Hi,

I need to create a chart with the following properties:
  1. On the y axis, i need to show an integer say score
  2. On the x axis, i need to display the month on which the score was posted. The x axis can be static also and contain all the months.

I have a complex object which has both score and date attributes.

how can this be achieved? I am not able to find a solution for this problem. It is not present in a demo also.

Please help!

Thanks in advance

The Hyperlink column is kind of a pain in the ass if we can't set an Eval() statement on NavigateUrl directly in the markup...

Will this ever be fixed?  We can do it with a TemplateColumns controls fine...doesn't make it easy to use if you always have to use ItemDataBound everytime we need a simple nav column

What I'm trying to do

I have an ASP.NET page which shows a list of items.  Once the page has loaded, I perform an AJAX call to go and get the stock for every item.  When the AJAX call returns, we then display an "in stock" or "out of stock" icon with an associated tooltip for each item.  The tooltip will display the actual stock.

The problem
The tooltip is not just text but has formatting in it.  I have got my code to work in Firefox 4, but it doesn't work in Internet Explorer 8.

The code
The tooltip text template is:

In stock - <span style='color: #ff0000;'>[[stock]]</span> items

When the page first loads, I have a hidden label (style display = none) and I set this label's text property to that of the template text.

When my AJAX call returns, it runs a function.  This function iterates through each item and performs the following:

tooltip.show();
tooltip.set_contentElement(inStockTextCached);
var content = tooltip.get_content().replace(""[[stock]]"", fields[" + QoHDisplay.QuantityOrdinal + @"]);
tooltip.set_content(content);
tooltip.hide();

Okay, a quick explanation of this JavaScript:

tooltip.show();
If I don't add this then I get an error if I attempt the next line.  The error is "this._contentCell is null" and the solution was posted here: http://www.telerik.com/community/forums/aspnet-ajax/tooltip/client-side-set-content-to-dom-element.aspx

tooltip.set_contentElement(inStockTextCached);
Earlier on in the function I create a reference "inStockTextCached" to the label that holds the template text.  I then set the tooltip's content element to be the same.

In Firefox 4 and Chrome, calling set_contentElement(inStockTextCached) works fine but in InternetExplorer it does not work.

var content = tooltip.get_content().replace(""[[stock]]"", fields[" + StockOrdinal + @"]);
Here, I load the content of the tooltip and "[[stock]]" with the actual stock value returned from the AJAX call.

tooltip.set_content(content);
I then attempt to update the content of the tooltip

tooltip.hide();
I had to show the tooltip to prevent the error, but ideally I don't want it to show when it first loads....this is my attempt to therefore hide it (but that doesn't seem to have the desired effect).


Any help would be much appreciated.

Thanks in advance

I recently installed the update to 2011.1.315.40, and now find that RadRotator left and right buttons both show up on the left side of the RadRotator (see attached jpg). Before the update, in this project, the buttons were on the left and right sides as expected.

Has anyone else encountered this? Any ideas? Aspx for one of the pages follows:

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <div class="textcontent">
        <h1>Exterior Pictures</h1>
        <div>
            <telerik:RadRotator ID="RadRotator1" runat="server" Height="363px"
                Style="margin-left: 60px" 
                ItemHeight="363px" ItemWidth="550px" RotatorType="SlideShowButtons" 
               Width="590px" Skin="Default">
                <SlideShowAnimation Duration="3000" Type="Fade" />
                <ItemTemplate>
                <asp:Image ID="Image1" runat="server" 
                        ImageUrl='<%# DataBinder.Eval(Container.DataItem, "ImageUrl") %>'/>
            </ItemTemplate>
            </telerik:RadRotator>
        </div>
    </div>
</asp:Content>

I have used RadWindow many times and have always been able to do a close and rebind. This time however things are a little different. To rebind the data to a radgrid I need to call a SQL stored procedure.

I have all the Javascript and Ajax code set just like the online example. This usually works. The typical Ajax Request Handler looks like:

Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest
    If e.Argument = "Rebind" Then
        rgd_ABIUser.MasterTableView.SortExpressions.Clear()
        rgd_ABIUser.MasterTableView.GroupByExpressions.Clear()
        rgd_ABIUser.Rebind()
    ElseIf e.Argument = "RebindAndNavigate" Then
        rgd_ABIUser.MasterTableView.SortExpressions.Clear()
        rgd_ABIUser.MasterTableView.GroupByExpressions.Clear()
        rgd_ABIUser.MasterTableView.CurrentPageIndex = rgd_ABIUser.MasterTableView.PageCount - 1
        rgd_ABIUser.Rebind()
    End If
End Sub

This works when the radgrid is bound to a SQLDataSource. However, I need to rebind the grid using:

