How to: Retrieve value of cell in selected row

[Michael]

Hello everybody

After doing researches in all available source I still can not accomplish this probably trivial task. I would like to read the values of various cells of the row which is selected. The sample I found in this forum deals with a business object (Person). I'd expected something like:

myValue = gridview.selectedRow.Columns("NameOfThisColumn")

Thanks for your help in advance

Hi Michael,

 You can cast SelectedItem property to your type and access directly desired property. For example:

var city = ((Customer)RadGridView1.SelectedItem).City;

Thank you Vlad for your prompt answer

I do not have a type. All I want is to retrieve the cell value and show it in a text box. Do you have a code snippet in VB.NET. I am sorry for not seeing the easiness of your answer but since I am very new to WPF and also have strong paradigms on VB6 and DAO, it is very hard to complete even trivial tasks ;-)

thanks in advance

Hello Michael,

Generally you always have a type :). How the grid is bound in your case? Here is the same code for VB.NET:

Dim city As String = CType(RadGridView1.SelectedItem, Customer).City

If you prefer you can get desired value using reflection. Please check the attached project for reference.

hello Vlad

thanks again, I (try to) have one last question:

>>Dim city As String = CType(RadGridView1.SelectedItem, Customer).City<<

My Gridview is bound (.timesource) to a datatable which autogenerated various columns. Let's say the column "LastName" contains the last name of a customer. This value should be read. So I assume that the right code would be:

dim LastName as string = ctype(RadGridView1.SelectedItem, ?).LastName

Is this correct and what would the equivalent for your variable "Customer" in my sample case?

(I have not looked in your sample project since I am building a WPF and not a Silverlight application and I have a tremendious timely pressure)

thanks in advance and best regards,

Hello Michael,

 Sorry for the Silverlight application - my mistake! Here is an example with DataRow:

dim LastName = CType(RadGridView1.SelectedItem, DataRow)["LastName"]

hello Vlad

>>dim LastName = CType(RadGridView1.SelectedItem, DataRow)["LastName"]<<

my IDE is complaining the ["LastName"]". Unfortunately I can only write the German language comment of the IDE saying "Bezeichner erwartet". The is pointing to the '"' right after the [.

???

thanks for your Help and best regards,

Hello Michael,

 Sorry again! Here is the correct VB syntax:

CType(RadGridView1.SelectedItem, DataRow)("LastName")
