Hi All,

How can i get filtering my RadGrid with text? For Example in the slider 7 different Colour.
a  b  c  d  e  f  g 
and in the default view table will show products all of this colours
when user draging slider from a to b
i want to showing products which coloured b c d e f g in my RadGrid

When it is all numbers in DB it is ok. No Problem but when i wanted filtering with text really confused.

Hope to hear you soon.




telerik:RadSlider runat="server" ID="RadSlider1" IsSelectionRangeEnabled="true"




MinimumValue="0" MaximumValue="300" SmallChange="1" SelectionStart="0" SelectionEnd="300"




OnClientValueChanging="OnClientValueChanging" OnValueChanged="RadSlider1_ValueChanged"




OnClientSlideStart="OnClientSlideStart" OnClientSlideEnd="OnClientSlideEnd" AutoPostBack="true"




ShowDecreaseHandle="false" ShowIncreaseHandle="false" />


SelectionStart: $


<asp:Label ID="lblSelectionStart" runat="server" Text="0"></asp:Label><br />


SelectionEnd: $


<asp:Label ID="lblSelectionEnd" runat="server" Text="300"></asp:Label>




Protected Sub RadSlider1_ValueChanged(ByVal sender As Object, ByVal e As EventArgs)


lblSelectionStart.Text = RadSlider1.SelectionStart.ToString()

lblSelectionEnd.Text = RadSlider1.SelectionEnd.ToString()




End Sub





="SELECT * FROM [Products] INNER JOIN [Suppliers] ON Products.SupplierID=Suppliers.SupplierID WHERE (UnitPrice &gt; @MinimumPrice) AND (UnitPrice &lt; @MaximumPrice) AND (UnitsInStock &gt; @MinimumStock) AND (UnitsInStock &lt; @MaximumStock) AND (CategoryID &gt; @MinimumCategory) AND (CategoryID &lt; @MaximumCategory)">








<asp:ControlParameter ControlID="RadSlider1" PropertyName="SelectionStart" Name="MinimumPrice" />

Hi Omer,
I am not quite sure I understand you question correctly. In case you are not sure how to construct your select statement using a parameter with text value, I believe the following MSDN article will help you get started -

On the other hand, in case you are not sure how to display text with RadSlider, please refer to our online demos - Please note that in this case you will not be able to use a control parameter because the Value and Text properties of the selected items are not exposed as properties of the slider control. You can use the base parameter class instead and set its DefaultValue property dynamically. You can use the SelectedItems property of the slider to access the selected items and their Values.

Best wishes,
the Telerik team
