CSV Export not exporting commanditem template.

Hello All,

Presently I am having a telerik radgrid with a commanditem template above the grid header for some extra information.But the problem is that while exporting to CSV , the header information inside the commandItem template is not being exported.However the export is working just fine with PDF and Excel .Here is the code I am using.

<telerik:RadGrid ID="ModifiedContentsReportGrid" runat="server" AutoGenerateColumns="false"

<NoRecordsTemplate>
<asp:Literal runat="server">
No records to display.</asp:Literal>
</NoRecordsTemplate>
</MasterTableView>
<PagerStyle Mode="NextPrevAndNumeric" />
</telerik:RadGrid>

Can anyone provide some some inputs or solution to this problem?

[Solved] Dynamic data columns at runtime for grid data source

I have form designer that allows users to create any form they want the will then be used as a member form. The member form is then used to join a group. All this is working fine (except for a problem with RadDropDownList) and I have many members in the test database. I now wish to use the grid to display the users in a group member list for member management.

The problem I cannot solve is how to create the source with data for the grid. Every example I can find seems to know all its columns in advance. I actually do not know any of my columns in advance. I have a list of form rows that each have a name with a type and the ability to populate instances of the list.

I would also like to create a column selector. I wonder if there are any examples of that around.

Thanks,
George

ERROR=Cannot perform this operation when DataSource is not assigned.

I am getting this exception intermittently when binding a RadListView. I create a data table, fill it with some data, assign it as the data source, and then do a data bind. I know the code always returns a data table, even if it is empty, so this error can't be caused by a null data source. Could it be caused by something else, maybe one of the fields in the item template?

Here's the stack trace:
at Telerik.Web.UI.ListViewNullEnumerable.get_DataSourceCount()
at Telerik.Web.UI.RadListView.CreateChildControls(IEnumerable dataSource, Boolean dataBinding)
at Telerik.Web.UI.RadListView.PerformDataBinding(IEnumerable data)
at System.Web.UI.WebControls.DataBoundControl.OnDataSourceViewSelectCallback(IEnumerable data)
at System.Web.UI.DataSourceView.Select(DataSourceSelectArguments arguments, DataSourceViewSelectCallback callback)
at System.Web.UI.WebControls.DataBoundControl.PerformSelect() at Telerik.Web.UI.RadListView.PerformSelect()
at System.Web.UI.WebControls.BaseDataBoundControl.DataBind() at Telerik.Web.UI.RadListView.DataBind()

Here's my HTML code:

<telerik:RadListView ID="RadListView1" runat="server" Width="100%" AllowPaging="true" ItemPlaceholderID="StylesHolder" DataKeyNames="StyleNumber" OnPageIndexChanged="RadListView1_PageIndexChanged">

<LayoutTemplate>

<fieldset style="width: 100%; border: none;" id="FieldSet1">

<asp:Panel ID="StylesHolder" runat="server">

</asp:Panel>

</fieldset>

</LayoutTemplate>

<ItemTemplate>

<div class="grid_3 SearchResults_Container">

<a href="#" onclick="DetailClick('<%# Eval("StyleNumber") %>')">

<%-- This div is necessary in that 'relative' is required in a div before 'absolute' is used in next dic --%>

<div class="SearchResults_ImageContainer">

<%-- This div forces image to be vertical-aligned at bottom, just above text, but centered. --%>

<div class="SearchResults_ImageAlignment">

<%# GetStylePrimaryImage(Eval("StyleNumber") as string) %>

</div>

<%# Eval("StyleNumber") %><br />

<%# Eval("ProductName") %>

</a>

</div>

</ItemTemplate>

</telerik:RadListView>

[Solved] Programmatically Created Chart and Clienttemplate for tooltips

I'm trying to personalize the clienttemplate, formatting numbers, and putting percentage

For a stacked 100% bar chart I have the following:

series.TooltipsAppearance.ClientTemplate = "#= dataItem.categoryName#<br/>#= dataItem.categoryValue#";

It works perfectly, but I want to display only three decimals for categoryValue.

If I try to add kendo.format(...), as I see in some example online, the chart is not shown anymore...

I'd like to show also the percentage of category value (the chart is a stack100 type)

Upgrading from "RadControls for ASP.NET AJAX Q2 2009 SP1"

Hello,

I am working on a project that uses RadControls for "ASP.NET AJAX Q2 2009 SP1" and I would like to upgrade to the latest version of "UI for ASP.NET AJAX" which my company has just purchased.

As the two versions are so far apart can anyone tell me of any pitfalls I may encounter?

Should I just setup a test development environment and "suck it and see"??

Thanks,

Mark.

[Solved] Slider Pager on narrow grid - Page x of Y overwrites Items X to Y of Z

In a fairly narrow RadGrid, PagerStyle is set to Slider, but the slider bar is so wide that when you go to a new page, the Page X of Y label overwrites the Items X to Y of Z label.

How can the width of the slider bar be defined so as to prevent this? I was able to programmatically set it via some JavaScript, but the amount the selector moves per page is off and when you get to Page Y of Y, it still overwrites the Next Page button

The basic issue is in the attached image

RadScheduler overlapping appointments in dayview

Hello,

I've a problem with overlapping appointments. When filtering appointments with three employers, there is no problem. But when I reduce the count to 2 employers, I have empty spaces for the appointment in the display, but three appointments overlap. Shown in the attached pictures.

The Binding is normal - only colours will be set on the event appointment creation event.

The datasource is like (with additional Properties, that doesn't matter here)

Has anyone an idea why the scheduler overlapping these appointments on filtering of appointments of two agents but not on three agents???

Thanks a lot for any ideas.

using multiple dropdownlists within web form user control (ascx)

hello,

i'm testing out 2 controls, the radgrid and the RadComboBox, i'm created a custom edit form using web form user control (ascx) onto which i add labels, textboxes and and dropdownlists, however i'm getting a weird behaviour, this is the expected behaviour:

--- the first dropdown(1) needs to be filled with for example "None,A,B,C,D,E,F,G" while the second dropdown(2) needs to be filled with for example "None,F1,F2,F3,F4,F5,F6"

however what i'm getting is:
--- the first dropdown(1) is filled with "None,F1,F2,F3,F4,F5,F6" and has the correct index while the second dropdown(2) is also filled with "None,F1,F2,F3,F4,F5,F6" and has the correct selected item, which means that the data binding i made to the first dropdown list is overwritten somewhere with the items from the last dropdown created.

if i run the application on debug mode, everything's ok but when the custom edit form opens, all the combos have the exact same items in them, here's my code for creating and adding controls

details.ascx

<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="Details.ascx.vb" Inherits="Project.Details" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<asp:Label ID="LabelLOG" runat="server" Text="Label" Visible="False"></asp:Label>

am i missing some dropdownlist event after binding or setting the selectedindex?
