int data type is not working as parameter

I have a GridView in which I have check box as Item Template, and I am updating the GridView when check box is changed. Here is my GridView code:

<Columns>
    <telerik:GridTemplateColumn>
    <ItemTemplate>
        <asp:CheckBox ID="chkcelar" runat="server" Text="Clear" OnCheckedChanged="chkclearchng" AutoPostBack="true"/>
    </ItemTemplate>
    </telerik:GridTemplateColumn>
        <telerik:GridBoundColumn DataField="BPV_NUM" DataType="System.Int64"
            DefaultInsertValue="" HeaderText="BPV No" SortExpression="BPV_NUM" 
            UniqueName="BPV_NUM">
        </telerik:GridBoundColumn>
</Columns>

and here is the c# code through which I am updating grid view

protected void chkclearchng(object sender, EventArgs e)
    {
        OleDbConnection con = new OleDbConnection("Data Source=sml; User ID=sml; Password=sml; provider=OraOLEDB.Oracle");
        OleDbCommand cmd  = new OleDbCommand();
        CheckBox chkcelar = ((CheckBox)(sender));
        GridDataItem  row = ((GridDataItem)(chkcelar.NamingContainer));
        long bpvnum = row.Cells[1].Text;

        if (chkcelar.Checked ) {
            cmd.CommandText = @"update sml.FND_01_11@wbg set CLR_FLG=1, CLR_DTE=sysdate where bpv_num=:bpv_num and bpv_dte=:bpv_dte";
        }
        else {
            cmd.CommandText = @"update sml.FND_01_11@wbg set CLR_FLG=0, CLR_DTE=sysdate where bpv_num=:bpv_num and bpv_dte=:bpv_dte";
        }
        cmd.CommandType = CommandType.Text;
        cmd.Connection  = con;

        cmd.Parameters.Add(":bpv_num",OleDbType.BigInt).Value = bpvnum;
        cmd.Parameters.Add(":bpv_dte",OleDbType.Date).Value   = RadComboBox1.SelectedValue;

        con.Open();
        cmd.ExecuteNonQuery();
        con.Close(); 

    }

The problem is that when I change the check box this error appears:

Input string was not in a correct format.

Can anyone tell what may be the issue and how can I resolve it?

The issue in your code is because of the wrong type conversion from "string" to "OleDbType.Date". So replace the following code 

cmd.Parameters.Add(":bpv_dte",OleDbType.Date).Value   = RadComboBox1.SelectedValue;

with the following code

cmd.Parameters.Add(New OleDb.OleDbParameter("@bpv_dte", OleDb.OleDbType.Date));
cmd.Parameters("@bpv_dte").Value = RadComboBox1.SelectedValue.ToString("d");

Also make sure to convert all types correctly to OleDbType if there are more lines used for insertion.

Using Quick window check what is the vaule returns on "row.Cells[1].Text".

May be you should use

long bpvnum = long.Parse(row.Cells[1].Text);

if doesn'T work then on this line

cmd.Parameters.Add(":bpv_dte",OleDbType.Date).Value   = RadComboBox1.SelectedValue

You need parameter type OleDbType.Date but you are assigning RadComboBox1.SelectedValue

so you need to convert your 

RadComboBox1.SelectedValue to OleDbType.Date

or you should simply use DateTimePicker instead of ComboBox

Change your code like this:

    protected void chkclearchng(object sender, EventArgs e)
    {
        using (OleDbConnection con = new OleDbConnection("Data Source=sml; User ID=sml; Password=sml; provider=OraOLEDB.Oracle"))
        {
            con.Open();
            using (OleDbCommand cmd = new OleDbCommand(null, con))
            {
                CheckBox chkcelar = ((CheckBox)(sender));
                GridDataItem row = ((GridDataItem)(chkcelar.NamingContainer));
                long bpvnum = Convert.ToInt64(row.Cells[1].Text);
                if (chkcelar.Checked)
                {
                    cmd.CommandText = @"update sml.FND_01_11@wbg set CLR_FLG=1, CLR_DTE=sysdate where bpv_num=@bpv_num and bpv_dte=@bpv_dte";
                }
                else
                {
                    cmd.CommandText = @"update sml.FND_01_11@wbg set CLR_FLG=0, CLR_DTE=sysdate where bpv_num=@bpv_num and bpv_dte=@bpv_dte";
                }
                cmd.Parameters.Add(new OleDbParameter("@bpv_num", bpvnum));
                cmd.Parameters.Add(new OleDbParameter("@bpv_dte", Convert.ToDateTime(RadComboBox1.SelectedValue)));
                cmd.ExecuteNonQuery();
            }
        }
    }
