I have an asp drowndownlist and I'd like to change its selection after a button click. I can't seem to find a way to do this, is there a way? (Its a reset button of sorts, and I would like the dropdownlist to return to the "default" value.)
View 2 RepliesI have to hidden buttons on my page that I can trigger using JavaScript (__dopostback...). I also have a list of object on my page and a dropdownlist giving the user the possibility to sort those objects on the page. My code checks the current value of the dropdownlist on Databind of the list and applies the chosen sort method to the list. The first button is triggered when the user has selected another sort method from the list.
The second button is triggered when the user adds a new item to the list. Sortmethod "sort2" should be set automatically in the dropdownlist if this happens. So when the second button has been clicked, I need to set the selected item of the dropdownlist dynamically so I can check the value of the selected value later in the DataBind method of the dropdownlist and know what sort method should be applied.
I don't succeed in changing the selected value dynamically. I'm using to controls: First is the objects.vb and the second is the ObjectContainer.vb. Objects.vb contains the two buttons, the dropdownlist and an instance of the objectcontainer. The objectcontainer contains the list with objects that needs to be sorted based on the value selected in the objects control.
Objects.vb:
Private sortMethod As DropdownList
Private container as ObjectContainer
Protected Overrides Sub OnInit(ByVal e As System.EventArgs)
MyBase.OnInit(e)
EnsureChildControls()
End Sub

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.

Const dcmPRICE_STRESS As Decimal = CDec(595.0)

View 3 RepliesI've got a right-click menu that comes up in a treeview - with an option to ADD to that parent node or delete a child node.
Currently I'm using the SELECTEDNODE - but what I really want to do is change the "selected node" when the right-click occurs. But I'm having a hard time seeing how to do that...
How do you use this event properly??
Private Sub CapabilitiesTreeView_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles CapabilitiesTreeView.MouseClick

I made my listview, and it's delete and edit events are working properly, now I want to implement a possibility for user to mark an element as "default". D, E and Def are buttons
Reference
----------------------------------------------------------------
- ref1 - somevalue - somevalue - somevalue - [D] - [E] - [Def]
----------------------------------------------------------------
so that would be a row from a table, I made delete and edit work by handling events from listview,
Private Sub lvMain_ItemDelete(ByVal sender As Object, ByVal e As ListViewDeleteEventArgs) Handles lvMain.ItemDeleting
Dim refFac As new ReferenceFactory
refFac.Delete(e.Keys(0))
EndSub
similar for Editing. But now when I try to get values from Default button, the button wont even do anything...This is the code:
<asp:ImageButton ID="ibtDefault" runat="server" ImageUrl="~/Images/Default16.png" CommandName="Default" />
and for my logic:
Public Sub ibtDefault_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs )
SelectedRef.Name = "Test"
End Sub
I just wanted to test it whether it will run or not by changing the value of my global string that will show which Reference is made default. But it wont even do that...Then I tried with Commands.
Private Sub lvMain_ItemCommand(ByVal sender As Object, ByVal e As ListViewCommandEventArgs) Handles lvMain.ItemCommand
If e.CommandName = "Default" Then
'Dim refID As New Integer

I have a VB.NET form which was generated when I dropped some fields from a data source table onto a form. To add new records using this form you click on a '+' on the toolbar at the top of the form. What I would like to do is make it so this form functions as if the button had been clicked automatically when it is opened. How do I invoke the add new item ('+') function on a form before the user sees it? When you click on the + a -1 appears in the id field which is on the form but I can't figure out how to cause this with code.

I have a listbox that when you click on the item it displays a picture in a picture box and a message in a label. It works fine when an item is manually selected, but I want forward and back buttons that will do this. It works once but it doesn't highlight the new item in the listbox, so it gets stuck. I can't use a loop either.

I am currently trying to develop a program where you click on a datagridview row and then at the bottom of the window there is a button called "Modify."Once you hit this button, another window will pop open to where the user can modify the information on that specific datagridview object.I want the program to fill in what has already been entered so the user can go back and make changes if need be.I understand that datagridview has it's own update commands, but when I created by table adapters and everything, it did not create them.I am not sure if there is a way to create the update command manually, but this is the best way to explain it.

I have this code in the click event for a button I want to be able to select a row in my datagridview then Hit the ok button and have it populate to text box1 if textbox1 is already filled then i want to go to textbox2 and so on, (total of 6) So far if extbox1 is empty "" and i click ok button it populates, when i click ok button again to textbox2 does not populate.
I have 13 variables, all called Items1, Items2, Items3 and so on. I have a combo box with items in, each time I click a button I want it so whatever is selected is stored in a variable and if the button is selected again then it stores whatever is selected in the next variable. I know all the code for selecting items in a combo box and transferring it to a variable but the problem I cannot do is the part where each time a button is clicked it stores whatever is selected in the combo box to the next variable.

View 2 RepliesI have to create a program where you enter the description, price, and quantity of an item, then click on the Add button. It will then put the description, price, quantity, and total for that line (including tax) in a listbox. The tax is determined by what you put in a text box labeled tax:. When you press Submit Order, it should show a grand total in a text box called Grand Total. It should have a class that is called Items that has a function called GetTotalAmount() that figures out the total including tax. I have started it, but am having a tough time with how to get the subtotals into the text box, then also show the amount including the tax PLUS then do the grand total.

I am using ASP.NET with VB.NET as background code. I have 8 ImageMaps in my webform Estimator.aspx.Each ImageMap represents a car part (Front Bumper, Rear Bumper, Mirror, Hood, Sunroof, DoorShell, Headlights, Tail lights) and I have a dropdownlist ddlChosenParts. When the user clicks on any of the 8 ImageMaps, I add the PostBackValue to the dropdownlist ddlChosenParts.The problem is that if the user clicks on the same ImageMap twice, the PostBackValue is added twice.I want to check if ddlChosenParts contains the ImageMap's PostBackValue and if it already contains it, do not add it again. That means that if the user clicks more than once on the same ImageMap, it's PostBackValue is only added once in ddlChosenParts.I have this code but i'm getting an error: Value of Type String cannot be converted to ListItem.

View 4 RepliesI have created a dropdownlist which I choose wizard way to fill data in it. and its property like:
DataTextField=Item
DataValueField=ItemCode
I go to properties of this dropdownlist and then I add Items property as the following:
Enabled=true
Selected=false
Text=---choose---
Value=-1
And the code behind is that:
dim strItem as string= ddlItem.selectedItems.text
if ddlItem.selectedItems.text.trim="---choose---" then
Label1. text=" You haven't choosen any items yet!"
exit sub
else
Label1. text=" You have choose"
end if
But when I start debugging this:
strItem always gets "---choose---" text eventhough I choosed other items.
I would like to set the selected item in the combo box. It is working, If the dropdownstyle is dropdownlist. But not working, If the dropdownstyle is dropdown. How to make it work when the style is dropdown?
