Hi,
I downloaded trial version of Webdropdown version:11.2.20112.1019 and started using that in my application to see whether it functions properly. If it works well, I can go ahead to buy paid license for this control.
It has been around 45 days I downloaded the control and now I am able to see one issue suddenly.
When I use $find("webdropdowninstance"), it retrieves NULL.
Is it because the trial version might have expired or there is some other issue. Please let me know.
Hi, Sunil Mehta.
You can check this forum post, I think it will help you. If you have some other questions don't hesitate to ask them.
Best regards,
Nikolay
Hi Nikolay,
I have tried using ClientIDMode="Static" like this:
<ig:WebDropDown ID="dropdown" runat="server" ClientIDMode="Static">
</ig:WebDropDown>
After this, I tried using $find("dropdown") and also #find("<%=this.dropdown.clientID%>") but both are returing NULL value and not the object. What may be the issue?
Note: I am using ClientIDMode as "AutoID" in web.config file and I am not looking for a solution to make ClientIDMode changes in web.config.
I am getting some other issues with the dropdown. Here is the description:
I am using "onchange" event on the webdropdown to call a javascript function. But that function is not getting called.
aspx file:
<ig:WebDropDown ID="cmbSrcGrp" runat="server" cssclass="igdd_Control" Height="12px" Width="415px" tabIndex="4" onchange="SgrpTest();" EnableCustomValues="False" ForeColor="Blue"></ig:WebDropDown>
javascript file:
function SgrpTest()
{
alert('Hello');
}
Can you please help me with this issue?
Thanks,
Sunil Mehta.
You should use client-side event SelectionChanging of the WebDropDown and use it instead of onchange. This event happens just before the value is changed on the server and if you are making some validation you will be able to cancel the call to the server if this is your goal:
<script type="text/javascript">
function wdd_SelectionChanging() {
alert("Hello");
script>
<ig:WebDropDown ID="wdd" runat="server">
<ClientEvents SelectionChanging="wdd_SelectionChanging"/>
ig:WebDropDown>
Thanks, Nikolay
Thanks Nikolay for the reply. Do you have any reference document for client side events. I would like to know about "ValueChanged" and "ValueChanging" as well.
Moreover, can you tell me the code-snippet to focus on a webdropdown. In my application, I was using the below line to focus on the old combobox:
document.all.combobox.popup.textfield.focus();
One more thing. I chose "View Source" after implementing the webdropdown in debugging mode and i am able to see the below details:
Here you can find the list of all WebDropDown client-side events. All of them accept 2 parameters: sender, which is reference to the WebDropDown client-side object; args - specific arguments for all the events. In this list you can find the different types of event arguments. The other option is if you have IntelliSence in your Visual Studio, it will show you all the possible values for the client-side events and you don't need the help.
In the second of your posts, the items that are in bold, I suppose are the values of any drop down item. So you can take them using the following code:
function wdd_Initialize(sender, args) {
// use this line of code if you are inside WDD client-side event handler.
var wddObject = sender;
// use this line of code if you are referencing the WDD from exteranl function.
// var wddObject = $find("<%=wdd.ClientID %>");
// get the value of the first item - "0901|0"
value0 = wddObject.get_items().getItem(0).get_value();
// get the text of the first item "ADR"
text0 = wddObject.get_items().getItem(0).get_text();
I have also one other suggestions for you. When you want to understand what methods are supported by the client-side WDD object, just put a breakpoint in you browser at the wddObject variable. Then, at runtime, you can inspect all the properties and methods of the control and find the most appropriate for you. This is what I'm doing. So finally if you want to focus on an element you need again to use the JavaScript method focus(). You just need to know which element you want to focus and to find it using the WDD client API. If it's the whole drop down I suppose it will be fine to use wddObject.focus(). But you need to investigate and check this.
Best regards, Nikolay
If it's not a problem for you, please create different forum thread for this issue. It's because the last problem is different from the title and idea of the current forum thread and it such cases is better to separate them.
Thank you
Is there a way to set the current display text and value of a webdropdown in the server-side(code behind vb file)?
