C# - Inserting New Row In Gridview Using An External Add Button And A List As Data Source
Sep 27, 2010
I have a grid with three columns, two of which contain drop-downs, all of them getting filled from a web service result set. Now I want to allow the functionality of adding a new record in the grid by clicking an Add button present outside the gridview.
Whenever the user clicks the Add button, a new record should be created in the grid with value list filled in the drop-downs with the available options.
What is the best possible way to achieve this considering extensibility in mind.
is it possible to have a button defined outside a grid view and give it a command name of "select" and somehow attach it to the gridview, so the grid recieves a select command when clicked without writing code?
void Session_Start(object sender, EventArgs e) { // Code that runs when a new session is started [code]...
basically am using them to store user id and status, so that pages can be validated, by there use.i can stop person from accessing home directly wihtout signing is and so on.can session variable be hacked as they are stored in an external data source and are available to the full website?
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I am developing one asp.net application and I have a requirement that I need to fetch html of page: [URL] I can easily do it with asp.net code using httpwebrequest but I have to do it from client side either using javascript or JQuery or any other thing. This is required becaues REQUEST TO GET PAGE [URL] MUST COME FROM CLIENT AND NOT FROM SERVER DUE TO IP ISSUE.
My problem is this "I have all the tools, VS 2005, 2008, 2010. I have every book, I have SQL server 2005 and 2008" I have all the tools, but I do not know what tool or technology to use when starting out learning all this. I juat do not know what book teaches what I need to do for something like below.
Here is my question:
I created an .ASPX webform that is to "Submit" to a SQL 2005 database. I gave this form to my DBA, and he has made up a Data Model. Now I have to figure out how to write the ASP.NET code so it will submit to the DB. My first issue is not knowing this:
1. "How do I loop through my CheckBox List", and then insert the values checked into a "Database Table" (Each Checkbox value MUST be a seperate row in the table, the DBA does not want a seperate column for each checkbox value)
2. The database is using stored procedures
3. My third issue is this: "I do not know "where" to put the "code". If you do resond to this,
Summary: I just need shown the code on how to "loop through" the CheckBox List on my form, and insert those values into a database table as seperate rows.
UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand
UpdatePanel2 has gridview2.
There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels
The behavior I would like is:
1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.
In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?
i wanted to retrieve things from the data base and perform mathmatical operations on it then post it to the user, so i was told to use the bullited list and bind it to the object dataSource
This should give me the friends of the user currently logged in in the Repeater, but gives me an exception on the runtime that an instance needs to be initialized, can you please suggest a solution...
Also, what should be the value of the NavigateUrl property of a Hyperlink in an ItemTemplate if the url is:
"http://domain.com/viewprofile.aspx?id=" + 'THE UserID property of the current element in the list'
I have a form where i want to view all columns from a table.I have a textbox and differeent radio button having values of each column.On click of button.I want to view all the columns as per selected row/rows from value given
I want to save data to a different table. My save is working fine but the challenge is that it saves empty cells as well.I will like to save only QTyDelivered cell with value. Any empty QTyDelivered cell should be ignored (which means the row of QTyDelivered cell that is empty will not be saved) .How can i achieve this?
Here is what I need to to. I have a gridview which I have a column that has a link to a pdf file on our file server. When I click the link I need to go into a database and update a column that they clicked the link then I need to open the file. by usinga HyperLinkField I am able to put in the link that I want to go to and when the page is running I can click on the link and it goes to the page and everything works fine except for being able to update the database part.
[Code]....
I tried using a ButtonField where in the code behind in the GridView1_RowCommand I pull out the file path and put it into a response write statement the problem I'm having with it is that when it opens the file it removes all the ""s so I get the error file cannot be found.
I am having a button inside a datagrid and in the button content i have placed a image.I tried to change the souce of the image from datagrid list but the image is not binding. I used MVVM Model .
I have radio button list in a gridview that needs to be bound to a column. If the value in a column is 0, the first radio button is selected, if 1, the other is selected.
This is the code, some of it is partially removed because it is not necessary
I have a gridview set up to bring in all of the items listed in the radiobuttonlist. When the page loads the first time it comes in as showing Over 250 only:
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound GridView1.Columns(2).Visible = False GridView1.Columns(3).Visible = False GridView1.Columns(4).Visible = False End Sub
This is the code behind:
Protected Sub PopulateGrid(ByVal sender As Object, ByVal e As EventArgs) 'Select Case Pending.SelectedItem.Value ' Case "300" Dim conn As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("PendingClaimsConnectionString").ConnectionString) Dim cmd As New Data.SqlClient.SqlCommand
[code]...
I'm getting an error under the If pending.selected value = "300" and .Parameters.AddWithValue etc...saying operator AND is not defined for types Boolean
Private Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound GridView1.Columns(2).Visible = False GridView1.Columns(3).Visible = False GridView1.Columns(4).Visible = False End Sub0
I am trying to insert a buttonfield at the end of the datagrid. I am using the following code. However, it is getting inserted at the beginning of the datagrid.
