AJAX :: Dynamically Add Table Rows Within Update Panel?
Sep 18, 2010
In my webform, i have 3-4 textbox, on there textchange event i have to fetch data from database and put it on the form. I have taken another html table (with runat="server") below textbox and and in textchange event created a new <tr>, <td> and simply added contents in <td>, then finally added <tr> in the table. This is done in UpdatePanel.
When i enter something in textbox1 data is added in that table,that's fine. But when i enter something in 2nd textbox the previous data is overridden. My requirement is that if 2nd textbox's text changes than another row with appropiate data should be added, i.e., now two rows. Silimarly if 3rd ,4th textbox data changes then subsequently 3 or 4 rows should be displayed.
I am trying to delete or add rows in a table but since the table is in an update panel,upon deletion the row goes away and then comes back.I have tried using return false but it does not seem to work in IE or FF.
i have an update panel, which contains a repeater inside. The repeater's data source will change on postback. The repeater will generate a div for each item.
I need to set the height of the div that is generated by the update panel to the actual total height of the div inside the repeater.
I am hoping someone can help me out. I have a web application that contains a usercontrol think "employment details" a user can enter a previous employment detail.
I have created a page that contains an update panel a placeholder and a button. The button I want to use to load a new copy of the same usercontrol. Can anyone point me in the right redirect?
I have a pretty simple C # page that when the page first loads, a bio is diplayed in that center section based upon sql executed from my code behind. I have 4 link buttons on the page that when clicked, fill that center section with other content based upon which link button they clicked (News, Publications, Contact Info, and Presentations). I was all done, then I thought about using an UpdatePanel to get rid of the annoying "flicker" when the page posts back on the click of the link button.
I have a grid view in Ajax UpdatePanel. In a column of a grid view I have a button call btnAddNewRecord. I need to fire btnAddNewRecord.Click event once I click on that.
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
I have table a and would like update table a whose values from table b, but not update all rows at table a. Only update record ID in table a match record ID in tableC.
Here is my query
update a set a.Desc = b.Desc, a.Value = b.Value from TableA a, TableB b where a.name = b.name and a.ID = b.ID and a.ID in ( select ID from TableC)
I only have 12 a.ID match TableC, but above query update whole TableA.
How to only update 12 record at TableA from TableB?
I have one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
So today I started learning ASP.NET. Unfortunately I haven't found any good tutorials online, and I can't afford to buy books at the moment, so I've had to create a ASP.NET web application in Visual Studio 2010 and just play around with the default project setup. So far here's what I have in my Default.aspx:
I created a simple table with the header row already in there. Through a C# script, I want to be able to dynamically add rows to this HTML table. Is this the right way of thinking in ASP.NET? If so, how can I do this? I'm sure I'll need an "Add" button, which adds a new row to the table, with editable fields, and a "submit" button which adds some stuff to a database. Basically just a rundown of how this is done would be ever so helpful. Also if anyone knows any good tutorials or websites
Protected Sub btnAddRow7_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddRow7.Click Dim tableRow As New System.Web.UI.WebControls.TableRow Dim tableCell As New System.Web.UI.WebControls.TableCell Dim textBox As New System.Web.UI.WebControls.TextBox tableCell.Controls.Add(textBox) tableRow.Cells.Add(tableCell) tbl7.Rows.Add(tableRow) End Sub
but it only adds one row dynamically. After the first addition, more clicks to the button will not add more rows.
my table has already 5 rows...after pressing addow, rows are added dynamically to another table... i need to save the data of all the rows(5+newly added) in the database...
i have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.
I have a panel bar..each time I press panel bar item I display ascx control with in update panel..but it lakes update panel loading time lot..how I can decrease that loading time?
I have an AJAX Modal Popup panel that contains a RadioButtonList, 2 labels and 2 DropDowns. I want to update the Labels and DropDowns when a radio button is selected. My attempt at this posts back which causes the ajax popup to disappear.
aspx called on image click: <asp:Panel ID="pnlModalContainer" runat="server"> <asp:RadioButtonList ID="rblTest" runat="server" RepeatDirection="Horizontal" OnSelectedIndexChanged="rblTest_SelectedIndexChanged"> [code]...
I created dynamically a table with 3 rows not by using table tag. I need to find these rows in scripting, in button click, if any of these rows is empty then need to generate an alert message like enter current row.
I'm maintaining a dynamically generated table in ASP.NET, which allows users to move items up and down in the table. What this essentially does behind the scenes is just swaps around the 'sortorder' which the table is sorted by. I have checks to see if a row is the first/last column, and if so only display up/down (whatever's relevant). An issue has crept up now and I have no idea why. For some reason, most of the time (not all of the time strangely) the up and down buttons don't work. Using 'Up' as an example, the current record does get set to the 'above' rows sortorder, but the 'above' row doesn't take the below rows sort order. Now I've set my breakpoints throughout my code, and strangely everything gets set fine. It's just when I call SubmitChanges() to the LINQ data context, that it seems to put the wrong value into the database. Also what's strange is that I think that if you click it again, it actually works. But it doesn't work properly as the number is still out by a bit.
Here's my code: if (Request.QueryString["dir"] != null) { if (Request.QueryString["dir"] == "up") { var currentrecordup = (from s in dc.InvoiceItems where Request.QueryString["val"] == s.id.ToString() select s).Single(); int valsortidup = (int)currentrecordup.sortorder; var prevrecordup = (from s in dc.InvoiceItems where s.sortorder < valsortidup orderby s.sortorder descending select s).First(); int prevsortidup = (int)prevrecordup.sortorder; int tempval = valsortidup; currentrecordup.sortorder = prevsortidup; prevrecordup.sortorder = tempval; } else if (Request.QueryString["dir"] == "down") { var currentrecorddown = (from s in dc.InvoiceItems where Request.QueryString["val"] == s.id.ToString() select s).Single(); int valsortiddown = (int)currentrecorddown.sortorder; var nextrecorddown = (from s in dc.InvoiceItems where s.sortorder > valsortiddown orderby s.sortorder ascending select s).First(); int nextsortiddown = (int)nextrecorddown.sortorder; int tempvaldown = valsortiddown; currentrecorddown.sortorder = nextsortiddown; nextrecorddown.sortorder = tempvaldown;} dc.SubmitChanges(); Response.Redirect("EditInvoice.aspx?id=" + Request.QueryString["id"]); } The sortorder column in my table is an int field that allows nulls.
I am using ASP.NET3.5, I want to Add rows dynamically to a table.I have written this code.This code is working fine if the Page is not having masterPage file. If I use masterpagefile in my ASPX age,controls(textboxes) are displaying at bottom of the page,and the data in textboxes is not retaining after click on Add button.Disaapering the text box values. My .Aspx:
Basically I have a usercontrol that is setup to capture a persons education details. I want to have a button inside the update that when the user clicks loads the usercontrol below the previous usercontrol.
I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
I've been searching for hours trying to figure this out. I understand that somehow I need to recreate the control in page_load. I think seeing the code will let us better understand what I'm trying to do.
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
