I'm trying to find an event for the combobox when its selected value changes , but I can't seem to find the right one since I've tried several events in the dataGridView that are just triggering at the wrong moments. I need to remove the selected item from that combobox so that it doesn't get selected again at the second combobox which usually have the same items .

I'm using listView to show content (selected item) in ComboBox, TextBox, Labels..
I was using
DropDownStyle = DropDown
and actually i use DropDownStyle = DropDownList.
With this change,
comboB.Text = Name;
stopped working correctly (onload), only work after first click any item. Why?
I tried too
private void comboB_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
but with copy/paste with mouse i can add text in ComboBox.
PS: My objective is combobox no editable.
I want to add ComboBox inside ListView on mouse double click event. On each double click, a new ComboBox should be added on the next row.
I tried it with the code below, but its not working.
private void form_DblClick(object sender, form_DblClickEvent e)
{
ComboBox c;
this.Controls.Add(c = new ComboBox());
c.Items.Add("Input");
c.Items.Add("Delay");
c.Items.Add("Message");
c.Items.Add("comment");
listView1.Controls.Add(c);
}
actually i want to add combobox will all of the above elements in one combobox..when i double click it again..in next line another combobox will be added with all elements...
I have a secnario where I have few tab controls one ineide the other, where my real tab pages containing the data are 4 level deep. This entire structure is dynamically built from a data base.
Now I have a tick event, on whice I want to update the data in the currently selected tabpage.
How can I find it, recall that I have many tab controls, each has a tabpage with another tab control an so forth...
Two ideas I had in mind, I though I caould generate a list of all my data TabPages and itterate it, but I failed to find an indicator of the selected tab.
Another idea was to track the currently selected tabpage via an event, but I feared that I might miss somehow the track and my update the wrong tab page.
Last idea was really unelegant - Look at the main control, get the selected tab page, find the tab control on that page via searching its controls, than find this control selected page, and do the same until I reach the 4th level.

I have been learning C# so I've been dragging and dropping. I have a "First Name" and "Last Name" text field. I want to add this to a combo box called something like "User List", which will list the last named then the first names. However I figure I can work with something that can get me to store the names in the combo box.
So. I have two things I need to know:
What do I have to do to have when the button is pressed, add to the combo box?
Is there a way to retain all the entries I have entered? Or no?
I'm having issues with selecting the next item in sequence in a combobox dropdown. The dropdown consists of letters A-Z and there is a timer that I have running to change the letter every x minutes. What I need to do is if, for example, letter A is selected, when the timer goes off, it will change to letter B, etc. If it's at letter Z, it needs to go back to the first item, letter A.
letterCode.SelectedIndex = letterCode.SelectedIndex + 1;
if (letterCode.SelectedIndex >= 26)
{
letterCode.SelectedIndex += 0;
}
I have the above, but I keep getting an error:
InvalidArgument=Value of '26' is not valid for 'SelectedIndex'.
how to get this working (letter changing logic block).
I have a comboBox that I created in XAML using using binding and I'm unable to get the selection. I've tried everything I could think of or find on, but no luck.
Here's the relevant XAML and C# code for the comboBox:
<ComboBox Name="projSelected" Selectionchanged="projSelected_Selectionchanged" HorizontalAlignment="Left" Margin="424,27,0,0" VerticalAlignment="Top" Width="199" DisplayMemberPath="proj"/>
projSelected.ItemsSource = DAL.projectList;
Then here is where I try to check the selected value:
private void projSelected_Selectionchanged(object sender, SelectionchangedEventArgs e) {
projectDataList.ItemsSource = null;
projectDataList.Items.Clear();
[Code] ....
And here is my output in the MessageBox that I'm using to test the code:
Quote
project=Website selected=employeeProjects.project
I've been working on making a sprite generator and this is one thing that has kept giving me difficulties. No matter what I've looked up nothing directly says how to nor can I find anything on a similar topic to try and apply to it either. I know how to add the resources and names for the options but how do I get the options to make my picturebox image change in relation to the selection?

I have a combobox that lists the years 1981-2013. Beside it, a simple Enter button.
I wanted to be able to assign individual lines of text to each year that would be displayed in the message box.
Like if the user selects 1981, clicks Enter and the message box displayed "In the year of 1981.." but if they select 1982, the message box displayed "In the year of 1982.." I have everything else I want working, except that I can't figure out how to assign different lines of text to different years.
I have a data-bound ComboBox and I populate a DataSet with the values returned from a SQL query.
public DataSet CompanyArray(DataSet dataSet) {
SqlConnection connection = InstancesTest.IDataInterface.DefineConnection();
SqlCommand command = new SqlCommand();
command.CommandText = "usp_CompanyArray";
command.CommandTimeout = 20000;
[code]....
All this works fine. The reason I populated it in an array was so that I could sort the items alphabetically. I know I could just do an "order by" in SQL but I chose this route.
What I'm after is putting a "Please Select" at index 0 in the ComboBox. How can I move this value to the top of the list, without reordering the sorted list?And I don't really want to insert a "Please Select" as a first row in a database table.
I have a combobox which doesn't have the CBS_SORT style and after adding some items I'd like to offer the ability for the user to sort it alphabetically by clicking on a given button. How can I sort the combobx after it has been created and some items added to it ?

I can adjust the combo box width and also the dropdown list height but not the combo box height.
i need to change the text in multiple ComboBoxs. i could do it one by one, but i have about 11 i need to change. i feel like doing it one at a time is not efficient. i was wondering if i can put the comboboxs into an array so i can use a for loop to change them all with out writeing it out 11 times.
View 9 Replies View RelatedI am creating one c# project. In this project I have one mdi form and many child forms.
All the child forms contains one panel named as panel1.
Now when child form opens i use the following code in all child form all child forms' load event contains the following line.
this.WindowState = FormWindowState.Maximized;
and all child forms' resize event contains the following line.
panel1.Left = (this.ClientSize.Width - panel1.Width) / 2;
panel1.Top = (this.ClientSize.Height - panel1.Height) / 2;
so my question is if possible that the above code i write only once so i donot write this code in all the child forms load and resize event.

I am writing a application that receives Event messages from a network device the problem I have is that the device sends some message 5 times per tiggered event on two of the events I like to use the rest of the messages are fine I need to create code to filter out the other 4 last messages that get displayed in a textbox the 5 message are identical I have added a timestamp to the sting and noted they are always 1 second apart so the format would be somthing like this:
11:23:01 - x - y
11:23:02 - x - y
11:23:03 - x - y
11:23:04 - x - y
11:23:05 - x - y
What I would like to do something like this, always append the first message to the textbox but ignore or even change the 4 messages that follow 1 second apart from each other that contain - x - y if any other message appears it should still append the text box as well
so the result i would like for the 5 event message as above should end like this:
11:23:01 - x - y
11:23:02 - custome message / ingnore append to textbox
11:23:03 - custome message / ingnore append to textbox
11:23:04 - custome message / ingnore append to textbox
11:23:05 - custome message / ingnore append to textbox

I'm still at the very beginning of learning WPF and there are still countless things i don't fully understand. For instance, as I can see in my WPF project, there isn't an event that would fire when the Background property of some control is changed. Or am I just missing it? If i'm not blind after all, and it really doesn't exist, is there any way i could get notified when the Background color of some control is changed?
