Say for example, I have script like below whereby everything is same except the table name and each table name will append an incremental number, is it possible for me to have a for loop to dynamically add the incremental number?

A short background about this project: I'm creating an image gallery where images are uploaded and sorted into a category and then a subcategory, eg. "Vehicles" and "Cars". Every subcategory has a variety of tags to further categorize the picture, eg. color and make in the cars subcategory.
These tags (named "Criterias") are listed as DropDownLists through the following piece of code:

My problem now is that I can't figure out how to loop through them to find what criteria values to tag the image with.
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
im learning t-sql, infact i needed its while-loop to loop through records of a table, i found this code in some book:
[Code]....
i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?
if the underlined select statement returns one record everytime it is executed, isn't it supposed to return the same first record of the table everytime? is there a better way to loop through a table's records?

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 4 RepliesMy users have "demanded" to have an export function to their gridviews, and since they're running from usercontrols there's no way to modify the response stream. My workaround is to create an aspx to run in a hidden iframe. To do that, and to make it modular, I'm trying to dynamically create everything from the querystring. This *seems* to work just fine until I bind my sqldatasource to the dummy gridview. I then get "Procedure or function 'xxx' expects parameter '@NumberResults', which was not supplied."
View 1 RepliesI have an html table with rows and cells. And I have dynamically created a label and would like to assign the label to one of the cells of the table. What I am doing is I have a JavaScript which executes a code behind method and it would not accept an already created asp.net label. So I have created the asp.net label programmatically but cant assign it to the table to display the text value of the label. Below is the code:
[System.Web.Services.WebMethod] public static void EndCandiateTest(){
try { totalTestMarks = ts.RetrieveResults();
grade = tsp.RawScoreAndGrade(totalTestMarks);
remarks = tsp.ScoreInterpretation(totalTestMarks);
testResults = "Raw Score: " + totalTestMarks.ToString() + "
Grade: " + grade + " Remarks: " + remarks;
ts.ShowResults(testResults);
} catch (Exception e) {
} }
protected void ShowResults (string results). I want to display this label in an already existing html table.
messageLabel.Text = results;

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 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.
View 1 RepliesI 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) {

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.

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?

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.
