Forms Data Controls :: Dynamically Added Text Boxes Disappears After Page Refresh?

i am using above code to generate dynamicaly textbox into grid view. I have 3 fix coloumns from database which i fetch at start of code.
Then i assigned it to datatable. in datatable according to Listbox item count i added more coloumn as per listbox items count.
then that datatable i i gave as datasourse to gridview. Now i inserted dynamicaly textbox to gridview in respective coloumn.
But after refreshing page all textboxes disappears....
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 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.
I've created 3 buttons, first button is to load the values in textboxes added to placeholder. Then button2 is to extract the data from button 1 and display out. Now the 3rd step, I want to edit the values from the textboxes, after edit, how do I grab and display out the new values in label and textboxes?
Code: Partial Class _Default Inherits System.Web.UI.Page Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim x As Integer = 1 Dim message As String
Really getting better with VS, but I've mostly been displaying data. I'm on a new project and now and I have a lot of data entry forms to create. I created a form to enter data into an access db and got it working. I thought it would be cool to add an edit button that fired a gridview to load on the same page, under my original forms, so that that they could load up the data and edit or delete mistakes. But when I try to update the gridview, it also tries to post the original forms (text boxes), which fail because there is no data in them, and I get an error.
What is the proper way to handle this in asp.net? I'm sure this is kind of a common issue. I've done some searching, but the search terms, like forms and gridview, are kind of generic and I'm not coming up with anything useful. I just need a more experienced person to point me in the right direction and I'll get it figured out.
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.
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'm new to ASP.NET. I 'm trying to figure out how to make an HTML/ASP page where a user puts in data, either in text fields or selection boxes, and on clicking a submit button all of there selected data gets dropped either into a Access 97 Db or an excel spread sheet. Are there any examples out there of this? Is there a place that has already created this and I can just look and the code and figure it out for myself?
I'm trying to make a form where the text boxes and titles for each box are created dynamically based on how many array values there are. I have tried a repeater but am a little unclear on how I can get the texbox to bind to one area of and the title to bind to another. This is what I have so far:
...and this is the code-behind with an associated array, arr1:
// Bind Array to Repeater rep1.DataSource = arr1; rep1.DataBind();
This works and adds values where container.dataitem is but how to I make it add one set of array values there and another set of array values where the *x* is?
I have to create some code for my website which will bring data from a database into my specific boxes. I have a map on my site which on click of a hotspot, a page will pop up showing a smaller map and the data underneath it. The data will be in text boxes. How do I get the data from the database into these text boxes?
I have a gridview in my aspx form. I have used template column & in that created a table. In the table of the Item template , I am displaying some fields. My requirement is that when I click on any row, the correspoding data should be placed in proper text boxes. Each row in itemtemplate has a unique id called UserId.
i have a grid view and check box in it. and there are 5 columns in it. user name, first name, lastname city and ph no. and 5 text boxes... and a edit button NOW when i check any checkbox and press EDIT button i want the entries in grid view show be entered into text boxes.
I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then Dim ddl as DropDownList FillStateList(ddl) e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
I am adding linkbutton dynamically (actually above snippet tells what I am actually doing, in reality TableRow and TableCell are added dynamiccally). My problem is, I am not setting height of linkbuttuon which will added dynamically. I have no idea what text I have to add to linkbutton.
What I want, after all the link buttons are added, iterate through each added lin button, get the height of each linkbutton, store the max height, then re-iterate throgh the link buttons and set the height of each link button to max height.
