Hello,
        I am using RadControls for ASPNET AJAX Q1 2009. 
I am having a RadGrid with filters on different fields. For all filters I am using RadComboBox.
I have referes to the method given for FilterTemplates example for using RadComboBox as filters.
One of the RadGrid column is displaying the Date of record.
But I have to filter this date according to Year only. 
For Ex: If I have 10 dates of year 2005 and 3 dates of 2006. Then the filter combo for date should contain items as 2005 and 2006.
         Hence whenever I select 2005 from filter it should display all dates from year 2005 along with other filters if applicable.

But now I am unable to show the year in RadComboBox filter. Also I am not able to filter on Year.

Please help me regarding this if anyone finds any solution. This is very urgent.

Thanks,
Pinkey

Hi

This is what I want to acomplish.

1. when i click b1 (postback p1) only p1 to update

2. when i click b2 (postback p2) only p2 and p3 to update

here is the code and why it's not working correct?

Hello Telerik,

The environment:
- I created a form with a RadGrid with 3 levels
- The third level (the question) has a user control that has a RadioButtonList
- The second level (the sub-section) has a RadioButtonList that looks like the other one, to change the value of all the radios in this sub-section
- The first level (the section) just shows the titles
- Screen shot: Here
- The form used has 53 controls, each one of them has a RadioButtonList with 6 options, a RadTextBox and a HiddenField. They are divided in 18 sections, and the header of those sections has also a RadioButtonList with 6 options each. That's a total of 71 RadioBoxLists and 426 radios.

Now, the problem:
- When clicking in any radio in the third level, the CPU of the client goes to 100% for around 1 second. With a slower computer, it goes up to 3 seconds.
- When clicking the radio in the sub-section, it takes a real long time to change the indexes from the inside radios. In a good client computer, around 10 seconds, and up to 30 seconds in a slower one. The following JavaScript function is used:
- It is much faster when using Firefox than Internet Explorer, but Firefox is still really slow.

Finally, the questions:
- Is it possible to improve the performance, or should I just forget using the form decorator?
- The decorator is in my master page. Is it possible to turn it off for a single section?

Thank you very much,
Daniel Schiavini

Hello,

I have read a few threads in this regards but have not yet got my code working for cascading radcombo in edit mode in radgrid!

Here is my code in aspx page:

 

<telerik:RadGrid ID="gv_Users" runat="server" AutoGenerateColumns="False" GridLines="None" Height="100%" Width="100%" AllowPaging="True" AllowSorting="True" PageSize="15" OnNeedDataSource="gv_Users_NeedDataSource" OnItemCreated="gv_Users_ItemCreated" OnItemDataBound="gv_Users_ItemDataBound">

 

 

<MasterTableView DataKeyNames="UserID,ConID,RoleID,Container_Name,Role_Name">

 

 

<ExpandCollapseColumn Visible="False">

 

 

<HeaderStyle Width="19px" />

 

 

</ExpandCollapseColumn>

 

 

<RowIndicatorColumn Visible="False">

 

 

<HeaderStyle Width="20px" />

 

 

</RowIndicatorColumn>

 

 

<Columns>

 

 

<telerik:GridTemplateColumn UniqueName="col_Edit">

 

 

<HeaderStyle Width="50px" />

 

 

<ItemTemplate>

 

 

<span style="white-space: nowrap;">

 

 

<asp:ImageButton ID="btnEdit" runat="server" meta:resourceKey="btnRole_Edit" CommandName="edit" ToolTip="Edit" SkinID="ImgBtnEdit" />

 

 

<asp:ImageButton ID="btnDelete" runat="server" meta:resourceKey="btnRole_Delete" CommandName="remove" ToolTip="Delete" SkinID="ImgBtnDelete" OnClientClick="return confirm_action('Continue with delete? \nContinuer avec la suppression?');" Visible="false" /></span>

 

 

</ItemTemplate>

 

 

<ItemStyle Width="50px" />

 

 

</telerik:GridTemplateColumn>

 

 

<telerik:GridDropDownColumn UniqueName="ddContainerEdit" ListTextField="Container_Name" ListValueField="Container_Name" DataField="Container_Name" HeaderText="Container_Name" DropDownControlType="RadComboBox" />

 

 

<telerik:GridDropDownColumn UniqueName="ddRoleEdit" ListTextField="Role_Name" ListValueField="Role_Name" DataField="Role_Name" HeaderText="Role_Name" DropDownControlType="RadComboBox" />

 

 

<telerik:GridBoundColumn DataField="UserID" DataType="System.Guid" HeaderText="UserID" UniqueName="col_UserID" meta:resourceKey="col_UserID" SortExpression="UserID" Visible="False">
.......

And here is my code behind page code:

 

 

Protected Sub gv_Users_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles gv_Users.ItemCreated

 

 

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then

 

 

 

 

 

'the combobox will be the first control in the Controls collection of the corresponding cell

 

 

 

 

 

 

 

 

Dim list As RadComboBox= CType(CType(e.Item, GridEditableItem)("ddContainerEdit").Controls(0), RadComboBox)

 

 

'attach SelectedIndexChanged event for the combobox control

 

 

 

 

list.AutoPostBack =

True

 

 

 

 

 

AddHandler list.SelectedIndexChanged, AddressOf Me.ddContainerEdit_SelectedIndexChanged

 

 

End If

 

 

 

 

 

End Sub

 

 

 

 
My error message:
Unable to cast object of type 'System.Web.UI.WebControls.Literal' to type 'Telerik.Web.UI.RadComboBox'.
I have tried changing the index in Controls(0) from 0 to 3 but it still gives me the same above error.

When I try index 4, My error message:
Specified argument was out of the range of valid values. Parameter name: index

Can you help?

Thanks,
Sanjay

I need a little direction here. 

I open a RadWindow from my main page.  Inside the RadWindow I have a button called "Upload".  When clicked, I want to open a second RadWindow.  However, I'm stuck right now because what should open as a second RadWindow is actually replacing the content of the first RadWindow.

How can I solve this problem?  Comments would be appreciated!

I have 5 RadGrids on a page, registered with RadAjaxManager (AddAjaxSetting(grid, grid, loadingpanel)).

All grids use paging and hook the NeedDataSource() event. 

When I page through one grid, there is no full page refresh, the loading panel appears as expected and paging functions correctly. 

However, when I investigated the very slow paging I discovered that NeedDataSource (and infact all the lifecycle events) was firing on all 5 grids and not just the one that I was actually paging.

Is there any way that the RadAjaxManager could be refreshing all it's AjaxSettings regardless of which control is the trigger?

Thanks,

Hey,

I am having a problem with a RadDatePicker.  My picker is sitting inside a GridTemplateColumn under the EditItem section.  I am wanting to set the SelectedDate and the MaxDateRange from the codebehind but I cannot figure out how to access the control.  Can you please help me out??


Thanks,

Kyle

Hi all,
I have installed for Insert Command with code in ItemCommand event:
if (e.CommandName == RadGrid.InitInsertCommandName)
            {
                e.Canceled = true;
                e.Item.OwnerTableView.InsertItem();
                e.Item.OwnerTableView.IsItemInserted = true;
                GridEditableItem insertedItem = e.Item.OwnerTableView.GetInsertItem();
                String MyUserControlId = GridEditFormItem.EditFormUserControlID;
                UserControl userControl = insertedItem.FindControl(MyUserControlId) as UserControl;               
            }
this run well.

However, I don't know how to find my usercontrol when click Edit command. Please help me!

Thanks!
