I have the following code to generate a table with the necessary textboxes. Now i need to populate those fields with the data from the table. If it makes it any easier, the individual textbox values are stored in a table with a reference to the main recordID
How can i populate the correct textbox with the appropriate column value?

I'm creating 14 textboxes for every day in a month and user can select the month so i have o create them dynamically. But i can't reach the values in the textboxes.
When i don't create them dynamically like
<asp:TextBox ID= "TextBox1" name="TextBox1"> </asp:TextBox>
I can get the value from the C# side by using the
((TextBox)Page.Form.FindControl("TextBox1")).Text
However this moethod doesn't work for the textboxes that i created dynamically. I'm creating them in a loop it's something like;

Then i add the text box to the necessary places at my table.However i can't reach the textboxes when i use the same method
((TextBox)Page.Form.FindControl("!A uniqe ID!"));
It gave a null value...
Scenario is: I have multiple positions and multiple employees.
Now in one of my forms I know how many positions are there and corresponding to each position i want to show Employee DropDownList(DDL) and Text Boxes (Start Time, EndTime) and some comments for each position. Employee DDL will be populated from DB and Position name will be displayed on labels and that too are getting form DB
say at one instance i have 5 positions and then i want DDL of EmployeeName for each position and similarly TextBoxes for each positions Where i can ask user to full the information for each Position and user can save the data.
And at another instance similar behaviour is required if Positions are 10 , 3 , 8.
I want to create a gridview with the first column being the Job Number and then a variable number of subsequent column which are fordates. This grid is a data entry for hours worked on a particular date for a particular job. I wrote the code to get the correct number of columns and column headers but I am having trouble getting textboxes into the grid cells.
public partial class _Default : System.Web.UI.Page

I'm creating textboxes in the Page_Load event and giving them values, however whenever I load the details I am getting the same output. I always seem to get the first output I got, even on subsequent searches.Here's what my code with the irrelevant information missing:

If DropDownList has two values (e.g. "Item 1" and "Item 2") and has autopostback enabled, first time it will generate and show "Item 1" in the textbox (the default value for the DropDownList), but if this is changed and the autopostback fires, the textbox does not change.I've tried getting around this by creating a new TextBox, overriding the "LoadPostData" function to prevent this from loading, which got around the issue there, but then I couldn't view the data afterwards.
Any idea how I could get around this? I may be approaching this in the wrong way.Edit: I've added another item to DropDownList that removes TextBox, so that it can be re-created again. It seems to show the correct data when it is re-created after being removed, but if I'm attempting to just edit it, this isn't updating correctly.Edit2: Here's the rest of the code for this page in case this helps at all. The objects which I'm having issues with are SBUName and SBUComments, which are both TextBoxes. The same issue is also happening for SBUClientDropdown but I believe the resolution will be similar:
DBHandler DBHandler = new DBHandler();
List<string> clients = new List<string>();
List<string> clientGroups = new List<string>();

My 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 Replieswhat I am currently doing is creating an aspx form dynamically and saving its data by using Server.Transfer("PrssPage.aspx").
On ProcessPage.aspx I am using the Previous Page property to save the data entered by the user using the dynamically created form.
Each Dynamic Form is provided an ID for example 123.aspx
Now what I want to achieve is to repopulate the dynamically created aspx page with the user input values from database, plz note here that I do not have an aspx.cs page getting dynamically generated. I am only generating aspx page.
I've done this using bound controls like Repeaters etc but now I need to display information about a single file for example. SO i will pass the fileid in the querystring, then I need to populate some textboxes, autocomplete textboxes etc. and then save changes. what's the most efficient way of doing this?

I have a page of several textboxes, which I would essentially like to populate from a single query. However, to begin with, I find myself unable to even populate one textbox from one query!
I have based the following on a query previously advised to me for use with drop-down lists (hence the use of DataTable). I have adapted this as follows:
AddData.aspx:
<asp:TextBox ID="tbNewDataNum" runat="server"></asp:TextBox>
AddData.aspx.vb:
Partial Public Class AddData
Inherits System.Web.UI.Page
Dim CommonFunctions As New CommonFunctions
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]....
I would like the Page_Load event to populate the textbox with this query, so that the value is present as soon as the page is presented. Also, how would you advise populating many different textboxes in one go, with one query? Is this possible too?
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
I have created some dynamic textboxes with standard content.Does anyone know how can I read the content of these textboxes (assuming that user modified the standard content) when I press one button?This is how I am creating the textboxes:
foreach (string name in listOfNames)
{
TextBox tb = new TextBox();
tb.Text = name;
tb.BorderStyle = BorderStyle.None;
tb.BorderWidth = 0;
tb.Font.Name = "Arial";
tb.Font.Size = 8;
}
I would like to add textboxes when a button is clicked. I created a Panel with ID Pnl_language and I use the following code:
When I click, all the Textboxes are created successfully for the first time. But when I click for second or third time etc, it doesn't add more textboxes, it replaces the current with the next number of session. What should I do so it always add 1 more when I click?
I'm using the calendar extendar to populate the "StartDay" textbox. However when i choose that "StartDay", i do not want that date to be valid when i choose another date to populate the "EndDay" textbox. Can it be done? i've tried any methods but it didn't seem to work.All i've manage to do was to check if the date was in the past.

I have developed the below web page which has an asp.net 3.5 listview control as it's frontend and an sql server db as it's backend.
[URL]
The first row on the web page is the inserting row. What I am hoping to achieve is that when the user enters their appropriate data they click the "Next" button to assign this dataset with it's own identity ID (customer_id) value within my database (this works perfectly), at the same time on the fly I want to use this customer_id as a query string variable to populate a child page (customerTrades.aspx) in order to pin further data to this identity. Currently I am attempting to use the below code within the iteminserted event of my listview control but I receive the error: "object reference not set to the instance of an object"??
protected void lvTrustAccounts_ItemInserted(object sender,
ListViewInsertedEventArgs e)
{
string customerID = e.Values["customer_id"].ToString();
Response.Redirect("http://www.tradeselector.co.uk/customerTrades.aspx?customer_id="
+ customerID + "");
}
Is this because the child page cannot find the customer_id variable being passed through the query string? Because it's not actually created yet? Am I using the wrong listview event? How can I achieve what I am looking for?
I must also mention that I'm using a linqdatasource to insert my data on runtime into my database. However, I am using the listview iteminserting event to insert my frontend dropdownlist selected values, code below:
protected void lvTrustAccounts_ItemInserting(object sender,
ListViewInsertEventArgs e)
{
e.Values["customer_created_date"]
= DateTime.Now;
e.Values["customer_update_date"]
= null;
DropDownList ddl_CountyInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountyInsertDDL");
DropDownList ddl_CityInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CityInsertDDL");
DropDownList ddl_CountryInsert =
(DropDownList)lvTrustAccounts.InsertItem.FindControl("CountryInsertDDL");
e.Values["customer_county_code"]
= ddl_CountyInsert.SelectedValue;
e.Values["customer_city_code"]
= ddl_CityInsert.SelectedValue;
e.Values["customer_country_code"]
= ddl_CountryInsert.SelectedValue;
}
