best way to check if a row already exists in ui5 before insertion

Hi Guys,

what will be the best way to check if the row is already exists in UI5 table before insetion a new record in ui5 table.

I thought i will check the record which i'm going to insert by doing oModel.Read and if the record exists then give message to user if not insert a new record.

Can you share your views or the methods?

    Hi Anurag,

    My suggestion is to use model to check the duplicate which is associate with the table.

    We have function in javascript.

    oTableModel = this.getModel("TableModel");
    var iIndex = {

    It will return true, if that model already contains same id.

    Using this you can avoid duplicated in your table.

    For the data in a view control ex: table, we can either check for the data through the control id or through the model bound to the control.

    I would suggest, checking with the model data, as based on the entries of the model the rows are created in the control.

    If the model is empty, then there are no rows in the table.

    You can check with the key of your entry. If your table is bound to OData model, then you can check if the entry exist with that code :

    var entry = myOdataModel.getProperty("/myService(key1='value1',key2='value2')");

    The entry variable will tell you if there is something or not.
