Hi Ediberto,

Sorry for the delayed response.

Please try using TableControlCheckBoxClick and RecordValueChanged changed events with conditional statements to achieve your functionality.

Refer the sample from below link:

Please let me know if you have any queries.

Hi Lingaraj

I downloaded your sample but occurs an error while I runs:

'Syncfusion.Grouping.Record' does not contain a definition for 'GetRowIndex' and no extension method 'GetRowIndex' accepting a first argument of type 'Syncfusion.Grouping.Record' could be found (are you missing a using directive or an assembly reference?)

Can you help me?

I´m using the version 6.3.0.30

Thanks

Hi Lingaraj,
I solved this problem using the GetSourceIndex() method:

int row = e.Record.GetSourceIndex();

I have a second question.
How do I do mark the checkbox, unmarking the other checkbox when I click other row from other column Value from the example?

Thanks

Hi Ediberto,

Thank you for the update.

Please try using CurrentRecord in conditional statement to achive your behavior.

Refer the modified code below:

// Modified  RecordValueChanged event
void Table_RecordValueChanged(object sender, RecordValueChangedEventArgs e)
{
if (e.FieldDescriptor.Name =="Value") 
{
if (!changing)
{
changing = true;
foreach (Record rec in e.Record.ParentTable.Records)
{
if(rec!=e.Record.ParentTable.CurrentRecord)
rec.SetValue("Value", 0);
}
changing = false;
}
}
}

Please let me know if you have any queries.

Lingaraj S
