Forms Data Controls :: Checking Null Or Blank Text Boxes Prior To FormView Edit Update?
Jul 9, 2010
I have a FormView that is loaded with a records from my DB. Some of the fields may be blank or null. I am trying to check the value of some of the text boxes to verify that the user has updated the fields prior to allowing a DB update from the Edit Template.
I can not seem to get the correct syntax on the if statment to check the value of the text box....
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 .
Is it possible to update and edit a record in Formview at the same time. Currently, the formview's default mode is set to Insert where users can add a new record to an SQL database, however, when that record is added I need that information to update another table all on one click. Is this possible with a stored procedure or a button that allows both?
I have created a Formview1 which have 3 columns Name, Status and Description. I just wanted to update display the Status and Description but not the Name. Can anyone give me any guidelines how I can do this.
I'm having a hard time solving what should (I think) be an easy problem. I have a formview defaulting to Editmode. One of my data fields is a binary image. How can I change the editItem template to allow a user to upload a new image into the binary image field?
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.
I have a strange issue with the FormView. After working through some issues getting the update to work (as this is my first experience with FormViews) I now have a new issue. After I perform an update, and the FormView updates and returns to read mode, if I hit F5 (refresh) the FormView performs another update to the datasource, despite the fact it is read-only mode and none of the fields on the screen are editable.
I would think that a refresh in read mode for the FormView after an edit would simply refresh the data from the database, not perform another update. Again, the FormView is in Read Only Mode, but a refresh is creating another Update event (which I can debug and see if I break in the ItemUpdating event). This only happens after I perform an edit, not when the page initially loads.
Is there one simple test that a person can do that covers all options where there could be a null, or "" value. When I google, I see so many options. I see:
if txtBox1.text IsNot nothing if txtBox1.text.toString isNot nothing if txtBox1.text <> "" if txtBox1.text.toString <> "" if isNull(txtBox1) Is there on test that can cover them all?
im using gridview to read data from datasuorce(my access) and im editing data using 'enable editing' from smart tag(in design window .aspx), now i want to change the edit text: edit(i hav named it as edit) to 'view' for one particular user whose name:'sunil'?
this is my table(in my access layer and calling this data through datasource of gridview):
I've been pickling my brain trying to do this for a couple of days but to no avail. I have the following in "FormView1" which I'm just using in insert mode:
I'd like the contents (i.e. whatever the user wants to insert) to be passed to a method where it will be checked against any existing values in the database.
I want to display a blank text box if the date in the table is null. Any ideas on this using MVC 2 RC? 1/1/0001 12:00:00 AM displaying for Null DateTime in Html.TextBoxFor(model => model.IssueDate)
User enters values into text boxes (personal information etc.) and then presses a save changes button. The values in these text boxes get stored in an SQL database. The problem I have is that when updating the database using the values from the text boxes, the page refreshes and the values in the text boxes are lost (or rather they return to the values that are already in the database as the data from the database is loaded into the text boxes on Page_Load). When I update the database using valuse stored in variables it all works fine. What is the best way to update with the values from the text boxes?
I have a custom validator which validates three text boxes. my code is,
[Code]....
I fill in all the three textboxes.it still gives me the error message to fill in all the boxes and does not submit the page even when all the three boxes are filled.
have created a gridview with input text boxes inside which can be added by the user.
So in order to populate the gridview on form load I use grdView.DataSource = PopulateDT(); this.grdView.DataBind();
Now is there a neat way of retriving the data content after the user has entered data from the gridview and store as a datatable. The only way is doing a for next loop which i think its time wasting.
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:
[Code]....
...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?
AchFile |-> FileHeader(At this when i click on this i will have the text files associated to that ) |-> FileHeader7.6.2010.txt |-> FileHeader7.7.2010.txt and so on
Now when i click on the text file i am displaying the content of text file in a data grid...
Now what i need is when i click on data grid i would like to display those values in a form in appropriate order.
This is what i have using VS and VB: formview that is bound to a sqldatasource. In the formview i set up three panels and the visibilty is controlled by three buttons. I want to be able to click the edit link button and have the panel that is visible in readonly mode be the one visible in editmode
I have to create some code for my website which will bring data from a database into my specific boxes.
