In case this helps someone else: I was having difficulty with my column RadHTMLChart. There were no exceptions but it wouldn't display the data. I was binding to a dataview and setting the DataFieldY and DataLabelsField to columns in that dataview. Long story short, it seems that there are certain reserved words that the chart has trouble with. In my case, my dataview had a column named "count" and a column named "Category". I changed my SQL query to give the column names the aliases of "ErrCount" and "CategoryName", changed the chart's DataFieldY and DataLabelsField properties to use these new column names, and then the chart displayed correctly.

While I have solved my problem, I'm wondering if there is documentation which lists reserved keywords so I don't run into this again?

Why is this style setting not working

I have an aspx page with a master page and a css file set on the master page. In my Rad grid I set the Heder Style to this

<HeaderStyle CssClass="Myheader" /> and in my .css file I added the following class:

.Myheader
{
background-color:red !important
}

My Header still has a black background color

Can anyone see a problem here?

RadComboBox CheckedItems is always zero

I have a RadCombBox and RadButton like this:

<telerik:RadButton runat="server" id="btnPlantName" OnClick="btnPlantName_Click" Text="Filter"/><br />

<label for="" class="filterElement">Plant Name: </label>

<telerik:RadComboBox

ID="RadComboBoxPlantName"

DataSourceID="SqlPlantNameList"

DataTextField="PlantName"

DataValueField="PlantName"

AppendDataBoundItems="true"

runat="server"

OnClientSelectedIndexChanged="PlantIndexChanged"

class="filterElement" EnableLoadOnDemand="false"

CheckBoxes="true" EnableCheckAllItemsCheckBox="true">

</telerik:RadComboBox>

And my code behind is set up like this:

protected void btnPlantName_Click(object sender, EventArgs e)

{

FilterByComboBox(RadComboBoxPlantName, "PlantName");

}

private void FilterByComboBox(RadComboBox box, string columnName)

{

var selectedItems = box.CheckedItems;

List<string> values = new List<string>();

if (selectedItems.Count != 0)

{

foreach (var item in selectedItems)

values.Add(item.Text);

FilterColumnByMultipleValues(columnName, values.ToArray());

}

When I step through the code, the event is fired properly, but box.CheckItems is always zero. Why is this? I need to be able to get all the values.

Thanks!

[Solved] RadGrid in HeaderTemplate- client side binding gives blank values

hi,

I have a radpanelbar on our page, on one of the panels we have radgrid with client side databinding in HeaderTemplate of a panelitem. The grid has GridboundColumns. When data is bound, the grid shows empty values for all columns of all rows.However if I move the grid to content template of panelitem then there is no such issue.

What is causing this problem? Is there anyway we can resolve this issue?

Regards,

Kiran

RadListBox and SelectedItems

Hi,

I am using a RadListBox and I would like to find if the items that are selected in this list when clicking on a search button. However, when doing the following I have no item selected (the Label text is = 0) and I do not see why?

In my Search.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Search.ascx.cs" Inherits="Controls.Search.Search" %>

<telerik:RadListBox ID="List1" runat="server" SelectionMode="Multiple" CssClass="rListBx"/>

In my Search.ascx.cs:

Label.Text = List1.SelectedItems.Count().ToString();

My Search_Click function is in a partial class that inherits from System.Web.UI.UserControl

In my Search.ascx.designer.cs

protected global::Telerik.Web.UI.RadListBox List1;

An idea about what I am doing wrong here?

Thanks

ListBox
