Hi,
I'm usign two webgrids with one webgrid holding all order headers and another webgrid holding all order details.
If I click a row in the order header webgrid, the order details webgrid should refresh accordingly and show the correspondign order details.
This is working.
but if I try to filter any order in the order header webgrid it gives out string input error.
Pelase find the attached codes for reference.
Please confirm if the screenshot is the current error that you faced or not. Your sample will show this error because keyvalue is null or empty when select the filter row. To resolve this issue, simply set the validation to check keyvalue is undefined/null or not.
Also, I don't recomment the code that you used to get key value because it uses the element.
Not all of the element have this attribute. It would better if you get the row object instead of element.
e.g selRow= grid.GetSelectedObject().ToRowObject();
Hope this helps.
