Hello Kinnu,
Thankyou for your reply.
I did try giving it a default value 'F' with 7 without quotes, I even tried default value false and NULL but it didn't work and SQL database is giving me an error when I type the default value as: Error validating the default value for column 'currentdriver'. It does not give me this error when I enter default value as NULL or 0 but my program is still not working and giving me the same conversion (DBNULL to Boolean) error.
Thanks once again. Please let me know if you have any other tips or suggestions.
Aartee.

Since this is a bit column you need the default value to be 0 which is false and then you would avoid this. Also if you dont want a default value, create a Protected Function in the code behind and pass the value from the Datagrid DB value and accept it as an Object, check for DBNull and if it is return a 0/False whatever works.

You can handle onkeyup event of textbox and populate listbox with neccessary items in it
function getKeyCode (e_) {
return parseInt(e_ ? e_.which : window.event.keyCode);
}
function srcEl(e_) {
if (window.event)
return window.event.srcElement;
else
return (e_ ? e_.target : null);
}
function onKeyUp(e) {
var textbox = srcEl(e),
keyCode = getKeyCode(e);
var text = textbox.value;
....
fill list box based on "text" string
....
}
textbox.onkeyup = onKeyUp;

Hi Folks,,
I have a web page with multiple buttons on it...Each button is responsible for retriving and presenting information on this web page...
I want to implement caching on this web page where I can vary the page depending upon which button caused the postback...
Can anyone suggest how can I achieve this...

Hi there:
I'm not sure what you need about caching based on e.CommandName...
For caching...just simply load data and put it into cache...
<< >>

|

|
|
I dont wanna cache the entire data set...I just wanna vary the cache based on the commandName property of all my button controls..
Thanks

So what is your problem when do caching based on that commandName...?I think, when a button is cliecked...you just check if the data is already cached or not...if not, load from DB and cache it...if already, just read from cache...is that ok?
<< >>
|
|
|
|
|
Actually I am using Output caching ..not data caching..
<%@ OutputCache Duration="120" VaryByParam=
I wanna cache different versions of the page depending on the commandname argument...

Hello all,
I have been working on this project for quite some time now and to be honest i cant stand it anymore! I have a simple request, i want to get a parameter, taken from a querysting and pass it to a crystal report.
I have setup the crystal report viewer on my default.aspx page and by setting the default value of the parameter, i am able to view the crystal report. Here is the follwing code that i use
---------------------------------------------------------------------------------
<CR:CrystalReportViewer ID="rptViewer" Runat="server" AutoDataBind="True"
Height="947px" ReportSourceID="CrystalReportSource1" Width="845px" DisplayGroupTree="False" EnableDatabaseLogonPrompt="True" HasRefreshButton="True" />
<CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
<Report FileName="SS_Server.rpt">
<Parameters>
<CR:Parameter ConvertEmptyStringToNull="False" DefaultValue="45"
Name="SERVER_ID" ReportName="" />
</Parameters>
</Report>
</CR:CrystalReportSource>
------------------------------------------------------------------------------------
This code works fine, however i want to have the parameter SERVER_ID to be taken from a querystring sent to this page! Si in my innocence i thought, instead of having the defaultvalue="45" can i use DefaultValue=" <% response.write request.querystring('server_id') %>" but this doesnt work.
I have read somewhere that like a control parameter one can code a querystring parameter! Does anyone know how to do this??
Im sure someone can help me, the idea behinf this is so simple, but im only new to Asp and am not sure where im goin wrong.
If anyone can help it would be greatly appreciated!

Do you get any runtime exception ??
Make sure the parameter type on the report and your program match...
Also try using DefaultValue=" <% request.querystring('server_id').tostring() %>"
Let me know...

Jo, thanks for your reply and suggestions
1. no i dont get any runtime exception
2. yes the parameters match
3. i tried ur method but it acts the same as mine, it simply prompts for the parameter, server_id
i was reading on MSDN site that one can use a querystringparameter;
http://msdn2.microsoft.com/en-us/library/ms227827(VS.80).aspx[^]
However i cannot find any example that use this and cannot get the querystringparameter tag to work!
Could it be that the crystalreportsource control does not allow this segment of asp code??
Could it be somethin wrong with my web.config file or something im not including in the default.aspx.vb page????
Any help would be great,
Thanks again

Is this report being set off by a click of a button...
Just a thought...Try saving this query string variable in viewstate in your page_load method...
ViewState("x")=QueryString("serverid").tostring()
Then use ViewState as a parameter...
If you have prepared crystal document object use
crDcoument.Parameters.Add(x,y) method to associate the parameter value with the report..
x=name of the parameter in crystal report
y=value of the parameter..in ur case its ViewState("x").tostring()
Let me know

No, i click a hyperlink in a page which directs to default.aspx like this /default.aspx?Server_id=45 then in default.aspx i have a request.querystring('server_id') statement, this all works, and i can read the value 45, but i cant insert the request statement into the crystalreportsource control!
Im not great with VB, and so dont really understand what you mean by ur last post Jo, but am i wrong in my method, surely it should be so simple!
Could it be something got to do with the crystalreportsource control. like it doesnt accept asp code in the middle of it??
I am also reviewing this example, and i cant pass a parameter into that either!!!

Hi Kavi:
The solution is that you should do this by dividing big task into small tasks...first you know how to design GUI? Know how to read data from DB?....And ask the specific questions here
<< >>

Divide the problem in three parts GUI,Business and database layer
crate one after another First try yourself any problem arrives then ask
