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.
View 1 RepliesI'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.
On runtime I am creating table structure using javascript and appending it to the div which is placed in an update panel. Problem here is, when I use asp.net button control, onClick of the button it posts the page to server and whatever javascript tables I have created it goes off. When I use html input button (input type="button") I don't face this problem and tables also stay there. But I have to use asp.net button to take necessary actions on the server side. Is there any way that I can restore the structure or use asp.net button control alongwith dynamic javascript.

I've created a bunch of asp:hiddenfields dynamically at runtime in an asp.net page.
My question is this:
How do I find those hidden fields?
I have an event attached to a control that fires a javascript function, and that's where I am attempting to use JQuery to find the hidden field associated with that control.

Im creating a table dynamically in my codebehind to display some statistics. The table is in a usercontrol. When the page first loads, its created and displayed correctly. If I do something that generates a postback, the table subsequently disappears, this is because its created inside a !IsPostback. How can i ensure that the table, once its been generated, stays visble on the page ? I dont want to generate it each time the page loads as it involves a lot of calculations on the database which will slow the pageload down.

View 1 Repliesi've dynamically created new rows on button click in gridview with 3 dropdownlist.for the first default row the selectindexchanged is firing and on pageload 1st ddl is loading with values and basing on selection the second ddl is showing values and third ddl is showing basing on second ddl. Now, when i click add new row, a new row is created with 3 ddl's ...1st one is showing properly but when i select from that ddl ,it should show data accordingly but its not showing particular data but showing all realted data from DB.same for 3rd ddl.
Also when new row is added and the first ddl is selected on postback the second ddl data is refreshing..
i wrote a function to create dynamic table in code behind on selectedindexchanged of checkbox,that is when user will check 2 checkboxex 2 tables will be generated with textboxes,Then on button click i want insert values of these textboxes in database,for that i want to find textbox using findcontrol,but i could not find it,
So i called same function of table creation on page load,but then it shows error that textbox is having duplicate id

View 2 RepliesIn my code I create a table dynamically and I try to restore the table after a postback. But although I recreate the table during the Page_Load event with the same id's before,the table doesn't appear with the same state and values as before.
I think it will be a typically beginner error, but I wasn't be able to locate the error whereas reading different posts and tutorials related to this topic.

I created a table dynamically with its row cell contain textbox. Now I need to show a hovermenuextender popup window on each rows textbox. I spend more time for this. But not getting till now.
This is my code for dynamically created table
private void GenerateTable(int colsCount, int rowsCount) {
string qry2 = "select lchannelname,ltransformdata from latestchannel where lenable=1";
DataTable dt = ob.getDetails(qry2);
dt.Columns.Add(new DataColumn("combined", System.Type.GetType("System.String"),
"lchannelname+ ' '+ltransformdata"));
//Create the Table and Add it to the Page
Table table = new Table(); table.ID = "Table1";
Page.Form.Controls.Add(table); int flag=0;
foreach (DataRow dr in dt.Rows) { TableRow row = new TableRow(); row.Width = 200;
TableCell cell = new TableCell(); TextBox tb = new TextBox();
tb.BorderColor = System.Drawing.Color.OliveDrab;
cell.BorderColor = System.Drawing.Color.OliveDrab;
cell.BorderWidth = 1; cell.Width = 200; tb.Width = 200;
// tb.ReadOnly = true; tb.Text = dr["combined"].ToString();
tb.ID =flag.ToString(); cell.Controls.Add(tb);
row.Cells.Add(cell); table.Rows.Add(row);
AjaxControlToolkit.HoverMenuExtender hrv = new AjaxControlToolkit.HoverMenuExtender(); hrv.TargetControlID = tb.ID;
Here I am confusing for which way is using for popup panel1
hrv.PopupControlID = Panel1.ID;
hrv.PopupPosition = AjaxControlToolkit.HoverMenuPopupPosition.Right;
Panel1.Controls.Add(hrv); flag++; } }
protected void Page_Load(object sender, EventArgs e) {
int numOfColumns = 1;
int numOfRows = ob.selectLatestEnableCount();
GenerateTable(numOfColumns, numOfRows); }
I want to popup this Panel1 on textbox through hovermenuextender

I am unable to reterive dynamically created table cells back color which has been changed by the click event of the cell.I am adding table cells dynamically on asp.net page and also setting cells back color. So when the page is loaded, table has number of cells with different colors.Table cells back color can be changed by clicking on it through java script. On page post back event, i am jutst getting those colors which were set before the click event.For example:When the page is loaded, cell1= red and cell2=red.If i click on cell2 then it will change to blue so now cell1= red and cell2 = bluebut on post back i am getting cell1= red and cell2 = red.Table is recreated on post back event.

Assume you have a page in ASP.NET where it makes sense to use JavaScript/jQuery to modify the DOM with values that will eventually be read by the server on submit. For example, you have a form that allows end users to add/remove objects (like dependents on a health insurance form or assets on a loan application). What are some ways to ensure that these items are detected and retrieved by the server once the information is submitted?
I've tried a few things that work, but none of them seem perfect so I wanted to see what the community had to offer. Also, I'm not looking for suggestions that avoid dynamic DOM elements (like use a Wizard, etc.). I'm specifically trying to improve my technique with dynamically created DOM elements.
in an aspx pege, on Page PostBack we generally get thsoe control that were created either in aspx or code behind (dynamic controls ). But in jQuery its common practice to craete new set of controls on the fly. Supose i have created 10 spans with some id and text . So, can we get these spans on server side on Page PostBack ?
View 5 RepliesSo 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
I have a table thats created dynamically, the table gets its contents from a custom class I've created that gets statistical data from a database. As the table is generated dynamically, I've put the contents class (the table data) into a session object and I populate the table initially inside a !IsPostback then on the page init I get the data from the session (its empty on the firts page load). I am now getting this error: Multiple controls with the same ID 'controlnamehere' were found. FindControl requires that controls have unique IDs. How can I avoid this?
View 4 RepliesMy problem is that I have an ASPX page which contains an ASP:Table. The rows for the table is added dynamically on Page_Load. One column in the table contains TextBoxes, BUT when I type something on a TextBox and cause a postback, I am unable to find the value just entered. And above that the table is not displayed after the postback.Can anyone help me please? I want to keep the table viewstate with the modified textbox values, so that when i post back to server, I can intercept these new values.
View 3 Repliesi am working on Accounting software.in this software i am to implement voucher entries form.In this form on page load a table (two rows and four columns) should be created after that one row should be appended to that table dynamically on button click event.
View 3 RepliesI've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.
function setDroppableTargets()
{
$(.cssDockZone).droppable();
}
But the elements with the class cssDockZone is created dynamically upon user interaction. So in the code behind i create the control first and finally at the end i register a scriptblock which calls setDroppableTargets().
//set droppable targets ClientScript.RegisterClientScriptBlock(this.GetType(), "setDroppableTargets", "setDroppableTargets()", true);
But the javascript function is invoked before the controls are created eventhough i register the script at the end (after creating the controls) and i cross checked it by getting the elements with class name '.cssDockZone' and i getting it as 0.
$(.cssDockZone).length
I am dynamically creating controls from javascript. Now i want to access this is server side.
I assigned all the control values from dynamically created controls to hidden field and accessed that in server side. For this i need to create many hidden fields as much as dynamically added controls.
Does anyone know how to dynamically add and remove rows in a table triggered by a button click from the backend (in c#) using asp.net?
Here's how it might be done in javascript, is there any way to do this in the asp.net framework?
