Hi
With you build in provider for radScheduler, what technology is used to optimize perfomance with large databaseses.
Example: I have implimented radscheduler for a NPO organization with 400 branches. each branch enter their events, but can also see other branches event. (Permissions handled by me). Public can see all which ever branches they select. (All branches in a region etc).In one year, a brach could have 100-200 events. (That is 100 x 400 events (40000) events per year. After 3 years the events table will be big. What can be done MORE, to save on database, web and network utilization? (Not only for performance, but also for appearance, I already prevent users from selecting more than 15 branches at a time, so my SQL command already limit this to 15 x 400 x years.

I can not delete historical events, because of other database relations (courses and historical course rsvps are connected to the eventid in my db, and those historical information is used all the time)

1. If you look at a month, week of timeline view, what memory is alllocated on th server (only the date range, or everything in memory)
2. How much is in sessions memory? etc.

Do you think it is advisable to tailor my SQL statements to just fetch data within a certain date range?

In my provider, I put some additional information about the appointment into the Attributes collection like this:

  appointment.Attributes["somekey"] = somevalue;

I want to access those attributes in events raised by the scheduler.
So I was thinking I could just have something like

  somestring = appointment.Attributes["somekey"];

But this always comes back Null. I can see that the attributes have been populated in the debugger, I just can't figure out how to retrieve values. Can someone show me please? Thanks!

Hello,

I'm using the RadMenu to open the RadWindow. I'm setting the onclick to a javascript function when the menu item should open a new page, if it should navigate to a different page I use the NavigationURL. The server side code dynamically adds the windows to the RadWindowManager based on my Menu.

I would like one of my pages to appear as a modal dialog which dims the parent window (this works great), but I would like another menu item to open a new window that is outside of the parent window. Is this possible? All of the examples of the RadWindow I've seen only allow the window to be inside the page window - is it possible to spawn a new "blank" window?

Server Side (Dynamically Creating Windows):
RadWindow rw = new RadWindow();
rw.ID = "Window" + menuItem.Uid;
[excluded settings here...]
RadWindowManager1.Windows.Add(rw);
newMenuItem.Attributes.Add("onclick", "OpenWindow('"+ menuItem.Uid + "');");

<script type="text/javascript">
    function OpenWindow(menuId) {
        radopen(null,'Window'+menuId);
        return false;    
    }
</script>

<telerik:RadMenu ID="mnuRoot" runat="server" Skin="CustomMenu" EnableEmbeddedSkins="false" Width="100%">
</telerik:RadMenu>

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" Skin="Default">   
</telerik:RadWindowManager> 

Thanks,
Nathan

I have a radcombobox and in that I have placed one checkbox after databinding I want to insert one more checkbox inside that radcombobox to select all items.

<telerik:RadComboBox ID="cmbRoleName" EmptyMessage="- please select group -" runat="server"
                                     AutoCompleteSeparator="true" HighlightTemplatedItems="true"
                                    AutoPostBack="True" AllowCustomText="true" OnClientDropDownClosed="onDropDownClosing">
                                    <Items>
                                        <telerik:RadComboBoxItem Value="0" Text="-- Select All Users --" />
                                    </Items>
                                    <ItemTemplate>
                                        <table border="0" cellpadding="0" cellspacing="0">
                                            <tr>
                                                <td>
                                                    <asp:CheckBox runat="server" ID="chkRole" Text='<%#DataBinder.Eval(Container.Dataitem,"RoleName")%>'
                                                        Onclick="chkBox_Click(this)" />
                                                </td>
                                            </tr>
                                        </table>
                                    </ItemTemplate>
                                </telerik:RadComboBox>

I have tried to do this on server side like this but the problem is that two checkboxes are appearing one with text and without text. Any Help would be really appreciated.

Protected Sub CreateSelectAllUsersCheckBox()
        Dim chkSelectAllUsers As New CheckBox
        chkSelectAllUsers.Text = "Select All Users"
        chkSelectAllUsers.ID = "chk1"
        Dim radComboBoxItem As New RadComboBoxItem
        radComboBoxItem.Text = "Select All Users"  
radComboBoxItem.Controls.Add(chkSelectAllUsers)     
        cmbRoleName.Items.Insert(0, radComboBoxItem)
    End Sub

Dear Experts,

I am implementing a web application. Because the system responsiveness in for me critical I decided to use RadrGrid with Client side binding. As the table shows some related data I would implement some filter templates with combo boxes. I was spending some time in finding a demo or guidelines to implement this scenario, but I found nothing useful.

