Hi Vijay,
Is this correct?
var oInput = new sap.ui.commons.DropdownBox("ddlb_matnr");
var oItemTemplate = new sap.ui.core.ListItem();
oItemTemplate.bindProperty("key", "Matnr");
oItemTemplate.bindProperty("text", "Description);
oInput.bindItems("/sap/opu/odata/sap/Z_MATNR_F4_SRV/materialSet", oItemTemplate, null, "'');
This should work ?
Let me know?
