Clear fields in grid item on item command

Hello

I have a grid with a template column like this

<telerik:GridTemplateColumn HeaderText="Program Id" AllowFiltering="true" Reorderable="true" SortExpression="Program_Id"

UniqueName="Program_Id" DataField="Program_Id">

<ItemTemplate>

<asp:Label ID="lblProgrammeId" runat="server" Text='<%# Eval("Program_Id") %>' />

</ItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="txbProgrammeId" Width="50px" runat="server" TextMode="SingleLine"

Text='<%# Bind("Program_Id") %>' />

<telerik:RadButton ID="ValidateProgBtn" AutoPostBack="true" runat="server" Width="16px"

Height="16px" CommandName="ValidateProgId" ToolTip="Validate the programme id" Text="Cancel">

<Image ImageUrl="Images/1305817624_clean.png" />

</telerik:RadButton>

<%--OnClientClicked="ClearFields" OnClientClicking="OnClientButtonClickingHandler"--%>

<telerik:RadButton ID="RadButton1" AutoPostBack="true" Value="NoPostBack" runat="server" Width="16px"

Height="16px" CommandName="Clear All"

ToolTip="Clear the fields" Text="Clear">

<Image ImageUrl="Images/1305817654_edit-clear.png" />

</telerik:RadButton>

<asp:Label ID="IsNewProgLbl" runat="server" style="width:auto; color:Orange" Text=""></asp:Label>

</EditItemTemplate>

<ItemStyle VerticalAlign="Top" />

</telerik:GridTemplateColumn>

When I click the clear all button, in edit mode, I want the fields from the grid to be cleared and also set the readonly property to false( it is set to true in a previous state). So I set the command name, then catch it in RadGrid1_ItemCommand event handler and try to access a field like this:

......

if (e.CommandName == "Clear All")

{

(e.Item.FindControl("txbProgrammeId") as RadTextBox).Text = "";

(e.Item.FindControl("txbProgrammeId") as RadTextBox).ReadOnly = false;

...........

But it seems that only the Label control exists! I can't find the RadTextBox or RadButton controls. I find this strange, since when the grid is in insert mode it works ok. I even tried to force the grid to be in edit mode

e.Item.Edit = true;

GridEditableItem editedItem = e.Item as GridEditableItem;

but still nothing.
Is there a way that I can use to solve this? Basically, I want a button that clears some fields when the grid is in edit or insert mode.

Thx a lot.

Using the same XML with RadMenu and RadTreeView

Hi,

Is it possible to use the same XML data source for both a RadMenu and a RadTreeView?

I am trying to convert an existing (non-Telerik) menu administration page over to use Telerik controls. The page displays the menu XML data as a tree view and allows the users to edit, add, and delete nodes. The XML content is in a database and is loaded using the LoadXML() method. Upon saving changes, the data is serialized back out using GetXML(), and the XML is written back to the database.

The reason I ask is because the XML formats for the two controls listed in the documentation are different:

RadMenu XML Format

<Menu Skin="Outlook">

<Item Text="Parent" LeftLogo="Img\parent.gif" >

<Group Width="140" Flow="Vertical">

<Item Text="Child 1" />

<Item IsSeparator="True" />

<Item Text="Child 2" />

</Group>

</Item>

</Menu>

RadTreeView XML Format

<Tree>

<Node Text="North America" Expanded="True" Value="1">

<Node>

</Node>

</Tree>

If it is not possible to load RadMenu XML data into a RadTreeView item directly, do you have any suggestions on how to achieve the same or similar effect?

Thanks,
Kevin

Radwindow inside radwindow

I'm trying to open a radwindow inside of another radwindow. It works fine in IE 7, but in firefox and IE 8, the window opens and starts to load, but it closes after a few seconds. My code is below.

function OnClientClose(oWnd, args) {

//get the transferred arguments

var arg = args.get_argument();

if (arg) {

var clientId = arg.ClientId;

var txtClientId = $find("<%= txtNewlclient.ClientID %>");

txtClientId.set_value(clientId.toString());

}

function showClientSearch() {

window.radopen("../../Sections/Clients/ClientSearch.aspx", "rwindClientSearch");

}

and my radwindow declaration

<telerik:RadWindowManager ID="rwindMgr" runat="server">

<Windows>

<telerik:RadWindow ID="rwindClientSearch" Title="Client Search" runat="server"

Width="350px" Height="300px" OnClientClose="OnClientClose" ReloadOnShow="true" ShowContentDuringLoad="false">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

This code works in other places when it's not inside of another radwindow.

