I want to set the default value of the row when performing inline edit add in Grid.

Question

Hi!If you click the Add button of the Toolbar in the Grid, a row is added and you can enter a value.What I want is to dynamically insert default values for each row position. The reason is that action values such as sort order can make sense.I know that among the GridColumn properties of the Grid, static inserts that are not dynamic can be given as DefaultValue.What I want is a way to set default values for edit columns by putting values in specific properties of DataRow or Data in events like AddBegin.To my intuition, I thought args.Data would do that, but no matter how much I set the value, it doesn't reflect.Where is the correct location?Thanks!

Hi Seil, 

Query#:- A common approach is to set a value in args.Data when the RequestType of OnActionBegin is Add when the add toolbar button is pressed. This works fine for Grid, but no changes to TreeGrid. 

We are able to replicate the problem at our end. We have confirmed this issue “Need to set default value on performing Add operation using args.Data from OnActionBegin event” as bug. Thank you for the taking the time to report the issue and helping us improve our product. At Syncfusion we are committed to fixing all the validated defect (subject to technological feasibility and Product Development Life Cycle) and including its fix in our subsequent release.

Hi Seil,

Greetings from Syncfusion support.

Based on this requirement, we suggest you to set the args.Data values for the corresponding fields in the OnActionBegin event of Grid by checking for the RequestType as Add. We have prepared a sample based on this scenario, please download the sample from the link below,

Sample : https://www.syncfusion.com/downloads/support/directtrac/general/ze/Serversample-1546685424

Please refer and use as like the code below,

<GridEvents OnActionBegin="OnActionBegin" TValue="Order"></GridEvents>
public void OnActionBegin(ActionEventArgs<Order> args){ if (args.RequestType.ToString() == "Add") { args.Data.OrderID = 15; //here you can dynamically assign value for OrderID column }}

Thanks for the response.Oh, what I was trying to say is TreeGrid, not Grid. There was a mistake.As you said, Grid works fine by writing values to args.Data through 'Add' RequestType of OnActionBegin.TreeGrid doesn't.It seems to be a bug in TreeGrid or something else to achieve.
