This is my first time here.
I have almost no experience in ASP bu tI need to develop a small site linked to an access database in order to load data.
So, in my site I've got two combobox or if you prefer List/Menu controls.
It's working ok, I mean, if I choose an option in each combox it filter.
What I need to to have an option in each combobox to not filter, such like an option saying ALL, so if I choose the option ALL in one combobox it would show all records.
I hope I was clear.
Please help.
Thanks.

If you are using ASP 3.0, you simply add a new item:
<select name="mycombo">
<option value="0">All</option>
...
</select>
Check for the item 0 and dont act on it.
If you are usng .NET
<asp:DropDownList id="mycombo" runat="server">
<asp:ListItem value="0" Text="All" />
...
</asp:DropDownlist>
When you choose All then remove the filter criteria and show all records.
First of all add the option All to your combo box at a specified index. When the combo values is changed check for that index and if it is the index of 'All' then remove the filter criteria applied and show full records.

I am using react-dual-listbox. Here I am able to select the columns and deselect and use the selected values. But, I want to access the selected option in selected items on click of that particular item.
Ex: if 2 options are selected. If i click on second one, It should give me the value and index of the selected option. I saw something to use selectedRef for that purpose, But I am new to React.
Could anyone please help me out.
<DualListBox
canFilter
preserveSelectOrder
options={this.state.availableColumns}
selected={selectedColumns}
onClick={this.selectedRef}
onChange={this.onColumnSelected}
/>
We are able to create ComboBox and populating data too. But we need to highlighting already saved values. Can you please suggest code for this.
Our requirement is if Combobox has 1,2,3. If I select 2 and save. We need to set the combo box value 2 in such way that when we open the Combobox need to display this 2 as highlight value along with 1,2,3 values.
Simply same as select box option selection.
I would generally recommend avoiding ComboBox altogether.
Assuming this isn't an option you will need to define a renderer and disable the OS specific 2 render mode using a theme constant:
otherPopupRendererBool=false
We are having a cascading LOV -> Deaprtment, class(inputComboBoxWithLOV). Class LOV is filtered with selected value of Department. When I follow the below steps:
select a department
click on the down arrow to show filtered results, I see filtered classes with the selected department. Select a class and tab out.
clear the class field, again click on the down arrow to show filtered results.(P.S : Department field is not touched) But the class field is not showing filtered results. But when I clicked on More... to display the Search and select popup, I could see the filtered results.
Only the the combobox dropdown values were unfiltered.
On Debugging, found that the viewCriteria which was applied to filter using Department is missing. The entire Where clause is missing.
This is occurring after our latest migration to 12.1.3, earlier we were using jdeveloper 11g and never faced this issue.
Any pointers about this issue will be highly appreciated.
The LOV UI hints "Filter Combo Box Using" option was unchecked, when I checked it and tried I was able to see filtered results in the dropdown.
However I did not understand why it was not picking values from existing view criteria from the view object definition related to the LOV's view accessor and why should I explicitly check this option.
This sounds like a 12.1.3 ADF BUG. You should fill in a Service Request with Oracle about it.
If you don't have a SR account, I will be happy to fill one in your behalf, if you can provide a sample workspace running on HR schema where we can reproduce the problem.
I'm creating an web site MSI using WiX. I have a custom action (written in C#) that fills a combo box with the descriptions of the web sites in IIS so the user can select an existing web site to install to.
Works fine - apart from the fact that there's no item selected when the dialog page is first shown. I'd like the first site in the list to be selected by default.
Any idea how I might do this? None of the "obvious" (to me) things seem to work.
I'm using the latest version of WiX.
Each row has a value and the control has a property. The property will have the value of the selected row. There is no concept of control.value or control.selecteditem.value in this language.
There is actually a possibility to preselect exact value for a combobox - just set the property, which is connected to the combobox, in your Custom Action's code to the desired value and it will get preselected in the UI.
For example, if you have a combobox
<Control Id="WebSiteCombobox" Type="ComboBox" Property="IIS_WEBSITE_ID" Width="320" Height="16" X="20" Y="80" ComboList="yes" Sorted="yes"/>
then, in you custom action's c# code:
foreach (Site site in iisSites)
{
//code to fill the combobox
}
session["IIS_WEBSITE_ID"] = iisSites.First().Id.ToString(); //Or to any other value you want to be preselected
I have been searching for a while now, and have not been able to find a load-on-demand combo box that populates itself depending on what is typed in the combo-box.
I also have a requirement that an item in the list must be selected (i.e.: free text can be entered but not "selected" - only a "search result" can be selected from the list in the combo box.
The scenario is as follows : there is a text box/combo box where someone enter the first 2 or 3 characters, a web service is called which queries a database and then populates the combo box.
Are there any controls or code example that anyone knows of? Or alternatively another way to implement this?
Here is a link to an asp.net control that has this functionality:
http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
use the event "textchanged" to dynamicly add/remove items :)
updated :
why not bind the results to observable collection and databind that to the combo box , so on chnage > query database > bind items to the collection , .net automatilcy updates the items , this might work :)
Telerik combobox with autocomplete will be what you are looking for.
