Web Forms :: Coloring DropDown ListBox Items?
Sep 29, 2010I have a situation where some dropdown listboxes contain some items, then there's a separator line, and then there are more items. The ones above the separator line reflect the "commonly used items". To better highlight these I was using code like this to individually color those specfic items:
foreach (ListItem item in ddList.Items)
{
if (item.Value == "-1")
unAssigned = true;
if (!unAssigned)
item.Attributes.Add("style", "color:#5558ff");
}
This code works fine EXCEPT that once a PostBack occurs then the highlighting disappears. The items in the dropdown listbox remain (without repopulation) but not the highlighting.
I'm curious why this is happening and whether there's a way for the highlighting to "stick" short of calling this code from the Page_Load event handler every Postback?

AJAX :: How To Update Listbox Based On Dropdown Value / Unable To Use Cascadingdropdown
Mar 15, 2010i have a religion dropdown1 , on this selectedindexchange i have to populate castes into the listbox(not dropdownlist).
i am unable to use cascadingdropdown as it is tightly binded with dropdowns.

Religion
<asp:DropDownList ID="ddlReligion_RS" runat="server" TabIndex="6" onchange="GetCastes_RS(this.value);">
</asp:DropDownList>
<br />
Caste
<asp:ListBox SelectionMode="Multiple" ID="lstBxCst_RS" runat="server">

//js function
function GetCastes_RS(relgnID)
{
abc.BLL.Services.AjaxService.GetCastes(relgnID,
function (resp)
{
var ddlCaste= document.getElementById("<%=lstBxCaste_RS.ClientID%>");
ddlCaste.length=0;
var castesList = resp;
alert (resp);
if(castesList.keys.length >0)
{
for(var i=0 ;i< castesList.keys.length;i++)
{
op=castesList.keys[i];
ddlCaste.options[ddlCaste.length]=new Option(castesList.values[i],op);
}
}
},
function(val)
{
alert(val.get_message());
}
);
}
i could call the webmethod, but i am getting this error in javascript.

.NET Gridview InVB - Enable Or Disable The Textboxes And The Dropdown Listbox If The Row Is Not Selected
Mar 9, 2010I have a Gridview that has a button at the left hand side representing the row number. The Gridview has two textboxes and a dropdown listbox as templates.

C# - ListBox - Value Being Set To Text Field?
Mar 3, 2011When adding list item the Value field is being set to the Text field. Initially I though the problem was related to the input parameter for the primary key ( group_type_id ) as it is configured as OUTPUT variable.
Interesting enough, when I Watch all of the values, everything is correct.
So for example, I'll watch these:
ddr["group_type_name"] comes out as "Dept"
ddr["grouptypeid"] comes out as 4
When the item is created however,
itms.TEXT = "Dept"
itms.Value = "Dept" <-- THIS IS THE PROBLEM
I'm at a loss why the listbox values are being set to the text values when I can clearly see the data reader values are correct. ?
