Inserting records rfrom gridview

Question

Hi, I am using gridview footer to insert records into the database. I need to insert startDate(datetime datatype), endDate(datatype),amount(float)as well as other varchar data.
This is my database.cs:

 //method to create contracts
public bool 
Insert_ContractRecords(string contractID, string empName, SqlDateTime startDate, 
SqlDateTime endDate, float amount, string vendorbrn, string name, string 
products, string rfpRef, string projectTitle, string alert)
{
SqlCommand 
cmd_ContractList = new SqlCommand();

cmd_ContractList.CommandText = 
"[VRM].[INSERT_ContractRecords]";
cmd_ContractList.CommandType = 
CommandType.StoredProcedure;
cmd_ContractList.Parameters.Clear();


SqlParameter 
sqlParaContractID = new SqlParameter("@contractID", SqlDbType.VarChar, 
10);//ContractID
sqlParaContractID.Value = 
contractID;
cmd_ContractList.Parameters.Add(sqlParaContractID);

SqlParameter 
sqlParaEmpName = new SqlParameter("@empName", SqlDbType.VarChar, 140);//Owner 
Name aka Employee Name
sqlParaEmpName.Value = 
formatWildCard(empName);
cmd_ContractList.Parameters.Add(sqlParaEmpName);


SqlParameter 
sqlParaStartDate = new SqlParameter("@startDate", SqlDbType.DateTime); 
//Contract Start DATE
sqlParaStartDate.Value = 
startDate;
cmd_ContractList.Parameters.Add(sqlParaStartDate);

SqlParameter 
sqlParaEndDate = new SqlParameter("@endDate", SqlDbType.DateTime); //Contract 
End date
sqlParaEndDate.Value = 
endDate;
cmd_ContractList.Parameters.Add(sqlParaEndDate);


SqlParameter 
sqlParaAmount = new SqlParameter("@amount", SqlDbType.Float); 
//amount
sqlParaAmount.Value = 
amount;
cmd_ContractList.Parameters.Add(sqlParaAmount);


SqlParameter 
sqlParaVendorBRN = new SqlParameter("@vendorbrn", SqlDbType.VarChar, 
10);//Vendor BRN
sqlParaVendorBRN.Value = 
vendorbrn;
cmd_ContractList.Parameters.Add(sqlParaVendorBRN);

SqlParameter 
sqlParaVendorName = new SqlParameter("@name", SqlDbType.VarChar, 140);//Vendor 
Name
sqlParaVendorName.Value = 
name;
cmd_ContractList.Parameters.Add(sqlParaVendorName);

SqlParameter 
sqlParaProducts = new SqlParameter("@products", SqlDbType.VarChar, 
1000);//Products/Services provided by vendor
sqlParaProducts.Value = 
products;
cmd_ContractList.Parameters.Add(sqlParaProducts);


SqlParameter 
sqlParaRFPRef = new SqlParameter("@rfpRef", SqlDbType.VarChar, 
50);//RFPRef
sqlParaRFPRef.Value = 
rfpRef;
cmd_ContractList.Parameters.Add(sqlParaRFPRef);

SqlParameter 
sqlParaProjectTitle = new SqlParameter("@projectTitle", SqlDbType.VarChar, 
50);//Project Title
sqlParaProjectTitle.Value = 
projectTitle;
cmd_ContractList.Parameters.Add(sqlParaProjectTitle);


SqlParameter 
sqlParaAlert = new SqlParameter("@alert", SqlDbType.VarChar, 
1);//Alert
sqlParaAlert.Value = 
alert;
cmd_ContractList.Parameters.Add(sqlParaAlert);


return 
executeNotQuery(cmd_ContractList);

}

This is my stored procedure:

 

ALTER PROCEDURE 
[VRM].[INSERT_ContractRecords]
(

@contractID varchar(10), 
@empName 
varchar(140),
@startDate datetime,
@endDate datetime,
@amount 
float,
@vendorbrn varchar(10), 
@name varchar(140), 
@products 
varchar(1000), 
@rfpRef varchar(50), 
@projectTitle varchar(50), 

@alert varchar(1), 
@templateID 
varchar(10)

)




AS

BEGIN

INSERT INTO 
VRM.ContractManagement VALUES( @contractID , @empName,@startDate, 
@endDate,@amount,@vendorbrn,@name,@products,@rfpRef,@projectTitle,@alert,@templateID)

END

This is my business logic:

 

protected void gvContract_RowCommand(object sender, 
GridViewCommandEventArgs e)
{
if 
(e.CommandName.Equals("AddNew"))
{




TextBox txtContractID = 
(TextBox)gvContract.FooterRow.FindControl("txtContractID");
TextBox 
txtEmpName = 
(TextBox)gvContract.FooterRow.FindControl("ttxtEmpName");
TextBox 
txtStartDate = 
(TextBox)gvContract.FooterRow.FindControl("txtstartDate");
TextBox txtEndDate 
= (TextBox)gvContract.FooterRow.FindControl("txtEndDate");
TextBox txtAmount 
= (TextBox)gvContract.FooterRow.FindControl("txtEndDate");
TextBox 
txtVendorBRN = 
(TextBox)gvContract.FooterRow.FindControl("txtVendorBRN");
TextBox txtName = 
(TextBox)gvContract.FooterRow.FindControl("txtName ");
TextBox txtProducts = 
(TextBox)gvContract.FooterRow.FindControl("txtProducts ");
TextBox txtRef = 
(TextBox)gvContract.FooterRow.FindControl("txtRef");
TextBox txtProj = 
(TextBox)gvContract.FooterRow.FindControl("txtProj");
TextBox txtAlert = 
(TextBox)gvContract.FooterRow.FindControl("txtProj");



vrmdb.Insert_ContractRecords(txtContractID.Text, 
txtEmpName.Text, txtStartDate.Text, txtEndDate.Text, txtAmount.Text, 
txtVendorBRN.Text, txtName.Text, txtProducts.Text, txtRef.Text, txtProj.Text, 
txtAlert.Text);



BindGrid(true);
Response.Redirect("ContractThreeGridView.aspx");

}
}

However there is an error indicating:
