Hi,
I'm debugging my code and when it reaches a certain point this
messages pops up: "There is no source code available for the current
location." I had this problem before but it was in a different
scenario and I don't remember how it was solved.
I really don't understand this problem and why it happens. This is the
situation:
- I have a DataList with ImageButtons that pop up an image in a bigger
size using the ModalPopupExtender, from the Ajax Toolkit.
- The DataList is inside an UpdatePanel.
- The user of the page can visualize the DataList, add more images to
the DataList and Delete the Datalist. The routine for binding the
DataList is called in 3 cases: when the user wants to view the images
in a gallery of images, after the user add an image to the gallery and
after the user deletes an image in the gallery. In the first two cases
(to view the gallery and after adding an image), the routine works
exactly how it's suppose to work and there's is no problem. However,
after the user deletes an image the error message pops up when the
debugger is going from the line myDataList.DataSource = dTable to the
line myDataList.DataBind()
Here is my code for binding the DataList:
Private Sub BindmyDataList(ByVal theID As Integer)
Dim dTable As DataTable = GetImages(theID)
GalleryIDHiddenField.Value = theID
myDataList.Visible = True
If dTable.Rows.Count = 0 Then
DataListMessageLabel.Visible = True
DataListMessageLabel.Text = "There are no images to be
displayed."
DataListMessageLabel.CssClass = "error_message"
Else
DataListMessageLabel.Visible = False
End If
myDataList.DataSource = dTable
myDataList.DataBind()
DataListDiv.Visible = True
End Sub
Does anyone knows why this message is displayed, what is the problem
and how to solve it? I appreciate your help!
Ana
