View 8 RepliesI have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx

Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

Now when I click on newButton, it does not validated dynamically generated textboxes, it does postback and every dynamic object disappear. The sample code is provided below.

how to populate textboxes during runtime in c#.net..
View 3 RepliesI have code that another member assisted with and is working great. Now that the page is working more and more like it should with the remaining requirments. I have something else i would like to implement.
Since the code i have automatically creates / generates a table with textboxes and labels based on a drop down selection. I would like to know how to clear the textboxes if they chose 0 from the dropdown. Or if they select "No" on the radiobutton, then that means they have nothing to provide, so i dont want to capture something that they may have entered before changing their mind.
Here is the code the generates the tables and textboxes, i just need to setup, so that if they select "NO" from the radiobutton or if they select "0" from the dropdown that the textbox values, if any, are cleared so that we dont get inconsistant data captured.

I am generating dynamic textboxes with the ids as follows table row 1:
no1,name1,addressline11,addressline21,city,pin,communicationAddress1(here the row count I am appending at last to the control id's)table row 2: no2,name2,addressline12,addressline22,city,pin,communicationaddress2
table row 3: no3,name3,addressline13,addressline23,city,pin,communicationaddress3 and so on....
A new will be created when user hits enter key in the last textbox i.e., communicationaddress.For validations I have used java script. Now my requirement is when user types the address line the content of the textbox should be copied to communication address.
communication address = addressline1+addressline2+city+pin
so in theabove four textboxes when the user hits the keys the matter appending to the communication address with ',' seperated. I acheived this through key press event in java script..................
I'm trying to make a form that could have one or multiple textboxes. I have a textbox and a button to add additional textboxes.
I have no problem adding a second textbox inside a panel but I want to be able to keep adding more textboxes every time the link button is clicked and later reference those boxes to be saved. I would also like to maintain the value of the textboxes there. They are not saved to the database until all the necesary texboxes have been added.
I added the textbox using:
private void button1_Click(Object sender, System.EventArgs e)
{
TextBox textbox1 = new TextBox();
panel.controls.add(textbox1);
}
that works fine, but when i click the button again it doesn't add an additional textbox which is what i need.
i have a textbox (txt_inputchild) for entering no of children name.
and a Add button (btn_add) for increasing the no of children one by one.
how to write code in c# and how can i identify my dynamic textboxes id's to send data to database.

I have a DataTable where the columns are generated programmatically at runtime. I then bind this DataTable to a GridView. What I'm wondering is how I can create the GridView to accommodate this, and if it's not possible, how I can output the DataTable into nicely formatted HTML.
View 3 RepliesI have a Winforms app which provides the ability for users to create their own reports. At its simplest they design the query which gets encrypted and saved into a database.
The ability to view these reports via the web as now come upon us.
What is the best way to handle this? Ideally I want to use MVC but there will be no model or viewmodel because these queries can return data for any table across the application and so I cannot have hardcoded propeties etc. Obviously I have access to the SQL to execute it.
I wonder if tradtional ASP.Net may perform better in this scenario ie/execute the SQL and put it in a DataTable but was hoping to get some thoughts from the community.
Problem for me is that a tag is being generated that apparently just moves the treview a little bit. So I am thinking I should delete it at runtime. How do I do that?

I have implemented a user control with dropdown lists and textboxes where user may choose to add more of the same user control dynamically then submit the values within all usercontrols at the same time. They way I added usercontrols dynamically is whenever user clicks "add more" button, it increases the value of "userControlAmount" in session by 1, reloads the page and during next page_load event, within an updatepanel it creates usercontrols on the fly.
However whenever more is added since all usercontrols are generated again according to the latest user control counter, the values within the dropdownlists and textboxes are getting reseted.
I can hold all values in a viewstate/session however beyond the time/effort it will take, it doesn't sounds very "professional" to me. I was wondering if there is a more efficient way of doing this.
Is it possible to add values in textboxes as well as subtract values? Scenario:
txtbox1 value = 3
txtbox2 value = 2
txtbox3 value = txtbox - txtbox2
I am using this code which works perfect when I type username and the studentid in my textboxes in the first page.Now after pressing the button to go to the second page , the two labels display the values of the textboxes in the first page BUT when I am pressing a button in my second page I get this error :
Object reference not set to an instance of an object.
My code which is in the second page load event is :
Label1.Text = "Name:" + CType(PreviousPage.FindControl("txtusername"), TextBox).Text
Label2.Text = "Student ID:" + CType(PreviousPage.FindControl("txtstudentid"), TextBox).Text
Is there any option to make this labels keep their values ??
I have some textboxes and radio buttons in my form, and when the user clicks the "Search" button, an SQL select query is run from an SQLDataSource and that query populates a gridview. I want some of the values in these textboxes/radiobuttons to act as search criteria and I'll form a WHERE clause based on what the user typed into them. How do I do this?

I have a textbox and the date needs to be in between two dates. I want a popup message to display when they are out of those parameters. I don't want to use the Validator's because they make you put in a date to move forward.
One option is if I do use them is it anyway to add "out of date parameters" when they don't meet those dates then move to the next question?
Another option would be to just check the date, give an error message and move to the next question. Is it possible to do either one of these?
I create textboxes in codebehind based on user choice from a dropdown. The user then fills in thevalues of those textboxes and clicks a linkbutton to save the values. When I try to access those textbox values, they are null.
aspx code: <asp:PlaceHolder runat="server" id="TextBoxesHere" />
VB Code:
Private Sub CreateTextBoxes()
Dim ct As Integer = ddlAYIntervals.SelectedValue
TextBoxesHere.Controls.Add(New LiteralControl("<br><table id=""NewIntervals""><tr><th>Interval Name</th><th>Start Date</th><th>End Date</th></tr>"))
' now, create n TextBoxes, adding them to the PlaceHolder TextBoxesHere.........

how to add gridiview footer row textbox values to a database....
I have Grid view control in the page. Enable paging option is true.
Columns in the Grid view are ID, Name, Checked and Email
Whenever user selects the check box then I am showing txtEmail in the Email columns so that I can enter email id in the textbox.
Like this I am selecting checkboxes and entering values in the txtEmail when I go to next page and comes back. Then these entered values are cleared.
