Add new row - can't get cell value
posted

I have a Webdatagrid, I want to auto populate data for some cells when add new row.

eg.

var grid=$find(grid_Name);

//I add new row here

var newRow  = grid.get_rows().get_row(grid.get_rows().get_length()-1); // I get a new row 

newRow.get_cellByColumnKey("myCell").set_value(myValue); // myValue != null or empty

newRow.get_cellByColumnKey("myCell").set_text(myText); // myText != empty

When I used: newRow.get_cellByColumnKey("myCell").get_value();

I received empty value(or zero if column is number). But if I don't set_text, it work.

How can I get value from new row?

Thanks & Regards!

    Hello,

     Thank you for your post!

     About your question, the approach that you follow is correct, but it depends on which event you try to get values. I have made you a sample that shows how to get old/new values (including number columns) after row is added to the WebDataGrid. If this is not helpful to you, please provide me with sample that is reproducing the issue.

    Code snippet:

    function WebDataGrid1_Editing_RowAdded(sender, eventArgs) {
                var newlyAddedRow, itemFieldValue, dataFieldValue, intFieldValue;
                newlyAddedRow = sender.get_rows().get_row(sender.get_rows().get_length() - 1);

                oldItemFieldValue = newlyAddedRow.get_cellByColumnKey("Item").get_value();
                oldDataFieldValue = newlyAddedRow.get_cellByColumnKey("Data").get_value();
                oldIntFieldValue = newlyAddedRow.get_cellByColumnKey("Int").get_value();

                newlyAddedRow.get_cellByColumnKey("Item").set_value("MyCustomValueItem");
                newlyAddedRow.get_cellByColumnKey("Data").set_value("MyCustomValueData");
                newlyAddedRow.get_cellByColumnKey("Int").set_value(0);

                newItemFieldValue = newlyAddedRow.get_cellByColumnKey("Item").get_value();
                newDataFieldValue = newlyAddedRow.get_cellByColumnKey("Data").get_value();
                newIntFieldValue = newlyAddedRow.get_cellByColumnKey("Int").get_value();

                alert("Old values [Item] = " + oldItemFieldValue + ", [Data] = " + oldDataFieldValue + ", [Int] = " + oldIntFieldValue);
                alert("New values [Item] = " + newItemFieldValue + ", [Data] = " + newDataFieldValue + ", [Int] = " + newIntFieldValue);
            }

     If you have any further questions do not hesitate to contact me.
