I have a grid view and need to bind IsActive field.But from the database it comes as 1 or 0.
Error shows System.InvalidCastException: 'Specified cast is not valid.'
Grid
<asp:BoundField DataField="IsActive" HeaderText="Status">
<ItemStyle Width="200px" />
</asp:BoundField>
Code
protected void grid1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (((int)DataBinder.Eval(e.Row.DataItem, "IsActive") == 1))
{
e.Row.Cells[12].Text = "Active";
}
else
{
e.Row.Cells[12].Text = "Inactive";
}
}
}

Method 1
Try grabbing the underlying data item first and then checking for it.
protected void grid1_RowDataBound(object sender, GridViewRowEventArgs e)
{
DataRowView rowView = null;
if (e.Row.RowType == DataControlRowType.DataRow)
{
// Retrieve the underlying data item
rowView = (DataRowView)e.Row.DataItem;
// Make sure we can parse and compare what we get.
if (int.TryParse(rowView["IsActive"].ToString(), out int isActive) && isActive == 1)
{
e.Row.Cells[12].Text = "Active";
}
else
{
e.Row.Cells[12].Text = "Inactive";
}
}
}
