DataSource Controls :: SqlDataSource Can Bound To Text Boxes?
Jan 31, 2010
I have a sqlDataSource to populate a grdiview ( simple ) . When I set the sql control to a stored proc that has 4 parameters and person a select * from table ignoring the paramaters it doesn't work. No rweturned results.
I need to develop a custom data-bound control which will contain, few text-boxes, drop-down lists, labels, and other standard web-server controls. And, I want to be able to load this control from a web page on button click. When the user enters any data to any of its child controls, i should be able to save, and also retrieve when the data-bound control is loaded again. Also, the data in the child control should retain their value on postback. What approach should i follow?
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 .
when need to insert into Text.boxes details from user (name,e-mail, e.tc.) and to get record of it into DB on other page. I try to get after pressing Submit btn:
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.
This seems so very simple yet I am very stuck. Following some articles on the web, I came up with an ASP.NET web app page that is all declarative (no code behind) yet when it produces NOTHING I feel so totally stuck about what I've done wrong. Here is the entire little page:
I have a series of dropdownlists on webform in ASP 4.0. The first drop down is filled upon load, and then when a user selects a value from that list, it populates the second dropdown. To accomplish this, I have a SQLdatasource with a parametersource of the first drop-down list control. This works great, except when a user changes their selection from the first drop down. It performs the query, but then adds the list of items to the ones that were already there from the previous selection, instead of replacing it with the new data. Here is the code:
[Code]....
Do I need to do something on selectedindexchanged to somehow "clear out" the previous datasource? I can't find anything about this online, although one person seemed to suggest it was related to using a master page. (which I am using).
I have an aspx page with 2 controls on it - a GridView bound to a SqlDataSource control.Am I correct in thinking this is 2-tier ?If I were to replace the SqlDataSource with an ObjectDataSource, and make the database connections/calls/queries via a class in the App_Code folder, this would be 3-tier, right ?
I am trying to populate an (editable) gridview in ASP.NET with a table from SQL. I have a SQLDataSource set up for this. I also need to have this gridview be filterable based on parameters entered in textboxes. I have tried using ControlParameters for this and it works but the problem there is when all textboxes are empty I want it to display all results in the gridview. What it does is display nothing because no entries have parameters that equal "". Is there an easy way to do this that I am missing or is there a better way to go about it other than a SQLDataSource?
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?
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.
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.
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 have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?
Dim objDatabase As New database objDatabase.OpenSQLConnection() Dim objAdapter As SqlDataAdapter Dim objDataset As New DataSet Dim objAdapter1 As SqlDataAdapter Dim objDataset1 As New DataSet Dim objAdapter2 As SqlDataAdapter Dim objDataset2 As New DataSet
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....
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....
I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.
