Hello all,

I am using ComboBox with multi check box and Filter option. I would like to know how can I get text which i gave in input area (for filtering) in code behind.

For example, if i have a combobox which shows all the countries -> typed "Ge" input area. Then menu/option in the dropdown with filter accordingly.

Now my requirment is How will i get the string "Ge" in code behind (in any event) and i prefer to do this code behind rather JS.

I hope this makes sense and looking forward for its solution...

Thankz

Scatter marker size based on count in datasource?

Hello Stamo and others,

Is it possible to bind the marker size to a value like a count within the data source? Or will we have to programmatically create the ScatterSeriesItem and set the marker size within code? Or can we databind the scatter series items then iterate over the items (after binding) and set the marker size for each item in code?

Thanks in advance,

Filter radgrid based on datepicker

Hi Telerik team,

I am trying to filter date column on my radgrid by the following RadDatePicker:

<label>Start Date:</label>
        </div>
                                        <telerik:RadDatePicker ID="RadDatePicker1" Runat="server" AutoPostBack="True" Culture="en-ZA" MinDate="2015-01-01" SelectedDate="2015-01-01" Skin="BlackMetroTouch">

            </div>

                            <telerik:RadDatePicker ID="RadDatePicker2" Runat="server" AutoPostBack="True" Culture="en-ZA" MinDate="2015-01-01" SelectedDate="2015-01-01" Skin="BlackMetroTouch">

[Solved] RibbonBar use SplitButton in Menu

If I use a SplitButton inside of a Menu when creating my xml to load in to the ASP.NET RibbonBar, it does not place the SplitButton buttons in any kind of dropdown. It places them at the same level of Menu. Here is the XML:

<?xml version="1.0"?>
<RibbonBar>
<ApplicationMenu Text="Home">
<ApplicationMenuItem Text="Item1" />
</ApplicationMenu>
<Tab Text="Tab1" Size="Small" ImageUrl="/Images/Image1.png">
<Group Text="Group1">
<Button Text="Button1" Size="Large" ImageUrl="/Images/Image2.png" />
<Menu Text="A Menu" Size="Medium" ImageUrl="/Images/Image3.png">
<MenuItem Text="MenuItem1" Size="Large" ImageUrl="/Images/Image4.png"></MenuItem>
<SplitButton Text="SplitButton" Size="Large" ImageUrl="/Images/Image5.png" ImageUrlLarge="/Images/Image5.png">
<Button Text="SplitButton_Button1" Size="Medium" ImageUrl="/Images/Image6.png" />
</SplitButton>
</Menu>

Drilldown chart: how to get non-charted data

With RadGrid I frequently use a SQL data source which returns data columns with "display=false" so that I can use a value for inclusion in a templated column. Typically this is for purposes of building a hyperlink with a client-friendly display value, but with a database code for the querystring.

"<a href='whatever.aspx?id=category_code>category_name</a>

When using HTML Pie Chart, I know how to retrieve the values of "DataFieldY" and "Name_Field".

The "NameField" is my "category_name" but when clicked, I really want "category_code", i.e. a value known to the underlying data source but not displayed on the chart itself.

Any suggestions on a potential solution?

Note that I could do I reverse lookup back into the database, but there are cases where we trim long "Name_Field" values to avoid messing up chart presentation.

Telerik UI ASP.net RADGRID set Columns width programmatically

Hi

I am trying to display a Telerik RadGrid in my project.
I have a problem with changing the column width.
The data source of my grid is a list of objects.
When I add filters to the grid, the columns' width is fixed and I cannot change it / resize it.

P.S. I want to solve this programmatically(in vb code)

my vb code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not IsPostBack Then

setColumnsOnGrid(Of object)(lst, RadGrid1, ArrayNameFilds:={"column1", "column2", "column3 ", "etc."})

End If

End Sub

Private Sub setColumnsOnGrid(Of T)(ByVal lst As List(Of T), ByVal grdName As RadGrid, ByVal ArrayNameFilds As Array)

Dim nameFiled As String

grdName.DataSource = lst

grdName.AllowMultiRowSelection = True

grdName.MasterTableView.AutoGenerateColumns = False

Dim boundColumn As GridBoundColumn

For i As Integer = 0 To ArrayNameFilds.Length - 1

nameFiled = ArrayNameFilds(i).ToString()

boundColumn = New GridBoundColumn()

grdName.MasterTableView.Columns.Add(boundColumn)

boundColumn.DataField = nameFiled

boundColumn.HeaderText = nameFiled

Next

End Sub

my aspx:

<telerik:RadGrid ID="grd_test" runat="server" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" CellSpacing="0" GridLines="None">

<ClientSettings>

<Scrolling AllowScroll="True" UseStaticHeaders="True" />

</ClientSettings>

</telerik:RadGrid>

[Solved] HyperLinkColumn : URL lost with PageMethods

Hello,

Below is some code to demonstrate my problem :

I use a grid with 3 pages, each containing only one row for simplicity.. The grid contains an hyperlink column (another is visible here only for verification).

The first page is displayed by default and then we can observe a correct URL to the passage of the mouse over it.
Changing page calls PageMethods to get data client side, and oddly the url is lost... However, verification column displays the correct URL.

Thank you in advance for your help.
