View 1 RepliesI've got a DropDownList in ASP.Net that has a ListItem that requires being disabled... but I DON'T mean Enable="False". And I also don't want to disable the entire DropDownList, just one specific ListItem. What I'm talking about is written in HTML as disabled="disabled", like so...
<option disabled="disabled" value="-1">Disabled Option</option>
how to do this in ASP.Net?
I have two listitems and the postback and run a function.

I am doing account creation process which is containing 5 forms/ screens. On screens user at any screen can click previous button and go to previous screen and change data (but sure it cannot be done on 1st screen, as there is no screen prior to 1st).
If I redirect user to previous screen all data is washed. I am even clearing form. For this I will have to fetch data back from db.
Can there be a way that I may not have to get data from db and data previous form may not be cleared and user can edit anything ?
I have a report with a line chart that displays customer data. The dataset has year, month, customer, and purchases. The data category group is by year and month. The values are purchases. The series group is by customer with the data sorted in decending order by purchases and a filter of the top 10 purchasers. This works fine as intended.Now I'd like to display just one of those customers on it's own seperate chart. Since I cannot use RowNumber in the filter, how do I accomplish this (i.e. I want to show "series 1" on a chart, "series 2" on another chart, "series 3" on another chart and so on).
View 2 RepliesI have 3 columns of data that get returned from a stored procedure. Date, Error code,and Quantity. On one day we can have 8 different error codes, with different quantities.For example on the date of 18 Nov we had error code 101 = 24, error code 102 = 36, error code 103 = 4, etc. I am trying to display the different error codes in columnswith their quantity by date. There will be multiple columns for a given day because the error codes range from 101 -124. How can I display this? I currently have Just oneat a time being display based on which the end user picks.
If DS.Tables.Count > 0 AndAlso DS.Tables(0).Rows.Count > 0 Then
ErrorCodes.DataSource = DS
ErrorCodes.Series("Exceptions").XValueMember = "Error Date"
ErrorCodes.Series("Exceptions").IsValueShownAsLabel = True
ErrorCodes.Series("Exceptions").YValueMembers = "Total"

I have a RadioButtonList with two ListItems included:
<asp:RadioButtonList runat="server" ID="optRollover" OnSelectedIndexChanged="RolloverOptionSelected" AutoPostBack="true">
<asp:ListItem Value="0">100% </asp:ListItem>
<asp:ListItem Value="1">Less than 100%</asp:ListItem>
</asp:RadioButtonList><br />
On the first ListItem I need to have a label that displays some text from the code behind of the page. Logically it seems to me like I would be able to do something like this: 100% Obviously this does not work because I am getting an error: The 'Text' property of 'asp:ListItem' does not allow child objects.
I have a databound dropdownlist, bound to an object datasource. I want to have a default value of "None" inserted at the top of the list and I would like to do this declaritively if possible. After much googling I came up with the below code. However it does not display my default item. I was under the impression that setting the AppendDataBoundItems to True would solve this, however it hasn't.
<asp:DropDownList runat="server" ID="ddl" DataSourceID="ldsCompany" DataTextField="CompanyName" DataValueField="CompanyId" SelectedValue='<%# Bind("CompanyId") %>' AppendDataBoundItems="True">
<asp:ListItem Value="DefaultValue" Text="DefaultText"/>
</asp:DropDownList>
I have an asp:RadioButtonList and want to declaratively bind the value to an enumeration. I tried using this type syntax:
value = <%# ((int)MyEnum.Value).ToString() %>"
I get an error list item does not support databinding.
I am trying to convert a ListItemCollection into a ListItem[].
Here's what I have in my code.
ListItemCollection rank = new
ListItemCollection();
rank.Add(new ListItem("First", "1");
rank.Add(new ListItem("Second", "2");
ListItem[] rankArray = new
ListItem[4];
rankArray = (ListItem[])rank;
Does a collection in C# .NET treats it as an array or another type of collection? I'm a bit confused on collection and an array.
I am working on to create a custom control inherited by CheckboxList control. We can add items from ListItem collection editior at the design time.

View 3 RepliesI had a requirement to pass data between pages in my application.I have a Page A where user will input some data and on submit User will be redirected to Page B where again user will enter some more data and on submitting user will be show a confirmation in Page C after doing some calculations and data saving.Following is the idea I was trying to use:
PageA.aspx:
[Code]....
In Page A Codebehind file I am creating following public properties of the inputs to access in Page B:
[Code]....
In PageB.aspx:
using previouspage directive to access page A public properties
<%@ PreviousPageType VirtualPath="~/PageA.aspx" %>
[Code]....
In Page B Codebehind file I am creating following public properties for the inputs to access in Page C:
[Code]....
in PageC.aspx:
using previouspage directive to access page A public properties
<%@ PreviousPageType VirtualPath="~/PageB.aspx" %>
[Code]....
Page C code behind file:
[Code]....
Postback is working fine from Page A to Page B, but when posting data from Page B to Page C, it is automatically redirecting to Page A.
I am not getting any kind of error or anything. page is simply redirecting to Page A. One reason as I understand is that when I post data from Page A to page B. Page A life cycle is executed and Page A becomes null.But when the data is posted to Page C. why the PreviousPage property is checked for Page A?
I want to create multi series asp.net chart in dynamically.I am new one for this concept.
View 1 RepliesI am creating a column and line chart in the same chart using reportviewer 2008.
The chart got two y series 'Number of product order' as column chart and label on left side of chart (unit number count) and total value of orders as line chart with label on right side of chart (unit $ value). Month is on x axis. I am wondering whether it can be done in reportviewer.
I'm currently developing a website that shows multiple charts that I build using data from SQL tables. I've used and followed Scott Mitchell's tutorial [URL] and K. Scott Allen's ChartBuilder class [URL] and all works well.
However when have two series that I want to show on the same Chart, if one set of data does not have all of the X values the other series does, the chart blindly puts all the data on, ignoring trying to match the X values of the other series, therefore mismatching the X values when the chart is shown.
I know that I can fiddle the data so that both sets of data have the same X values, however I'm trying to make the class handle anomalies in the data so that I don't have to worry too much about the data.
I have a large application in which I have lots of Submit - Delete - Cancel - Add and .. buttons. All of them use a same .Button CssClass.
I decided to reach the interface so that I want to differise buttons interface.
How to Apply a CSSClass to a series of similar objects with a different ID
I should Have similar Delete / Submit / Cancel or ... Button interface all over the application
All of the Delete button id are btnDelete and the same for the rest. (btnSubmit - btnCancel ...)
Note that they are Asp control so that only the last part of their name are btnDelete or ... and before Name, you have a client ID like (MainPage_MainControl_TheSimpleForm_btnDelete)
I'm going through the ASP.NET chart controls WebSamples project but I haven't found what I'm looking for yet. So basically if I had a standard bar chart with data such as below:
John - 68%
Fred - 75%
Mary - 32%
Anne - 88%
Displaying it in one series with names as the x axis and percentages as the y, is there anyway to change or highlight the bar colour of just one, so say all the bars in the series are blue but I want to programmatically change mary's bar colour to red. Is this possible?
I'm trying to programatically add a series to a Dundas TreeMap but I'm getting a Object reference not set to an instance of an object. error. This error looks to be a bug in Dundas, but I was wondering if anyone has tried/managed to do this?

I have a RadioButtonList with three ListItems, like this:
[Code]....
TrueRuleCondition, FalseRuleCondition, and CustomRuleCondition are protected constants in the code-behind file that I want to use as the values for my listitems. Unfortunately, the values get treated as literal values instead of having the values of the variables inserted. Does anyone know of a way to do this or why this doesn't work as I expect it to?
