Get RadComboBox Attribute in RadGrid

[Ajay]

Hi

I have a RadComboBox in RadGrid.

How do I get the Attribute of the RadCombo box. I have tired the following code but I get an error :

    Protected Sub rcbPortList_Grid_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

 

        Dim rcbPortList_Grid As RadComboBox = New RadComboBox

        rcbPortList_Grid = DirectCast(sender, RadComboBox)

 

        Dim EditedItem As GridDataItem = DirectCast(rcbPortList_Grid.NamingContainer, GridDataItem)

        Dim gvddlEmployee As RadComboBox = DirectCast(EditedItem.FindControl("rcbPortList_Grid "), RadComboBox)

 

        Dim rtxtLongDegree_Grid As RadNumericTextBox = DirectCast(EditedItem.FindControl("rtxtLongDegree_Grid"), RadNumericTextBox)

        Dim rtxtLongMin_Grid As RadNumericTextBox = DirectCast(EditedItem.FindControl("rtxtLongMin_Grid "), RadNumericTextBox)

        Dim rtxtLongSec_Grid As RadNumericTextBox = DirectCast(EditedItem.FindControl("rtxtLongSec_Grid "), RadNumericTextBox)

 ' Object reference not set to an instance of an object. error at line below

        rtxtLongDegree_Grid.Text = rcbPortList_Grid.SelectedItem.Attributes(0)("Longitude")

 

end if

Hi Ajay,

At which line are you getting an error and what is it?

Two things that I notice:
1) This code will work only for InPlace edit mode. If you use EditForms or PopUp edit mode, you need to cast the combo's naming container to GridEditableItem/GridEditFormItem.
2) You index the Attributes both by numeric index and by key. You should only use a key in order to access an Attribute of a control, e.g. combo.SelectedItem.Attributes("onclick"). Also, I assume that Longitude is an attribute which you have assigned in a previos event?

Kind regards,

I am getting the error at:

rtxtLongDegree_Grid.Text = rcbPortList_Grid.SelectedItem.Attributes(0)("Longitude")

I am using Inline Edit and yes the attribute "Longitude" is added before hand..

Hi Ajay,

Have you tried accessing the Attribute only by key:
string attribute = combo.SelectedItem.Attributes("Longitude")

I am not sure exactly what indexing is done using the numeric indexer.

All the best,
