Web Forms :: Getting IDs Of Dynamically Rendered Text Boxes
Feb 20, 2010
I have a page that allows users to upload photos and when they click the upload button it renders a few textboxes used to change the photo's information and also the displays the photo. After they are done upload photos, they can then insert all the information in each of the textboxes. Then users click the Upload button and it takes all the information and places it in the database. The problem is that when I say "get the text from these textboxes" using the textbox IDs, it tells me that those textbox IDs are not in the current context.
Here is my code...

I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.

Using C# and SQL as the database.I have a page with a gridview and some text boxes and drop down list boxes. A user selects a record from the grid view I query the database and fill the text boxes and drop down list boxes.
Some fields get updated periodincally thus there is no data in those fields in the database until some time.
A strange thing happens.When filling data some text boxes gets a one tab spacing .

I hope this is in the right sections....if not please feel free to move it. Does anyone here have examples of how to create multiple text boxes dynamically based on a search result? For example A table has 5 rows. how do I output to the screen 5 text boxes? and then get their details later? (so in a week if there are 15 rows in the table , then 15 text boxes are output) also what would be a good search term on Google for this so I can try and find other examples as the search terms i was using returned zip

I have written the following ocde to save the data in to textfile.
using(TextWriter tw=new StreamWriter(file))
{
string refcode = txtReftypecode.Text;
tw.Write(refcode.PadLeft(1,'0'));
string priorcode = txtPrioritycode.Text;
tw.Write(priorcode.PadLeft(2, '0'));
tw.Write(txtImmediateddest.Text.PadLeft(2,'0'));
tw.Write(txtImmediateorg.Text.PadLeft(10,'0'));
string date=txtFilecreatdate.Text.Replace("/","");
tw.Write(date.PadLeft(6,'0'));
string time1=txtFilecreattime.Text.Replace(":","");
tw.Write(time1.PadLeft(4,'0'));
tw.Write(txtFileIDmodifier.Text);
tw.Write(txtRecsize.Text.PadLeft(3,'0'));
tw.Write(txtBlockingfac.Text.PadLeft(2,'0'));
tw.Write(txtFormatcode.Text.PadLeft(1,'0'));
tw.Write(txtImmeddestname.Text.PadRight(23,' '));
tw.Write(txtImmedorgname.Text.PadRight(23,' '));
tw.Write(txtRefcode.Text.PadRight(8,' '));

I have placed the code below on a page. The strange thing is that the "SOME TEXT" string doesnt show up in the page! I do see "upanel" and "pnl":
upanel
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
pnl
<cc1:TabContainer OnActiveTabChanged="TabChanged" ID="tabContainer" runat="server"
ActiveTabIndex="0" OnClientActiveTabChanged="ActiveTabChanged" Width="100%">
<cc1:TabPanel ID="tp1" runat="server" HeaderText="A tab">
<ContentTemplate>
<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode="Always">
<ContentTemplate>
SOME TEXT
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</cc1:TabPanel>
</cc1:TabContainer>
</ContentTemplate>
</asp:UpdatePanel>
HOWEVER, when I view the pagesource, I see this, so the text IS rendered to the browser! What can be happening here?
upanel
<div id="ctl00_CPHCenter_UpdatePanel2">
pnl
<div id="ctl00_CPHCenter_tabContainer" style="width:100%;visibility:hidden;">
<div id="ctl00_CPHCenter_tabContainer_header">
<span id="ctl00_CPHCenter_tabContainer_tp1_tab"><span><span><span id="__tab_ctl00_CPHCenter_tabContainer_tp1">A tab</span></span></span></span>
</div><div id="ctl00_CPHCenter_tabContainer_body">
<div id="ctl00_CPHCenter_tabContainer_tp1">
<div id="ctl00_CPHCenter_tabContainer_tp1_UpdatePanel3">
SOME TEXT
<div>

I am creating n number of Combo boxes dynamically at run time and adding a Handler of Combo1_SelectedIndexChanged() to the combo boxes.
At run time, When I select an item from one of the Combo boxes, the event fires n times rather than 1.
So for example : If there are 5 combos created, and I select an item from my first combo, the event Combo1_SelectedIndexChanged() , fires 5 times and that is an issue for me. How can I restrict this to run only for the combo that I selected.

We are rendering usercontrols dynamically like this:
[Code]....
This lets us the same user controls when rendering pages normally as we do when rendering responses to ajax calls. However, when adding controls which themselves contain a scriptmanagerProxy we run into the problem that the newed up Page object doesn't contain either a ScriptManager or the HtmlForm in which the ScriptManager needs to run.

I have two text boxes called starttime and endtime which are datetime sqldbtypes that I want to subtract the value to show in a duration label. I know that you can do a subtraction with datediff in t-sql to find the time difference, and I'm wondering if that's the best way to approach this. Here is the code from my default.aspx.vb page:

I'm very new to ASP.NET, how would it be possible to have a complete form with, let's say, 10 text boxes. Once the page is displayed, the user would only see the first textbox. After the user has input data into that box, the second textbox would appear. After data is input into the second textbox, the third textbox would appear and so on. I know it probably has something to do with Postback but I cannot find anything on this scenario.

Response.Write("page loaded");
}
protected void Page_Init()

I'm developing a web form. I use the style sheet for the page and make the font size x-small.
But I noticed all the text boxes in the page looks a little higher than expected comparing with the font of the other text in the page.
Is there an easy way to change all the height of the textboxes on the page? and make new creation of text boxes the same height as all the other controls on the page?
Also I tried to select multiple text boxes to aligh them or make the same size, I remember I can do it in visual studio 2005 before, but now I cannot do it in 2008.
I did it be select one, and press ctrl button to select the other one, but the other one cannot be selected. Did I do something wrong?

I have an ASP.NET gridview where I allow the user to edit a record. I need to validate multiple fields as one. I need to require that the user either enter a first and last name OR a company name. All three cannot be blank. Most of the sample code I am finding does not address the text boxes only being visible while the gridview is in edit mode. When not in edit mode, the text boxes do not exist so
document.getElementById('<%= editFirstName.ClientID %>') throws an error upon page load.

Meaning only one of them can have a value, but not both.
I suspect one validation control can't handle both.

There seem to be about a zillion posts on similar situations, but I can't seem to find an answer in any of them. I've tried numerous techniques that I've seen, but nothing is making a difference. I have a Master page with an UpdatePanel with a ContentPlaceholder. In the content page I have a calendar. Above the calendar are LinkButtons that trigger a Command event to switch between Day Week and Month views. In the calendar DayRender event I am adding items to each day of the calendar. Items are pulled from a database. All items are contain within a dynamically generated div to help with layout. Each event that is added is a hyperlink that takes the user to a page where they can edit details of the event.
If there are more than 4 events, I'm adding a LinkButton with the text, "(more...)". I'd like that to trigger a Command event so that I can switch to the Day view of the appropriate day:
[Code]....
The problem is that, while the anchor tag gets generated with the proper text and ID, no href attribute is rendered and, as a result, nothing happens when you click "(more...)". I've tried switching to a Click event, but it does the same thing. (And I need the Command event to use the code I already have in place for some other buttons.) I've tried rendering it as an asp:Hyperlink and using ClientScript.GetPostBackClientHyperlink. That gives me a hyperlink, but I don't know how to get it to trigger so it results in the server interpreting it as a Command event and linking it to the proper event handler.

I want to create buttons and text boxs runtime and assigne to asp table.
When user clicks on button text box should be visible and user will be able to type some text and submit to server. This is nothing but something
like Blog. I am able to create asp table, button and testboxes but could not do visibility and events of buttons.
