Rad Window State Issue

Hi,

I have a requirement where I need to have a master page and a RAD menu control on the master page. Now I need a new RAD window on click of any menu item from server side irrespective of the fact whether I am clicking same menu item or any other menu item.  

 

I am creating a new RAD window on click event of every menu item click event from server side code and able to successfully create a new RAD window when I am clicking first time on any menu item. But whenever I clicked on any other menu item or same menu item again, my previously opened RAD window get lost and new rad window appears. I think it is a state issue, seems like page is not able to maintain RAD windows on the post back.

 

I have also tried creating RAD windows from client side java script as well. I am able to create multiple rad windows using java script on click of any of my menu item but all RAD windows created with java script are getting lost on click of browser’s refresh button and F5 button.

 

Please let me know the best way to create multiple RAD windows from server side and client side as well along with state management. Please help me out to maintain rad windows even after post back of page where these windows exist.

InsertCommand not triggered
Hi all:
I must be doing something wrong in the settings as I can't seem to figure out why my listbox isn't auto updating.  I've used this demo to help me on my way, and I successfully have the delete statement working great.  I need to get the "insert" to work.  Here's my code:

.aspx
<telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" />
<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1" LoadingPanelID="RadAjaxLoadingPanel1">
<telerik:RadListBox ID="pasLead_rlb" runat="server" Height="150px" Width="250px" AllowTransfer="true" TransferToID="pasLead_rlbDestination"
    DataSourceID="paslead_DS" DataTextField="paslead" DataValueField="contactID">
</telerik:RadListBox>
<telerik:RadListBox ID="pasLead_rlbDestination" runat="server" Height="150px" Width="250px" DataKeyField="contactID" AutoPostBackOnTransfer="true" AutoPostBack="true"
    DataSourceID="pasleadSelected_DS" DataTextField="paslead" DataValueField="contactID" AllowAutomaticUpdates="true" AutoPostBackOnDelete="true" AllowDelete="true">
</telerik:RadListBox>
</telerik:RadAjaxPanel>

sqldatasource
<asp:SqlDataSource ID="pasleadSelected_DS" runat="server"
    ConnectionString="<%$ ConnectionStrings:myconnection %>"
    SelectCommand="SELECT contacts.id AS contactID, contacts.name + ' (' + groups.short_name + ')' AS paslead
                    FROM contacts,
                        groups,
                        area_contact_map acm
                    WHERE contacts.groupID = groups.id
                        and contacts.id = acm.contactID
                        and areaID = @id
                        and (acm.blnRemoved IS NULL OR acm.blnRemoved = 0)
                    ORDER BY paslead"
    DeleteCommand="UPDATE area_contact_map SET update_date = getDate(), update_user = @u, blnRemoved = 1 WHERE areaID = @aid AND contactID = @contactID"
    InsertCommand="INSERT INTO area_contact_map (areaID, contactID, create_date, create_user, blnRemoved) VALUES (@aid, @contactID, getDate(), @u, 0)">
    <SelectParameters>
        <asp:Parameter Name="id" Type="String" />
    </SelectParameters>
    <DeleteParameters>
        <asp:Parameter Name="aid" Type="String" />
        <asp:Parameter Name="contactID" Type="String" />
        <asp:Parameter Name="u" Type="String" />
    </DeleteParameters>
    <InsertParameters>
        <asp:Parameter Name="aid" Type="String" />
        <asp:Parameter Name="contactID" Type="String" />
        <asp:Parameter Name="u" Type="String" />
    </InsertParameters>
</asp:SqlDataSource>

.vb
aid = Request.QueryString("i")
pasuser = Membership.GetUser.ProviderUserKey.ToString()
 
areaDS.SelectParameters("id").DefaultValue = aid
pasleadSelected_DS.SelectParameters("id").DefaultValue = aid
pasleadSelected_DS.DeleteParameters("aid").DefaultValue = aid
pasleadSelected_DS.DeleteParameters("u").DefaultValue = pasuser
pasleadSelected_DS.InsertParameters("aid").DefaultValue = aid
pasleadSelected_DS.InsertParameters("u").DefaultValue = pasuser

The action I need to track automatically, is when the user moves an item from paslead_rlb to paslead_rlbDestination.  Help!  Thanks!

Problem with Grid Header
I am having a problem with the header portion of the radgrid.

