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;
cmd.Parameters.AddWithValue("@trainerId",trainerID);

Web Forms :: Class Method Error "Arithmetic Operation Resulted In An Overflow"

Sep 28, 2010

I have a class that runs calculations on numbers and populates the results to my SQL database. My code behind page instantiates the class object, and in a loop it makes use of the method five times (once per loop). Essentially, my code behind collects the information from controls and passes the information to the class method for processing. The method works just fine most of the time.

On one of the iterations I get a error before the code even gets to the class. The error is, "Arithmetic operation resulted in an overflow." What strikes me as odd is that while stepping through the code, the loop crashes with that error before getting to the class that runs the calculations. Additionally, no arethmetic operations are performed on the form's code-behind page (which calls the method). I even put a break-point on the class constructor but the code crashed before reaching that constructor.

The information being sent is the results of matches from a sporting event. As a troubleshooting measure I changed the order of the matches by deleting them an re-entering them into the database in a different order. Again only this one particular match crashed. Here is the code that crashes:

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

DataSource Controls :: Cannot Evaluate Expression Error After Converting VS 2003 Web Application To VS 2008?

Jul 8, 2010

I recently converted a web application of ours to VS 2008 so that we could upgrade to .net 3.51 framework.

I have been making some changes to the layout, to take advantage of ajax and minimize the amout of data needing to be loaded and the number of postbacks processed.

The problem I am having is when I try to save the data.

The page postback calls a local Sub which reads the form data into local variables and then passes these variables to our assembly.

The primary assembly has 70 parameters which are used to populate one of the tables in our database.

So I have 70 local variables just for this call plus a variable reference to the output of the assembly which contains a property for each of the columns in the associated database record.

There are some additional assemblies called to update other tables so, in all there are 121 locally defined variables in this sub.

Bear in mind that this sub is called from the page load event which has 93 of it's own locally declared variables.

Here is what is happening, when I run the code I am using cdate() to convert the value of a text box to datetime and pass it to my assembly. When doing so it throws a conversion error.

So I created a local datetime variable and converted the value of the control to the datetime and passed the variable to the assembly.

No more error, but the proc did not save the data as it was supposed to.

What I noticed in debugging, on the locals tab, is that every local datetime variable displayed the following message:

Cannot evaluate expression because we are stopped in a place where garbage collection is impossible, possibly because the code of the current method may be optimized

I also noticed that on the watch window the same message would display if I attempted to reference any of the datetime controls on the form.

There are only 3 variables and 3 datetime controls that appear to be affected. the controls are all html input boxes. Every other variable and control on the form behaves normally and I can see their values while debugging, it is just these six that are exhibiting the problem, whats more is that they are not new controls to the form.

Forms Data Controls :: Gridview Sorting Stack Overflow Error?

May 10, 2010

This is very frustraiting because I have read a thousand posts on this and nothing works. I have a gridview which is programatically bound to a dataset which is created from dataset.readxml(xdocument.createreader). The table gets created without issue.

I have allow sorting set to true. when i click the sorting linkbutton I get the event handler error. So i create an empty event handler and that doesn't give me an error but also accomplishes nothing. So I searched and searched and found that i need to call the gridview.sort method to programmatically sort in the event handler. So when i do this

GridView1.Sort(expression, SortDirection.Ascending)

as seen in

[URL]

i get stackoverflow error. it creates an infinate loop. none of the 20 or so posts out there seem to answer how to handle this. They say that this method is the way to call sorting.

below is my event handler

[Code]....

the behaviour is that the event handler fires and executes to the sorting line which in turn refires the event handler.
