Asp.net - GridView For Each - Displays Items Details
May 2, 2009
I have a gridview that displays items details, I added two template fields one is a checkbox and the other is a textboc, what I want is simply to check all the items the customer wants to buy, and write down the quantity in the textbox, when I click on a button, I should check all rows in the gridview and when the checkbox is Checked then I should compare the value in the textbox with the value in a databound field of the gridview called Quantity and then carry on my order function...
I am sure this is not a unique problem, but I am drawing a blank (Monday morning) on how to fix it.On my Nav menu, user opens a page with a DDL, selects a record from drop down which opens up a single line in a Gridview with a few fields displayed. User can click Edit and Update two fields or of course Cancel, or select another record from the drop down which displays the new record in the Gridview.All this works fine.Issue is when the user goes to Nav menu and goes to another page then comes back to the first page, the last record that was being viewed is still displayed in the Gridview instead of showing only the DDL and waiting for a selection. Its as if the Page Load event does not fire again (In fact it does not). I need it to fire as an initial load, in order for the 'If Not ISPostback Then' logic to properly fire.
I have a Table. In Form1 i have a TableDataGridView.
I like with double click in a Row of TableDataGridView, open a new form (Form2) with details view (of the same table) but textboxes filled by clicked row.
I Know the event
Private Sub Table1DataGridView_CellDoubleClick But i cant find code for that what i need.
I was assigned a task so as to bind the user related data into a grid view on user login. I have got two web pages, one of which contains Login and authentication information. This goes fine. When user was redirected to second page, I need to provide a GridView control where user details should be automatically updated in grid view control in the back ground.I have three different fields which were saved in sql table. particular user details need to be retrieved from the sql table on user login and bind the data to grid view automatically.
How to show pop up menu from database in gridview on each gridview row items ?Example of this is : http:[url].....Move your cursor to Departure time and arrival time...a want this type of popup in gridview items....which fetch entries from database..
I'm creating a program for school coursework which serves as an online ordering system for a local carry-out. I need to create a menu interface which displays all the items, where the user clicks on their choice, enters the quantity desired and then its added to a list box.
The dropdown box displays all the items previously added to that column.
I want the user to be able to enter a new value OR just pick a previous value from the dropdown list. (This is when inserting a new row)
Problem:
Whenever I enter a value, it jumps around in my table like its on acid or something. Whenever I select a value from the list, it takes me to the line in which the value was originally entered.
I've have a problem, this sub works just fine adding items into a listview.. Some reason they forecolor of items / subitems wont change in view.details mode, it seems to work in other views but not details, and details is what i need as you can see I'm even using Item.UseItemStyleForSubItems = False
I am looking to be able to add items to a combox in a gridview at runtime. The only code that I have found is for an editable datagrid combobox not one that items can be added on runtime. Is anyone now of a free datagridview control that does this?
I am creating a web application in ASP.net/VB.NET and I have an issue with the gridview.Currently, I have the gridview populated with data from the DB and I've also coded the update button to allow the user edit any necessary information through a form that pops up.[URL]...
What I'd like to do, if possible, is add a button to the two right columns(I already put one in the Dock Out Time column) which will be invisible if the column is set or will set the current time to the column. Setting the time for those two columns is already handled through the update form, but my supervisor asked me to try and see if this was possible.
Those two Time columns are Templatefields(since I format the display time from what is actually in the DB) and I added an asp button in the ItemTemplate for that Set Button in the picture.Is this even possible to do and if so, how would I access this button in the code behind so I can add functionality(setting the time and hiding it if the column is not null)If it's not really possible to have two items like this in a templatefield I can just make 2 extra columns for these buttons but I think this would look much cleaner.
if booking closed column values is equal or more than textbox1 text then the book button in gridview will be disabled for each gridview item whose booking closed time is greater and equal to textbox1 time ..
I am trying to an ImageUrl to an image in a Template Field in GridView but keep getting the error: Object reference not set to an instance of an object. on this line: Dim imagePath As String = rowView("image_path") I've never done this before on a GridView but had it working on a ListView.
I want to show items in my gridview as a 5 across and a 5 down display - I already have the query pulling only 25 records per a page but cant seem to make the gridview do what I want
Example:- record 1 : record 2 : record 3 : record 4 : record 5 record 6 : record 7 : record 8 : record 9 : record 10 etc ...........................................
I would like to show different values in a dropdownlist, while editing a gridview, depending on which user is logged in. For example...
The officer would see "Approved by Officer" status. The director would see "Approved by Director" status
I am trying to add these programatically to a dropdownlist which I have in the edit template of my gridview (approvalsGrid). Here is my code:
Protected Sub ApprovalsGrid_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles ApprovalsGrid.RowUpdating Dim ApprovalEditDD As DropDownList = CType(ApprovalsGrid.Rows(ApprovalsGrid.EditIndex).FindControl("ApprovalEdit"), DropDownList)
[code]....
I do not get any errors. But get an empty dropdown with no items. Am I using the correct event?
The user will click the book name in the combo box.
Note: The combo box is separate from datagridview . It is not part of datagridview columns.
Then the datagridview for Issuing books i.e. with the columns bid,bname,aname,data of issue,date of return should be displayed.
The row that will be displayed in datagridview is such that the bookname selected by user in the combo box should match with bname row .
On the same datagridview there will be button with name "Issue" so once it is clicked then this whole data of datagridview should get stored in the database table name "Issue" and get deleted from the databse table name "MBA"
I have an ASP.net web page with VB code behind linking to an MS SQL DB. On the web page I have 4 DropDownLists and 1 GridView. Each DDL is populated with a SELECT DISTINCT query on 4 corresponding columns from 1 table in the DB. What I would like to be able to do is: when any of the DDLs have their selected item changed the other DDLs are updated. Crude example:
I have the following problem: I select a customer from a dropdownlist and then the gridview should load all items of all orders of that customer. I have the following query:
Dim allorders = From ord In db.Orders
Where ord.CustomerID = Convert.ToInt32(CustomerDropDownList.SelectedValue)
[CODE]..............
I also tried to modify the query as follows:
Dim orderitems = From oi In db.OrderItems
Where oi.OrderNumber = (From From ord In db.Orders
[CODE]...........
But this does not work. I just started using LINQ.
In my application,i have a gridview in which columns are created at runtime.Actually these columns are created when i am entering data in a database table.[code]where Column1,Column2,column3 may vary during runtime.i need to enter values to these columns during runtime.But i cant bind these columns because these are created during runtime.The first column "Description" will not change.It will remain constant.For each description, there will be values for each column.At last these data will be saved to the database.How to add columns in the gridview during runtime?
I am able to export a gridview to excel, my problem is that I cannot figure out how to remove the formatting from coming over from the girdview. Here is the code I am using to export the gridview: Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?

I've been tinkering with Delegates, and now Multicast delegates. Every time I invoke two delegates It only displays one of the two delegates per invocation.
I put Label1.Text = Watch.Elapsed.Milliseconds And notice that it goes from 0 to 1000 milliseconds and then back to 0 starting over every time.Then I do some tests and put,[code]...
Whenever I press e, it logs the value in count and displays it.[code]....
This should end program once it hits 5 milliseconds.But the problem is it doesn't.On one of my test runs i notice it does end, but only after a little while. Does this mean VB has a hard time detecting the stopwatch or something?
I am running windows xp media player. Everthing works fine except my photos. They show in library normal but when I select them to play they look as if they have visualized bars. No actual image displays. How can I correct this?
