Consider I am using 3 fields staff id, staff name and phone no. Staff id is a primary key. I want to get a error "the record already exists" if there is already a record in the same id when i am clicking add record button. (Plz give the full coding including stored procedure for insert).
I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists.
I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made.
Does that make sense?
Using myConnectionCheck As New SqlConnection(myConnectionStringCheck) Dim myCommandCheck As New SqlCommand() myCommandCheck.Connection = myConnectionCheck myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName myConnectionCheck.Open() myCommandCheck.ExecuteNonQuery() End Using
On button click, I want to call a javascript code to check that If the entered BarCode Number in Textbox already exist in Database, then show an alert "Number already exist" else allow user to save and navigate to Default2.aspx
I can able to do the same checking on TextBox OnTextChanged event using c# code, as below:
protected void TextChanged(object sender, EventArgs e) { TextBox txtbarcode = fvIPRForm.FindControl("txtbarcodenumber") as TextBox; if (txtbarcode.Text.Length > 0 && txtbarcode.Text.Length < 11) { string error = "The Barcode Number " + txtbarcode.Text + " is invalid, the barcode length must be 11 character."; ScriptManager.RegisterStartupScript(this, typeof(string), "Successful", "alert('" + error + "');", true);
[Code] ....
Here, IPRRequest is the class/.dll file name and IsValidBarcodeTest is a function defined in the class file
But same checking I tried using the c# code on button's OnClick="btnSave_Click" event, but dont know why this event is not firing, I guess due to CommandArgument on button, but I am not sure.
Dim Result As New DataTable DataAdapter.Fill(Result) 'bind data to visible surname/name grid If Result.Rows.Count = 0 Then NoInputBottom.Text = "No Results. Please widen your search criteria and try again" NoInputTop.Text = "No Results. Please widen your search criteria and try again" Else GV.DataSource = Result GV.DataBind() End If
I have also tried moving the check to the gridview like so:
If GV.Columns.Count = 0 Then NoInputBottom.Text = "No Options Selected: Please select your search criteria and try again" NoInputTop.Text = "No Options Selected: Please select your search criteria and try again" End If
When I run the code. the noinput labels do not have value, the null check seems to be failing? how to display a message if the search returned no reults.

I have a .Net 4 Chart Control bound to stored proc. For some customer selected queries the chart will be empty. I would like to display a "No data" message in the empty charting area so customers understand why the chart is empty. I haven't been able to find any information about how to do this.
How do I display results from my database on a gridview based on the selected row of another gridview.
For example, I have a e-shop web app and I have a product categories table in my database displaying the data on a gridview.
I want to be able to click on the select button on each row and use that event to populate another gridview based on the ID of the product category that is clicked. E.g say the 'CDs' row is clicked, another gridview shows all the different CDs.
As a result, I need the select(sql) statement for the second table to be dynamic based on what the user clicks.
supose i have one table nd there are many records in table .this table access by many usewhen any user inserted record in database then show message in popup boxnd this message show in all users
sometimes learning asp.net feels so heavy handed compared to some of the general purpose scripting languages like php. for examples, all i want to do is create a sql connection that pulls a row count and displays that number. I don't need a grid, list, detail page, etc., nothing this heavy... a simply query that will display a simple bit of text. for the life of me I can't figure out how to do it. Using these controls, I'm not in the code behind with the query, so I wouldn't attach this to a label (or would i), and there's nothing i see in the toolbox that does what i want. Perhaps i'm too accustomed to php but it feels like with asp.net, major things are simple, and simple things are hard.
