Creating an instance of the webform class makes no sense. If the property you're after can exist outside of the form ever existing, then it should be factored out into a middle tier class. And if you're trying to access a value in a web form, you need to use the form instance that is generated when someone browses, creating a new instance creates new values, not the ones you're looking for.

It's a wrong coding approach.

AjaxPro Library and HTML problem .??? [modified]

devboycpp8-Sep-07 5:23

In my site I have used AjaxPro library to perform method invocation on the server side without postback.

My javascript code is something like this:

function my_func()<br />
{<br />
        var response = test.my_serverside_method(1,2,3);<br />
        if(response.error != null)<br />
        {<br />
            alert('error');<br />
        }<br />
        else<br />
        {<br />
            alert(response.value);<br />
        }<br />
}

In this function I have invoked the serverside method and used its result.What I want is to show a message somewhere in the page dynamically before the function my_func is invoked. But my problem is that when I try to make a change on the page for example setting the innerText property of a span tag , the change does not appear immediately .

This is the code:

SetMessage('Please wait ...');<br />
my_func();<br />
SetMessage('Data fetched !');

The function SetMessage sets the innerText property of a span tag to the argument passed.
It takes some seconds for the my_func function(its code shown) to get the data from the server. It is supposed when the above code runs first the message "Please wait ..." apears on the page and after some seconds the my_func function gives its results and then the message "Data fetched" appears. But in my case the first message is not shown at all and just the my_func is invoked and then the second message appears. How can I solve this problem ??? I hope you understand my problem . Please help me . Thanks.

Tables vs CSS for Page Index

Brady Kelly8-Sep-07 3:19

8-Sep-07 3:19

I've created a PagingIndex user control that takes a data source and allocates PageSize keys from the data source to each of a collection of PageEntry objects. Each PageEntry has a first and last property, e.g. "A - C", and I use a Repeater control with a Button as my item teplate. So, every Page entry has a button with, again, e.g "A - D" n it, if that range is <= PageSize, otherwise I subdivide, giving "Aa - As", followed by "At - Be" etc.

I currently use a one column table to contain the buttons, but was wondering, as I follow the school that asserts we should only use tables for tabular data, and not layout. What would my alternatives be for not using a table? An ItemTemplate with a <asp:button> followed by
suggests itself, but a table nicely disributed the button heights over the height of the containing div of the control. It;s not a big issue using a table, but I'm just curious as to other options.

I can't see what you mean. Use the "Ignore HTML" option when you are posting markup code.

Actually yes.
VS needs SQLServer runtime to work with it.
SQLServer 2005 Express included in VS 2005 DVD. install it from there.

weird situation with autopostback

RoyRose787-Sep-07 21:40

Hey all,

I have a DropDownList control in my page.
I set the AutoPostBack property to true and also created the SelectedIndexChanged event method.

Everytime I change the index it supposes to call the SelectedIndexChanged event but it only call it when index is not zero Mad | :mad:

With the use of debugger and breakpoint at this method I realized that when the dropDownList's SelectedIndex is not zero - the event is raized but when the index is zero it ignores the event

Please help Sigh | :sigh:

I have another comment..
The problem was with index 0
I realizes that when I set the item in index 1 to selected = true the event not fired to it!

<br />
<asp:DropDownList ID="_TableDropDownList" ... OnSelectedIndexChanged="_TableDropDownList_SelectedIndexChanged"><br />
            <asp:ListItem>cities</asp:ListItem><br />
            <asp:ListItem Selected="True">courses</asp:ListItem><br />
        </asp:DropDownList><br />

I set all items with Selected="False" but still when I choose the item in index zero it won't fire the event..

Youn can find one solution for that you can add some other listitem in place of listitem at 0 index as select or please select one or select one, or 0th index item you keep it nothing like
<asp:dropdownlist id="_TableDropDownList" ...="" onselectedindexchanged="_TableDropDownList_SelectedIndexChanged">
<asp:listitem>

<asp:listitem>cities
<asp:listitem courses<="" asp:listitem="">

I'm king of lost here...
this situation is very weird because the event is not fired when I select the first item in my drop down list..!

Let me tell you the exact problem:
I have a user control with a drop down list control.
This control is auto post back to server when index is changed.

When I select the second(or third, forth etc) item - the event method
_TableDropDownList_SelectedIndexChanged is being called.
When I select the first item this event isn't fired - so _TableDropDownList_SelectedIndexChanged is not being called!

I use breakpoints in this event method and also in page_load method and I can say that page_load is happend but _TableDropDownList_SelectedIndexChanged isn't. it just ignores it somehow when I select the first item...

Someone please Cry | :((

Dear All,

I have a gridview where first 2 columns are bound fields.
Next 3 columns have template fields with textboxes which are requiered to be filled by user.
i want if user does not provide any value, should be informed then and there through javascript.
I have written one which displays message but focus moves to next field.

I have given my code below.

Please help me.

Thanks;

-----------------------------

var gridViewCtlId = '<%=gridview1.ClientID%>';
var gridViewCtl = null;
var curSelRow = null;
var curRowIdx = -1;
function getGridViewControl()
{
if (null == gridViewCtl)
{
gridViewCtl = document.getElementById(gridViewCtlId);

}
}

function onGridViewRowSelected(rowIdx)
{
var selRow = getSelectedRow(rowIdx);
if (null != selRow)
{
curSelRow = selRow;
var cellValue = getCellValue(rowIdx, 0);
alert(cellValue);
}
}

function getSelectedRow(rowIdx)
{
return getGridRow(rowIdx);

Validate Textboxes values on RowDataBound Event of Gridview.
Try this code

OnRowDataBound Event:-

((TextBox)e.Row.FindControl("Textbox)).Attributes.Add("onblur","return Validate("+((TextBox)e.Row.FindControl("Textbox)).ClientID+");");

Javascript Function:-

Validate(txtID)<br />
{<br />
if(document.GetElementByID(txtID).value=="")<br />
{<br />
alert('Please Eneter Value.');return false;<br />
}<br />
else<br />
{<br />
return true;<br />
}<br />
}

Transfer session variables between asp.net and classic asp

I have a solution from the internet to acheive transferring of session variables. My application is failing with the following message:

The type of page you have requested is not served because it has been explicitly forbidden. The extension '.asp' may be incorrect.

Does anyone know what needs to be done to "read" ASP forms in an ASP.Net 2.0 web application?

Thank you,
Patrice

You can't. The best you can do is to look for solutions, which generally involve thngs like a windows service, which stores and passes values using the session Id, which will be the same.
