i have d design for dynamic textbox control ..but now i want to save the data values from the dynamic textbox...refer my following codings for design and based on that suggest me the codings for saving the data...
Default.aspx:
<form id="form1" runat="server" >
<asp:TextBox ID="TextBox1" runat="server" Height="65px" Width="600px"
style="margin-left:3px" ></asp:TextBox>
<div>

I have a self-made webuser control named UCLabeltextBox with 1 label and 1 textbox. When pressing the save button the page is refreshed and the value of the textbox is erased. Anyone a solution to this? Here's my code:
[Code]....
My Code to be fired During Button
protected void Button2_Click(object sender, EventArgs e) {
foreach (Control ctl in Dynamic.Controls) {
if (ctl is TextBox) {
TextBox tb = (TextBox)ctl;
using (SqlConnection con = new SqlConnection(_connStr)) {
[Code] .....
PlaceHolder
<asp:PlaceHolder ID="Dynamic" runat="server">
</asp:PlaceHolder>
I am not able to find the TextBox inside Placeholder. The Ids are also randomly Generated. I debugged it but the code comes out of foreach loop .
Here is my .aspx page
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> <tr bgcolor="maroon"> <th>
Subject Id </th> <th>
Subject Name </th> <th>
Obtained Marks </th> </tr>
</HeaderTemplate> <ItemTemplate>
[Code] .....
c# - code behind
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
this.PopulateRepeater();
} } private void PopulateRepeater() {
[Code] .....
Current repeater looks as...
Subject_Id Subject_Name Marks
s1(lable) subject1(lable) 56(textbox)
> Now, I want to make Updation with repeater (in same application).
I want to update Marks(into textboxes only, sub_id and name fatched from database dynamically) in each row of repeater.... how is it possible ??
What I want to happen is, I will populate or load the patient Name into TextBox. If the patient are 20, the page will dynamically create 20 textboxes to display the patient name..And when I click save, Changes will be save base on the input on textbox..
View 1 RepliesI have generated dynamic text boxes for each table row there are 6 text boxes
1. For the first two text boxes the values given by the user should be in valid range(this range comes from the database).User is allowed to enter the value within that specified values only. How to achieve this? I have taken drop down lists but if the values in drop down increases selecting required value is tedious to the user.. (if it is having 1000 values) and while I am retrieving the values I have written query such as Null values ignored. But I am getting NULL values in the dropdown here is the code what I have written,
(Database is Oracle)
If
Not (OledbCmd.Equals(String.Empty)
Or OledbCmd
Is
Nothing)
Then
OledbDA.SelectCommand = OledbCmd
OledbDA.Fill(ds, "textDB")
dt = ds.Tables("testDb") If
(dt.Rows.Count > 0) Then
ddlist.DataSource = dt If UCase(s) =
"NUMBER"
Then
ddlist.DataValueField = "num"
ElseIf UCase(s) =
"NAME"
Then
ddlist.DataValueField ="name"
End If
ddlist.DataBind()
ddlist.Items.Insert(0,
"Select")
ddlist.SelectedIndex = 0 Else
ddlist.Items.Insert(0,"Norecords")
End If
End

2. In the rows generated when user presses functional key F3 then the values of the above row(previous row) have to be copied in present row. similarly for F4 column copying. This I achieved through the Java script. But I have many forms requirement is same. where as text boxes id differ. how can I generalize the One function to work for all forms. I wrote as like this.
document.getElementById("No"+ cnt).value = document.getElementById("No" + (cnt-1)).value;
document.getElementById("Name"+cnt).value = document.getElementById("Name" + (cnt-1)).value;
For all the 6 text boxes.where as for column copying I wrote as
document.getElementById(id + cnt).value = document.getElementById(id + (cnt-1)).value;
here id is the text box id Which I am passing.
I am using this reference to make some application .. In this article we can only save with varchar data types
So how to use some other data types like datetime, money, int..or how to use parameters to convert data.

i have added one textbox as a template in my gridview.i want to get the values of textbox to a string when i enter values to the textbox.
View 1 RepliesIn my asp page when press a button, a gridview will be populated with data from db, but beside the columns from database i need a new dynamic column in gridview, to contain only dropdownlist with items number from 0-n.
This far i managed to do it, with some research on internet (i used an intemerdiet datatable to apply ItemTemplate from GridViewTemplate class, and than merged it to datatable containg the result from query, so the gridview's datasource si the merge of this 2 datatables).
The issue is that i don't now how can i access the values selected by user in the dinamically dropdownlists, 'cause i have to save them in DB.
Attach is my GridViewTemplate class code, and .cs and .aspx code.

3) and How do you compare the 2 dynamic fields? For eg: Im comparing the tbSch[i] to tbSch[i], so that the dates cannot be the same, am using a compare validator, but it throws me error that im comparing the same fields :) even though i change to ("tbSch" + i) for both, sorry Will provide my code snippet as follow :D tbNum is a textbox where user enter numbers and click generate
protected void btnGen_Click(object sender, EventArgs e)
{
for (int i = 0; i < Convert.ToInt32(tbNum.Text); i++)
{

cvSame.Type = ValidationDataType.Date;
cvSame.Display = ValidatorDisplay.Dynamic;
cvSame.EnableViewState = true;
cvSame.ControlToValidate = (tbSch.ID);<<<<< what should be the value in here?
cvSame.ControlToCompare = (tbSch.ID);<<<<<<<<<< and here?

I have a dynamic textbox appearing in a gridview on the row editing function. I have the following code to set the focus tot he textbox:
GridView1.EditIndex = e.NewEditIndex
BindData()
GridView1.Rows(e.NewEditIndex).FindControl("txtTargetAmount").Focus()
This works fine, but I would now also like to select the data in the textbox so the user does not have to select the text before typing, they can just type straight away. I have been trying to use:
txtTargetAmount1.SelectionStart = 0
txtTargetAmount1.SelectionLength = txtTargetAmount1.Text.Length
but this does not work.
I have a two buttons ( button1 and button2 ), a panel ( panel1 ), a label ( labe1 ) on my Web page ( coded with asp.net and c# ). I want to create 2 textboxs on my page when I click on button1 ( button1_click ).
After that, when I click button2 ( button2_click ), I want to get data of textbox (added on runtime) and write them on label1.
This application is part of my master application. This is very important for me...

View 6 RepliesI am Developing a database web applicationI am Creating web controls on page at runtime i.e in Page_Init event. No textbox are placed on .aspx page at design timeI have a datatable filled with a single record.now i want to bind a textbox (created at runtime) with a column of datatable so that when a page is loaded value in datatable's column is displayed in textbox.Other Important thing i want is when i make any changes in Textbox, It should be reflected automatically in a column to which textbox is binded. So while saving records i can save it directly from datatable. I dont want to write following tedious code before savinge.g.
DataRow mDr = Datatable.NewRow();
mDr["EmpId"] = TxtEmp.Text
mDr["EmpName"] = TxtEmpName.Text
Datatable.Rows.Add(mDr);

I'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).
The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...
I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.
I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId
I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:
