Grid with usercontrol update not refreshing

Hi all,

I've got a grid more or less with the same functionality as the one that you've got in the demo "Usercontrol edit form", this page is under a Master page that has got some buttons like a search button that raises the event search and a Reload is launched with all the needed params that fills a DataSet and binds to the datagrid.
My problem is that this search is not working, the event is fired, the dataset is filled with correct data, the Grid is rebinded but it doesn't show the correct data, it doesn't reload, I tried to solve with an update panel, it works pretty good but when I try to edit a row it throws me a jscript error that says me that "can't find update panel Ctl00_00_...", and if I haven't got the update panel my search event doesn't work.

This is the content of the page:

Is there anyway to use the radajaxmanagerproxy to make the grid reload when the Masterfind event is raised?

Thanks in advance,

Context menu hide ColumnsContainer

I don't want to display the column selection option in context menu.

I am able to do that within HeaderContextMenu_PreRender

private void HeaderContextMenu_PreRender(object sender, EventArgs e)

{

GridHeaderContextMenu menu = sender as GridHeaderContextMenu;

foreach (RadMenuItem item in menu.Items)

if (item.Text == "Columns")

{

item.Visible = false;

}

But when I click on the menu I get this error in dynamic javascript.
code line: var h=m.findItemByValue("ColumnsContainer").get_items();
Error: Microsoft JScript runtime error: 'findItemByValue(...)' is null or not an object

Any suggestions?

thanks

RadScheduler WebService Result on Insert

We are using the RadScheduler with Web Services binding. On inserting a new appointment, we would like to retrieve the ID of the appointment on the client side after the Web Service request is complete. Can we retrieve this in the result sent back from the service call in the OnClientRequestSuccess method? If so, what is the best approach for doing this? We noticed that the Insert method is passing back IEnumerable<AppointmentData>. How can this data be used?

If the OnClientRequestSuccess method is not the best approach, what other options are there?

By the way, we noticed that it is possible to return a SchedulerResult object with the GetAppointments method. Can that be done with the InsertAppointment method? If so, that would solve our problem.

Need help with simple line chart

I have a stored procedure that selects two columns from a single table - size (int) and date. All I want to do is plot a line graph with the size, and have the X axis item labels show the dates recorded.

So, the data looks like this:

    
            size | date 
        
            224 | 1-5-10 
        
            250 | 1-10-10 
        
            156 | 1-22-10

And this is what I ended up with when I tried to use the Wizard (bound to a SqlDataSource):

    
             <telerik:RadChart ID="RadChart1" runat="server" DataSourceID="SqlDataSource1"  
        
                                DefaultType="Line" Skin="Default"> 
        
                                <Series> 
        
                                    <telerik:ChartSeries Name="Size" DataYColumn="size" Type="Line"  
        
                                        DataXColumn="size"> 
        
                                        <Appearance> 
        
                                            <FillStyle MainColor="213, 247, 255"> 
        
                                            </FillStyle> 
        
                                        </Appearance> 
        
                                    </telerik:ChartSeries> 
        
                                </Series> 
        
                                <PlotArea> 
        
                                    <XAxis AutoScale="False" DataLabelsColumn="size"> 
        
                                        </XAxis> 
        
                                </PlotArea> 
        
                            </telerik:RadChart>

What I want is to have the dates as the X axis labels, but I can't figure out how to do it. It seems like this should be incredibly simple, but I just find the chart syntax really confusing. Any help would be very much appreciated.

Row Hover Style disappears when hovering over RadioButtonList

Style issue here:

I've got a radGrid with a Template column that contains an ASP.NET RadioButtonList (simply Yes/No radio buttons). I've turned on AllowHoverStyle in the ClientSettings of the radGrid. The entire row does hover, EXCEPT when I hover over the RadioButtonList, in which case the hover style goes away.

I'm usually pretty good with styling issues, but I'm at a loss on this one. The strange thing is I have other columns that some have buttons, images, dropdown, and hovering over any of these items does NOT make the row hover style go away; it stays and is great. It only disappears when it's over the RadioButtonList. Well technically since the RadioButtonList control renders with a table w/radio buttons inside table cells, the radGrid's hover style appears to disappear when the mouse hovers over this RadioButtonList rendered radio button or radio button's label (still works if Only over the table containing the buttons and labels)

I've already tried setting z-index on the radios and labels to inherit, but that didn't work. not sure what else would cause the full row's hover style to go away?

Any ideas are greatly appreciated. Thanks.

{

int itemCount = (sender as RadGrid).MasterTableView.GetItems(GridItemType.Item).Length + (sender as RadGrid).MasterTableView.GetItems(GridItemType.AlternatingItem).Length;

foreach (GridItem item in (sender as RadGrid).Items)

{

if (item is GridDataItem && item.ItemIndex < itemCount - 1)

{

((item as GridDataItem)["C_Name"] as TableCell).Controls.Add(new LiteralControl("<table style='display:none;width: 730px'><colgroup><col /><col /><col /></colgroup><tr><td>"));

}

Can you please help?

Previous verison of the control if DecimalDigits is not set it will not force any decimal places with AllowRounding="false".

OnClientSelectedIndexChanged disables ComboBox pull down

My fault. I had a javascript error on the page.

When I add the attribute OnClientSelectedIndexChanged to a RadComboBox, the pull down functionality is disabled. Unfortunately, when I create a simple example, the combo box continues to work. Something on my page is interacting with the RadComboBox.

Any Ideas?
