Asp.net - ItemCommand Fires Before ItemDataBound On PostBack?
Nov 5, 2011
This is just stupid. I've been at this for over 5 hours and can't figure out why my freaking commands aren't firing properly. The only ones that fire properly are the Built-in commands "Edit" & "Cancel"
<asp:ListView ID="NewProduct" runat="server" DataSourceID="NewProductSDS" DataKeyNames="ID">
<ItemTemplate>
<div>
<asp:LinkButton ID="accept" runat="server" CommandName="Accept" />
<asp:LinkButton ID="edit" runat="server" CommandName="Edit" />
[Code]...

A form has many buttons. One of those buttons contains code to update the TableAdapterManager. One of the many TextBox controls has code in a Validating event handler. There is code to make sure a US phone number is formatted properly.If the user tabs out of the TextBox the Validating code works perfectly and show a message to the user if the phone number is not properly formatted and the focus is place in the offending TextBox.If the user clicks on a button that has code to update the TableAdapterManager the Validating code fires but instead of focus remaining on the offending TextBox, the code in the button Click handler also fires.
I would like to stop the button code from firing.Here is the code for the Validating event of the TextBox:
Private Sub TextBoxPrimaryPhone_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBoxPrimaryPhone.Validating
' Make sure the phone is formatted correctly.
[code]....
What additional coding to I need to include so focus remains on the TextBox?

The issue comes when deleteting it will perform itemdatabound twice (but listview prerender once).

I am trying to add an attribute to a tag with ID 'SubNav2' on ItemDataBound which is in the HeaderTemplate of a repeater.ut I keep getting the error: Object reference not set to an instance of an object.Which i think is because it is not finding the object with ID 'SubNav2', am i going about it the correct way?
CODE BEHIND
If e.Item.ItemType = ListItemType.Header Then
Dim ulSubNav2 As HtmlGenericControl = CType(e.Item.FindControl("SubNav2"),

With the ASP.NET Repeater control, I am used to being able to access my data item values in the ItemDataBound Event Handler by doing:e.item.dataitem("column_name")
However, it seems with the ListView control this is not possible. How can I access the data item values?

I am using a combo box on a form in vb net 2008. I would like the user to be able to either tab to the control and then select an
item OR the user could click on the combo box and then select the item.
unfortunately it fires twice when the user clicks on the control. This is before any items are selected. I have tried placing it in mouse down , focus , key down etc etc.
It does not fire twice for the enter event so I tried to use that alone, but then there is no dropping down of the combo box when the user clicks on the control. Is there a way to release the combo box enter event on the mouse click event?

I am trying to create a winform that will allow me to close when the form either loses focus or deavtivate. When I do Me.Show, it will call the deactivate? Is that right or is weird? The way took it was it fires when it either looses focus or is no longer the active form.
Also it seem like I have to click the form in order for it to work right. I tried Me.focus and that does work the way I expected.

I read data into a DS from an XML file. The user has the ability to "Save" or "Save As" at any time. They can also "Open" an existing file or create a "New" one. (brilliant, don't you think?)
I need to make sure I ask the user if they want to save their existing data (i.e. rewrite the XML file) if the DS has changed from the XML load or from the last time they Saved. On Open, New or exit I have been checking the HasChanges function on the DS. This doesn't work the way that I need. I use AcceptChanges throughout the program to commit values to the DS. This appears to kill the HasChanges even though the DS is now different than the XML file.
Is there an event in the DS that fires when data changes? If so, I believe I can set a flag that can be checked later. If not, is there any other way to track that a DS has changed after the initial XML load? Would reloading the XML into a cloned DS and comparing the two work? Seems like a waste of "time", especially with large XML files, but if it's the only way.

In VS2005 I am using click on some elements in a webbrowser document to perform certain functions, eg print or open MS Paint but for some reason all the mouse events fire twice. A second click on the same element might be intentional so I can't just bypass code if the ID is the same as last time. There are no other calls of Document_Click anywhere in the project.[code]I supposes I could stick a timer on it and ignore any within 1s say but cheers for any more elegant solutions.

I have an update statement under RowLeave event of my datagridview. Before I update it I need to validate the cell if there is an empty value. But whenever I moved the focus to another row, RowLeave is called first before CellLeave/CellValidating.Is there another way of validating the cell when leaving a row?
Note: Leaving a cell in the same row is not a problem.

I am trying to unit test for data being input into a textbox (txtPrice). If it is not numeric, it throws a messagebox stating that the input must be numeric. However, when I unit test, I can't figure out why my test fires the message box twice.THis is my (simple) unit test:
Public Sub txtBoxes_LeaveTest()
Dim target As frmEstimate_Accessor = New frmEstimate_Accessor ' TODO: Initialize to an appropriate value
Dim sender As Object = Nothing ' TODO: Initialize to an appropriate value[code].....
My understanding is that for unit testing, you declare the sender, and (in this case) set the sender to some value that will trip the message box. 112L should do this on the leave event. I then write my expected, which in this case is 112L, fire the event, and then get the actual out of the text box. I then Assert.AreEqual to ensure the expected and actual are the same.

I want to move a label across the form every X milliseconds. How do I do that? I understand how to use a timer, but don't know how to move the control. Here is my
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Label1.Location.X = Label1.Location.X + 10
End Sub
"Expression is a value and therefore cannot be the target of an assignment."

I've been trying to get a Timer to execute code every 50ms and it's worked okay, but for some reason after doing the code 8 times (i.e. for 400ms) it just stops. As in, won't execute the code any more times. Specifically, it's wired up to an animation (Picture) and a rectangle which moves around the screen (Box). why the timer would suddenly stop executing after doing so for a while? It's the same duration every time.

My module's Page_Load event is firing twice for each "actual" load. On the initial load both loads' Page.IsPostBack property is false.I've renamed Page_Load to Module_Load to verify the name wasn't an issue. I've made sure the method isn't handling both Me.Load and MyBase.Load, which has been the case in the past.The only thing I'm doing out of the ordinary is that my module is inheriting from an intermediate base class. Could this be the culprit? [code]I had an Image without an ImageUrl. Presumably this is set by my CollapsiblePanelExtender but rendered with a blank src.

I have a VB .NET form with a splitter control on it, and I want to save its position between program runs. I am currently handling the SplitterMoved event and storing the SplitterDistance. Then on program startup, I set the SplitterDistance to the saved value.
However, sometimes the program resizes the splitter, raising the SplitterMoved event and overwriting my saved distance. I have several splitters over multiple tabs in a tab control, and any time the user goes to a new tab for the first time, the SplitterMoved event fires.Is there an event I can use that will only fire when the user moves the splitter, and not when the program moves the splitter? I tried MouseUp, but when that event fires, the new SplitterDistance is not yet set.
