i want to create a very simple filter in the headercontextmenu of a radgrid.
The filter should consist of one textbox.

Can you explain me, how i can realize this?

I've attached two files (screenshots).
FilterIst.jpg = this is the filter in my current grid.
FilterSoll.jpg = this is the filter, i want to have.

Prevent delete for 1 row

I'm using a radgrid with a gridbuttoncolumn as the last column in the grid. It has a delete command.

How would I prevent the button from appearing for a single row? The data is sorted by PK "id" field. It's the first item in the grid (id=1) that I do not want anyone to delete. Is there any way to hide the delete button for this particular row? Thanks.

RadGrid radio button

I have a very simple Grid with a template field containing a radio button:

<telerik:RadGrid ID="rg_VehicleImages" runat="server"

AllowAutomaticDeletes="True" AutoGenerateDeleteColumn="True" CssClass="radgrid"

DataSourceID="sds_ImagesVehicle" GridLines="None" Width="220px">

<mastertableview autogeneratecolumns="False" datakeynames="IDImages"

datasourceid="sds_ImagesVehicle">

<rowindicatorcolumn>

<HeaderStyle Width="20px" />

</rowindicatorcolumn>

<expandcollapsecolumn>

<HeaderStyle Width="20px" />

</expandcollapsecolumn>

<Columns>

<telerik:GridBoundColumn DataField="IDimages" DefaultInsertValue=""

HeaderText="" ItemStyle-ForeColor="White" ItemStyle-Width="2px"

SortExpression="True" Visible="True">

<HeaderStyle Width="2px" />

<ItemStyle ForeColor="White" Width="2px" />

</telerik:GridBoundColumn>

<telerik:GridImageColumn AlternateText="Thumbnail"

DataImageUrlFields="FilePath, ThumbnailName" DataImageUrlFormatString="{0}/{1}"

DataType="System.String" FooterText="ImageColumn footer" HeaderText=""

ImageAlign="Middle" UniqueName="vehicleimage">

<HeaderStyle Width="75px" />

</telerik:GridImageColumn>

<telerik:GridBoundColumn DataField="ThumbnailName" DefaultInsertValue=""

HeaderText="ThumbnailName" SortExpression="ThumbnailName"

UniqueName="ThumbnailName" Visible="False">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn DefaultInsertValue="" UniqueName="rbt_VehicleImage">

<ItemTemplate>

<asp:RadioButton ID="rbt_VehicleImage" GroupName="MyGroup"

onclick="MyClick(this,event)" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</mastertableview>

<clientsettings>

<clientevents onrowdblclick="RowClick" />

</clientsettings>

</telerik:RadGrid>

The grid displays images of a vehicle selected from a database on the key field IDVehicle where tbl_Images.IDVehicle = tbl_Vehicles.IDVehicle

There may be many images for the vehicle so I need to be able to allow the user to select one image as the 'default' or main image to use on reports. To do this I thought it would be simple to add a radio button to the grid so that when the user selectes the radio button the database would be updated so that the DefaultImage field (SQLDataType = BIT) would be set to True for the selected radio button and all of the other buttons with the same IDVehicle would be set to False. Something like:

Protected Sub rg_VehicleImages_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rg_VehicleImages.ItemDataBound

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim RadioBtn As RadioButton = DirectCast(item.FindControl("rbt_VehicleImage"), RadioButton)

If RadioBtn.Checked = False Then

Dim sql As String

Dim strConnString As [String] = System.Configuration.ConfigurationManager.ConnectionStrings("CF_SQL_Connection").ConnectionString()

sql = "UPDATE CF_Images SET DefaultImage = @Value WHERE IDImages = @IDImages"

Dim connection As New SqlConnection(strConnString)

Dim command As New SqlCommand(sql, connection)

Dim IDImages As Int32 = DirectCast(item.GetDataKeyValue("IDImages"), Int32)

command.Parameters.Add("@IDImages", SqlDbType.Int).Value = IDImages

command.Parameters.Add("@Value", SqlDbType.Int).Value = "0"

command.Connection.Open()

command.ExecuteNonQuery()

command.Connection.Close()

Else

Dim sql As String

Dim strConnString As [String] = System.Configuration.ConfigurationManager.ConnectionStrings("CF_SQL_Connection").ConnectionString()

sql = "UPDATE CF_Images SET DefaultImage = @Value WHERE IDVehicles = @IDVehicles AND IDImages = @IDImages"

Dim connection As New SqlConnection(strConnString)

Dim command As New SqlCommand(sql, connection)

Dim IDImages As Int32 = DirectCast(item.GetDataKeyValue("IDImages"), Int32)

Dim IDVehicles As String = Request.QueryString("IDVehicles")

command.Parameters.Add("@IDVehicles", SqlDbType.Int).Value = IDVehicles

command.Parameters.Add("@IDImages", SqlDbType.Int).Value = IDImages

command.Parameters.Add("@Value", SqlDbType.Int).Value = "1"

command.Connection.Open()

command.ExecuteNonQuery()

command.Connection.Close()

End If

End Sub

Of course this does not work. I am not sure if it is because I am attempting this using the Grid ItemDataBound argument and not one associated with the radio button.

Any help much appreciated.
