Questions on UI for ASP.NET AJAX Forum

Hello,

I have a small question, about the SortExpression in a GridTemplateColumn.
In fact, I have a SQL table [Action] and a table [PlanActionNiveauDeRealisation]. Like this an [Action] can have a lot of [PlanActionNiveauDeRealisation].

So, I put a RadGrid with all my [Actions] and in the last columns I put this :

<telerik:GridTemplateColumn UniqueName="LastNiveau" HeaderText="Niveau de réalisation" >

<ItemTemplate>

<telerik:RadRating ID="ratingBar" runat="server" Orientation="Horizontal" ItemHeight="61px"

ItemWidth="11px" CssClass="ratingClass" OnRate="ratingBar_Rate" AutoPostBack="true">

<Items>

<telerik:RadRatingItem Value="0" HoveredImageUrl="/images/Rating/Rating1/2h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/2h.png"

SelectedImageUrl="/images/Rating/Rating1/2s.png" ImageUrl="/images/Rating/Rating1/2.png" ToolTip="0 %" />

<telerik:RadRatingItem Value="25" HoveredImageUrl="/images/Rating/Rating1/3h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/3h.png"

SelectedImageUrl="/images/Rating/Rating1/3s.png" ImageUrl="/images/Rating/Rating1/3.png" ToolTip="25 %" />

<telerik:RadRatingItem Value="50" HoveredImageUrl="/images/Rating/Rating1/4h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/4h.png"

SelectedImageUrl="/images/Rating/Rating1/4s.png" ImageUrl="/images/Rating/Rating1/4.png" ToolTip="50 %" />

<telerik:RadRatingItem Value="75" HoveredImageUrl="/images/Rating/Rating1/5h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/5h.png"

SelectedImageUrl="/images/Rating/Rating1/5s.png" ImageUrl="/images/Rating/Rating1/5.png" ToolTip="75 %" />

<telerik:RadRatingItem Value="100" HoveredImageUrl="/images/Rating/Rating1/6h.png" HoveredSelectedImageUrl="/images/Rating/Rating1/6h.png"

SelectedImageUrl="/images/Rating/Rating1/6s.png" ImageUrl="/images/Rating/Rating1/6.png" ToolTip="100 %" />

</Items>

</telerik:RadRating>

</ItemTemplate>

</telerik:GridTemplateColumn>

In the ItemDataBound, I put :

protected void RGPlanAction_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)

{

var maxLength = 50;

var dataItem = e.Item as GridDataItem;

var myPlanAction = (Model.PlanAction)e.Item.DataItem;

var myRadRating = (RadRating) dataItem["LastNiveau"].FindControl("ratingBar");

myRadRating.Attributes.Add("IdPlanAction", myPlanAction.IdPlanAction.ToString());

myRadRating.Attributes.Add("IndexRadGrid", e.Item.ItemIndex.ToString());

var ndr = myPlanAction.PlanActionNiveauDeRealisation.LastOrDefault();

if(ndr != null)

{

myRadRating.Value = ndr.NiveauDeRealisation;

}

else

{

myRadRating.Value = 0;

}

Like this, it's perfect, I have a nice RadGrid with the last [PlanActionNiveauDeRealisation] of each [action].

Just, I would like to make some sorting with this last column : [lastNiveau], but i dunno what to put in the SortExpression...

Do you have any idea?

Thank you

Grid

RadComboBox in User Control: Deleting Text Doesn't Fire Text Changed Postback

Hi,

I am using version 2009.2.826.35 and I am unable to update to the latest version at the moment. There is a bug in this version when the RadComboBox gets placed in a user control and it is set for Load On Demand. Even though the RadComboBox has the AutoPostback set to true, the postback does NOT occur when the user highlights the text in the RadComboBox and clicks delete or backspace.

I have access to a later dll (2010.1.519.35) and I verified that this bug was fixed in this version. However, as I mentioned before, at the moment we don't want to update to the latest dll. Are there any other work arounds that can fix this bug?

Here is a link to a demo project that shows the bug (link expires on Jan 16 2011): Sample Project
Thanks,
Oran

RadListBox not showing items when used with RadGrid

Hi, I have a simple page with RadGrid above two RadListBox controls that are supposed to be populated with different items based on which item is selected in the grid.

No matter what techniques I try, RadListBox controls appear to be empty on the page. I am currently trying to use simple method shown here:

http://www.telerik.com/help/aspnet-ajax/listbox-working-with-items-server-side.html

Basically manually adding an object of type RadListBoxItem directly to the RadListBox in question, but the box remains empty on the page, any tips? Maybe grid is throwing it off in some way? How do I refresh it?

Telerik have anything like Dart's LiveControls for ASP.NET?

Hello,

Does Telerik have anything like Dart's LiveControls for ASP.NET (http://www.dart.com/pwlc_overview.aspx)? I'm new to Telerik and am currently working on a big project which will require a good deal of client to server interaction. Looks like the best solution other than potentially LiveControls is to write JavaScript in order to avoid postback caused screen flickering. Any suggestions for this issue or getting to know Telerik?

Thanks

Geoffrey

Issues with DetailTable Admin form

Hi All,

I've been trying to figure this out for a while and not having much luck hence this posting.

I have a grid that has a subgrid for each row using detailtables, both levels are editable. Because I have checkboxes in the admin form of each level I need to setup the value of any new rows in the InitInsert event and all of this works nicely.

I have two issues now. The fist issue is that I need to conditionally hide the checkbox (and potentially other fields) in the child level depending on a value in the parent level. The second issue is that I want to have a checkbox present on the form which when ticked and the record is saved a new insert form opens up - thus saving the user from clicking a on the new item icon again.

Re the first issue I have the following in the ItemCommand event for the grid,

...

ElseIf e.CommandName = "InitInsertElement" Then

e.Canceled = True

Dim newValues As System.Collections.Specialized.ListDictionary = New System.Collections.Specialized.ListDictionary()

newValues("IncludeInTotal") = True

'IF THE CostType CELL IN THE PARENT ROW = UnitCost THEN HIDE THE uxIncludeInTotal CHECKBOX ON THIS INSERT FORM

DirectCast(e.Item, Telerik.Web.UI.GridDataItem).ChildItem.NestedTableViews(0).InsertItem(newValues)

ElseIf .....

Re the second issue I have tried the following code to trigger the insert form to reopen but although the itemcommand is triggered the insert form does not load.

If CType(editedItem.FindControl("uxAddNewAfterSave"), CheckBox).Checked Then

Dim parentItem = CType(e.Item.OwnerTableView.ParentItem, Telerik.Web.UI.GridDataItem)

parentItem.FireCommandEvent("InitInsertElement", String.Empty)

End If

Any help please?

Regards,

Jon

Change color of button on hover

Hi

I am trying to modify slightly the color of the button on hover when using the form decorator with 'Hay' skin.
Tried a css file technique (see below) that worked with an earlier version of the controls, but it doesn't work now (Q2 2010 release).
Can you tell me what I should be using instead?
Thanks
Clive

a.RadForm_Hay:hover .rfdInner {color: #ACB936 !important;}

Grid Column rename/remove

Hi,

I want your help to the following problem.

I have a grid which calls an OnNeedDataSource event to fetch data. The grid columns and data are automatically created based on the list(Of Object) I pass to the grid datasource. The problem I have is that I want to REMOVE and RENAME some columns from the grid but I want to maintain the way the grid works now. How can I rename the column headers of the grid or make them visible false from code behind? From the aspx file I can't do anything because in the ...<MasterTableView><Columns>... tag I don't include any data.

Thanks
George
