Web Forms :: Finding Text Box In Dynamic Table Cell With Master Page
Jun 25, 2010
I recently built a table dynamically on a page.
this is how I pulled the value back to fill in the text box in the table. With no master page.
TextBox tb = (TextBox)table.Rows[i].Cells[j].FindControl("TextBoxRow_" + i + "Col_" + j);
tb.Text = Request.Form["TextBoxRow_" + i + "Col_" + j];
Now that I've added a master page to this things apparently have gotten more complicated. This won't fill the value for the textbox in the table cell that I want. I know the value still exists because if I do this
Request.Form.GetValues("ctl00$MainContent$TextBoxRow_" + i + "Col_1")[0]
Has the value that I want to put into that text box. I know the text box gets created because it's there when the page refreshes. But I can't seem to find that text box so i can put a value in it.
I have placed a textbox, dropdownlist and command button in a section of my master page. The textbox, named txtsearch, will be used to input a search string. The dropdownlist, named ddlsearch, will be used to specify in which field to search in the table, either part name or NSN.
Questions:
What VB code do I use to save the value entered into txtsearch as a search string? How do I pass that value to my entitydatasource? How do I tell entitydatasource to search in either the part name or NSN field based on the value of ddlsearch?
I am adding text fields to a page from the database. I set the .ID to match the record ID from the database. Of course becasue the text field is on the masterpage, when I grab the .ClientID, it is ctl00 contentMain$ctl00. what I don't get is where is my ID? If I set it to say AB how do I find the textbox by AB? I thought it should have AB in the ID somewhere. ID is nothing which I don't get either. I'm looping through the controls in a placeholder like this
For Each row In dtData.Rows() Dim c As Control For Each c In phTextRequired.Controls If c.UniqueID = row("CustomFieldID").ToString() Then
Again though what is in the row() is say AB but the id is way off from that.
My mission is to figure out how to hide a dropdown box, and I hope I will be able to receive some . My web form is set up like kind of a questionare, mostly yes/no, some N/A's for the answers in the dropboxes. I would like to make an entire question vanish based on the previous question being answered N/A. I have the web form setup using tables, each question occupying a cell.
I have an aspx page with a div containing an asp:Table with 1 row, 1 cell. From the codebehind, I read a user supplied text file and add rows/cells (vb). I would like my output to have indented text in certain rows. Example follows:
I have a control in a content page that I want to find the width and left attributes of the style. I am trying to find this from Javascript code that exists on the Master Page. How do I do that?
I'm starting with ASP.NET MVC (1.0). I have a problem to resolve. I have developed a web applicaton (an application of articles like e-commerce) with a head (logo and menu). I have defined the head (logo and menu) in the Master page (site.master). Now, I must display the number of articles in the head in a field (like the number of articles in the virtual basket in the e-commerce). I can read the number of articles in the data base (in the controller), but i can't integrate it in the master page.
I have a codebehind.vb for a master page from which I'm trying to find a hiddenfield in the content page. I was finding it like this without a hitch...
So it is time to use some pages i have to a master page.I have limited usage with master pages so i will write some concerns here so i could get some answers cuz i don't want to start breaking stuff on xmas days.
Of course i will give it a go on my own but it will be good to know what problems must be aware of before i start.If someone knows of them.
So i have a concern about page transfer.
I do a post and on the page to go to i use "<%@ Reference Page="~/thepage.aspx" %>"
Will this go on the master page or on the page to be transferred to?
Also i had an issue with the below command:
Dim result = CType(Context.Handler, _Default) .
Apparently asp is quite funny sometimes and it has blued out the code saying, eerrr, can quite remember but something like the page cannot be found or something.Haha.Very funny.I copy pasted all the code to a new page, deleted the old one and renamed and it worked.So if this happens if i embed the page to a master page, will the copy paste technique will work again or i need to modify the master page also?
Another concern is about the daypilot calendar(Gary? ) it's a heavy ajaxed page using panels,:UpdatePanels,ajax,javascript,server manipulation,SqlDataSources etc. I don't expect most of you to know this but will there be a problem by putting the daypilot design interface inside a master page.This page is so complex that i prefer not to use it inside a master page if i suspect that something is wrong.
Paypal concern.I have read somewhere that you cannot use 2 form tags and master page will give errors.However my approach is using a StringBuilder and doing AppendFormat to finally create an iconic form.So has anyone tried this to a master page?Will it work.
Viewstate.I use viewstate encryption when i use viewstate.Will it work on a page inside the master page?
I have a simple SiteMapPath in my master page like below. <asp:SiteMapPath ID="SiteMapPath1" runat="server" SkinID="SiteMap" Visible="true" /><br /> Also I use Web.sitemap and include all static sitemap pages. In my Web.config, I have this: <siteMap enabled="true"/> Currently, many pages uses this static site map for many projects and I'm not supposed to update the master page, but I need to have dynamic site map so that I can add query strings for each navigating pages.
