersistenceManager .SaveState()

Now on button click i get exception that it could not find control with id=radgrid1

but if i comment this line "ascxPersistenceManager.PersistenceSettings.AddSetting("radgrid1")"

somehow it calls "LoadStateFromStorage" of my custom storage provider rather than "SaveStateToStorage" method.

Incase when i dont use proxy and put persistencemanger in ascx only it hits correct method but not in case of proxy.

Please help

Thanks,

Ankita

Preserve filtered radgrid on Back button click

I have a radgrid with filtering enabled. Clicking an item in the grid does a Response.Redirect to another page to open the item details page. When I click browser's Back button, the grid is displayed with all the filtering cleared. Is there a way to preserve filtering?

Editing in a hierarchical grid

I have a hierarchical parent-child grid where only the child rows can be edited.

When any parent row is expanded I need to have the child rows immediately placed in edit mode. They also need to retain their values for posting if the parent row is subsequently collapsed, so that all child rows can be enumerated for posting the results. How would I accomplish that?

Following is the markup for the grid

column visible=false works, true does not?

I have a combobox with checkboxes to choose what columns in a grid to have visible and not, the grid and combobox is ajaxified.

on the combobox itemChecked event i find the appropiate column and set its visibility value based on the checkbox, all very simple enough,

protected void cmbGridColumnChooser_ItemChecked(object sender, RadComboBoxItemEventArgs e)

{

grCases.Columns.FindByUniqueName(e.Item.Value).Visible = e.Item.Checked;

var test = grCases.Columns.FindByUniqueName(e.Item.Value).Visible;

}

However, setting the column to visible=false works great But when setting the column visible to visible=true again does not, even though the checkbox state shows true, and after checking the columns visible state straight afterwords (its true) the column still wont appear.

Any ideas anyone?

Change count of selected items

Hi,

I have a RadComboBox which has an extra "Select All"-type item to select a sub set of all items. When this item is checked and the combobox is closed, I would like for the counter to ignore it when displaying how many items are checked.

e.g. The combobox contains "Select all", "Select all fruits", "apple", "banana", "monkey"

If I check "banana" and "monkey", it displays "2 items checked".

If I check "select all fruits", "apple" and "banana" will be checked but since "select all fruits" is also an item, it will display "3 items checked"

I haven't been able to find a way to have the combobox ignore one of the listitems or to change the count of selected items. Is this possible?

DockCommand as a RadAjaxManager trigger

Hi,

I'm using in a web application RadDock control. However I'm trying to figure out if it is possible to use DockCommand as a RadAjaxManager trigger. Because DockCommand has no ID it seems very hard to achieve this.

My application scenario is quite easy to understand. The dock command button must load a user control in a panel (ExtendedViewPanel) and then reload it. Please consider the following code :

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="MyDockCommand">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="ExtendedViewPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadDockLayout runat="server" ID="RadDockLayout1">

<table style="width:100%">

<tr>

<td>

<telerik:RadDockZone runat="server" ID="RadDockZone1" Orientation="Horizontal" Style="border: 0;">

<telerik:RadDock RenderMode="Lightweight" ID="RadDock1" runat="server" Title="Classeurs non publiés"

EnableAnimation="true" CssClass="higherZIndex" Width="33%" Skin="Metro" OnCommand="RadDock1_Command">

<Commands>

<telerik:DockToggleCommand Name="SwitchView" AutoPostBack="true" CssClass="command-maximize"/>

</Commands>

<ContentTemplate>

<div>

<widget:LastModifiedWorkbook ID="LastModifiedWorkbookControl" runat="server" />

<asp:HiddenField runat="server" ID="toggleState" />

</div>

</ContentTemplate>

</telerik:RadDock>

</telerik:RadDockZone>

</td>

</tr>

</table>

</telerik:RadDockLayout>

<asp:Panel runat="server" ID="ExtendedViewPanel" CssClass="extended-view-panel" Visible="false">

</asp:Panel>

Thanks for your help,

Dock

Filtering/Sorting

So I have a grid that is pulling most of it's information from one context/one database (db1). But I have one column that is pulling it's information from another context/database (db2) based on one of the columns from db1. However, if I try to filter or sort on this column, nothing happens. I have exhausted my researching abilities and tried many fixes for this and none of them are working great. What, in your opinion, would be the best solve?
