how to do aggregation and sums in gridview from textboxs required examples
ex: while trading in stock market it was chnaging dynamically how it was working explain with examples
I want to create a gridview that all the values are on textboxs.For exemple when you use the AutoGenerateEditButton... The row where you clicked will became editable using textboxs with the data.Well what I need is that ALL the data of the Gridview will became editable as soon as you click a button.Also i'm using AutoGenerateColumns="True" because I don't know how many TemplateField I will have. (well in fact you can know how many you will need if you somehow cicle through the dataset that will populate the gridview)
View 2 RepliesI have a gridview in one page and textbox in an other, I want to pass my gridview row into textboxs of the other page.
View 3 RepliesIs it possible to make it so that a particular field in my gridview is made mandatory based on a session variable and the value of a dropdwnlist located outside of the grid itself...so
If Session("location") = "HOME" and DropDownList3.SelectedValue = ("5") then
"fieldinmygridview" cannot be null (i.e is required)
end if
i am using the required field validation and Reqularexpressioncontrol in gridview. Fields are in the gridview are in template, but only the edit button it is not templeted, this edit buton is of type Imagebutton and same goes with canel and update.
1_ Do i have to use the Templeted fields for edit/cancel/ and update as well in order to use the validation?
2_Validaiotn should only work when user clicks on the Update button, it should not trigger when cancel button fired.

now i have One TextBox and four radio button like 1.rbFirstName,2.rbLastName,3.rbAge,4.rbDatemy requirment is if i select radiobutton first rbFirstname and i will enter a text into textbox than ONKEYUP filter the gridview data and show only those row where data is match in first coloum"First Name" and hide the rest of rows...same required for radiobutton 2,3 and 4 respectively in gridview 2nd ,3rd and 4th coloum....i need this solution in javascript or Jquery but i dont want reload the page...
in my module there are data of students for H.S.C., C.E.T, AND H.S.C+C.E.T. so when i run the gridview page all the data of all streams together is displayed so i sort the data using a dropdownlist...means if 1 select the H.S.C in dropdownlist only the H.S.C students are being displayed.so the problem is when i sort the data by selecting a stream in dropdownlist at that time the error message of required field validator is displayed...
1) I wil select the stream from Dropdownlist and click the "sort button"
2) After the data is been sorted and i will enter the values in the TextBox and if i'll miss any of the textbox blank and i click on the "submit button" after dat the error should be displayed
as "Required".
I have a scenario which is there's a gridview with remove button and also a textbox.
Example:
The value of textbox is 2, and rows of gridview is 5 so the rows from 3-5 will be highlighted. And if the user removed the first row, the highlight should be follow. The highlighted row now is 3-4.
The remove button is jquery also.
See photo for more clarifications ....
in my website there is a module in which i m fetching the data of present students in the gridview and i m entering there marks in the gridview textbox column (created by using item template)...I want to add required field validation to the textbox columns so that after clicking the submit button there should be an error message displayed if any of the textbox is empty...
View 1 RepliesI am working on a legacy application. It uses custom MVC framework and Windows Communication Framework service to bridge the Presentation layer with the rest of the application (i'll call this AppServer).
Every Entity in the AppServer inherits from BaseEntity which contains the method:
[Code]....
As you can see:
if the personObject was not null, but the ContactAddress was, [which is exactly what happens in the construction of a PersonObject in the event that no contact details are provided (hence they are not present in the HashTable and dont get created)] then the code will fail with a null reference exception.
SO:
Is there a fundamental flaw in the way that objects are getting created? It would be easy to point the finger in this direction, however, im sure there must have been some reason for the original architect to choose not to instantiate an empty ContactAddress object every time a Person object is referenced - EG if in a particular Presention->AppServer Request/Response cycle we only want a person's login details - we wouldn't care about the ContactDetails.
FINALLY MY QUESTION:
Is there a clean way to check for null objects within an aggregation, without doing something like:
if(Parent!=null)
if(Parent.child!= null)
if(Parent.child.child != null)
It just looks messy and it seems such a common problem, im sure there would be a better way of doing things.
here i have 5 text boxs for 4 text boxs i kept RequiredFieldValidator's and for next text box i am return javascript function....

On my asp.net page i use a multiline textbox to let users store some text... Sometimes users need to copy/paste email messages from outlook into the textbox. When they do that i looks like the textboxs add extra newlines?? How can i prevent this? Can i intercept a paste into a textbox and remove unwanted end of lines?

I have some controls on the asp.net page that can be required on certain senario and can be not required on others.
So we enable/disable them dinamaically depending on the current transactions.
Now I am thinking of a way where I can check the required field by Javascript on the click event of save button. Remember control not be required at all time.
I make one datalist and put data in it and add one button for selection. When you click the button and you can select the necessary data.
The following is my code:
Protected Sub ImageButton20_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImageButton20.Click
Dim myConnection As SqlConnection
Dim myCommand As SqlDataAdapter ' Create a connection to the "pubs" SQL database located on the
' local computer.
myConnection = New SqlConnection("server=localhost;" _
& "database=pubs;Trusted_Connection=Yes")
' Connect to the SQL database using a SQL SELECT query to get all
' the data from the "Titles" table.
myCommand = New SqlDataAdapter("SELECT * FROM Product Photos WHERE Product Name= FOOD ", myConnection)
' Create and fill a DataSet.
Dim ds As DataSet = New DataSet()
myCommand.Fill(ds)
' Bind MyDataList to the DataSet. MyDataList is the ID for
' the DataList control in the HTML section of the page.
DataList1.DataSource = ds
DataList1.DataBind()
End Sub
However it is still not workable. Who can fix it?
