Web Forms :: How To Read New Value Of Textbox After Populating It With Session Value
May 12, 2012
I want to update record having image, and text. For this purpose I used select command in gridview control to fecth the record to be updated. then store these values in session. These sessions are used to populate a table in which record will be updated.then using update query values are updated...
but the problem is.... When I populate the textbox in the table with this session value… then it does not read new value entered in this textbox to update record and takes previous value.
(record does not update with new value… )
How I do this... i want to populate table with the record to be updated and then through update query , update record....
I am using VWD with a page that includes a formview and gridview. At the top of the page is a textbox, with and ajax calendar extender where the user selects a date.
The gridview is filtered on this date. I would also like to prepopulate a textbos in the formview insert template with this same date.
To speed things up for the visitor of my web page, I put a personalised dropdownlist in a session variable (as below).
The idea is that if the user is logged in and the ddl session variable is Nothing then it should be set here, and the next times the dropdownlist should be set from this session variable.
The session seems to be populated ok, but the resulting dropdownlist (ddlMenu) doesn't (it just becomes blank). I suspect that it has soemething to do with the way I try to assign it. No matter what I try I run into problems, saying that one thing is a one-dimensional array and the other thing a listitemcollection, or the like. What should I write in the last line?
If Session("aid") IsNot Nothing And Session("ddl") Is Nothing Then Dim ddlny As New DropDownList ddlny.Items.Add(New ListItem(vstr, "")) ddlny.Items.Add(New ListItem(kontrstr, "PageA.aspx")) ddlny.Items.Add(New ListItem(bstr, "PageB.aspx")) If dt IsNot Nothing Then 'dt is a datatable, populated elsewhere For i As Integer = 0 To dt.Rows.Count - 1 ddlny.Items.Add(New ListItem(dt.Rows(i).Item("name"), dt.Rows(i).Item("did"))) Next End If Session("ddl") = ddlny End If ddlMenu.Items.Clear() ddlMenu = Session("ddl") 'THIS IS THE LINE THAT SHOULD BE REWRITTEN.
I can get selected values from my first page with session. In my second page i want to populate product details side by side in listview with this values. How can i do it?
I am just trying to figure out a way to populate a textbox based on the results of two ddls. I have one table that stores the whole data...So an example would be
DDL1 - State DDL2- City
Textbox(Comments) - "Sometimes the comments would already be on the table...so i will like to populate the ones already in there based on the two ddl's
I want to write an independant class that can fill the fields in an HTML using asp:textbox. I have a class that can pull information from username and send it back to the webform. I would really like to use another, or possibly the same class, to take that data and send it to asp:textbox.text to populate the fields.
My issue is I just can't seem to find anything in my books, or online, that would help me let the class know the form is there, and that it has those fields inside the html code.
Are they objects that I could potentially pass into a new class constructor that I could populate that way?
After accomplishing this my next step would be to use this to create a class to send an email with some of the fields being passed from the form to help fill in the email.
1. textbox (Search for staff) 2. Dropdownlist( Search for department) 3. Listbox( Populate staff name based on textbox or dropdownlist)
I am able to populate the staffs indenpendantly according to what is written in textbox or dropdownlist. Whar i wanted to do is mix the population of staffnames from textbox and dropdownlist. In other words, when i search "sandra' in textbox and select a Department A , the listbox will show all the sandra from Department A only.
I have a Gridview that has a template field containing a bound textbox (fieldname is 'Status'). I have an extra column containing an update button, which is designed to update the db with whatever is in the textbox.
What's happening is that when I load the form, the textbox is blank, even though there is existing data in the fields. If however I click the update button, all the textboxes in the Status column update and populate with the correct data from the database. I guess my question is why would bound textboxes not populate until an update command is run?
I need to design a Textbox which fetches the values from database, as the user types in values in the Texbox. The fetched values should be displayed as autocomplete values... in a similar manner as google search box works...
I am getting an error "Unable to cast object of type 'System.Int32' to type 'System.String'."when attempting to loading data from a stored proc. My database code is
i am poupulating data from database which was saved using Rich textbox in vs2003 into a text box in Vs2005.But,i had problems when the data is populated.I am seeing some ascii characters as textbox doesn't know how to present formatted data.
i want to upload picture throw FileUpload control and then store it in session, after store in session i want to read it out to image control and insert to database.
I am having a text file in application path ~/Upload/txtName.txt.I am having some content inside the txtName.txt. I need to show the content inside the txtName.txt. to the Text box dynamically.
I have 4 textboxes. On which I want to show values from a database table which are readonly. After a button click event I have to show the updated values again.Two difficulties I have faced 1st to get four fields of data from DB than show those four data in specific texboxes.another is after doing some calculation showing updated data after a button click event.
How do I just get the first line of a multiline textbox? Either that or delete everything after "<br/>"? I tried something like this but it doesn't work:
I have a TextBox in a nested FormView that I want to use for entering a date. I have added a calender extender to the TextBox and I want to set TextBox to read only so that the date can only be entered by using the calender extender. This way I can avoid improper date formats.
The problem is that when I enter a new date and click the Update button, the new date is not saved to the database. I have done some searching on the WEB for a solution, and I found that "Page.Form.SubmitDisabledControls = True" is used in the Page_Load event to solve this problem. I have tried this and it does not work.
Another solution that I have seen is to set the control to readonly at runtime in the FormView "ItemCreated" event. I have been unable to access the "ItemCreated" for this FormView because it is nested.
This was working fine and then I was tinkering around and I can't figure out what I did to break it. When I stepthrough the debugger, the for each stmt cannot read values from the radiobutton list or the textbox, it only show "" for each. I double checked the id names between the code behind and the markup.
i am creating dynamic textbox onRowCreated event and its creating without any issue but the question is how to read value of created textbox when the use hit on update button?
I have gridview created dynamical and added text box to the footer so I can insert into the gridview but I'm using findcontrol but it saying the value is null.
