View 3 RepliesI am creating a html table from a list collection. I am able to create the table, but I am not able to group the related items and add into a single table.
[Code]....
I have 3 items in the list collection, in which Student Name is same for 2 items.
Now I am getting 3 tables. I want to group the student Name and get a single table for unique student name.
This is my list collection:
Student ID Student Name Mark1
1 John 25
2 Mac 22
3 John 24
I am getting 3 tables now, but i would like to group the student Name and then get a single table for John having his marks and another table for Mac.

View 3 RepliesI have a tag:

I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.
There are some objects contained in each of those objects... for instance there is an Address object.
object.Address.Line1;
object.Address.Line2;
When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:
"A field or property with the name 'xxx.xxxx' was not found on the selected data source."
I want to know that how i use the collection class for storing some data and save it letter in the data base.
View 4 RepliesI have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.
These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:
(in case of updating textbox.text):
[code]....
However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.
I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?
View 1 RepliesI'm using HttpModule to capture requests to the web server. Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.
View 4 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.
<asp:RadioButtonList runat="server" CssClass="ccsw" ID="ccsw" AutoPostBack="true" RepeatDirection="Horizontal" OnSelectedIndexChanged="UpdateCharges">
<asp:ListItem Text="Credit Card"></asp:ListItem>

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.
How do i databind from database into listitem?

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?
I am using jquery and c# to dynamically set a radiobuttonlist listitem to selected. I want to create a reset-type button to reset the radiobuttonlist selected item back to the first item in the list. jQuery/jsTree function currently reseting textbox and hidden field:
$('#ContentPlaceHolder1_hfNodeID').val('');
$('.txtPage').val('');
$('.rblContentTypesGetAll').val();
$('.contentPageForm').show(),
.rblContentTypesGetAll is the radiobuttonlist i want to reset (or select the top most listitem).
HTML of the form:
<asp:Panel ID="PagesForm" CssClass="contentPageForm" runat="server">
<asp:HiddenField ID="hfNodeID" runat="server" Value="" />
<table>
<tr>
<td>Page</td>
<td><asp:TextBox ID="txtPage" CssClass="txtPage" runat="server" /><span class="validate">*</span><br />
<asp:RequiredFieldValidator ID="rfvPage" runat="server" CssClass="validate" ControlToValidate="txtPage" Display="Dynamic" ErrorMessage="Page Name Required" ValidationGroup="page" /></td>
</tr>
<tr>
<td>Content Type</td>
<td>
<asp:RadioButtonList id="rblContentTypesGetAll" CssClass="rblContentTypesGetAll" OnLoad="rblContentTypesGetAll_Load" runat="server" >
</asp:RadioButtonList>
</td>
</tr>
<tr>
<td> <asp:Button ID="Submit" runat="server" OnClick="PageSubmit_Click" Text="Save" ValidationGroup="page" />
<asp:Button ID="Cancel" runat="server" OnClick="Cancel_Click" Text="Cancel" />
</td>
</tr>
</table>
</asp:Panel>
I must be doing something wrong here but I can't find an easy way to get this to work. Imagine the following code:
<asp:RadioButtonList ID="MyRadioButtonList" runat="server">
<asp:ListItem Value="<%= CompanyName.SystemName.Constants.PaymentFrequency.FREQUENT.ToString() %>" Text="Yes" Selected="True"></asp:ListItem>
<asp:ListItem Value="<%= CompanyName.SystemName.Constants.PaymentFrequency.ONCE.ToString() %>" Text="No, Just do this once"></asp:ListItem>
</asp:RadioButtonList>
But it doesn't compile the statement before it renders the page. So if I get the selected value of this radiobuttonlist it contains something like "<%= Compan... %>" instead of what my constant defines.
i want to show checkboxlist listitem checked according to option value saved in DB like this:

//accessing value
protected void getreportType()
{
SqlCommand cmd = new SqlCommand("SELECT * from reporttype", con);
con.Open();

con.Close();
//getting previous checked items
SqlCommand cmdx = new SqlCommand("SELECT report_type from projects where serial_no='" + Convert.ToInt32(Request.QueryString["id"].ToString()) + "'", con);......
but it is only shows checked item of column which have single value without comma means like "2" otherwise not shows any selected listitem from any colums
I wonder if there is a simple way to insert a new ListItem between 2 existing items of a dropdownlist?
