How do I indicate that an image button is disabled? Do I have to provide an alternate image, or is there some more sensible way?
It is quite important that the user knows when the button is enabled and when not, as it's sort of a guidance.
|
|
|
|
|
imagebutton.enabled = false
|
|
|
|
|
That only disabled the button, it doesn't change the image. Oops, you've just reminded me that I now have a nicely greyed out but still enabled button.
|
|
|
|
|
You could have two images buttons and then use them like following:
if (imagebutton.enabled == false)
{
Imagebutton1.visible = true
}
else
{
Imagebutton2.visible = true
}
|
|
|
|
|
That's unnecessarily complicated, as simple as it is. For now I just use two images, one green and one grey. I was curious as to there being a more elegant solution, but the only candidate there is a control derived from ImageButton that has two ImageUrl properties, and renders the appropriate one depending on its Enabled property.

Hi All,
I'm using two dropdownlists in page1 and depending upon dropdown1 selection I'm filling the dropdown2 using Ajax. After that I will add some more data to dropdown2 using page2.If I come to page 1 and select dropdown1 selection it is filling only the old data not the updated one.
It is filling data only once,2nd time if I select same option it is not going to the codebehind of my breakpoint..May i know the reason for this?
May i know where I have done wrong? How to resolve this now?
Thanks in Advance,

Hi,
I'm filling the dropdown from DB. Please find below the code:
function AnalystKeyChange()
{
var tlList = document.getElementById("ddldataset");
//Getting the selected country from country combo box.
var SelectedAnalyst =tlList.value;
// URL to get states for a given country
var requestUrl = AjaxServerPageName + "?Selectedtxt=" + SelectedAnalyst;
CreateXmlHttp();
// If browser supports XMLHTTPRequest object
if(XmlHttp)
{
//Setting the event handler for the response
XmlHttp.onreadystatechange = HandleResponse3;
//Initializes the request object with GET (METHOD of posting),
//Request URL and sets the request as asynchronous.
XmlHttp.open("GET", requestUrl, true);
//Sends the request to server
XmlHttp.send(null);
}
}
//Called when response comes back from server
function HandleResponse3()
{
// To make sure receiving response data from server is completed
if(XmlHttp.readyState == 4)
{
// To make sure valid response is received from the server, 200 means response received is OK
if(XmlHttp.status == 200)
{
analystListItems(XmlHttp.responseXML.documentElement);
}
else
{
alert("There was a problem retrieving data from the server." );
}
}
}
function analystListItems(alNode)
{
var analystList = document.getElementById("ddlAnalystReportTo");
//Clears the state combo box contents.
for (var count = analystList.options.length-1; count >-1; count--)
{
analystList.options[count] = null;
}
var analystNodes = alNode.getElementsByTagName('analyst');
var textValue;
var optionItem;
//Add new states list to the state combo box.
for (var count = 0; count < analystNodes.length; count++)
{
textValue = GetInnerText(analystNodes[count]);
optionItem = new Option( textValue, textValue, false, false);
analystList.options[analystList.length] = optionItem;
}
}
Please let me if I have to proivde any more information. Thanks for all your help.

So just to confirm you want to have a button at the end of your datagrid on the last page allowing the user to click and go to another page?
|
|
|
|
|
Yes
People Laugh on me Because i am Different but i Laugh on them
Because they all are same.
|
|
|
|
|
Not sure how to do this, you need to find a way of finding the last page or end row and then putting the button there
|
|
|
|
|
Ok thanks!
I will try it.

You can not pass Web Url in strPath,
You have to use local path.

Hi all,
My Application gives me an error of type "Cast from type 'DBNull' to type 'String' is not valid" when some value in the select statement is stored as "<null>" in the SQL Server 2000.
How could I return a "<null>" value from database, or is there a way to convert a value stored as "<null>" to any other value (example: zero or space)???
this is the sql statement in my web application:
Dim com As New SqlClient.SqlCommand
Dim ds As New DataSet
Dim da As New SqlClient.SqlDataAdapter("select X, Y, Z from hotels where X=" & Me.Xtxt.Text, con)
da.Fill(ds, "hot")
Note: This statement has no errors and works fine when no column in the database has a value "<NULL>".
Kind Regards

Yes there is ways of converting the data once it is brought back from the database using c# code.
Can you explain more?
|
|
|
|
|
I can 100% sure that the above doent produce any error. you may use some varriable to assing the returned value. There only you will get these error. Use Not .DBNull("ColumnName") function while assinging the value to a string
|
|
|
|
|
I have edited my question, could you please see my question again.
some of data in the SQL server 2000 has "<NULL>" value.
When I execute the above statements in the case there is "<NULL>" value in some field, then the above error happens: "Cast from type 'DBNull' to type 'String' is not valid"

You jus need an if statement saying
if(columns.value = null)
{
}
|
|
|
|
|
Could you please tell me how could I apply this to my statements:
Dim com As New SqlClient.SqlCommand
Dim ds As New DataSet
Dim da As New SqlClient.SqlDataAdapter("select X, Y, Z from hotels where X=" Me.Xtxt.Text, con)
da.Fill(ds, "hot")

My web page contains an image button enclosed within div tag and a list box. On page refresh, a wait message will also be displyed. But during refresh, the list box flickers, its size gets changed and part of wait message window goes behind the list box. Could anyone please help on this?
|
|
|
|
|
you could try setting the focus on the listbox on the page load or
try this: VisibleDuringInit = false for the listbox
