Data Controls :: Populate GridView Using ArrayList
Aug 19, 2013
I'm new to asp.net and I'm trying to implement a shopping cart.With the following code (. Vb):
PartialClass a Inherits System.Web.UI.Page Protected Sub Page_Load(sender As Object, eAs System.EventArgs) Handles Me.Load Dim FileNames As ArrayList =Session("SessionCarrito") If FileNames IsNot Nothing Then For Each Fname As String InFileNames ListBox1.Items.Add(Fname) Next End If End Sub End Class
That code shows a ListBox with the file names that are stored in a session variable. Works fine but I need to show those filenames in a gridview which also display a ID for each item and a button that will eliminate these items. How I can change my code to work with a gridview?
I have a GridView control of 5 columns out of which 2 are actually computed (there cell values comes from column 1, 2 and 3) columns. I want to save all the values of my gridview columns in a 5 dimension ArrayList and then lateron bind that ArrayList with a repeator control.
I've been trying to bound an arraylist to a grdview for display and managed to work out the following:
[Code]....
At the point where rows are added to dt, i'm trying to get arraylist (Tweet) to be read row by row to insert each of it's fields into dt. There is no error but when run in browser, each cell of the gridview shows 'DataExtraction.Tweet'.I'm not sure where to go from here.
I want bind GridView from database using ArrayList. But my code not worked.I shared code below:
public System.Collections.ArrayList GetTime(int user, int kod) { SqlConnection con = new SqlConnection(UserData); SqlCommand cmd = con.CreateCommand(); System.Collections.ArrayList result = new System.Collections.ArrayList(); string sql = "select kod,dshbe,sshbe,chshbe,pshbe,jma,shbe,koduser where koduser ="+user+"and kod =" + vr;
I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.
Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.
>>
Private Sub LoadDataGrid(ByVal numberOfRows As Integer) Dim Counter As Integer Dim GridList As New ArrayList For Counter = 0 To numberOfRows GridList.Add(New LibVB.Form2VB(Counter)) Next gvEnterParts.DataSource = GridList gvEnterParts.DataBind() End Sub <<
I'm lost, kind of a newbie to .net, have been working on this for 2 days! d.
I am working in asp.net 3.5 with c# and sqlserver 2005 as database. I my project i have to select some of the checkbox of a gridview and update the database according to that. I want to store all the selected box in a arraylist and update the database according to the selected list . But i am not getting how to proceed.
I currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn 1 1111 2222 3333 Yes / No (selected Yes) 2 2222 3333 4444 Yes / No
I have two gridviews on a form. When the user selects a row from the first gridview the second gridview should populate based on the selected row. The second gridview is not generating as expected. If I remove the "@vendor_id_fk" from the WHERE clause of the query and replace it with a value, the second gridview generates when a row is selected in the first gridview. So I know that's where the issue lies, but I am having some difficulty solving the problem.
I am quite a new to the ASP.NET field and trying to populate a gridview with data from xml file. I have already done this using code bihind(C#) when the xml file is simple, like below: Dennys 730 W. Carson St. Torrance CA 90502 5625555555 4 The best burger joint in California! And code bihind: protected void GridView1_PreRender(object sender, EventArgs e) { DataSet ds = new DataSet(); ds.ReadXml(Server.MapPath("RestaurantData.xml")); GridView1.DataSource = ds; GridView1.DataBind(); } But say if I have multiple child of a node in the XML file, say, Dennys 730 W. Carson St.Torrance CA 5625555555 [URL] Then how to load this data(phone & website) in a gridview column using code behind(C#)? And what else I have to do with my aspx page also?
I am trying to fill a gridview inside a repeater and I am getting an error. Firstly, here is my code for the page...
[Code]....
And next is my code....
[Code]....
So basically what happens is, the accordion is populated by a dataset and in turn the gridview is then supposed to populate with data depending on the hidCusType from the parent pane of the accordion.
But I get the following error...
The name 'AccordionItemType' does not exist in the current context on this line...
How do I populate a gridview calling an XML WebService?
protected void Page_Load(object sender, EventArgs e) { var proxy = new myWebService.integration_io(); var xmlResponse = proxy.ProcessClientAction(xmlRequest); var parsedXmlResponse = XElement.Parse(xmlResponse);
now, when the user clicks on the button in the header, I would the gridview to contain an extrarow with blank textboxs which the user can type information in and save that information. So that when the gridview gets shows again, it contains the new information.
Lets say I have ListBox1 (1,2,3,4,5,6) and a ListBox2 (A,B,C,D,E,F)..
and a Button and a GridView. Now when I click the Button. I want a GridView Column 0 to be populated by ListBox1 and Column 1 to be populated by ListBox2. . C# / Asp.net.
I have a gridview populated by a SQLDataSource that is fairly complicated on a dataset changing constantly. It takes a second or so to fetch the data.
I want to have external dropdownlists for filtering the data that appears in the gridview, either with a FilterExpression or with parameters.
The problem is that querying the database to populate the dropdownlists takes a long time, because of the complexity of the query. The values in the dropdowns can vary based on other filters.
Is there some simple way of querying the database only once, for the main gridview, and then somehow querying the local (to ASP.NET) copy of the data to extract distinct values for populating the filtering dropdowns? I am thinking this might speed things up a bit.
i want to create a arraylist which will able to store user info like (username,machineIP,port ) for each user in the list & retrive this data when needed . any one tell me how i can do it or any alternative way without database or xml file.
i have a dropdownbox and a gridview what I want is to have a list item which populates all data in a gridview. I have tried using list item selected value=0 but to no avail. what is the easiest way to achieve this?
I need to create a gridview to show in each row, some columns from the SQL Database, and in other columns I want to have text fields, buttons and DropDownLists!
This GridView is to display the users of the web application.
First columns are name, email, and other stuff that can be easly queried to the SQL database.
Then, I need to have a column with one text field, and some buttons, in the text field the AdminUser should be able to insert some text and then click in a button to change the email/pass from the user represented in that line.
The other field I need, is a DropDownList that shows by default the Role of the user of the row, but we can choose another role and apply it, with a button in the same cell!
If I create a code-Behind query and populate the GridView, I don't know how to insert textbox's, button's, DropDownList's
If I create the GridView with the wizard, I can had TemplateFields, but I don't know how to associate the query with the BoundFiels where should be the name/email of the users.
Other problem, is that, even If I get to construct my GridView with sucess, How can I reference the row? So I can apply the changes?
I am trying to populate a gridview when you select the dropdownlist.selected value. I don't want to use the sqldatasource or any other datasource. I am trying my best to achieve this, but didn't succeed till now. One of my friend said that i need to get the selected value from dropdownlist and search for the data in the database using the selectedvalue and populate the dataset and bind to the gridview.
I have 2 drop downlists 1 gets the User hits my sql database and pulls back all my users in the database. I have post back on. The second drop down brings back all the account numbers for the user that is selected in the first drop downlist I have that post back on also.
My gridview then uses those 2 dropdownlists to populate for that user and that account number selected.
Now for the problem.
User Albert is in the drop down when page is loaded because its sorts by name the first account number for albert is in the 2nd drop down and the gridview works on page load for albert and account number 1 i can select account number 2 and the gridview changes.
I then switch user to Bill and it populates the 2nd drop down with Bill's account numbers however my gridview at this point is still showing alberts account information. I have to take drop down 2 and select another account say account 2 then my gridview displays bill's account 2 information i can then switch back to account 1 for bill and see that account information.
What do I need to do so that my gridview will populate when the first dropdown is changed to match the 2 new values?
