I've come across an error I'm not quite sure how to get rid of, I've got a listview with listview items making up the grid, I've got values coming from a database populating the cells however if there are any null values(in this case, there's null values in the date) it crashes my program. I'm not quite sure of a way to allow the listview to have null values in it, I figured it would default allow it but that's not the case.[code]....

View 1 Repliesi have a listview in form1 and combobox in form2..i want add every first item of listview of form1 into combobox of secondform....i did this...

I have a child form which contains a list of names and information, like age, sex, etc, in a multicolumn listview that gets populated from an xml file on the form load.There is also a combobox on this form that contains different Ages and when the user selects an age in the combobox I have it so the listview clears and the data reloads then removes all the rows that don't contain the matching "age" value in the age column.This works but it's really slow since each time a user makes another choice from the Combobox the whole listview is repopulated from the xml file.[code]I was thinking about doing the Name filter about the same way except on the textbox keyup event, but I fiqured I'd work at getting this working better first since this is way too slow.I don't really know any way of filtering the listview other than deleting the entries that don't match what's in the combobox.But then I end up reloading the whole thing when another selection is made from the combobox.

View 4 RepliesI want to setup values for a combobox in vb.net through code. But I don't know what's the code for setting it up. I want to do something like this:
if combobox1.selecteditem="1" then
combobox2.values=("x", "y", "z")
end if
I display some values in a combobox that come from an array.By default the selected index of the combobox should be the first item.
If cboAtt.Items.Count = 0 Then
For i = 0 To nums(att)
cboAtt.Items.Add(cat(att)(i))
Next
[code]....
This works perfectly, but now I want the combobox to display the new (initial) value that is swapped, except than when I do that the cboAtt_SelectedIndexChanged event is triggered which results to an infinite loop --> crash.

i want to add values in reversed order in combobox2 that are available in combobox1
but when i run the application the second combobox remains empty and not showing any value.
When I update but do not really made any changes to the value and press the update button, the data becomes null. And it will seem that I deleted the value.I've taught of a solution, that is to add both combobox1.selectedtext and combobox1.selecteditem to the function. But it doesn't work.
combobox1.selecteditem is working when you try to alter the values when you update. But will save a null value when you don't alter the values using the combobox combobox1.selectedtext will save the data into the database even without altering.But will not save the data if you try to alter it.-And I incorporated both of them, but still only one is performing, and I think it is the one that I added first:
Dim shikai As New Updater
Try
shikai.id = TextBox1.Text
shikai.fname = TextBox2.Text
shikai.mi = TextBox3.Text

Let's say I have 50 cars and I created 6 attributes for each of the 50 cars (therefore 300 total variables and values for those 300 variables). These attributes are created and valued based upon the following structure:
Car1Name = "Dark Red Car"
Car1Color = "Dark Red"
Car1DoorCount = 4
Car1Cost = 10000
Car1Appeal = 10
Car1BoughtStatus = False
Car2Name = "Bright Red Car"
Car2Color = "Bright Red"
Car2DoorCount = 4
Car2Cost = 11000
Car2Appeal = 8
Car2BoughtStatus = True
and 48 others of similar structure/syntax
How do I take a a module with these variables and values and populate them into a listview within a form such as Form1 and ListView1 without continuously going into listview's UI and manually entering the data? The goal is to show the USER a list of 50 cars, their color, door count, cost, appeal, and purchase status.
i have some problem with the listview control i dont know how to use it
