but it did not work, it does validate all the time,
have a one field webform (Is an "Enter Your Name") field that writes it's data to a table. (Table 1)
I would like to validate the data being entered against another table that I would populate manually (Table 2) , and if the data being entered in Table 1 already exists in Table 2, generate a msg "This Entry isn't allowed), and not let the record be written.The key is that I don't want to do it via a primary key index restriction - I want to manually enter the Table 2 items to validate against.ASP.NET 2.0 VBWe are having a voting system, and if the users get crazy with votes for a particular person, I want to be able to enter that name into another table, and have the 1st table validate against the 2nd... sort of like "This user has had enough votes now !"
I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)
2) Now I want to check the selected items for a particular record in this list
3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load

View 1 RepliesI'm trying to validate that a GridView logated in one of the steps of the Wizard Control is populated by the user before the Next button is clicked. What I mean is that I need to block Next (or Prev) button until the user populates a gridview, once the gridview has at least one element then enable the (Next/Prev) buttons. How can I enable/disable Next/Prev buttons within a specific step?.

I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
<asp:DropDownList ID="ddlFilter" runat="server" >
<asp:PlaceHolder ID="ListItemPlaceholder" runat="server"/>
</asp:DropDownList>
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
<mytag:MyControl Mode="DropDown" runat="server">
<ListItemTemplate>
<asp:ListItem Text="C" Value="c"></asp:ListItem>
<asp:ListItem Text="E" Value="e"></asp:ListItem>
<asp:ListItem Text="B" Value="b"></asp:ListItem>
</ListItemTemplate>
</myTag:MyControl>
I know I can do this by dynamically adding the ListItems in the page code behind, but I'd like to avoid that if possible.
I am getting this error yet I know it to be untrue.This is the code:
ddlPartnerOrganisation.DataSource = agency.AgencyGetListOfEYDN();
string temp = ddlPartnerOrganisation.SelectedValue.ToString();
ddlPartnerOrganisation.DataValueField = "AgencyID"
;
ddlPartnerOrganisation.DataTextField = "AgencyName"
;
ddlPartnerOrganisation.DataBind();
How to validate dropdown list using javascript?
View 4 RepliesI wonder how to validate if a inserted item in a Combobox exists in a database during postback? If the item.text exists, a errormessage should notify the user that the item already exists in the database. If the item does not exists in the database a inserting should be done.
Should i use the customvalidator and create a servervalidationfunction that searches my databasetable for the item name?
Should i validate inside one of the two ComboBox control events, ItemInserting and ItemInserted?
After validating the existence i would like to validate if the inserting to the database was successfull.
Is it possible to select values from a List, where the items contain in a different list aswell?for example;

What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
Is there a simple way of putting all list items from a listbox into a textfield? I'm not interested in selecting individual items, I want all items in the box to appear. I'd like the items to appear in the textbox as x, y, z, or x y z. The seperator type / format isn't important as long as long as there is some sort of spacing between each item.

View 2 RepliesI have a list of objects that have values to them. Specifically one of these values if a boolean (isAbnormal) to determine whether or not the value itself is classified by our application logic as "Abnormal" or not.
I have composed a list of a mixture of abnormal/not abnormal items. I want and need to remove items from this list that aren't clsasified as being abnormal (in programming logic, isAbnormal will be false)
I have tried several ways and can think of some dirty/ugly ways to get it, but there has to be something better:

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?
View 5 RepliesI have a Drop Down List that has some items in it, I have a switch set up that will clear and repopulate the drop down list from a sql server db depending on which item is chosen. When the list is repopulated from a database table I want to use an if statement to do something based on which item is chosen. I've tried to use an if statement but no matter what I try, the code checks the if statement for the original items in the drop down list, not the items that repopulated the drop down list.

View 4 RepliesI format the items of two listboxes using padright with chr(160)'s to create the look of multicolumns. These display fine when the page is loaded by the browser. I then use javascript to move items between the two lists. The items move fine but instead of spaces between my "columns" I get blackdiamonds with white question marks. What do I need to do to retain the orignal chr(160) spaces in the list items once they are moved. Also, I should mention all items in both lists have the black diamonds.

just want to have a quick question about the value of dropdownlist listitem. I have a gridview which has its datakey value linked to a dropdownlist. In the dropdownlist I have many listitems. So I decided to combine some list items together. Originally, the values of the items are 1,2,3,4,5,6,7,8. But I want to have only 5 items by combining 5,6,7,8 into one listitem called "Others." So if the listitem "Others" is selected, the gridview will show all the records that have value 5 or 6 or 7 or 8. Is it possible? How can that be done?
I hope I made myself clear. Any question, I am happy to clarify.
