Data Controls :: Saving DropDownList Value To Database - Error Converting Data Type Nvarchar To Int

May 7, 2015

I am using  a  viewstate to store the company Ids and splitting at hyphen.

protected void onCompanychange(object sender, EventArgs e) {
ViewState["companyID"] += companydropdown.SelectedValue + "-";
String companyids = ViewState["companyID"].ToString();
string pattern = "-";
company_array = Regex.Split(companyids, pattern);
company_length = company_array.Length;

Company array is a string array  where i have stored the company ids

the problem is company_array[0] has the initial value of the dropdownlist(company) --select company which is why m getting the error(cannot convert data type nvarchar to int) .  I have used the same logic in many places in my project it did not give any error.

int count = 0;
company_length = company_length - 1;
while (count < GridView3.Rows.Count && compid_counter < company_length ) {
cmd = new SqlCommand("insertWorkDetais", conn);
cmd.CommandType = CommandType.StoredProcedure;

[Code] .....

Syntax Error Converting The Nvarchar Value To A Column Of Data Type Int?

May 5, 2010

I have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db.

I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this:

"Select things From MBA_EOI Where level = 1"

When I run the select I get the following error:

Syntax error converting the nvarchar value '1,2,3,4,5,6,7,8,9' to a column of data type int.

I was under the impression that I was dealing with an Nvarchar field and the selected value as string, where does the int conversion come in?

p.s I have also tried Level.SelectedItem.ToString

SQL Server :: Convert Label.text To Int / Error Conversion Failed When Converting The Nvarchar Value 'Label' To Data Type Int.'?

Jul 14, 2010

I have been messing about with this for hours surely this should be an easy task ....... I have a stored procedured that creates a invoice on a Quotetable one of the parameters is a output parameter Invoice Number this is passed to a label. (Label1) This works great.

I then need to add items to the invoice on a item table so my next stored procedure should take the value of Label1 and update the foreign key quotenumber on the itemtable with the value from label1.

On the aspx page I have a small section for a gridview which shows the current quote with however many items on it using the control


On the ASP page the control for @Quotenumber = Label1 but I get the following error

'Conversion failed when converting the nvarchar value 'Label' to data type int.'
