When a user begins an edit operation, we set the appropriate content by calling set_Html on the client. However, this action appears in the Undo dropdown. Is there a way to clear the Undo stack, or prevent the set_Html call from adding to the Undo stack?

Ajax request

I have a master page with an AJAXManager on it, then in a contents page I have a RadManagerProxy

                    <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">         
                <AjaxSettings>         
                    <telerik:AjaxSetting AjaxControlID="RadGridSecondaryCategories">         
                        <UpdatedControls>         
                            <telerik:AjaxUpdatedControl ControlID="RadGridSecondaryCategories"          
                                LoadingPanelID="RadAjaxLoadingPanel1" />         
                        </UpdatedControls>         
                    </telerik:AjaxSetting>         
                </AjaxSettings>         
            </telerik:RadAjaxManagerProxy>         

I then have some javascript that initiates an ajax request, but when I load the page I get this compiler error

                    Compiler Error Message: CS0104: 'RadAjaxManager' is an ambiguous reference between 'Telerik.WebControls.RadAjaxManager' and 'Telerik.Web.UI.RadAjaxManager'         
                     
            Source Error:         
                     
                      
                     
            Line 107:                         
            Line 108:                if (!arg) {         
            Line 109:                    $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("SubCategoryRebind");         
            Line 110:                }         
            Line 111:                else {         

Both the RADManager and RadProxy are asp.net AJAX versions, so why am I getting this error ?

RadTreeView - FormDecorator

I have a page containing a copy the following demo;

http://demos.telerik.com/ASPNET/Prometheus/TreeView/Examples/Functionality/CheckBoxes/DefaultCS.aspx

This works fine, only after adding the formdecorator control to my form the CheckChildNodes property stays unchanged after postback.

Are those controls not compatible or is there a way to fix this?

Client Event for Item Focus

Is there a client event that gets fired when an item gets focus or when the row changes? I'm not referring to events tied to mouse clicks but rather to keyboard use (e.g., tabbing from textbox to textbox). I want to update a label on the webpage as the cursor moves from field to field.

RadDatePicker Client-Side Issue and Invalid Date Format

Hello,

I have an ASP.NET application written in C# in which I have a RadDatePicker object on the form. When the user selects a particular menu option the resulting function should get the date from the DatePicker, and pass that date in the URL to the next screen, which is invoked using the RadWindow component.

The problem is that the date being passed contains the following:

"Fri Oct 17 00:00:00 EDT 2008"

This cannot be converted to a DateTime object correctly.

The code within my RadCodeBlock is as follows:

<telerik:RadCodeBlock ID="cb1" runat="server">

function DisplayStatistics() {

var picker = $find("<%= RadDatePicker1.ClientID %>");

var selectedDate = picker.get_selectedDate();

var oManager = GetRadWindowManager();

var oWnd = oManager.open("./TradeBlotterStats.aspx?ID=" + selectedDate, "rwBlotterStatistics");

}

</script>

</telerik:RadCodeBlock>

Thanks in advance for any help you can provide,

David Nowak.

RadWindow not poping up.

Hi All,

I just have an issue with the RadWindow not opening ffrom a linkbutton inside a datagrid, here is the HTML:

<

radG:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" EnableAJAX="True" GridLines="None" Skin="Blue">

<radG:GridTemplateColumn UniqueName="TemplateColumn">

<asp:LinkButton ID="btnViewCard" runat="server" OnClick="OpenCard">Show Card</asp:LinkButton>

</ItemTemplate>

</radG:GridTemplateColumn>

<radG:GridBoundColumn DataField="CardID" Display="False" HeaderText="CardID"

ReadOnly="True" UniqueName="CardID">

</radG:GridBoundColumn>

<radG:GridBoundColumn DataField="Sender" HeaderText="Sender" UniqueName="Sender" ReadOnly="True">

</radG:GridBoundColumn>

<radG:GridBoundColumn DataField="SenderPhone" HeaderText="Sender Phone" UniqueName="SenderPhone">

</radG:GridBoundColumn>

<radG:GridBoundColumn DataField="SenderEmail" HeaderText="Sender Email" UniqueName="SenderEmail">

