I need to make a server control for controlling layout on my page. For various reasons, I don't want to use a master template, and the easiest approach is to make a server control which exposes two child controls. The content on my webpage will be added to these two exposed child controls, which in turn will be rendered surrounding by the layout HTML I need. Everything works fine, except I have no design-time support for it. In other words, I can compile the code, but I have no intellisense on in, which is a major inconvience. I've tried adding the standard attributes to the exposed properties, but I keep getting the "Content is not allowed between the opening and closing tags..." error. Can anyone tell me which attributes I need to add to my control class or its properties in order to get Visual Studio 2005 intellisense to work with the TopContent and BottomContent properties? Thanks!

Nvm - got a solution on the ever-helpful http://forums.asp.net - changing the exposed control type to PlaceHolder instead of Control fixed it. Good enough solution.

Hi I have a page in which I have used another page in . In that <ifram> page there is a text box i-e named txtPO. How can i access that txtPO in that Page in which <iframe> page is used.

dear,
you can access it from javascript
document.frames['IFRAMEID'].document.getelementById('txtPO').value
where IFRAMEID is the id of your iframe

This isn't a complete solution but hopefully it will get you started....
This is a brief sample of a datagrid I created in v1.1 that had a "View Details" image button in the 1st column of the datagrid. This image was the same for each row with an image filepath that I hardcoded:
1) datagrid id="dgrdSample"
2) Add OnItemCommand="dgrdSample_ItemCommand" to the datagrid tag
3) First column was a "ButtonColumn":
<asp:ButtonColumn ButtonType="LinkButton" HeaderText="Sample" Text="<img src='../images/viewDetails.jpg' border='0'>" CommandName="select"></asp:ButtonColumn>
4) Add this to your codebehind:
protected void dgrdSample_ItemCommand(Object s, DataGridCommandEventArgs e)
{
//Add your code here for whatever you wish to happen
}
Hope this helps get you started.

Dear,
you can use the javascript setTimeOut function which will check the frames if loaded every specific time ( you set the specific time) below is an example
window.onload = function() {setTimeout(\"if(self.parent.frames['FRAME3'].document.readyState!='complete'){document.body.style.cursor = 'Wait';}else{document.body.style.cursor = 'default'}",100)}
Repeat this for each frame you have.
Happy Coding

Dear,
first create a function in javascript
function checkloaded(id1,id2,id3,id4)
{
setTimeout("if(self.parent.frames[id1].document.readyState!='complete' | self.parent.frames[id2].document.readyState!='complete'| self.parent.frames[id3].document.readyState!='complete' |self.parent.frames[id4].document.readyState!='complete'){document.body.style.cursor = 'Wait';}else{document.body.style.cursor = 'default'}",100)}
}
now onload in your tag, call this function and send your 4 frames id as parameters

what is the difference between codebehind and src in @page directive.
Thanks in advance,
Regards,
Prya
|
|

|

Dear,
if you are using Visual studio you have to use the codebehind directive because VS precompiles your application. if you use src, it means that you want to compile it straight away. if you using another developement suite u are required to use the src directive

How Can I access the contrl of one page in another page.
|
|
|
|
|
You can create a public property for that control on the page in question, but this is not a great way of accessing data (for a web application).
|
|
|
|
|
If you are using cross postback in 2.0, use the "PreviousPage" object and type cast it to the called page and access it controls.