FileExplorer & Absolute Paths

Hi,
I have recently started using the FileExplorer control for a file manager within our backend. Our system works with absolute paths (instead of relative), hence I implemented a custom FileBrowserContentProvider.

Everything works fine except for one single thing: when renaming a file from, for example, 'NewFileName.jpg' to 'File1.jpg', the file is renamed to 'NewFileName.jpgFile1.jpg' (the old file name and new file name are concatenated). This issue is only present withfile renaming. File move, directory move and directory rename all work fine. The parameter newPath in the MoveFile function within the content provider is already being supplied in a wrong manner (already concatenated). When I implemented the OnClientMove JavaScript function, the args.get_newPath(), however, was being shown as the proper new final.

I have no idea what else I can check for this to see what's going wrong. I attached my custom FileBrowserContentProvider hoping it may help.

Thanks,
Edward

RadWindow Standardization

Hello,

I'm trying to make sense of the RadWindow/RadWindowManager relation. I see that there can be many RadWindowManager controls defined in one page (unlike the RadScriptManager/ScriptManager which requires one implementation). But I also see that we can implement the RadWindow either inside of the RadWindowManager or as a standalone control.

What is the advantages of using the RadWindowManager beside being able to apply settings defined on the manager to the window? Is it better to keep the RadWindowManager outside of the master page and define it where it is needed, or is it better to keep a global radwindowmanager, and have radwindow as a standalone control?

Thanks.

custom filtering with objectdatasource in .NET 4.0

Hi,

I want to implement custom filtering in my radGrid, but I don't get it to work right now. What I'm trying to do is the following:

I have radGrid and the datasource of the grid is an objectdatasource. In the selecting event of the objectdatasource i add my filterexpression and sortexpression. In the function in my businesslogics, i have the filterexpression, sortexpression, startindex and maximumrows. The filterexpression is coming to the function properly, but i can't get it to work with my entitymodel. I've tried enableLinqExpression="True" and enableLinqExpression="False" but with both options it doesn't work.This is the code of the function:

public static IQueryable<vw_TrainingCompanyLocations> GetTrainingCompanyLocations(string filterExpression, string sortExpression, int maximumRows, int startRowIndex)

{

KolipeEntities db = new KolipeEntities();

IQueryable<vw_TrainingCompanyLocations> data;

if (!string.IsNullOrEmpty(filterExpression))

data = db.vw_TrainingCompanyLocations.Where(filterExpression);

else

data = db.vw_TrainingCompanyLocations;

return data;

}

Do you have any idea how to get this to work?

Displaying MsgBox On TOP of Modal RadWindow

I have a number of forms that open in a modal RadWindow. On the popup window, there are a number of other forms that can be edited individually. When they are saved, I wanted just a standard MsgBox to appear like so:

MsgBox("Information has been updated. ", MsgBoxStyle.Information, "Information Update")

That works fine, however it does NOT open over the top (or take focus) over the RadWindow.

Also, once the user clicks ok on the msgbox, how can I also close the RadWindow?

Rad Editor absolute positioned sub windoes issue

I have a issue where I have the rad editor absolute positioned. When the editors sub windows popup (ex: Hyperlink manager) they are appearing behind the editor. If I drop the z_index down to a low number then they work fine, but that for me would cause a issue. I want to give the editor a higher z-index to make sure of no issues, since other objects can also be absolute positioned on the page and their is a risk of the number becoming higher than the editor z-index. Is there a way to change the sub windows z-index from code or javascript or even a css file to have higher z-indexes?

The same page worked great for years using the 6.5 version of the editor and I never ran into this problem with that editor. However IE 9 doesn't play nice with that version.

Mimic RadGrid filtering

Hello, I'm trying to mimic RadGrid filtering. I would like to have e.g. 3 textboxes with filter button which would work exactly with the same way like RadGrid filtering. The same subset of filtering options and the same filterexpression generated. Could you advice me what is the best way to do so? I would not like to write such functionality from scratch.

Kind Regards
Marcin
