I'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 tables :
1- Builder
2- Project
Structure of Builder Table :
ID INT PK Autogenerated
Name nvarchar(50)
Structure of Project Table :
ID INT PK Autogenerated
BuilderID INT
ProjectName nvarchar(50)
Now i have a dropdown combo which is manually binded to Builder Table , what i want is that it would disable all those builders in the dropdown to be selected which are residing in Project Table.
I have a tag:
<asp:ListItem
CssClass="LabelCSS">Executive</asp:ListItem>
and I am getting the error message
Validation(ASP .Net):Attribute CssClass is not a valid attribute of element ListItem.
What attribute would I use for Css with ListItem?
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>
[code]...
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. In this ListItem Collection editor there are 4 properties 1) Enabled 2) Selected3) Text4) valueI really need to add some new properties such as "ImageURL" and "IsClear".

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:
,2,
2
1,,3
1,2,3
//accessing value
protected void getreportType()
{
SqlCommand cmd = new SqlCommand("SELECT * from reporttype", con);
con.Open();
CheckBoxList1.DataSource = cmd.ExecuteReader();
CheckBoxList1.DataBind();
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?

I have a DropDownList.
I need populate it with item collected in a List<ListItem>.
In my script, collector has been populated properly.
But I cannot populate the DropDownList. I receive an error:

if (myUser.aspnet_Roles.Any(r => r.RoleName == "CMS-AUTHOR" || r.RoleName == "CMS-EDITOR"))
myListUsersInRoles.Add(new ListItem(myUser.UserName.ToString(), myUser.UserId.ToString()));
}
uxListUsers.DataSource = myListUsersInRoles; // MAYBE PROBLEM HERE????
uxListUsers.DataBind();

View 2 RepliesIn vsw2005/ASP.Net 2 i have a formview used for project management; i recently added a new set of dates and a dropdownlist for the contact name. It is essentially a duplicate of another set of dates and contact. Both dropdownlists use the same sqldatasource, but the new one is throwing an error when the form changes to edit mode:
"'ddlInstall2Engineer' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value"
The error occurs even though I have a static listitem with appenddatabounditems set to true. Here is the markup for both ddl and sqldatasource (as you can see, other than id and name of field being bound to, they are identical):
<asp:DropDownList ID="ddlInstallEngineer" runat="server" AppendDataBoundItems="true"
DataSourceID="sdsInstallEngineer" DataTextField="Name" DataValueField="ID"
SelectedValue='<%# Bind("InstallEngineer_ID") %>' Width="150px">

How can insert new line in text of a Listitem?
I tried below code but not work..
HTML Code:
new ListItem() { Text = "part1<BR/>
part2", Value = "0" } ??
I have a simple javascipt which enables/disables some checkboxes when another checkbox ticked/unticked. This works fine, however, in some instances when by page is loaded my code behind disables the same check boxes. When this happenes my original check box nolonger seems to have any influence in enableing or disabling - there is no error and all the elements seem to be found by the javascript - it just doesn't enable/disable the checkboxes.