</radG:GridBoundColumn>

<radG:GridBoundColumn DataField="PatientName" HeaderText="Patient Name" UniqueName="PatientName">

</radG:GridBoundColumn>

<radG:GridBoundColumn DataField="PatientRoom" HeaderText="Patient Room" UniqueName="PatientRoom">

</radG:GridBoundColumn>

<radG:GridBoundColumn DataField="imgURL" HeaderText="imgURL" UniqueName="imgURL" Display="False">

</radG:GridBoundColumn>

</Columns>

</RowIndicatorColumn>

</ExpandCollapseColumn>

</MasterTableView>

</radG:RadGrid>

And here is the vb.net:
Protected Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.WebControls.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

Dim getDS As New DataSet

getDS = dataConn.GetAllNewCards()

RadGrid1.DataSource = getDS.Tables(0).DefaultView

End Sub

Public Sub OpenCard(ByVal sender As Object, ByVal e As System.EventArgs)

RadWindow1.VisibleOnPageLoad =

True

RadWindow1.NavigateUrl = "CardEditor.aspx"

End Sub

What am I doing wrong,

Thank,
Shehab

But Iam not able to see the CommandItemTemplate on the child table grids..
Only the one set during design tiimje for mastertableview is visisble.

Below is the code with jsut the Delete Command

private

class ProductCommandItemTemplate : ITemplate

public ProductCommandItemTemplate()

{

deleteButton =

new LinkButton();

}

public void InstantiateIn(Control container)

{

deleteButton =

new LinkButton();

deleteButton.ID =

"deleteButton";

deleteButton.Text =

"Delete record";

deleteButton.CommandName =

"InitDelete";

container.Controls.Add(deleteButton);

}

private

void CreateHierarchyTableTemplates(int noOfLevels)

{

GridTableView parentTableView = radGridProducts.MasterTableView;

parentTableView.DetailTables.Clear();

for (int i = 0; i < noOfLevels; i++)

{

GridTableView newParentTableView = CreateProductChildGrid(parentTableView);

parentTableView = newParentTableView;

}

private GridTableView CreateProductChildGrid(GridTableView parentGridTableView)

{

GridTableView tableViewChildProduct = new GridTableView(radGridProducts);

parentGridTableView.DetailTables.Add(tableViewChildProduct);

tableViewChildProduct.DataSource =

new List<InstrProduct>();

AddProductChildGridAttributes(tableViewChildProduct);

tableViewChildProduct.EnableColumnsViewState =

true;

return tableViewChildProduct;

}

private void AddProductChildGridAttributes(GridTableView tableViewChildProduct)

{

GridBoundColumn col5 = new GridBoundColumn();

tableViewChildProduct.Columns.Add(col5);

col5.DataField =

"LongDescription";

col5.UniqueName = tableViewChildProduct.Name +

"_colLongDescription";

col5.HeaderText =

"Long Description";

GridHyperLinkColumn col6 = new GridHyperLinkColumn();

tableViewChildProduct.Columns.Add(col6);

"_colCharacteristics2";

col6.HeaderText =

"Characteristics";

col6.DataNavigateUrlFormatString =

"javascript:ShowEditForm('{0}');";

col6.DataNavigateUrlFields =

new string[] { "Id" };

col6.Text =

"View";

}

protected

void Page_Load(object sender, EventArgs e)

{

if (!this.IsPostBack)

{

int noOfproductLevels = _presenter.GetNoOfProductLevels();

radGridProducts.MasterTableView.Width =

Unit.Percentage(100);

radGridProducts.MasterTableView.DataKeyNames =

new String[] { "Tag", "ParentTag", "Id" };

CreateHierarchyTableTemplates(noOfproductLevels);

}

}

We just create the child tables dynamically

Catching upload error on client side

Hi,

How can I trap/catch an unknown upload failure on client side and display custom error message/feedback to the user?

I'm using RadUpload And RadProgressArea controls. I display progress bars.
I don't have exact error details, but I remember when an upload failed, a huge javascript alert box was displayed with all technical jargons.
I want to catch that and display custom/user-friendly error message to user.

We can assume we are talking about timeout. I know I can set the maxrequestlength and session time limit in web config.

Thanks,
Chirag
