Yes.I understood your problem.I have given you an example.
Put dropdownlist and textbox in ItemTemplate,Bind Dropdownlist with data.
When you select items from dropdownlist,selected item value will be filled in textbox using that javascript.call javascript on onclick event of dropdownlist,you can not call selectedIndexChanged event because it will execute on server side while onclick event will execute on client side.
please don't forget to vote on the post that helped you.

Can you schedule a job from ASP.NET so that a background worker process can do that and send an email to the user?

currently i m using asp.net with c# (.net 2005, 2.0 framework).
here i m having 5 variables (Either int or string) say.... A,B,C,D,E. And the variables contains....
A=1;B=2;C=1;D=3;E=2;
Here, i need the output of the counts of the values...
i.e.,
count1=2 (since, 1 value occur twice in the A,B,C,D,E collection)
count2=2 (since, 2 value occur twice in the A,B,C,D,E collection)
count3=1 (since, 3 value occur only once in the A,B,C,D,E collection)
how to do this? - KARAN

Build a hashtable, which stores the number as a key, and the number of times it appears as the value. That would be flexible for any numbers that get added to your collection.

How can i find only the current page gridview rows?
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!
|
|
|
|
|
What do you mean?
You can set the gridview so paging is disabled.
There must be a current page tag you can use as well
|
|

i meant , in my first page , which contains 10 rows , how can i loop only for those ten rows .
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Hello. I am building an online control panel(back end) for a website, using asp.net - VB. One the things that I have to program, is the user to be able to upload files. But there is one issue. When the user's trying to upload a file that its size is bigger than the allowed size, he gets a "The connection was reset". My question is the following:
How do I face that?
* Do I have to write some code in order to control that? If yes, this code has to do with a HTTP Request or something, or is it something else?

Yes you need to have following element in Web.config
have added this in web.config ?
if not add it and check
<system.web> <httpRuntime executionTimeout="240" maxRequestLength="20480" /></system.web>
maxRequestLength: Specifies the limit for the input stream buffering threshold, in KB. This limit can be used to prevent denial of service attacks that are caused, for example, by users posting large files to the server. The default is 4096 (4 MB).
executionTimeout:
Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET.
This time-out applies only if the debug attribute in the compilation element is False. To help to prevent shutting down the application while you are debugging, do not set this time-out to a large value.
Note
In the .NET Framework versions 1.0 and 1.1, the default is 90.
The default is "00:01:50" (110 seconds).
Thanks and Regards

Hi,
There exists predefined limit on the size of file you can upload, however you can change the size.
By default the maximum size is 4MB. However you can change this value at two places web.config and/or machine.config.
<httpRuntime executionTimeout="90" <br />
maxRequestLength="4096"<br />
useFullyQualifiedRedirectUrl="false"<br />
minFreeThreads="8"<br />
minLocalRequestFreeThreads="4"<br />
appRequestQueueLimit="100"/>
Check for the above in the web.config/machine.config, if you dont find it, add it. Increase the value for maxRequestLength from 4096(4MB) to whatever you want. Remember when you increase maxRequestLength value, you should also change the value for executionTimeOut, this value specifies the number of seconds the upload is allowed by ASP.NET before it stops/shuts down.
Also note if you change the value in machine.config, we will have to reboot the system.
Location of machine.config = \System Root\Microsoft.NET\Framework\Version Number\CONFIG directory
In case you are using ASP.NET 2.0 instead of machine.config you can try out in web.config.comments files, which is present in
root\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG

To prevent DoS Attacks, ASP.NET breaks the Request when the size of the incoming stream is more than that configured for the application.

Hi,
I have small project that retrieve Data from Database and fill Datagrid On Page Load. I add Databound Columns for each Columns in the database, and set The AutoGenerateColumns=False, So My Data will be Displayed lik this
StudentName CourseName
John asp.net
Mary mcse
Komar MCSD
Komar A+
Komar 3D Studio
... I need to make Komar appears just one time, so the result Should be like this in the DataGrid
StudentName CourseName
Komar MCSD
A+
3D Studio
How Can I do This, some help Please.

add DISTINCT to your query for StudentName, this should then just select one unique student name.

A data grid is not the right choice for this. Use nested repeaters and build two collections, one of names, and one of courses for that name.
Or you could just handle the data bound event for a row, and erase the name if it's the same as the last name displayed.

This is a forum which is used to ask questions about coding errors you have encountered through creating an application.
We are not a code charity.
Do you want the gridview to be created at runtime or do you just need it to appear on page_load?

|
|
|

Ok, I want my gridview to be appeared on page_load with all the four columns.
