How to edit a ListView row programmatically? - c

I need to edit the values of an existing ListView row (i.e change the values of an Item and its Subitems).
I need to do that programmatically and not by clicking on the ListView item at runtime to rename it.


just use LVM_SETITEM as documented.

On Click on the RowHeader the current row should be editable and On click of the columnHearder current column of all row should be editable

I have a silverlight DataGrid, by default on page load the all the cells of the datagrid should be Readonly. I have 2 problem , can any one help me?
1.On Click on the RowHeader the current row should be editable
2. On click of the columnHearder current column of all row should be editable

This might not solve your entire problem but it should partially address it.
This is to make a column read-only in a datagrid
DataGrid.Columns[7].IsReadOnly = true;
Obviously the property can be changed from events but the data grid does not have row/column headers event handlers. Custom controls seem the way to go without introducing any new gui elements like buttons and changing the feel of the application.

Datagrid Row Selection On Button Click In WPF

I am having a Datagrid that gets populated with values from a DataTable. In my program i have four buttons: Goto First, Last, Next and Previous, as the name name indicates i have to select the rows based on the selection made using these buttons. Everything seems well if i use the below code to get the row (for example first row).
DataGridRow row =(DataGridRow)userControl.m_DataGrid.ItemContainerGenerator.ContainerFromIndex(0);
row.IsSelected = true;
But the code throws null value when there is more rows than the height of the Datagrid(When scrollbar comes into picture).
Please help me out of this issue. I think this is because of the view problem.

Due to virtualization the containers are only created when the object is in view, so you could first scroll the item into view using the respective method, wait for the creation of the container and then select it.
As this is rather messy i would suggest binding the IsSelected to a property on your item using a style for DataGridRow (set it as ItemContainerStyle). Then you can just set the property to true and scroll the item into view if need be.

Combo Box, More Than One Item In A Row

I'm adding image items to a ComboBox, as you know ComboBox shows just one item in a row, but I want my combo to show more than one, and show images like they are all beside each other with a little space around them, so the user can pick one...
Any Help is pretty much appreciated...

You need to change the ComboBox.ItemsPanel to a WrapPanel.

You would have to edit the ItemTemplate and the ItemsPanel.
Right click the combobox and select Edit Aditional Template --> Edit Generated Items --> Create Empty
Add an image and a text to a Vertical StackPanel in the template and set the bindings.
Now leave the template editing and right click the combobox again.
This time go to Edit Aditional Template --> Edit Layout of Items --> Edit a Copy
Change the StackPanel to a UniformGrid and set the Columns property of this to 2.
The result should look a little like this:
I used sample data in this example. 2 properties: one image, one String(Name).

Binding a combobox to a database and gridview

I am displaying a database table on a grid view and displaying a selected item's details in a detailsview.
Here's the problem:
There's a combobox in the detailsview and I want to display the added value's string on grid and I want the combobox to select this value.
It will be possible to update, delete the selected item from grid or add a new item. And I couldn't do the transformations of string- comboboxitem-database item. And I am quite confused on the binding operations. I hope my question is clear enough. Thanks in advance for any help.

One solution that may preserve your sanity. Only allow edits in your detailsView. Use the grid to Add (clicking an Add Link which shows the detailsView) or Delete. Is it really necessary for the user to be able to edit in either place?

WPF DataGrid: edit all cells, new row position, click once to edit

I was wondering if anyone could point me into the right direction with DataGrids.
I'm trying to position the new row at the top of the grid
When the user clicks a cell all cells in the row move into an editable state.
Cheers

Check this out for single click editing:

And this for New row formatting:

I think positioning a new row on top might not be possible as the new item row is not part of the DataGrid's control template. Haven't given it a try though.
