Automating click on RadGridView row throws FindElementException in Testing Framework Testing Framework

I'm trying to automate a click on a RadGridView row to get it to enter edit mode. My UI is brain-dead simple, as I'm just evaluating the test Framework for use in our real application. It's just a RadViewGrid in a Window. I'm using MS Test to run the UI tests. I'm just binding the RadGridView to a collection of dummy objects. The test looks like this:

public void CanObserveCellContent()

{

var grid = wpfApp.MainWindow.Find.ByName<RadGridView>("_searchResults");

grid.Rows[0].User.Click(MouseClickType.LeftDoubleClick);

//other steps and assertions

}

The second line simulating the click throws the exception. But if I change the second line to this and comment out the rest of the test:

Assert.AreEqual("Test1", grid.Rows[0].Cells[0].Text);

the test passes. What is it about clicking automation that makes it unable to find the row?

Hello Brian,

You really need to pick a specific cell to click on:

RadGridView grid = ActiveApplication.MainWindow.Find.ByName<RadGridView>("RadGridView1");

grid.Rows[1].Cells[2].User.Click(MouseClickType.LeftDoubleClick);

All the best,

Cody,

Thanks for the reply, but the same exception is thrown when I change the code to perform the click on a cell instead of the row. I get the following exception:

ArtOfTest.Common.Exceptions.FindElementException: Unable to find the specified element: Unable to find the element of type: gridviewcell

Any other ideas? Do you need more of my code to look into this?

Hi,

What I really need is a copy of your WPF application (source code or .exe) so i can reproduce this problem. I am not able to reproduce it using our WPF samples which include a RadGridView.

Kind regards,

Hi Brian,

Thank you for the project. I was able to reproduce the problem with it. I don't know what's going on exactly, possibly a bug in our WPF RadGridView translator. I found I can overcome it by manually fetching a list of all the GridViewRow's like this:

RadGridView grid = ActiveApplication.MainWindow.Find.ByName<RadGridView>("_searchResults");

IList<GridViewRow> rows = grid.Find.AllByType<GridViewRow>();

rows[0].Cells[2].User.Click(MouseClickType.LeftDoubleClick);

I'm going to file an internal bug to try and get to the bottom of why grid.Rows[0] doesn't work as expected with your simple application. Kind regards,
Cody

Looks like I spoke too soon. I replied before trying your workaround. I'm still getting that same exception when I try to perform the click. I created another test method with only the code you posted, and I still get the FindElementException. Any clue why I'd get the exception and you wouldn't?

Hello,

Just a quick follow up to document the outcome of our meeting.... I can't explain why you're getting the exception. You will work on upgrading the version of the Telerik WPF controls installed on your machine to at least .725 version to match what I'm using since I don't get the error on my machine using the same code.

Greetings,
