Here I am generating list box dynamically. But the problem is that exception is throwing in case texbox in <listcell><textbox value="@bind(item[columnInfo.value])" hflex="1"/></listcell>. Exception is throwing only in textbox. But the code value="@bind(item[columnInfo.value])" is working fine for datebox, checkbox etc.
