RadDatePicker not loading inside RadGrid of type Several Tables Level

Hi,

I am facing this unusual bug, I have a form in a RadGrid, at fourth level i have a RadDatePicker control which allows users to select the date and save the data.

Problem:
Sometimes the RadDatePicker is loading as a normal TextBox control and the image button which popups the calendar control is dissappearing. After several refresh, it loads normally. What is wrong in this control?

Please help.

row value roundup problem

hi, all
i am using RadGrid in my application , i am binding the grid with database values and my db table contains some real data type field
for those values (real data type field) radgrid displaying wrong
for example :- in my table value is 13.4
my radgrid is showing this value like 13.3987654321

even i used data-format string expression then also it is displaying wrong value
it's not rounding up that value.
i used following expression
{0:####0.###}
{0:F3}%
{0:000.0}

and the code is below
<telerik:GridBoundColumn DataField="MinimumQuantityForOrdering" HeaderText="Min. Order Qty "
                                        UniqueName="MinimumQuantityForOrdering" DataFormatString ="{0:F3}%"
                                        AutoPostBackOnFilter="true" CurrentFilterFunction="GreaterThanOrEqualTo">
                                        <ItemStyle HorizontalAlign="Left" />
                                        <HeaderStyle Width ="10%" Wrap="true" />
                                    </telerik:GridBoundColumn>

Monitor Edit form changes

Hi,
I have a grid, similar to “Grid / User Control Edit Form” sample, and I want to implement confirmation, if user changes value in edit form and accidentally switch to other record without saving, something like this: http://aspnet.4guysfromrolla.com/articles/101304-1.aspx
Perhaps Telerik grid already have something built-in, which I missed? if no – how can I get clientid of textboxes on user control edit form?

Thanks
Alex

Column Widths

My scheduler becomes unintelligible if there are more than two overlapping appointments, because the columns have a fixed width that really barely handles two appointments side by side. I would like the columns to expand to accommodate an unlimited number of overlapping appointments.

Here's my Scheduler:

<telerik:RadScheduler ID="schPlanner" AllowDelete="true" AllowEdit="false" AllowInsert="false"

DataDescriptionField="Description" DataEndField="TimeEnd" DataKeyField="AppointmentKey"

DataStartField="TimeStart" DataSubjectField="Subject"

DayEndTime="22:00:00" DayStartTime="06:00:00" FirstDayOfWeek="Sunday" Height="100%"

OverflowBehavior="Expand" RowHeight="21px" runat="server" SelectedView="WeekView"

ShowAllDayRow="false" ShowFooter="false" ShowHeader="false" Skin="Web20" ToolTip=""

Width="800" WorkDayEndTime="22:00:00" WorkDayStartTime="06:00:00">

<Localization ConfirmDeleteText="Are you sure you want to delete this class?" />

<WeekView ColumnHeaderDateFormat="dddd" />

<AppointmentTemplate>

<%#Eval("Subject")%>

</AppointmentTemplate>

</telerik:RadScheduler>

Thanks,

Scheduler

Load RTF content in jquery dialog from ASP.net Gridview

I'm trying to load an RTF document that we retrieve from a database when a user clicks on an ImageButton on a row in a standard ASP.net gridview. The code seems to get called (RowCommand on server side) to load the RTF but when the dialog is displayed it is blank. It is as if the dialog has been loaded and the callback to load the RTF is ignored.

In ASPX page I have:

<div id="Viewer">

<twu:RadEditor runat="server" ID="DefViewer" Enabled="false" EditModes="Design" BorderStyle="None" Skin="Office2007">

<Content>

</Content>

</twu:RadEditor>

</div>

<asp:UpdatePanel ID="GridUpdatePanel" runat="server" ChildrenAsTriggers="False"

UpdateMode="Conditional">

<ContentTemplate>

<asp:GridView ID="ModelList" runat="server" AutoGenerateColumns="False" AutoGenerateSelectButton="false"

AllowPaging="true" CssClass="GridView" Width="600px" HorizontalAlign="Center" HeaderStyle-Height="40px">

<Columns>

<asp:TemplateField HeaderStyle-Width="20px">

<ItemTemplate>

<asp:ImageButton ID="InfoPopup" Width="15px" ToolTip="Click to display full model definition" Style="border: 0px"

runat="server" ImageUrl="~/Images/definition.gif" CommandName="Definition" />

</ItemTemplate>

</asp:TemplateField>

<asp:BoundField DataField="ModelID" />

<asp:TemplateField HeaderText="Model Name" SortExpression="Name" HeaderStyle-Width="350px">

<ItemTemplate>

<asp:LinkButton style="text-decoration:none" ID="ModelNameHyperLink" runat="server" CommandName="Select" CommandArgument='<%# Container.DataItemIndex %>' Text='<%# Eval("ModelName") %>' Font-Bold="True"></asp:LinkButton>

</ItemTemplate>

</asp:TemplateField>

<asp:BoundField DataField="ProviderId" />

<asp:BoundField DataField="Provider" HeaderText="Provider" HeaderStyle-Width="290px"/>

</Columns>

<AlternatingRowStyle CssClass="GridAlternating" />

<RowStyle CssClass="rowStyle" />

<PagerSettings Mode="NumericFirstLast" />

<SelectedRowStyle BackColor="#66CCFF" Font-Bold="true" ForeColor="Black" />

</asp:GridView>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="ModelList" EventName="PageIndexChanged" />

<asp:AsyncPostBackTrigger ControlID="ModelList" EventName="SelectedIndexChanged" />

<asp:AsyncPostBackTrigger ControlID="ModelList" EventName="RowCommand" />

</Triggers>

</asp:UpdatePanel>

Code Behind contains:

Protected Sub OnRowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles ModelList.RowCommand

Try

Select Case e.CommandName

Case "Definition"

Dim RowIndex As Integer = Integer.Parse(e.CommandArgument.ToString)

Dim ModelID As String = Me.ModelList.Rows(RowIndex).Cells(ModelListColumnEnum.ModelId).Text

Dim ProviderId As String = Me.ModelList.Rows(RowIndex).Cells(ModelListColumnEnum.ProviderId).Text

'Get the Definition for the specified model/provider and display it.

Try

Dim ModelDefinition As String = String.Empty

Dim ErrorDetails As String = String.Empty

If

JiatClient.GetModelDefinition(ProviderId, ModelID, ModelDefinition, ErrorDetails, Utilities.CurrentJIATUser(Session).UserID)

Then

Me.DefViewer.LoadRtfContent(ModelDefinition)

Else

Me.DefViewer.Content = "Either this model doesn't have a definition or it could not be loaded."

End If

ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, "FileOpen", "openDialog('Viewer');", True)

Catch ex As System.Exception

ThrowErrorMessage(ex.Message)

Finally

                        'We do some cleanup in here

End Try

openDialog is javascript jquery code in a separate js file. The code all seems to work except that the radeditor comes up empty. My only thought is that it is because the radeditor is loaded when the page is loaded and on every postback. the only way I could probably get this to work is to check in page load and see if I have a hiddenfield or something set to the RTF. Any ideas? I'm sure people will need more information.