  

Can anybody address me to any demo or at least give me some guidelines.

Any help would be appreciated.

Weird behavior that just started happening after I made some code changes.

I have a tabstrip with 2 tabs and a grid inside each tab, and when I click on the filter button, the dropdown menu doesn't pop up. If I click on the other tabstrip, it reloads the other grid, and then it starts working fine if I click back on the tab  to reload it again. I am trying to figure out what is causing this, and I will let everyone know if I find out. Just wanted to know if you have any ideas what's causing this.

Hello,

I have used rad grid with insert , update option using edit form template.While Add/Edit time Depending on Radio Button Selection I need to Enable , Disable Validation. I have putted java script for show hide panels and enable , disable validation for radio button selection.  Insert , Update option works perfect when validation are enable but when i am selecting radio button option which is disabling my validation then by clicking on Insert , Update button my insertcommand and updatecommand are not working. By clicking on insert or update button it direct comes to itemcommand event not on insert or update command.

I have debug javascript there is no issue in java script. page is getting postback and rather than insert or update command it comes to item data bound and item command.

Any Idea why rad grid insert , update command not working after disabling validation?

Hi,

I use radcombox control in my page. I filled items in this combobox at page_load event. For example; items are SLOVENIA, SPAIN, SWITZERLAND..

I type only S then focus on SLOVENIA... thats ok.. But I want to focus SPAIN so I want to type second character but it doesn't allow me.

This problem occur in some clients ( Internet Explorer v 8.0.7600.16385 )

If I change browser to Firefox, there is no problem. What do I have to change settings of IE ?
I am using v.  Telerik 2009.02.0701.35

Hi

I followed the link http://www.telerik.com/help/aspnet-ajax/grdfilteringbylisttextfieldforgriddropdowncolumn.html to try to filter a drop down column as below:

                <telerik:GridDropDownColumn UniqueName="LocationID" ListTextField="LocationName"
                    AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false"
                    ListValueField="LocationID" HeaderText="Location" DataField="LocationID" ReadOnly="true">
                </telerik:GridDropDownColumn>
                <telerik:GridBoundColumn DataField="LocationName" HeaderText="LocationName" SortExpression="LocationName"
                    UniqueName="LocationName" Display="false">
                </telerik:GridBoundColumn>

and have the item command event handler as below:
        protected void RadGridUsers_ItemCommand(object source, GridCommandEventArgs e)
        {
            if (e.CommandName == RadGrid.FilterCommandName)
            {
                Pair command = (Pair)e.CommandArgument;
                if (command.Second.ToString() == "LocationID")
                {
                    e.Canceled = true;
                    GridFilteringItem filter = (GridFilteringItem)e.Item;
                    ((filter["LocationName"].Controls[0]) as TextBox).Text = ((filter["LocationID"].Controls[0]) as TextBox).Text;
                    command.Second = "LocationName";
                    filter.FireCommandEvent("Filter", new Pair(command.First, "LocationName"));
                }
            }
        }

The only difference is that I have not got a declared data source but binding drop down column by code:
 

        protected void RadGridUsers_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem && !e.Item.IsInEditMode)
            {
                GridDataItem item = (GridDataItem)e.Item;
                Literal litrl = (Literal)item["LocationID"].Controls[0];

                CommonDataService commonDataService = new CommonDataService();
                object dataBindingResult = DataBinder.Eval(item.DataItem, "LocationID");
                if (dataBindingResult != null)
                {
                    litrl.Text = commonDataService.LocationGetById(Int32.Parse(dataBindingResult.ToString())).LocationName;
                }
            }
        }

When I try to filter Location column, it always brings back all records.

Cheers

Hey guys,

I'm redoing some code that was written by a previous coder. Basically, we have a poll, where we see the question (an optional question image) and 2-10 answers (with their optional images). There's also a ticker that ticks every 5 seconds. There's tons of ajax programmed in which causes the RadioButtonList and the button label (lblMessage) to refresh every 5 seconds. The images and the answer text are loaded into the list items of the RadioButtonList. So every 5 seconds or anytime a different radio button is selected, the images are repainted. Which makes the website really hard to look at more than a minute or two.

We do need the ajax for the radiobuttonlist due to the timer, unless there's another way to go around this. If the poll ends and the user selects a different answer, it will disable the radio buttons and notify that the poll is over. So I'm wondering if there's anyway to separate the images from the RadioButtonList, or another way to keep the images from repainting without losing functionality.



and here is the code behind



Thanks for your time!
