GridView Adding Additional Rows In Row Data Bound Event
Nov 1, 2012
I have a gridview that I bind on Page Load event.In the rowdatabound event I want to add a row to the gridview and bind it based on the value of the current record.The row is not being added. Is there a way to bind the extra row in the rowdatabound event?
Private Sub grdDocuments_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdDocuments.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim dt As DataTable
Dim dv As DataView = grdDocuments.DataSource
I've got a grid view on my form that is bound to a data table at run tim. The data table is returned by a function rather than direct from the DB so I can't set the datasource at runtime.
I bind the grid in the page_load event like this:-
Code: Dim _dt As System.Data.DataTable _dt = _srvc.GetVinylShutters(0) _dt.Rows.Add(_dt.NewRow) grdShutters.DataSource = _dt grdShutters.DataBind() (_dt.Rows.Add(_dt.NewRow) is just there to add a blank row in, otherwise I wasn't seeing any columns at all)
I've then got the following snippet which I want to use to hide some underlying columns:-
Code: For Each col As DataControlField In grdShutters.Columns Select Case col.HeaderText Case "OrderID", _ "ShutterID", _ "ModelID", _
[Code] ...
The thing is, wherever I put this it doesn't seem to hide the columns. If I break into the code I can see that grdShutters.Columns.Count equals zero althought I can see that the bound datatable has 38 columns.
I've tried the Page's Load, LoadComplete and PreRenderComplete events as well as the gridview's DataBound, RowDataBound and RowCreated events. I get teh same result in all of them. The grid doesn't actually have any columns until it appears on the screen.
I am using grid view with row "data bound event" at row row data bound i am using some function with loops to fill drop down of grid view in template columns. grid view gets populated with selected index change event of drop down. my problem is the asp.net page is getting slower i mean when grid populates its taking some time and some time page get hanged what to do to get rid of it?
I have been tinkering with a adding row to gridview code from [URL] I have been able to adapt it to my needs but I would like to have the user edit the select statement that shows the initial gridview form.
I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I follow this code [URL] it works. But the example is show only for 1 row.. come to my case when user want 12 rows for the first time gridview row load. I manage to add it by using for loop. but i stuck at the how to set previous data when user add new row to 13th row. The gridview seems like refresh and the entered data is gone!
I'm having difficulty adding a repeating header row, every x rows, to a gridview. I'm able to add the header only once with the below code. For some reason it will only add it during the last iteration through the for/next statement. I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement. I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.
Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number): Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound Dim grid As GridView = TryCast(sender, GridView) If grid IsNot Nothing Then Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal) Dim header As GridViewRow = POSTURE_RESULT.HeaderRow For i As Integer = 0 To POSTURE_RESULT.Columns.Count - 1 Dim TableCell As New TableHeaderCell() TableCell.Text = header.Cells(i).Text row.Cells.Add(TableCell) Next Dim t As Table = TryCast(grid.Controls(0), Table) If t IsNot Nothing Then For i As Integer = 0 To Gridview1.Rows.Count - 1 If IsWhole(i / 5) Then t.Rows.AddAt(i, row) End If Next End If End If End Sub
i have read and used this script.Adding Dynamic Rows in ASP.Net GridView Control with TextBoxes..it is very usful to me but i want to fetch data from sqll database and fill the newest row with it. the past row data hav to be remain same. becoz of the same name of textbox it happens. whenever i try to fetch data from database and fill textbox all rows get updated with the same data.
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 <<

protected void gvHotels_RowDataBound(object sender, GridViewRowEventArgs e) { DataTable dt = new DataTable(); if (e.Row.RowType == DataControlRowType.DataRow)
How can i stop of adding blank emply rows on my table, every time i click on the button to add row on one table of sqlserver?
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Using connection As New SqlConnection("Data Source=.SQLEXPRESS;Initial Catalog=teste1;Integrated Security=SSPI;") Using command As New SqlCommand("INSERT INTO TABELA1 (UM,DOIS,IMAGE)Values(@UM,@DOIS,@IMAGE)", connection) 'Configura os parâmetros. command.Parameters.Add("@UM", SqlDbType.NVarChar, 20).Value = Me.TextBox2.Text command.Parameters.Add("@DOIS", SqlDbType.NText, 50).Value = Me.TextBox3.Text command.Parameters.Add("@IMAGE", SqlDbType.VarBinary).Value = ConvertImageToByteArray(PictureBox1.Image) TABELA1BindingSource3.ResumeBinding() connection.Open() command.ExecuteNonQuery() End Using End Using Paulo
I am working with Gridview control and I am also adding radio button to each row in ASP .NET. Here is something that I would like to accomplish but I am not sure how this should done. The problem is that I have add a muliple datarow insie of the each gridview. Something like below.
So, some cases I have add a row with two rows like the example. And, the ID eventurally will be radio button where user can click.
while a new row is adding in gridview, the data is binding only new rows. the old rows are not coming.Data is coming from the profile properties.Add new row command event is listed below
bool isUserAccountCreated = false; UserProfile profilenew = new UserProfile();
I have a situation where I currently have a HyperLinkColumn control that I would like to modify to have a Label or simple text appear in the same column as the hyperlink. I tried setting this in the ItemCreated event but encountered the following error message
I'm new in ASP.net, i download your code from the below link.URL...I was searching from net to add a new row in client side i go thru this it was OSOME. I have another dought if you add a one link delete option to delete the row in client side.Another thing if we add a template field such as textbox and dropdown list then there no datafield then how we fill the grid from database.
I have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable
I have a application that i am creating in ASP.net i need to be able to update a new column in the table users which is set up automatic with a asp.net project. I am trying to add a address line to the code
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event. The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
I have checked this article link here and its good.. What i want is how can i avoid the button.. mean add the row dynamically without using the button click event.. Instead use text changed event..
I would like to know simple thing, If i'm adding additional information to UserProfile such as: Country, PhoneNumber etc'.. So, I added a Table In my DB (which also Got all Membership Provider tables...)
UserProfile, and added Stored Procedures for it for Insert / Update... I would like to know, If I need to create in Business Object a Class for Profile Only? (Cause the User is managed Already by the Membership Provider) And Create for it Also in Business Logic -> ProfileManager with Methods that will use the Stored Procedures to Update and Insert Details? Do I need to do it like this? Or there is another way? What's the right way doing it?
