How to add two text box values and equating with other textbox and disabling the button.
I have 3 textboxes shipQty1, shipQty2,Orderqty and a button i.e. CustomerReport.I want disable the CustomerReport button when this expression succeeded shipQty1+shipQty2=Orderqty. if orderQty is equal to ship1 and ship2 then CustomerReport button should be disabled.
I've done a bit of development with C# applications but not much with ASP.Net so if this is a trivial issue. I have a webform that has textboxes for password, phone number and a listbox for a provider. When I load up the webpage, I populate with the textboxes and listbox with selections from my SQL database. This works correctly. Then I allow the user to change data in any of controls. In the event that is triggered by the Save button, the values in the textboxes and listbox are the data values that were populated during the loading of the page, not what the user has typed in.
What am I doing wrong? I've attached my 2 pages of code.
i have 2 template field columns time and total_time in a gridview.. time column has a label in the item template and a textbox in th edit item template..
similarly, total_time has a label in the item template and a textbox in the edit item templte..
what i need is, when the user enters a value in the time textbox,it must get updated in the total_time textbox.. and on edit,when the user changes the value of the time textbox ,dis value must be ADDED to the total_time textbox.. both should be displayed in the label also..
How Can I retrieve values from TextBox before RowUpdating function is fired? I have GridView with update panel which is sorted by two dropdownlists and I need autopostabacks to filter and bind gridview. Now I want to update row in my gridview but I can't get values from controls I'm getting old values from database. Do you the way that I can use values from controls before updating the row?
In FormView (insert) I have a number of textboxes into which number will be inputted. I need all these textboxes to add up and display the total in a Label which I can then insert into the database with all the individual values. I expected this to be a simple thing... Then it appears that the best way to do this is to use javascript, which I have never used! SO this is my attempt which is a combination of things I found on the net, In the head (Clientapp is the name of my form)
<script type="text/javascript" language="javascript"> function Add1(Clientapp) { var a, b, c; a = document.Clientapp.BondRepaymentTextBox.Value; b = document.Clientapp.PropertyRentalTextBox.Value; c = eval(a) + eval(b); document.Clientapp.ceTotalTextBox.Value = c; } </script>
Code behind on Page Load
PropertyRentalTextBox.Attributes["onchange"] = "javascript: Changed( this );";
I want to validate a textbox that only a numeric currency value can be put into it, for example 0.00. I thought the following code was correct but it doesnt seem to wrk, its causing an error on my page and when I remove it the page is fine, it doesn't actually give exact details of the error on the page just says "syntax error" in the browser that is all.
I have generated dynamic text boxes for each table row there are 6 text boxes
1. For the first two text boxes the values given by the user should be in valid range(this range comes from the database).User is allowed to enter the value within that specified values only. How to achieve this? I have taken drop down lists but if the values in drop down increases selecting required value is tedious to the user.. (if it is having 1000 values) and while I am retrieving the values I have written query such as Null values ignored. But I am getting NULL values in the dropdown here is the code what I have written,
(Database is Oracle) If Not (OledbCmd.Equals(String.Empty) Or OledbCmd Is Nothing) Then OledbDA.SelectCommand = OledbCmd OledbDA.Fill(ds, "textDB") dt = ds.Tables("testDb") If (dt.Rows.Count > 0) Then ddlist.DataSource = dt If UCase(s) = "NUMBER" Then ddlist.DataValueField = "num" ElseIf UCase(s) = "NAME" Then ddlist.DataValueField ="name" End If ddlist.DataBind() ddlist.Items.Insert(0, "Select") ddlist.SelectedIndex = 0 Else ddlist.Items.Insert(0,"Norecords") End If End If
2. In the rows generated when user presses functional key F3 then the values of the above row(previous row) have to be copied in present row. similarly for F4 column copying. This I achieved through the Java script. But I have many forms requirement is same. where as text boxes id differ. how can I generalize the One function to work for all forms. I wrote as like this.
I have a dropdownlist which display the price of products which is retrive from database, how do i mulitply if the user entered the quantity in the textbox. I keep getting error input string was not in a correct format.
What I want to happen is, I will populate or load the patient Name into TextBox. If the patient are 20, the page will dynamically create 20 textboxes to display the patient name..And when I click save, Changes will be save base on the input on textbox..
I have a remarks column which allows null values.. When i try to load a selected row from gridview
Which has nothing in remarks..I get displayed in the textbox where i need to load the remarks.. I do not want to be displayed.. If nothing is there in that remarks column textbox should be blank.. How do i do this?
