        {
            ds_CompanyDetails.UpdateParameters.Add("@CompanyName",txtCompanyName.Text);
            ds_CompanyDetails.UpdateParameters.Clear();
            ds_CompanyDetails.UpdateParameters.Add("@CompanyDetailId", lblId.Text);
            ds_CompanyDetails.UpdateParameters.Clear();
            ds_CompanyDetails.Update();
            ds_CompanyDetails.DataBind();

But why? What exactly you want to achieve?

Because you keep clearing the parameters maybe?
And why do you try to declare variables in the SQL statement?

I can see two problems...
1. Your SQL is written in a single line and no separators (like ; ) in between, so it should lead to some errors on the SQL side...Try something like this:

SQL

UpdateCommand="DECLARE @CompanyName NVARCHAR(50); DECLARE @CompanyDetailId INT; UPDATE CompanyDetail SET CompanyName=@CompanyName WHERE CompanyDetailId=@CompanyDetailId;"

2. You clear all the parameters immediately after you init them...Change your code like this:

C#

ds_CompanyDetails.UpdateParameters.Clear();
ds_CompanyDetails.UpdateParameters.Add("@CompanyName",txtCompanyName.Text);
ds_CompanyDetails.UpdateParameters.Add("@CompanyDetailId", lblId.Text);
