See more: C# UI DataGrid Automation
I'm writing a UI automation software. I need to select a row in the datagrid and then click on the run button. I tried most of the example codes in the internet and they didn't work for me. For example for selecting a gridview row:

When I write the following code:
AutomationElement dataGrid = this.mainWindow.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.AutomationIdProperty, "2885"));
if (dataGrid != null) {
GridPattern pattern = GetGridPattern(dataGrid);
AutomationElement tempElement = pattern.GetItem(1, 1);

I receive the error: "Target element cannot receive focus." which is related to the last line.

I also tried the code:
AutomationElement mainGrid = // find the grid in the window var columnCount = (int)mainGrid.GetCurrentPropertyValue(GridPattern.ColumnCountProperty);

var mainGridPattern = (GridPattern)mainGrid.GetCurrentPattern(GridPattern.Pattern);
var rowToSelect = 2;
// select just the first cell var item = mainGridPattern.GetItem(rowToSelect, 0);

var itemPattern = (SelectionItemPattern)item.GetCurrentPattern(SelectionItemPattern.Pattern);

but I and I received the error :"Unsupported Pattern".

I should mention that I'm using UI Spy for retrieving the elements properties.

Could you explain me what's wrong and how should I select a row?

Been a while, but check this out

GridPattern does not support active manipulation of a grid; the TransformPattern control pattern is required for this functionality.[^]

Thank you for your answer. The Transform control "Represents a control that can be moved, resized, or rotated within a two-dimensional space.", so it's not what I'm looking for. Can anyone help me to get it work?
