This is just an example above but i believe it shows what i am trying to do, there is no calculated column in the database so i can not bind to that directly, and i can not just add the column to the data as its not in my permissions. So how do "Bind" the value of two columns multiplied together to a third text box?
If i have 55 checkboxes with different text 1,2,3,4 and so on ....and a textbox where it display how many no. of checkboxes checked i want to multiply the multiple selected checkbox text with how many checkboxes are checked in other textbox i want to do this using vb.net,asp.net
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.
I have a Gridview with 12 columns, Jan, Feb...Dec.
I have a textbox value that could be 1, 2,...12
I want if textbox value is 7, then column Aug-Dec in Gridview is editable when in update mode and the column in Jan-Jul is not updatable (eg make it label instead of textbox).
i have one grid which have 5 columns 1 for subject,2,3,4 for marks which have textbox to insert obtained marks,and last column have one lable to display total of (2+3+4),now i want total value on textbox event,when user enter any value to any column of textbox i need to display total of all three columns in total column.
I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns() { // The first column to begin to insert the columns in the GridView int columnIndex = 5; BoundField aoColumn = new BoundField(); aoColumn.HeaderText = "New Column 1"; gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback gvMyGrid.Columns.Add(aoColumn); // works fine columnIndex++; foreach (MyEntity my in _myEntityCollection) { BoundField myColumn = new BoundField(); myColumn.HeaderText = String.Format("{0:d}", my.StartDate); gvMyGrid.Columns.Insert(columnIndex, myColumn); columnIndex++; } }
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.
in asp.net page user able to select gridview Columns, and it will hide remaining columns and that selection done by check box with column list bellow is Image link , what exactly I am looking for [URL] it look bellow after selection of column done [URL]
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
I apologize for the odd title. I've been trying to figure out how to do this and can't quite put it into words. Basically, I need to try to display a GridView with a whole bunch of columns (37 in one case) in two "rows" of columns. More or less.
So instead of this:
Column1 Column2 Column3 Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data Data
I'd like something like this:
Column1 Column2 Column3 Data Data Data Data Data Data Data Data Data
Column4 Column5 Column6 Data Data Data Data Data Data Data Data Data
As in the example there can be multiple rows returned which all need to be displayed. I'm trying to stop a very large horizontal scroll bar being required. I've been searching as much as I can but haven't found anything that fits what I'm looking for.
I have two int in my applicantion and I want multiply and share by 100. This number can be like 7,5 but my decimal result member always save just 7.how can I deal with this question?

I would like to multiply the values from two text boxes (txtBox1 should contain an Integer value, txtBox2 should contain a Float value) and place the result in a third text box. My code is below, but it doesn't work. The javascript function is called, otherwise it fails.
I'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
I'm at the end of a project and have hit a wall. I'm pretty unfamiliar with VB so this is why I've left this piece of the project for last.
I have a popup window in which I pass some values via QueryString. I want to be able to pull them into my application and do some math on them and then write them out to my aspx page. The problem is I don't know where/how to begin. I've searched around the asp.net boards, but can't seem to find any good starting point.
I'm reading in some dollar amounts, a percentage and an Id that I'll use to pull a payment schedule (number of payments). I'm trying to get at a payment breakdown. I was thinking of writing it Something like this:
