I have a sample xml as;
<?xml version="1.0" encoding="iso-8859-9"?>
<DropDownControl id="dd1" name="ShowValues" choices="choice1,choice2,choice3,choice4">
</DropDownControl >
I need to create a UI representation of this XML using XSL. I want to fill the drop down list with values specified in choices attribute.
As I kept my fetched datatables into session and accessing it on another page there I am
wroking on datatable to fetch only distinct values of particular column to assign to dropdown list.
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I have a Detailsview grid with an SqlDatasource, this DVG is only going to be used to insert records. The primary purpose of the DS is to populate a DDL control in the insertItem Template that I created my code is this:
[Code]....
The DDL control populates correctly, but when I try to modify the INSERTCommand property in my DS, I try to assign the value to my parameters "TesterID" and "TesterDate" but the only options for controls to pick from, is the DGV but not the DDL in it. I assume it has to do with the InsertItem template but even if I reset it I still cannot pick the textbox as a control that would give the value to my parameters.
I did find a workaroun by build a public method and calling it in the onclick event of the insert button but looks like I have to create another connection to the database which to me seems unnecessary since I already have a DS and everything. how can I do this without having to use my method. here is my method just in case.
[Code]....
n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript">
function NextClicked() {
var _ddlStatus = document.getElementById("<%=ddl.ClientID%>");
var _selectedIndex = _ddlStatus.selectedIndex;
var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) {
_btn.ValidationGroup = "G1";
}
if (_selectedIndex == 2) {
_btn.ValidationGroup = "G2";
}
}
I wanted to add values to drop down list dynamically, How can I do that?
View 4 RepliesI have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
View 2 RepliesI'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).
The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...
I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.
I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId
I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:

I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.
The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.
The "making the GridView row display it" part is the one that's giving me a hard time.
What's the best way to do this?
