I need that every file of the listView has a button in the first cell. Is that possible?
I was using the same item click event on another listview, and it worked perfectly... I don't know why this is happening, but here's my problem:
When I double click on an item, and try to obtain its index in the listview, the items index always comes back as -1... Obviously -1 isn't an index, and I'm guessing that it is returning -1 because that item does not exist on the listview, but from what I'm seeing, it is impossible for the item not to be inside of the listview...
Here is the xaml for my listview:
<ListView x:Name="lstBookmarks" HorizontalAlignment="Left" Height="250" Margin="10,10,0,0" VerticalAlignment="Top" Width="327" ItemsSource="{Binding Bookmarks}">
<ListView.View>
[Code]....
When I uncomment the MessageBox, it shows -1... This is obviously not right lol. I have the same exact click event in another class, and I obtain the items index the same exact way.. The only difference between this listview and that one is that this listview is databound.. Is that the issue? If so, how does one overcome it?
I have 3 columns already made Product, Price, Quantity, - what I want to do is take the textbox's txtName, txtPrice, txtQuantity, and add them to the columns in the right specific places.
View 2 Replies View RelatedI'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.
How to display the item in listbox,which are selected from three combobox.
View 1 Replies View RelatedI have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?

When I go into the .rc file and remove all of the MENUITEM SEPARATORs all the menu options are squished to the left of the menu as in the screenshot. As long as there is just one MENU SEPARATOR anywhere the menu is fine. If I could make the application without MENU SEPARATORs that would be awesome.

How do I get the path for a selected item in a list control?
View 5 Replies View RelatedI need a ownerdraw CListBox where I can change the item height during working with the list. The msdn says that I can specify the height in OnMeasureItem when the listbox will be created (ownerdrawfixed) or when an item will be inserted (ownerdrawvariable).
How to change the height e.g. when I click a button?
I made also some tests with CListCtrl. There I can change the height. But there is only one height for all items. How to set individual heights for the items?
I quite often use an ide written in assembler: RadAsm3[URL] .....
It has a menu item to explore current path. I have used other ide's that have a similar feature but:
The one in RadAsm3 will activate a current Explorer window if the current path is the same as the one requested.
All others open a new Explorer window.
I would like to implement the RadAsm3 approach using Visual Studio 2013 Community c++ as my host compiler for testing.
I tried to get the title of current windows but it appears ShellExecute "explore" does not produce a conventional window???

I am using a CEdit control as a child in a CListCtrl for purpose of making each column editable. The application is a dialog based app. My problem is... I have overwritten OnOK and OnCancel in the main dialog so the edit control never receives notifications for Escape or Enter whether in OnChar or PreTranslateMessage and I would like to delete the CEdit control after updating the CListCtrl on Enter. What can I do? I have rewritten this code many many times over the past 4 days and nothing is working.

View 6 Replies View RelatedIn short I'm converting a floating point bilinear image resampling routine into one that only uses fixed point arithmetic. I've gotten rid of nearly all the floats now, in fact all but one and the results at the moment are in distinguishable from the floating point version. It's a maths issue really. Some pseudocode goes like this.
Code:
for( int xx=0; xx<ow; xx++ ) {
int_center = (ccx >> 16);
int temp = xx * 2;
for (j = int_center; j <= int_center + 1; j++)
[Code] ....
Where ccx is and integer error accumulator that gives me a scaled integer. Shifting down buy 16 gives me the relative pixel I need to be working on. The line just after where the inner loop begins is where I have the last remaining float. FILTER_FACTOR is essentially a percentage by which I scale the error accumulator to the correct amount.
For example.
ccx = 98303. Which is a value of 1.5 when shited down by 16 bits. Obviously I can shift it because it will round and I lose the precision. Lets say FILTER_FACTOR is 39321. Which is 60% of 1 (65535) So what I'd like to know is, is it possible to use the FILTER_FACTOR as an integer and do some fancy integer math to scale the result from (ccx - (j<<16)) by the representative amount that is FILTER_FACTOR. In this example 60%. Effectively getting 40% of (ccx - (j<<16)) At the moment FILTER_FACTOR is still a float and therefore 0.6, which of course works just fine.
at the moment I lack access to the pc with the code on it, so for now I will try to keep my question basic.
now here is my problem: I have a listview witch is populated by user input(lets say for the ease of argument that the input is "first-name" "last-name" and "e-mail adres") all of with get there information from textboxes.
then all the information gets stored in a list and on closing that list is stored in a xml-file in the following format
<Root>
<Data>
<first-name>
Samual
[Code].....
the input, saving and loading is no problem. when you open the file this listview is in view = List so that you only see the last-name(I prefer it that way since I know how to code that) and when you click it it fills the textboxes with the corresponding information.
what I am trying to figure out it how to make it that it sorts itself(preferred sorting when something is changed).
I tried the ListView.sorting = SortOrder.Ascending; when I do it that way it messes up the corresponding information(is it clear what I mean or do I need to add an example).
i'm making a hotel reservation system for our final project in database management.. i'm having difficulty on how can i attach an image in a listview, if i insert a room category, the roomstatus will automatically insert a value of 1 on the table, and in the listview the data 1 in the column of status must be view as an image that indicates that the room is available...
View 4 Replies View Relatedi have a list view, which is shown below as an example, i am hoping to achieve to find out a method of adding up the values in the Sub2 Column in C#. Then i will output it to a label on my form. So the total should be 14. But i don't have a pre-defined number of rows, and thats what i needs to be. I thought of something like
label1.Text = ListView1.SubItem2.text
But no such luck....

I've been trying for a while now and I can't seem to replicate this model without using a grid. I've tried making some simple custom panels and a wrappanel that makes a new column after n pixels or n number of items which works; however, I'm unable to find a way to stagger each column.
Here's an image of what I'm trying to do:
enter image description here
I've made solutions that use a Grid that do stagger the columns however what I need is a panel that uses columns only and it must be able to be used as the itemspanel for a ListView.
I'm trying to use a listview component to show all the fonts on my system, and display each item (row) in the actual font design.
When I run the following code, nothing displays in the listview.
If I rem out line 4, then the list populates with all the fonts, but of course, in the default listview font.
I thought I read somewhere that each item in a listview can be set to a different font.
int i = 0;
foreach (FontFamily oneFontFamily in FontFamily.Families) {
listView1.Items[i].Font = new Font(oneFontFamily, 10);
listView1.Items.Add(oneFontFamily.Name);
i++;
}
//user list view
da = new SqlDataAdapter("SELECT * FROM [user]", con);
