Web Forms :: Textboxes On Form Not Showing Data From Dataset Row Item When Data Is There
Oct 8, 2010This procedure is call from the page load:
Private Sub ImportDataFromDataset()
This procedure is call from the page load:

I have the following DATASET:
Articles
Id
Title
Text
DateTime
I have some data on it.
Lets say for example i fill a dropdownlist with the articles, and the selectedValue is the Articles.Id .
I want to get for example, the Title of an article, that has ID=2, for example and fill a textbox with that data.
How should i do ?
I have a detailsview, template as follows:
[Code]....
Codebehind: creating dataset, getting data from sql with adaptor and filling into dataset object, then setting detailsview's datasource.
I add 2 button to above template to able to edit data at asp page, and added event handlers:buttons:
[Code]....
My question is, what to do inside the detailsview update event function to able to edit and update data. My method can be wrong too.
I have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx
[Code]....
[Code]....
Repeater.aspx.cs
[Code]....
Right now the problem is im not able to fetch the values of the textboxes present in the newly generated rows.

I'm a bit new to VB .NET programming. I was given a project to build a web page for our Shipping department to pull up some order & invoice numbers, based on an order number parameter.
Basically, what I'm trying to do is, when the user enters an order number, I want the web page to display the invoices & invoice dates that are associated with the order number.
I've put together some code already, but not sure it is actually working. The web page comes up in Debugging mode and it acts like it is pulling data from the Oracle database, but nothing shows up in the Gridview (which I bound to the dataset... I think).
[Code]....
Being new to VB, I'm guessing my code may not be totally correct. I've tried lots of things and done tons of searching on Google, but nothing I've tried seems to work. At this point, I'm not even sure if the dataset is being populated correctly or at all either. I'm a bit lost right now and could use some expert thoughts.
In case it helps, my dataset has one data table in it (dtShipData). My dataset class is sdDataSet. I added 3 columns to the data table and the gridview, manually. Not sure if should do that or not. I don't have any SQL behind the datatable itself...
I am using gridview. I Added checkboc under itemtemplate.My page works fine. i have set my page according 508 standards. It looks for associated control id for every textbox, check box..etc.
When i check my page by 508 standards its giving form lable is missing for gridview item tamplate checkbox. i tried adding lable inside item tamplate and i set the check box id as Associated control id for the label. eventhough its not going off that error. After setting some text my errors are resolved.

View 9 RepliesI have a basic web form with about 5 textboxes. One Textbox is "Date1" and the other is "Date2." Is there a way to set the value of Date1 = Date2 after the user enters a value into the Date1 textbox? I'm using Visual Studion and C#. I'm not much of a programmer, so the less technical the better.
View 11 RepliesI am retrieving data from a web serivce and storing the data into a dataset.
I'm then populating a gridview with the data from the dataset.
Before each row of data is displayed on the website, I need to check and make sure the user has proper permissions to view that data.
Can this be done with a gridview(or any other .NET data control)?
Or would I need to loop through the data manually, and then write each row out manually?

I will have some data binded to gridview.When i click on select i would like to display the data individually to textboxes
I m getting data into GridView. I want to display the 1st row data in some textboxes in the same page.
How to get the Values of 1st row and how to display those values in textbox.
i have a gridview binded to a database(MySql), with a column ID.now what i want is that when some clicks that ID(Unique) the data corresponding to that ID should be displayed in individual textboxes.
ie
1 Alok 25 9899898989 India
now what i want is if someone clicks 1 then all data should be displayed in databoxes assigned to all fields.
I am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?

View 2 RepliesI use a ItemDataBound for a repeater.But i use 2 kinds of linq querys to bind it.Some of them has a MerkID, and some doesnt have this item.So its easy i need to do this:
if(e.Item.DataItem.Contains("MerkID"))
{
//Code for linq query 1
} [code]...
So of course the if selection doesnt work, but how can i do that? I already tryed this:
DataRowView drv = (DataRowView)e.Item.DataItem; if (drv.Row.Table.Columns.Contains("MerkID"))
But that doenst work because he cant convert it to a datarowview because its a linq class.So what to do? Right now i use a try and catch, but there are better solutions i guess...
I have a page with textboxes and a button. I would like to dynamically load the textboxes with data that is in a detailsview on a page load or detailsview load. For example, ID, first name, last name. I find out how to do this on another page with a selected_indexchanged event with a gridview. See the code below. I'd like to be able to do the same thing but with a detailsview in the detailsview_load event.
Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.SelectedIndexChanged txtPK.Text = GridView1.Rows(GridView1.SelectedIndex).Cells(1).Text
txtFirstName.Text = GridView1.Rows(GridView1.SelectedIndex).Cells(2).Text txtLastName.Text = GridView1.Rows(GridView1.SelectedIndex).Cells(3).Text
End Sub
I am trying to create a page that will display data from a database after a search action by the user. So i currently have a textbox and button to perform the search function...then i want the data fetched to be displayed on several texboxes on the page (say there are 5 texboxes that I need to populate).how this can be done? Here is the code that I have come up with so far. I am stuck in trying to figure out how to bind the data to the textboxes. I also have my connection string in my config file and I have that code below as well..

I have a repeater control:
<asp:Repeater ID="rep" DataSourceID="XMLDSCompare" runat="server">
<ItemTemplate>
<h4><%# XPath("title")%></h4>
</ItemTemplate>
</asp:Repeater>
Now if its the first item in the total resultset, I want to add <div> to ItemTemplate control, if its the 2nd item, I want to add </div>
So output would be (not including table tags generated by repeater control):
<div>
title 1
title 2
</div>
<div>
title 3
title 4
</div>
<div>
title 5
title 6
</div>
How would I do this in the ItemDataBound event of repeater control?

I have a form with several textboxes. All of these have AutoPostBack="True".
My problem is that the focus disappears to goodness knows where after each postback. The behaviour I would like to enforce is as follows,
If the user hits the Enter or Tab key after filling in a textbox then the focus should go to the next field on the form (to be explicitly specified in my code).
If the user clicks on textbox X after filling in textbox A then the focus should go to textbox X after postback, even if it is not the next in the list.
In other words, I want the form to behave in the way that most users would intuitively expect.
I have Googled for potential solutions to the loss of focus after postback but the few that I have found were many years old and I am unsure that the advice is still relevant for ASP.NET 4.0. Some of these old solutions also appeared to be invalid for browsers other than IE. What is the current best practice for handling this issue?
BTW, VB.NET solutions are preferred though I will also be happy to accept C# suggestions (which I would run through a code converter). Note that I have a single sub in my code for handling the TextChanged events for all my textboxes. This means that I have to use the following code to work with the textbox that has called the sub.
Dim CurrentTextBox
As
TextBox =
DirectCast(sender,
TextBox)
If addressing the focus problem means that I have to have individual TextChanged event subs for each textbox then so be it, but I prefer the simplicity of my current single sub approach.
