Questions on UI for ASP.NET AJAX Forum

I have a multitude of problems, but I will start with the most important.

1) I have a rotator that shows images that have descriptions. On mouseover tooltip is suppose to load the description. On every site expect the root of the site, this works. On the root, it appears that the value being passed to the user control is getting lost in translation; for example, the value might be 18 but its passing 91. I have copied the code sections exactly from the children sites and it still has problems. Please help!!

protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)

{

this.UpdateToolTip(args.Value, args.UpdatePanel);

}

private void UpdateToolTip(string elementID, UpdatePanel panel)

{

Control ctrl = Page.LoadControl("ImageDesc.ascx");

panel.ContentTemplateContainer.Controls.Add(ctrl);

ImageDesc img = (ImageDesc)ctrl;

img.IDNum = elementID;

}

protected void RadRotator1_ItemDataBound(object sender, Telerik.Web.UI.RadRotatorEventArgs e)

{

Control target = e.Item.FindControl("RadBinaryImage1");

HiddenField id = (HiddenField)e.Item.FindControl("HiddenField2");

HiddenField id2 = (HiddenField)e.Item.FindControl("HiddenField1");

if (!Object.Equals(target, null))

{

if (!Object.Equals(this.RadToolTipManager1, null))

{

//Add the button (target) id to the tooltip manager

this.RadToolTipManager1.TargetControls.Add(target.ClientID, id2.Value+id.Value, true);

}

<div class="pics">

<telerik:RadRotator ID="RadRotator1" Enabled="false" runat="server" ItemWidth="207" Height="122"

ItemHeight="122" DataSourceID="SqlDataSource1" Skin="Office2007" OnItemDataBound="RadRotator1_ItemDataBound"

Width="620px" BorderColor="#FF3300" FrameDuration="7000">

<ItemTemplate>

<telerik:RadBinaryImage ID="RadBinaryImage1" DataValue='<%# Eval("Image") %>' runat="server" />

<asp:HiddenField ID="HiddenField1" runat="server" Value='<%# Eval("ImageID") %>' />

<asp:HiddenField ID="HiddenField2" runat="server" Value='<%# Eval("ImageDesc") %>' />

</ItemTemplate>

</telerik:RadRotator>

<telerik:RadToolTipManager ID="RadToolTipManager1" OffsetY="-1" HideEvent="Default"

runat="server" OnAjaxUpdate="OnAjaxUpdate" RelativeTo="Element"

Skin="Office2007" Position="BottomCenter">

</telerik:RadToolTipManager>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:RootConnection %>"

SelectCommand="Select Top 15 Image,ImageID,ImageDesc + 'ID:'+convert(varchar(10),ImageID) as 'ImageDesc' From CMS_Header_Images Where Archive='No' and SiteID=@SiteID ORDER BY NEWID()">

<SelectParameters>

<asp:ControlParameter ControlID="RotatorSiteID" Name="SiteID" PropertyName="Value" />

</SelectParameters>

</asp:SqlDataSource>

<asp:HiddenField ID="RotatorSiteID" runat="server" />

</div>

Again, this is proven code that works on all sites expect the root. Any ideas will be greatly appreciated.

UPDATE : My latest guess is that it is a databinding problem from the datasource to the rotator. (12.3.10 10:30 CST)

[Solved] Extreme slow Item Edit (EditForm.aspx) Page

Hi all,

i have a Custom List with nearly 80 Fields. 20 of these 80 Fields are Rich-Text Fields. On my Site Collection is the RAD Editor for Lists activated. When i now want to Add or Edit an Item in this list, it takes 1:15 min to the point where i am able to do some input.

When i disable the RAD Editor Feature it takes nearly 25 seconds. This is a long time, too, but much more less than 1:15 min. When i look at the generated Code which is sent to the bworser, i see for each RichText Field a huge amount of RADEditor generated Code (JS?).

Is it possible for example to have this code only one time instead of n-times (amount of the RichText Fields)?

How to improve the performance? We are using the Version 5.5.1 of the RADEditor.

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
