Re: ComboBox (ComboBoxStyle.Simple) Without Showing the List

Alternatively of course, if I can just hide the drop down button, I can stifle the drop down behaviour.

So, I'm either looking to hide the list portion in ComboBoxStyle.Simple mode, or hiding the dropdown button...

How about:

if (! zEnabled)
    comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
else comboBox1.DropDownStyle = ComboBoxStyle.Simple;

Hi, thanks for the reply.

That's pretty much what it's doing at the moment. The problem is that in 'Simple' mode, the list is displayed as a box below the selection box permanently. It's this bit that I wish to remove, so that the combobox appears like a normal text box.

Hmmmm. In my test it doesn't show the list at all. It just appears like a TextBox but lets you scroll through the list items with the arrow keys. Did you perhaps set a size parameter or number of items to show?

I simply grabbed a ComboBox and put it on a Form, added a few items, and made a button that changed modes as above to test the behavior.

Interesting... it does appear to behave itself throughout the program with a pre-designed ComboBox.

However, if I dynamically create a custom ComboBox in code, and change the ComboBoxStyle, the list will not disappear. I've tried adjusting the size of the box but this has no effect, they always appear with an ugly big box underneath.

Why would it do this only for dynamically created ComboBoxes?

Thanks for looking at this with me, it's much appreciated.

My guess, based on experience, is that there's probably some default parameter in the pre-designed and dynamically created controls that is different, but I have no idea which one.

I've run into that problem with other controls before and tracking down the parameter was tedious. Perhaps you could put a pre-designed control on a form, then add a second one dynamically, then stick in a break point and examine all the parameters one by one to see where the difference is.

Changing DataGridView selection

15-Jun-09 22:17

I'm getting the impression that when the component is initially drawn in simple mode it is drawing to a default size - I'm getting around it at the moment with a 'bodge' where I'm explicitly resizing the boxes after they have been drawn - not idea, but it acheives the result.

If I get some I'm going to examine the parameters as you suggested.

Thanks for all the suggestions and help.

This is a bit of an odd question, but can I select a new row in a dgv and clear the old selection as an atomic operation? I can do it in two statements but that results in the SelectionChangedEvent firing twice.

dgv.ClearSelection();
dgv.Rows[e.RowIndex].Selected = true;

I don't believe that you can.
It is possible to override SetSelectedRowCore where you could put the ClearSelection, but that would, to all intents, be the same as having MultiSelect = false

Hardly useless. There you will find poeple who will be only too happy to work for you.

Of course, they will want paying...or had you noticed that?

It's the most useful reply you will get, trust me.

Either go to rentacoder, or give your client back his money and let someone willing to do research or someone with prior knowledge benefit from their talent. Not a hack like you trying to get free code to profit off of it.

what is the problem with u , i don't know i think you may be a frustrated coder who are not getting projects from retacoder and for your kind information this not of any client project but it is a project which is asked by my boss, he wants me to develop an addin in outlook which allows him to send multiples message to clients , but not using bcc or cc.one client should get one message and their mail id should be in To:.

I think it is enough for you to understand , dont make this forum ugly for the first time in 2 years i got reply like i too have given critical codes to many fellow members but i didn't ask them blah blah blah.

I'm not registered on rentacoder, or I might be, but I have never used the site itself. It's where I redirect tools such as yourself to get work done without trying to rip someone elses work and pass it off as your own, as you admitted to doing here ...

I am just asking has any one done that before bcoz i googled alot and i didn't came up with an answer,

<blockquote class="FQ"><div class="FQA">EliottA wrote:</div>... and to that effect you should get fired. </blockquote>

Why would i, did you know all the answers of c# are you a master or architect of c# who knew every thing or u r genius by birth.I dont know
my boss always happy on my work and i gave him job done in deadline .
Did you not google if you don't know the answers, did u not turned down to codeproject like forums to know your answer.

I don't realy understand your attitude: a quick Google gave me two different solutions to your problem. Ok, not in C#, but .NET is .NET is .NET so it would be transferable.

If you didn't "get pissy" as EliottA says, I might have expanded on this, but Hey! I can't be bothered!