I have a masterpage in that i have few static control , tree and menu , i am generating the tree and menu dynamically , that works fine , after that when i chlick any node, the content page lode perfectly ...but the dynamic control in the master page ( tree and menu )disapper , but all the static control are there , what might be issue , i am generating the tree in master page load event ,
[Code]....
this is my code in page load event , i am using VS2005 , IE 8, windows XP
I have a textbox and a button, and I trying to give the user a search option in the master page. The onClick event of my button is fine, but the textbox.Text property is always empty. I googled a little and fine many articles about accessing the Master from the ContentHolder, but I believe its no my case...
I have a web application that contains a MasterPage and a Web.sitemap file for the navigation. I am loading the navigation into an <asp:Repeater> control and I associating it with <asp:LinkButton>; something like this:
[Code]....
I have two issues:
Setting Session Variables: I'd like to set some session variables when any menu item is clicked.Dynamic Url: Once the Session variables are set, I'd like to set the url dynamically after the Session variable is set The thing is, I'd like to use the same aspx file for two different menu items, and I'd also like to set some session variables at the time of menu selection. I am aware that I cannot use the same url when I define the url in the web.sitemap file.
I am creating Dynamic Checkboxlist controls and adding them to a Panel. It works well when I do not have a Master Page configure to this webpage. Once I have a masterpage congifured.. I get a "Object Reference not set to instance of object" error on the Panel_Control.Controls.Add(Checkboxlistnew) line:
I have one master page that is used to gather information from a user. It contains asp.net labels and textboxes within a table. For example, the master page contains fields for Name , Phone, Address, etc.
There are content pages that are created to add to the information that needs to be gathered. For example, the content page, Loan Application, could ask for Loan Amount, LTV, etc.
In addition to this, certain content page forms do not need to show a particular master page field. For example, the content page may not need to ask for Phone.
The table rows are stored as public properties in the master page so I can hide them in the content page code behind.
public bool HomePhoneRow { set { trHomePhone.Visible = value; } get { return trHomePhone.Visible; } }
So, in the content page code behind, I have this:
Master.HomePhoneRow = false;
The functionality works perfect, but I don't like how the space is reserved on the page. You can tell that a row was removed. I've tried style="border-collapse:collapse" on both the <table> and <tr> elements. I've also tried to set the row height as a public property and alter that.
And in another page i am displaying the list of all the dynamic database tables. Here user selects table from gridview and the data is displayed to him in dynamically generated HTML Table with Dynamic textboxes. (This part is also running ok)
Code:
// Display data protected void getTableInfo() { int RowNo = 0; string NotCmd = "Select * From NTL Where InfoCode = @InfoCode";
[Code] ....
Now the problem is how to update the record in database through this dynamically generated html table and texboxes. When I run my dynamically generated update command, all the dynamic controls is lost in postback.
How to find the client id of a cell in GridView that is in edit mode. I need to attach javascript to the cells of the row that is currently being edited.
i have a master page with a tree view. i need to add a query string to the treeview and that value is on the page that uses the master page. all i want is for the treeview to navigate to the right page passing the clientID. so instead of this:
the value is in the txtClientID text box which is NOT on the master page. here is my master page and the page that uses the master page.master page tree view html code:
I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the heme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" />
Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this:
I have a page that uses a MasterPage. On this page, I have a DataList, which has a table. I assigned an ID to that table. I want to modify the properties of that table in my Code Behind. I'm having trouble accessing the ID using "FindControl". I've tried the following:
Dim MyTable as Table = DirectCast(DataList1.FindControl("MyTable"), Table) I've tried accessing it via the ContentPlaceHolder ID.. Dim ContentPlaceHolder1 as ContentPlaceHolder = DirectCast(Master.FindControl(ContentPlaceHolder1), ContentPlaceHolder) Dim MyTable as Table = DirectCast(ContentPlaceHolder1.FindControl("MyTable), Table).
I'm sure the answer is probably obvious, but I am not seeing it.
Is there a way in .net to display the text automatically when i type the first letter or word in a text box? I am looking for something like MS-Excel.. In MS-Excel, if the first word is given, automatically it displays the remaining texts, only if values are given previously.
My user filled a textbox with a text that was copied from Microsoft Word. This is a part of the text .
This system is - AUTOMATIC - and it is restricted
Look the symbols before and after the word AUTOMATIC. When I try to write this on a dynamically generated html page using the code bellow, i got this on the screen:
This system is â€" AUTOMATIC â€" and it is restricted
Code used to print the SQL Field:
[Code]....
The - symbol is not a minus symbol, but is a Word minus (-) symbol...