Private Function GetUser() As DataTable
    Dim DatabaseName As String = rcb_Database.SelectedValue
    Dim SC As String = rcb_Site.SelectedValue
    Dim connectionString = New SqlConnection("server=DO-IT-AB\MSSQLAB;database=AeriesAdmin;UID=XXXX;PWD=XXXX;")
    Dim command = New SqlCommand("aa_abi_users_by_site", connectionString)
    command.CommandType = CommandType.StoredProcedure
    command.Parameters.Add("@DBName", SqlDbType.VarChar).Value = DatabaseName
    command.Parameters.Add("@SC", SqlDbType.VarChar).Value = SC
    command.Connection.Open()
    Dim myDataAdapter As New SqlDataAdapter(command)
    Dim myDataSet As New DataSet
    Dim dtData As New DataTable
    myDataAdapter.Fill(myDataSet)
    Return myDataSet.Tables(0)
    command.Connection.Close()
End Function

I tried to modify the handler to call my function but this does not work:

Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest
    If e.Argument = "Rebind" Then
        rgd_ABIUser.MasterTableView.SortExpressions.Clear()
        rgd_ABIUser.MasterTableView.GroupByExpressions.Clear()
        rgd_ABIUser.DataSource = GetUser()
        rgd_ABIUser.Rebind()
    ElseIf e.Argument = "RebindAndNavigate" Then
        rgd_ABIUser.MasterTableView.SortExpressions.Clear()
        rgd_ABIUser.MasterTableView.GroupByExpressions.Clear()
        rgd_ABIUser.MasterTableView.CurrentPageIndex = rgd_ABIUser.MasterTableView.PageCount - 1
        rgd_ABIUser.DataSource = GetUser()
        rgd_ABIUser.Rebind()
    End If
End Sub

Any help performing a RadWindow Close and Rebind.

I would like to remove the "Select All" checkbox from the header, and add an expand all button to the header above the "+" icons.  What is the best way to do this?  There doesn't seem to be a "header template" for this control.

Hello,

I have seen this topic in many different forum posts and demos on the site and I have tried so many different things I am just totally confused about how to make this work.

I have a RadGrid in which I am doing Inserts and Updates through an ObjectDataSource.  In the FormTemplate among other controls I have two dropdownlists that are both populated by their own ObjectDataSources.  The SelectParameter of the second dropdownlist is the selectedvalue from the first dropdownlist.  Before I converted this page into a RadGrid I simply used a ControlParameter for the ObjectDataSource of the second dropdownlist referencing the first one.  Now it seems that I can't do that within the FormTemplate of the grid for multiple reasons.

So what I need to accomplish is the following:

1.  I want the dropdowns to show the correct item as selected when that item is "edited".
2.  I want the second dropdown to be repopulated with the correct items when the first dropdown is changed.
3.  I want the correct item saved to the database on insert and update.

These are pretty obvious but at this point I'm not sure what I need to do to make that happen.

Here is the important snippet of my aspx code:

<FormTemplate>
    <asp:Panel ID="pnlEditPanel" runat="server" DefaultButton="btnUpdate" CssClass="edit_panel" TabIndex="100">
        <table border="0" cellspacing="0" cellpadding="0">
        <tr>
            <td>Group:</td>
            <td>
                <asp:ObjectDataSource ID="odsGroupList" runat="server" SelectMethod="dsGroupList" TypeName="NUFOLibrary.CMembers">
                    <SelectParameters>
                        <asp:SessionParameter Name="sUserID" SessionField="UserID" Type="String" />
                        <asp:Parameter Name="sPublic" DefaultValue="0" Type="String" />
                    </SelectParameters>
                </asp:ObjectDataSource>        
                <asp:DropDownList ID="lstGroups" runat="server" DataSourceID="odsGroupList" DataTextField="Group" DataValueField="ID" AutoPostBack="True" AppendDataBoundItems="true" OnSelectedIndexChanged="lstGroups_SelectedIndexChanged" SelectedValue='<%# Bind("Group_ID") %>'>
                    <asp:ListItem Value="0" Text="(Select One)" />
                </asp:DropDownList>                                
            </td>
        </tr>  
        <tr>
            <td>Position:</td>
            <td>
                <asp:ObjectDataSource ID="odsPositionList" runat="server" SelectMethod="dsPositionList" TypeName="NUFOLibrary.CMembers">
                    <SelectParameters>
                        <asp:SessionParameter Name="sUserID" SessionField="UserID" Type="String" />
                        <asp:ControlParameter Name="sGroupID" ControlID="lstGroups" Type="String" />
                    </SelectParameters>
                </asp:ObjectDataSource>        
                <asp:DropDownList ID="lstPositions" runat="server" DataSourceID="odsPositionList" DataTextField="Position" DataValueField="ID" SelectedValue='<%# Bind("Position_ID") %>'>
                    <asp:ListItem Value="0" Text="(Select One)" />
                </asp:DropDownList>                                    
            </td>
        </tr>

So on an edit/update command this works.  It displays the correct item as selected in the second dropdownlist.  I am fine here because I actually set enable=false on an edit because they are not allowed to edit that field so I don't have to worry about changing the first dropdownlist and repopulating the second.