When the page is first displayed the right-hand portion of the header has been eliminated and replaced with white space.  Attached graphic "HeaderWidth1.png" shows this and also shows the Developer Tools display with the header segment highlighted.  You can see the width is set at "663px".

If I change the "663px" to "100%", the header will be displayed at full width (refer to attached graphic "HeaderWidth2.png").

I have tried coding a special css class for this item setting its width to 100% to no avail.

The code for the .aspx file is displayed immediately below.  Can anyone tell me why this issue is happening and how I can eliminate it?

Thanks in advance!

Lynn

Problem with Radgrid nestedview template
Hi,

    I am having a problem with RadGrid control. I am using radgrid with filter and sorting option. Now my grid is having 2 rows for a particular record (as shown in lookup2.png). In the starting when we come onto the page it looks like a general grid with filter option on the top. But when we select edit in dropdownlist present in action column. then that row comes down and another edit record row become visible with prepopuleted fields. now when i click on update, It updates the record in database and edit row becomes invisible.
I tried to solve this my using nestedviewtemplate example given in the forum but i did not get it. 
   So can u make a dummy application give it to me because this concept is the main concept of the project and nearly 80% grids of the project is based on this concept.
  So please resolve it asap.

With Regards

ContentArea background color
Ive read multiple threads on here about setting the background color of the editor but with no success.

As my page background is dark, text is unreadable so i want to make the background white.

Ive created a EditorContentArea.css file but not sure where i place this. Its currently in the web root but isnt being picked up.

do i need to set the path to this somewhere in an editor property or does the editor expect to load it from a certain location?

has anyone succeeded in doing this?

my only alternative is to try another editor if i can't find a solution to this

RadDatePicker with HtmlTextWriter
Hi,

Problem about : "RadDatePicker" 
I am trying to create a html table with "RadDatePicker" dynamically(in code behind) and tried to pass that HTML table as string to jquery.

Its working fine for ASP controls but whenever I tried to add "RadDatePicker" it is giving error.
My code -
[System.Web.Services.WebMethod]
        public static string  txtNoOfInstallment_OnTextChanged(int noOfInstallments)
        {          
            try
            {
                Table tab = new Table();
 
                for (int i = 1; i <= noOfInstallments; i++)
                {
                    TableRow tr = new TableRow();
                    TableCell td1 = new TableCell();
                    TableCell td2 = new TableCell();
                    TableCell td3 = new TableCell();
                    TableCell td4 = new TableCell();
 
                    Label lblAmt = new Label();
                    lblAmt.Text = "Installment" + " " + i;
 
                    TextBox txtAmount = new TextBox();
                    txtAmount.ID = "txtAmount" + i;
 
                    Label lblDate = new Label();
                    lblDate.Text = "Due date";
 
                    RadDatePicker dtPickerIstallmentDate = new RadDatePicker();

 Hi,


I am loading a Hierarchical RadGrid inside a dynamically created RadDock, and the RadGrid is inside a user control. So when the RadDock is expanded the usercontrol(with the RadGrid) is loaded. And on expanding the Hierarchical RadGrid the next level of items is not shown. This is because of ispostback property which is always true for the usercontrol. And so the RadGrid inside the usercontrol is creating problem. It is working fine for a plain grid without any levels, but i am in need of using a Hierarchical RadGrid. Would appreciate if any help is provided for this. I want to know is that scenario possible or not and the way for doing it if possible. Thank you. Attaching the code below.

Sharepoint 2010 with RadChart issues
I am having issues trying to add a RadChart to a Sharepoint 2010 webpart control.

I found this telerik forum post and have followed the directions so far, but there is a bad link in this post and it seems that this is where I'm stuck. 

I am getting this error from the server:

Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.

Is there an updated link to AdvancedSessionState or can someone tell me if something is wrong in what I'm doing?

FocusControl() not working in IE7
Hi,

I have a DotNetNuke module with quite some controls being loaded dynamically. Each of the input controls has autopostback set. In practice, a user will tab to a next control.

In javascript, I put the ID of the newly focussed control in a hidden field.
Then autopostback occurs, and I use RadAjaxManager.FocusControl() to set the focus to the control in the hidden field.

This works just fine in FireFox and IE9, but doesn't work in IE7 (or IE9 with compatibility mode set to true).

Any ideas?

Thanks!
