Somehow my datagrid consider whole column as integer when each cell of that column has numbers. And it wont allow my to update cell with text value. I dont want to have any kind of validation on my grid. How do I disable validation from every cell.
here is image of what I have:
declare you clr properties as string.

Apologies if this has already been asked but I cant see that it has been.
A Winforms DataGridView has an 'AllowUserToAddRows' property. Is there a way to ensure a new row is only added if certain conditions are met?
For example, I have a DataGridView with two columns, the first is a TextBox column, the second a ComboBox column. The 'AllowUserToAddRows' property is set to true.
However, I wish a new row to be added only if the user has entered a positive number in the TextBox column and made a selection from the ComboBox column. Currently a new row is added when anything is entered in the TextBox column, or if a selection is made in the ComboBox column.
Many thanks in advance
I am having wpf datagrid where I have to restrict user from entering duplicate values. I am using IdataErrorInfo for validation. When I enter duplicate value in cell, it is highlighting only one cell which is currently I am modifying. But I want to highlight another cell having same value. Can any one please suggest any approach for this.
Thanks,
Here is an example image of a datagridview.
I'd like to make this row based so instead of a cell being selected I'd like the entire row to be selected. The rows/cells are read only so no cell needs to be edited. also I like to remove the leftmost side where the > is.

myGrid.RowHeadersVisible = false;
myGrid.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
You can set these properties in code as above, or via the designer. RowHeadersVisible is under the Appearance section. SelectionMode is under the Behavior section.
For the full row select part of the question, the DataGridView control has a property called SelectionMode. Set that property to SelectionMode.FullRowSelect.
Not sure if the leftmost part can be removed but you can changed the width of it to 1 or 2 pixels. Cannot remember what it is called but there is a property on the DataGrifView control that controls the width of that first 'row indicator' column.
I'm new to Silverlight, so this might be a simple question to answer. I have a grid (not DataGrid from the toolkit), so that data displayed in it can be easily tabulated. I want to bind the grid to a string array that never changes, hence the number of rows and columns in the grid will not change either. I see that I cannot specify a template like I can for a ListBox (ListBox.ItemTemplate) and I don't want to define each row and column explicitly (with a TextBlock in each one of them) in XAML. And I also dont want to generate rows and columns dynamically in code behind as it is not blendable. What's the best way to do this?

I need a control that can list data in 3 columns, I want to manually add the items (not databind the control).....
firstly I'll populate column 1 and 2, then later when a button is clicked, I need to loop through the values of column 1 and 2, perform an operation, then update the value of column 3.
From what I remember the datagrid does not allow for this , and must be bound to a data source, am I right?
What is the best quick drag and drop control I can use from the toolbox?
Use a ListView with View property set to Details. Then you can add columns to the listview.

This is not right. The DataGrid can be used in bound or unbound mode. If you don't bind it, you can just add rows and columns and populate cell contents as you need. You could choose to do this if you wish. It will solve your problem.
But I think it would be simpler for you to create a custom class to represent a row and use the DataGrid in bound mode. You can refresh the binding when you click the button.