But the problem is on an insert.  When I try to add a new entry I immediately get an error that the second dropdownlist has a SelectedValue that is invalid because it doesn't exist in the list of items.

Maybe this is because I am setting the default empty value (or in my case 0)?

Here are the important parts of my codebehind:

Protected Sub gvMembers_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs) Handles gvMembers.ItemCommand
    If (e.CommandName = RadGrid.InitInsertCommandName) Then
        e.Canceled = True
        Dim newValues As System.Collections.Specialized.ListDictionary = New System.Collections.Specialized.ListDictionary()
        newValues("Group_ID") = "0"
        newValues("Facility_ID") = "0"
        newValues("Position_ID") = "0"
        e.Item.OwnerTableView.InsertItem(newValues)
    End If
End Sub
Private Sub gvMembers_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles gvMembers.ItemDataBound
    If e.Item.DataItem Is Nothing Then Exit Sub
    If "Membership".Equals(e.Item.OwnerTableView.Name) Then
        If (TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode) Then
            Dim editFormItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
            DirectCast(editFormItem.FindControl("lstGroups"), DropDownList).Enabled = False
            DirectCast(editFormItem.FindControl("lstFacilities"), DropDownList).Enabled = False
            DirectCast(editFormItem.FindControl("lstPositions"), DropDownList).Enabled = False
            DirectCast(editFormItem.FindControl("rdpStartDate"), RadDatePicker).Enabled = False
            DirectCast(editFormItem.FindControl("rdpEndDate"), RadDatePicker).Enabled = True
        End If
        If (TypeOf e.Item Is GridEditFormInsertItem) AndAlso (e.Item.OwnerTableView.IsItemInserted) Then
            Dim editFormItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
            DirectCast(editFormItem.FindControl("lstGroups"), DropDownList).Enabled = True
            DirectCast(editFormItem.FindControl("lstFacilities"), DropDownList).Enabled = True
            DirectCast(editFormItem.FindControl("lstPositions"), DropDownList).Enabled = True
            DirectCast(editFormItem.FindControl("rdpStartDate"), RadDatePicker).Enabled = True
            DirectCast(editFormItem.FindControl("rdpEndDate"), RadDatePicker).Enabled = True
        End If
    End If
End Sub
Protected Sub lstGroups_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
    Dim lstGroups As DropDownList = DirectCast(sender, DropDownList)
    Dim editItem As GridEditFormItem = DirectCast(lstGroups.NamingContainer, GridEditFormItem)
    Dim lstFacilities As DropDownList = DirectCast(editItem.FindControl("lstFacilities"), DropDownList)
    Dim lstPositions As DropDownList = DirectCast(editItem.FindControl("lstPositions"), DropDownList)
    Dim rdpStartDate As RadDatePicker = DirectCast(editItem.FindControl("rdpStartDate"), RadDatePicker)
    Dim rdpEndDate As RadDatePicker = DirectCast(editItem.FindControl("rdpEndDate"), RadDatePicker)
    'Dim odsPositionList = New ObjectDataSource
    'odsPositionList.ID = "odsPositionList"
    'odsPositionList.SelectMethod = "dsPositionList"
    'odsPositionList.TypeName = "NUFOLibrary.CMembers"
    'odsPositionList.SelectParameters.Add(New Parameter("sUserID", TypeCode.String, HttpContext.Current.Session("UserID").ToString))
    'odsPositionList.SelectParameters.Add(New Parameter("sGroupID", TypeCode.String, lstGroups.SelectedValue))
    'lstPositions.DataSource = odsPositionList
    'lstPositions.DataBind()
    If lstGroups.SelectedValue = "3" Then
        lstFacilities.Enabled = False
    Else
        lstFacilities.Enabled = True
    End If
    If lstGroups.SelectedValue = "4" Then
        rdpStartDate.DbSelectedDate = ""
    Else
        rdpStartDate.DbSelectedDate = Now().ToString
    End If
    rdpEndDate.DbSelectedDate = ""
End Sub

I had tried moving the populating of the second dropdown to the SelectedIndexChanged of the first dropdownlist (as you see commented out) but that causes the problem that when it tries to save it doesn't save the item to the database because I had to remove the SelectedValue='<%# Bind("Position_ID") %>' for the aspx page because of another error.

Someone please help me to figure out the best way to accomplish this.  Do I need to do the entire thing in code including the insert/update tot he database instead of letting the grid do it?

thanks,

Steve
