View 3 RepliesI do have a form with a ToolStrip and some other controls on it. I use this form in other projects as kind of base form, which means that the other forms inherit from this form.
My problem: In the designer I can not change any properties (property window is read-only) of the Toostrip or add new buttons on it. All changes I have to do must be done in code instead of using the designer. ToolStrip-modifier property is set to Public.

View 17 RepliesI wonder how you can make a picturebox selectable at runtime and also change the size and location during runtime?
Well I know how i can change the location of a picture box during runtime but that is only with a picturebox that is already defined in the form before runtime.
So I write an event for that particular Picturebox.
But now i want to do the same thing with a picturebox that a user can add during runtime and then the user should be able to select and move the picturebox.
So now i can't add code to the picturebox event so I wonder how you should do this. ( Maybe with reflection?)
And what if the user added 10 picture boxes and selects a certain picturebox. How do you make it possible that the picturebox the user clicks on is selected?
Should you store each picture box location on the Panel and then when the user clicks on a certain pixel in the panel where a certain picture box is it get's selected?

View 5 RepliesI have my own control which inherit System.Windows.Forms.Control The only functionality that this control requires is the capability of losing and gaining focus. I learned this requires the control style of selectable to be applied which is descriptive as exactly what I'm in need of, "If true, the control can receive focus.".
However after applying this style in my code, the control still refuses to have anything to do with gaining or losing focus. Other styles I have applied to this particular control are as fallowed
UserPaint, AllPaintingInWmPaint, and SupportsTransparentBackColor. I'm not sure but perhaps one of these other styles interferes with the one that's not working properly.
I have a ComboBox that is databound to an ObservableCollection of strings. The ComboBox is also editable, so you can either enter in your own value or select one from the list. The issue I'm running into is the index of SelectedItem seems to be the index of the last item you selected when you've entered in your own value in the ComboBox, though it's -1 when you have IsTextSearchEnabled set to true. The problem is, if someone entered their own value and then decide to instead select the item on the ComboBox that had been selected before, the index doesn't change so the SelectionChange event doesn't fire. How could I get an event to fire in this situation?

I have a number of lines of text on an .aspx page that I want a user to be able to edit, I am not storing this text/information anywhere in the database. I just want it to be information that is displayed to the user but can be editable, so the user can view the text and if there is a mistake or want to make a change they can do this by editing it.
I have seen that if you display data in a label and put a textbox beside it then, the textbox can move into the place of the label - I have done this for other text on the page however that method would not fit for this purpose because I require this edit of text to be for a number of lines.
I'm sitting in a VB-project and i have a ListView with 3 cells; a checkbox, a name and another text value. I want the last cell to be editable for the user. The second cell is also okay to have editable, no problems at all.

View 2 RepliesWhile I am asking this for VB I verified this issue also occurs in C# so I think it is a .NET issue. I am using Visual Studio 2010 Premium Version 10.0.40219.1 SP1Rel with .NET Version 4.0.30319 SP1Rel.
Step to recreate the problem.
Create a new Windows Application for Visual Basic (WinForms).
Add a ToolStrip.
Add a ToolStripComboBox to the ToolStrip.
Save, note the width of the combo box.
Change the padding on the combo pax to 2.
Save and close the form designer.
Reopen the form designer, look at combo box width - it decreased. Note that form is marked as having been modified. So save it and close the designer again. Reopen the designer and look at the combo box width - it will have shrunk every time you save, close, and reopen until you get to a 0 width. It shrinks by 4 * the padding size. Why would padding affect the size since that is the interior margin where as the margin settings are the exterior margins.
I have created a search/query facility after watching one of Beth Messi's videos. I notice that we can convert the textboxes on the auto generated search toolstrip to buttons, comboxes, etc. So, when we wanna search for a data in the datagridview, we enter a keyword. I wonder if it is possible to change the textboxes to comboboxes and make it bind to the datasources, so that users can use the drop down, instead of typing?
View 6 RepliesAll I want to do is build some kind of table-like or grid-like control in my form that has two columns. An element in the first column should be a checkbox that is changable by the user, and an element in the second column is some un-editable text. Of course, when the user checks or unchecks a checkbox, I have to be able to handle that event and figure out which row it came from.I've been trying this all day with no luck. Do I use a ListView or a DataGridView? If the answer is DataGridView, do I add columns and rows to it directly or do I try to make a DataTable which I then assign to the DataGridView's "DataSource" property?Is is possible to make editable checkboxes in a DataTable? I succeeded in making checkboxes by making a DataColumn of type boolean, but then I couldn't check or uncheck them during runtime.

i have a given table structure with some data inside. Here is the database model: Database Model..In the TBL_SCENARIO Table a user can store an unlimited number of scenarios. In the TBL_EVENTS can each scenario have an unlimited number of so called Events like risks.The TBL_EVENT_DATA Table stores now for each day and for each event in a scenario the value min and max.I would like to edit a scenario with its events (! not an single) in a GridView Control. Is this possible? I would like to have the rows as days and the columns (2columns for one event) as min max value for the events. So is it possibel, when i have 5 events, have these in 10 columns (2 columns for each event [min] and [max] and then the days as rows?
View 4 RepliesFor example lets say I want only admins to be able to see and edit CustomerID in details view, moderators can see this value but it is not editable, and regular users cannot even see it.
View 2 RepliesI need a control that will allow me to do a few things.
The control should be similar to Listview in detail mode, in that it lets me show numerous rows, each row with multiple columns. However, I want it editable in place... that is, the user can (if I let him) click on a column and change what is stored there.
The next thing I need to do is set a graphic in one column, text in another, a playback controller in a third, and a trackbar control in the fourth. Every row will look like that.
The final thing I need to do is be able to control how a row is painted... either the entire line or by putting a graphic image (like a button) in a column when it is not being edited.
Barring all of that, I can put all the controls I need into a single user control, then I need some listview-like control that will allow me to add that control to it.. and have it be operational.

View 1 RepliesI really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.

I'm trying to make the combobox get suggested values from a website using the current keyword they have in the box already. For example if I have O, it will show up values that the website has returned with O. The problem is how can I make it work where whatever I type into the combobox, it will get the values, set the datasource and make it show up. So far I have this:The problem is whenever I type something, I cannot get it to set it to the new datasource without the comboxbox becoming the first value in the data source.
Dim pop As New List(Of String)
pop.Add("Koolaid")
pop.Add("kIMKY")
pop.Add("KoolPaid")
ComboBox1.DataSource = New BindingSource(pop, Nothing)
