Hi,
I would like to know, when I click a button, whcih other events are called before button click event is called.
thank you,

You can write a small program which subscribes to button events and shows an event on the screen

Are you talking about Windows Form or Web Form ?

I cannot figure this out! It is driving me nuts!
Ok so I can do a IndexOfKey and get the index (which in my case is 24), but when I try to get the text it gives an error:
int index = 0;
index = lstImport.Columns.IndexOfKey("Category");
MessageBox.Show(index.ToString());
if (index == -1) cmd.Parameters.AddWithValue("@Category", "");
else cmd.Parameters.AddWithValue("@Category", lstImport.Items[i].SubItems[index].Text);
ERROR:
System.ArgumentOutOfRangeException was unhandled

And your row really has 25 columns in it ?

I actually did a lstImport.Columns.Count right after showing the MessageBox that gives 24 and the count comes to 29.
I'm taking data from an excel sheet and trying to import it into the database.
|
|
|
|
|
Ok I did this:
index = lstImport.Columns.IndexOfKey("Category");
MessageBox.Show(index.ToString());
MessageBox.Show(lstImport.Columns.Count.ToString());
MessageBox.Show(lstImport.Items[i].SubItems.Count.ToString());
So the subitems only have 23, the columns is 29, and the index of category is 24. Now if I add this Category column AFTER importing the excel sheet into the listview does the item's not add those columns to the subitems? The values are blank.. but they should still see the new columsn right but just have no value?

I just went to a Datagridview.. thanks
|
|
|
|
|
And I bet there are some blank columns on the right of your data which probably failed when loading into the listview because they are null
|
|
|
|

Well what I did is loaded the list view with data from the excel sheet, and then looked to see if that excel sheet was missing certain columns. If it WAS missing the columns (I.E. not in the list view columns after being loaded), then I would add them at runtime. Like you mention, the problem was is that the ITEMS were added to the list view before adding the new columns. So the ListView itself sees the columns but the items in it don't. I guess I could of stored that information somewhere else that the columns were missing and at import added blank values to those sql parameters for the ones missing. Problem with that is when the user looks at it, the columns are still missing.
So the listview had the correct amount of columns, but the items didn't. Strange, I figured after adding the columns to the listview it would of appended the columns to the end of the items. To fix it I bet I could of looped through each item and added blank subitems to each one of them after adding each column..
But I ended up using a datagridview instead and I was able to make all that work.

There are only 23 SubItems in the collection (indexed 1 to 23) and you are trying to access index 24, which is causing this error. Try using index-1 instead. I believe IndexOfKey takes into account the first column also (which is not included in the SubItems collection).
|
|
|
|
|
Yes.. the problem was that the items only had 23 subitems, but the listview had 29 columns since the columsn were added after the items. I would of figured adding columns would of appended it to each item. I posted more of an explanation above ^^^
Thanks!

In ListView, everything except the first column is in SubItems collection. You cannot have anything "after" that. So, if your ListView really has 29 columns, it should have 28 subitems, and conversely, if there are only 23 subitems, it means the ListView has only 24 columns.

MyForm.Enabled = false?
Or if you're in WPF, IsEnabled = false
|
|
|
|
|
How will you enable it again ?
|
|
|
|
|
Iterate the members of Controls and disable each?
|
|
|
|
|
Generally (depending on what you want it to look like) I'd stick the controls on a panel (or similar) control and then enable/disable the panel.

Put all the controls (that need to be disabled) on a panel and disable the panel.
