Hello Abhinav,

First of all, I will answer your second question. There is online documentation for Infragistics Coded UI Test Extension. Follow the next link to overview of this extension http://help.infragistics.com/Doc/WinForms/current/CLR4.0/?page=Coded_UI_Test_Extension_Overview.html. You can also check this link, where is shown how you can use Coded UI Test Extension to edit a cell in the UltraGrid.

Regarding your second question I am not sure if I understand what your issue is. Can you please try to describe in details what happens at your side when you try to edit the cell’s value?

Looking forward to your reply.

One possible way is to iterate through all the rows in the grid and check the value of the cells in the first column. If the value match the one you need click on the cell in the same row in the second column and set its value. Please check this thread in our forum, where was discussed and shown how you can iterate through all the rows in a grid and get the cells’ values. When you get the cell value you can check it against the one you need. If the value match the one you need you can get the AutomationElement of the cell in the next column, click on it and set its text.

Here is a sample method doing all this:

public void SetCellValue()
{
    UITestControl uIColScrollRegion0RowSTree =
        this.UIForm1Window.UIForm1Client.UIUltragridCustom.UIDataAreaCustom.UIColScrollRegion0RowSTree;
    UltraUiaEdit uIUltragrid_EmbeddableEdit =
        this.UIForm1Window.UIUltraGrid1Window.UIUltragrid_EmbeddableEdit;

    int rowIndex = 0;
    AutomationElement containerAutomationElement =
        uIColScrollRegion0RowSTree.NativeElement as AutomationElement;
    AutomationElement rowAutomationElement = null;
    ItemContainerPattern containerPattern =
        containerAutomationElement.GetCurrentPattern(ItemContainerPattern.Pattern) as ItemContainerPattern;
    rowAutomationElement =
        containerPattern.FindItemByProperty(
            null,
            AutomationElement.AutomationIdProperty,
            rowIndex.ToString());
    while (rowAutomationElement != null)
    {
        // get the collection of cell automation elements
        AutomationElementCollection cellsAutomationElements =
            rowAutomationElement.FindAll(TreeScope.Children, Condition.TrueCondition);

        // get the automation element for the cell in first column
        AutomationElement cellAutomationElement = cellsAutomationElements[0];

        // Scroll the cell into view
        ScrollItemPattern scrollPattern =
            cellAutomationElement.GetCurrentPattern(ScrollItemPattern.Pattern) as ScrollItemPattern;
        scrollPattern.ScrollIntoView();

        // use the ValuePattern to get the Value.
        ValuePattern valuePattern =
            cellAutomationElement.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
        var cellValue = valuePattern.Current.Value.ToString();

        // check the cell value
        if (cellValue == "Cat")
        {
            // get the automation element for the cell in second column
            AutomationElement nextCellAutomationElement = cellsAutomationElements[1];

            // get clickable point on the cell in second column
            Point poinToClick = nextCellAutomationElement.GetClickablePoint();

            //  click on the cell
            Mouse.Click(poinToClick);

            // set the cell Text
            uIUltragrid_EmbeddableEdit.Text =
                this.RecordedMethod1Params.UIUltragrid_EmbeddableEditText;

            // get clickable point on the cell in the first column
            poinToClick = cellAutomationElement.GetClickablePoint();

            //  click on the cell
            Mouse.Click(poinToClick);

            break;
        }

        // get the next row
        rowIndex++;
        rowAutomationElement =
            containerPattern.FindItemByProperty(
                null,
                AutomationElement.AutomationIdProperty,
                rowIndex.ToString());
    }
}

Please let me know if you need any additional information.
