Web Forms :: Loop Through Database Entries And Create Text Box For Each One?
Jul 14, 2010
I am currently working on a project where I am trying pull a list of entries from an Oracle database depending on a selection that is made by the user via a Drop Down list. Then I want provide a user with a list of options that they can select that is related to the drop down option that they have selected. For Example:
First Drop Down from database: Honda, BMW, Ford
If user selects:
Honda -- options that are available in the separte table in the database for this entry are -- Type, Engine Size, Colour
BMW -- options that are available in the separte table in the database for this entry are -- Colour, Wheel Trims, Extra's
Ford -- options that are available in the separte table in the database for this entry are -- Extra's
What I wanted to do is have a form displayed to the user where thy can say select a car eg. "BMW" and then on the change of that drop downs index the site will do a call back and retrieve the entries for the BMW options in the seperate tabel, these being Colour, Wheel Trims, Extra's. Then it will put these details in a DataSet and then i wanted to create a new text box or input field for the users to enter details in. I have tried the below code with no success as I get an error on my for loop of looking through the options DataSet.
I am getting an error whenever I try to get the first character from a textbox control when nothing was entered into it. So, I need to be able to check if there are any entries in a textbox before trying to get the first one.
I would like to find out if there is anyone who would know how to read from a database then returns the same number of records that a stored procedure returns and display those records on the webpage there after pass the ID of the record to a variable to another stored procedure that displays the data related to the record that was clicked, I tried doing this in a asp.net repeater but I can't seem to be able to reference the controls inside the repeater.
<Repeater HTML Code> <%@ Page Language="C#" AutoEventWireup="true" CodeFile="OpenLogs.aspx.cs" Inherits="OpenLogs" EnableEventValidation="false" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
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 want to show just a 8 entries pro time, and above the table make some kind of navigation (like 1 2 3 4 5 ..) and if i need to see next 8 entries I#m clicking on the number 2, i see them. I dont know how can i do all this.
i working with mvc, and i want too that this solution is dynamic, that by more entries automaticly will have longer navigation 56 enties = (1 2 3 4 5 6 7).
I am using the built in database with the tables (i.e. membership, users, etc...). I created my own table (relationships), but when I try to create a row that uses the same email address it says "cannot create duplicate entries". I am not allowing duplicate email addresses in the membership table. That did not work because I couldn't convert System.Guid to long. So, I decided to do it by email address. I changed idRequester to requesteremail and the same for receiver. However, when I try another record with the same email address in either field, it does not accept it.
I'm wondering how to make a column that counts the number of entries like each entry that i made an is given an individual numbern the SQl Server it self
I am working on an update to one of our sites. This version will have unique behaviors based on the host name in the request. In order to test this behavior, I modified my computers host file by adding entries that point back to my computer.
Everything seemed to be working fine, until I started working with the Session object. I discovered that after each request all my session variables were lost. Further investigation revealed that each response from the server contained a new SessionID.Why is that?I was able to hard code some flags to complete my testing using 'localhost' for requests without any problems.
where each entry has some HTML text and an associated Name and ID.
What I want to do in ASP.net C# is to list each of these entries on a page in such a way that the HTML text should be displayed exactly how it is meant to be (e.g. <b>test</b> should show 'test' in bold) and each entry should be editable. When the Edit button is clicked on an entry, the HTML text should be replaced by a textbox with the text inside it so that you can edit it and save it.
For example:
FOOTER --EditButton--
TEXT test
Now I am not sure on what is the best way to do this. Should I use a repeater with an ItemTemplate for each entry? If I use a repeater, and an edit button is clicked, how do I know which edit button is clicked and how do I know which textbox to display the text etc?
I have to create a text box where if user will enter something it should show the values from database like google shows.e.g If i press a it should display a if i have entered AJ it should show all the list which start from AJ.Same like google.
I have entries for an enumeration stored inside a database table with only the following fields: ID and Name. I want to show the values stored inside this table inside a DropDownList on a form. The user then chooses a value and submits the form.
I found a way to easily create a DropDownList from an enumeration (although it would probably be best to just populate the DropDownList with the Name fields of all the records in the table). However, I haven't found a way to later bind the DropDownList in the form submission to an integer value to put into the database (FK - PK) with the other form values.
is it possible to fetch DropDownList content via AJAX and have it be put into the DropDownList and into the SelectList in the ViewModel (with both the ID and Name parameters)? I want to selectively fetch content based on an input the user makes and I want the ViewModel to then be filled with that fetched data.
I want to change color of each row in a listview based on a data which is stored in database. I've written following code but I don't know by the help of which object I can access to markup property of listview :
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e) { if(e.Item.ItemType == ListViewItemType.DataItem) { ListViewDataItem dataitem = (ListViewDataItem)e.Item; int policyid = (int)DataBinder.Eval(dataitem.DataItem, "policyID"); if(policyid == 3) //what should I write here to change the corresponding row's color? } }
I have a dropdownlist whose values are int (actually they are string basically but they can be parsed. they are 1, 2, 3, 4, 5.. etc)
I want to create textboxes acording to the number of dropdownlist selected value. Lets say drop down shows 3 and I wanna create 3 textboxes. how can I do that.
OK I'm a total noob so bear waith me. I'm using the pubs database. I want to add several gridviews to my page in the inside of a for loop. Here is my code so far:
[Code]....
In the foreach loop, it is iterating through the publisher's tables rows, and I wamt it to query the titles table to find all books that have that publisher id and create a gridview out of it. In the code above I am not getting it right. I need multiple GridViews, one for each iteration of the foreach loop. How do I do this?
My question is, is there any benefit to instantiating a new userDetails object in every loop, or can this be created outside the loop and title, forename and surname just written over with every pass of the loop?
I've got a while loop that's doing some stuff, and what I want is for it to create a new array each time.
while(condition){ //do some stuff //create an array x[] //amend values in array //save as new array each time until loop finished }
Actually i need to store the comma separated values of different datatypes in an array using split.And then i hav to sort these values comparing zeroth position element of all rows.
i want to receive some data from my database and in a while loop. i use this code in the while loop
Code: Dim sqlda As New SqlDataAdapter() sqlda.SelectCommand = New SqlCommand() sqlda.SelectCommand.Connection = con sqlda.SelectCommand.Parameters.Add(paramar(0)) sqlda.SelectCommand.CommandText = "select images,creationdate,dimosieyseis from t_accounts where UserName=@un" Dim ds As New DataSet() sqlda.Fill(ds)
if i open and close the connection it becomes slow. if i use a general con and not open and close it then i receive an error
"There is already an open DataReader associated with this Command which must be closed first. "
then i tried to resolve this error with
MultipleActiveResultSets=True that resolves the problem but it is not faster because i think it does the open and close of the connection automatically
I have a query that returns a pretty big result. I want to break the big set into several smaller sets to pass into a function. If i had a 100 records returned, how would i get 10 datasets?
