Web Forms :: Handle Active And Inactive Items In The Dropdownlist?
Aug 23, 2010
It is a general ASP.NET questions. Many times some items in dropdownlist will become inactive (retired)or active again. It is easy to handle in the new records which use only currently active items. But how to handle the inactive items which need to be used to show history records. It bothered me a long time, not sure how to solve this problem efficiently.
I would like to know how to display active and inactive staff members in my datagrid. I would like to be able to have a default setting of the active members with a button or hyperlink saying "display inactive members" and when you click on "display active members" it will show the inactive members with the link saying "active members". There is a column in the Staff table called is_active with 1 or 0 in it.
I have a tabcontainer with three tabpanel. The first tab is always enabled, while the other two get enabled and disabled in the code-behind depending on some conditions.I would like to customize the header style of the second and third tab such that: - If the tabs are disabled, the header (title of the tab) font color should be gray - If the tabs are disabled, the header (title of the tab) font color should be blue. Currently, I have the following in my style sheet: `a.ajax__tab_tab{ color: blue; }`but this always sets the tab title font color to blue, regardless of whether the tab is enabled or disabled. This piece of code shows the conditions to enable or disable the tabs. Can I control for style here as well?
I am building for a class I am taking. I am familiar with Win forms, but I am not sure how to duplicate the same behavior in a Web Form. The 1st question I have is: I have a menu on my web form, but I am not sure how handle click events from the items on the menu.
this is my first post as you will easily see i'm quite new to this and am struggling. i have some working code that pulls user information from our active directory. the only way i've seen so far to display these results is to place it in a "For Each" statement.this can then be output to the page. however if there are lots of results this can take a while, so i was wondering if it was possible to be able to step through and handle the results by an index? here is what i have done so far:
[Code]....
the other issue i have is that i wish to be able to change the search criteria to the "Path" and then go to an idividual when clicked on.i have checked that this would work but cannot get my head around how i would make the result "Clickable" As you can see i have also tried using list boxes but was unable to format the results sufficiently.
i have a database table with lot of records > 17000what is the most efficient way to let user to choose between one of the records- 1 dropdownlist with all the 17000 record ?- 1 textbox with autocomplete and a webservice that return the list of the records ?
I would like to highlight (bold) and disable certain items in the dropdownlist for selection.
My dropdownlist is fed from a SQL table of countries e.g.
Europe -UK -FR -DE -AU
I need to heading "Europe" to be not selectable? the database has a column (selectable = 0) for those heading and I need to make them not selectable on the client side.
I see that dropdownlist has an "items" property to get the list of displayed items for a dropdown, but it doesn't seem to have an equivalent property for getting the "values" associated with the items. For example, I may have a dropdown that displays "High", "Medium" and "Low", but returns values of "H", "M", "L". How can I easily get that list of HML?
I have two DropDownLists; DropDownListStart displays the hours 09:00 - 19:00 and DropDownListStop displays 10:00 - 20:00. When the user chooses one of the hours in DropDownListStart I want the program to adjust what's shown in DropDownListStop so that the first hour shown is one hour after the hour chosen in DropDownListStart. How can I do that in code behind (c#)? An example: if the user choses 13:00 in DropDownListStart I want DropDownListStop to display only 14:00, 15:00, 16:00, 17:00, 18:00, 19:00, 20:00.
when I delete all records from the table it display this error messageon the line ddlIdOCRQ.DataBind()"Argument Out Range Exception was unhandled by user code""'ddlIdOCRQ' has a SelectedIndex which is invalid because it does not exist in the list of items.

I have a nested gridview and inisde a child grid there are several columns having dropdown and one add button. when add button is click a new row inside a child grid is created with an empty dataand previous row data have been saved in viewstate so that it can be bind wen add button is click to create new rows.My code is working fine when i dont select any dropdown list item and new row is also created but wen i select items from dropdown and click on add more button i get above error.
When add button is click
protected void ButtonAdd_Click(object sender, EventArgs e) { Button gv = ((sender) as Button); string[] ParentIdArray = gv.ClientID.ToString().Split('_'); int ParentId = int.Parse(ParentIdArray[1].ToString().Replace("ctl", "").Trim()) - 2; int RecordCount = ((GridView)GVMain.Rows[ParentId].FindControl("grdAddHotel")).Rows.Count;
DataTable dtAddHotel = new DataTable(); dtAddHotel.Columns.Add("CostSheetId");

I have a DropDownList with a list of orders. When an order is selected from the list I generate a GridView with details of that order. Within the GridView I call other databound controls and all works fine until I finish the orders in the DropDownList
I have tried to enclose the code within a if dropdownlist.items isnot nothing end if but it makes no difference
This is the code:
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound If DropDownList1.Items IsNot Nothing Then GridView1.SelectedIndex = 0 [code]...
