I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
View 9 RepliesI 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
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);

I have SQL Server Database Primary Data File.
I want to recover the data from that file in to my data base which has the empty tables.
I have Microsoft SQL Server Query File which contain the table structure.
I'm trying to create a Formview in ASP.net 3.5. The underlying SQL Server table does not have an identity field based Primary Key. The primary key is a 4 character user entered field. I have created the form and all looks good but I get the following error message when I try to insert a record
Could not find a row that matches the given keys in the original values stored in ViewState. Ensure that the 'keys' dictionary contains unique key values that correspond to a row returned from the previous Select operation.
I thought ViewState was supposed to resolve the issue. I have viewstate enabled on the page and the formview but that doesn't seem to make a difference.
How can I create a form view with a user-entered text field as the primary key and get the b.... thing to work?

I am trying to update the database with the edited data. However, it did not manage to read the edited data from the textbox. It returned the retrieve data that I have done in the Page_Load instead. Is there any part of the code that I have written wrongly? I did manage not to use <EditItemTemplate> in my past project and manage to update the database with the same logic.

nested repeater like this:
<asp:Repeater ID="repeaterReportListByJob" runat="server" DataSource='<%# GetReportsByJobNID(Eval(Container.DataItem, "JobNID")) %>'>
It seems my Eval(Container.DataItem, "JobNID") is not working and I assume this is because the datasource of the outer (parent) repeater is an anonymous type. So how am I supposed to access a particular field of my anonymous type?

If i mannually enter the date in db it is workingmanuall value=2014-09-30 14:00query value =2014-09-30 14:00
both are same but error is only occuring for query inserted value
I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
I have a mySQL datasource pulling back data from a query and populating a formview in edit item mode ( I only use this mode ). All is good. Business logic is such that some dates can be null. When I was putting the null or "" dates into a text box there was no problem, some users had problems with dates so I used the datepicker lite control, now the null or "" dates cause a data type conversion error stating that an empty sitrng "" cannot be cast to type date. It basically barfs here
<%# Bind("OrderDate", "{0:dddd d MMMM}") %>
This is obviously in the asp source portion of the code and there is no code in the classic VB section fo the page, it is all done by drag and drop controls and databinding.How can I fix this error and yet still allow users to put in a date, when applicable, and save the update with the new date added. eg I dont want to take out the databind if I can no longer save that field back to the db.
I've tried to override error message when input incorrect data type in input field on HTML form.For example I have the model like this.

I got this error message ,The value 'xxx' is not valid for AgeHowever, I want to change this message and try many way. There 's nothing effect this message value.
