View 3 RepliesI'm trying to fix an issue with an application I'm supporting (I didn't write the code). The code takes an SSRS report and renders it in pdf format. Users are sporadically getting the error indicated in the title. There is no rhyme or reason to when the error is generated (a particular report will run one time and throw the error the next). The code is below.

I read that the default length limit is 4MB. None of the reports by themselves are even over 350K. I'm wondering if this could be caused by a caching issue. I'm not an expert, so I need some guidance as to how best to solve the problem. I also want to understand why the issue is happening. note that only 2 reports are shown in the snippet - there are about 30+ reports in the full sub. edit - I tried the proposed solution, but it didn't help (I also tried the Fiddler route, but did not see anything glaring). I thought it might be best to clarify. The reports will run fine for a while, but the execution time gradually gets slower and slower until the application eventually displays the error.
is it possible to set a maximum length in my field in gridview?
Below is my gridview sample that retrieve a formatted html in my database..All i want to achieve is to limit the maximum length of characters i.e "50" then automatically create a pagination for the succeeding characters..to be posted in the gridview
<div id="GridScroll" class="grid_scroll">

GridLines="None"
DataSourceID="SqlDataSource1" Height="308px" Width="1174px" ShowHeader="False">

View 1 RepliesI have written an asp upload script. It works ok for small files but anything over say 4 meg and it struggles. I keep getting the following error coming up:Maximum request length exceeded. Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.Exception Details: System.Web.HttpException: Maximum request length exceeded.So the above error comes up or it times out. Is there a way to modify the code so that it won't do this? I have included the code that I have written.

When uploading a file over 4mb I receive error: maximum request length exceeded. This is fine - I don't want users to upload files any larger. But, anyone know how to handle the error in a clean way? It appears I can't avoid it with an IF statement or Try/Catch block.
View 1 RepliesI am getting this error when I am trying to upload a video in my site. how to fix this?
View 3 RepliesIf I upload a file that is larger than the configs max request length I get a "Server Response Error: Unknown Server Error" alert popup. It asks if I want to see the response page and if I click "OK" an application error window pops up saying "Maximum request length exceeded." I found this already. [URL] I was unsuccessful at getting that to work.
I also found another SO question (I can't seem to find it now) that was similar. The difference was that the OP had asked how to redirect to an error page. I don't want to do that. The answer was to use a custom error redirect that gets setup in the web.config.
I simply want to absorb the error and do nothing, I'm using the OnClientUploadError event to handle the error via js. Basically, I just don't want this stupid popup message.
One odd thing is that I don't see the error when running the app locally, but I do see the error when I've got the app deployed out to our server. Note I should have mentioned that I know about the config value to set the max request length. Setting it to be very large won't work for this instance. Update So, I'm wondering if this could be something with the IIS settings of our server. It's odd that it doesn't happen locally. what I should be looking for? Most of what I find on the net suggests modifying the machine.config. However, as I said before, I don't simply want to up the allowed size. I am handling the error fine via js, I don't want this alert to show up under any circumstances. Update Well, it sounds like the IIS default limit is 30MB.
I used below code for my textbox that just allow enter AlphaNumeric characters
<script type="text/javascript">
var specialKeys = new Array();
specialKeys.push(8); //Backspace
specialKeys.push(9); //Tab
specialKeys.push(46); //Delete
specialKeys.push(36); //Home
specialKeys.push(35); //End

I am using DotNetNuke and I have posted this in their forum. But it is more appropriate here. I am trying to upload a 13 MB video file to my site ( a .flv file) using the file manager function under the host login. I understand that .NET limits the upload size to 4 MB for security reasons. In accordance with other posts here I added this code to my web.config file to allow bigger upload.
<httpRuntime maxRequestLength="51200" enable = "True"
I added it in the system.web section. Now, I still get this error:
"An error has occurred.DotNetNuke.Services.Exceptions.PageLoadException: Maximum request length exceeded. ---> System.Web.HttpException: Maximum request length exceeded. at System.Web.HttpRequest.GetEntireRawContent() at System.Web.HttpRequest.GetMultipartContent() at System.Web.HttpRequest.FillInFormCollection() at System.Web.HttpRequest.get_Form() at System.Web.HttpRequest.get_HasForm() at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) at System.Web.UI.Page.DeterminePostBackMode() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint,

When the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?

A very easy one hopefully - what expression can I use to validate an integer to ensure it is greater or equal to zero, but less than 2,147,483,647 (i.e. the maximum value of an integer)?
For example 0 =< x < 2,147,483,648
it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
View 1 RepliesI am trying to Upload data from Excel file. Transfer data from Excel file to XML file and passed it to Store procedure. And insert the record into database.I also set the timeout for command to zero. when i upload 1 to 500 rows its working fine and when I upload the 10000 rows than its takes time but upload all the users successfully at localhost. But when I upload the code to remote srever,than its only upload upto 300 or 400 rows.After uploading these users it will gives the error of Request Time Out . Even more if I tried to upload 50000 rows its give me the error of 'Maximum Length Exceeded'. Can anyone tell me what the maximum size of Excel sheet to upload the users. How I can get rid of the Request Time Out Issue. How I can Increase the server response time.

View 2 RepliesWe are using HttpRuntime.Cache API in an ASP.NET to cache data retrieved from a database.
For this particular application, our database queries feature a LOT of parameters, so our cache keys look something like this:
table=table1;param1=somevalue1;param2=somevalue2;param3=somevalue3;param4=somevalue4;param5=somevalue5;param6=somevalue6... etc...
we have so many parameters that the cache key is several hundred characters long. is there a limit to the length of these cache keys? Internally, it is using a dictionary, so theoretically the lookup time should be constant. However, I wonder if we have potential to run into some performance/memory problem.
I encounter "maximum length exceeded" error when I try to upload a document which is 9MB in size. I know that the issue will be solved if httpRuntime maxRequestLength and requestLengthDiskThreshold in web.config are increased but what I am looking for is how I can nicely handle the error and show the message to the user. I did try to use Application_Error event in global ascx but the event is not fired. The reason might be from Server.Transfer from DNN PageBase class's OnError method.
Specifications:
NET 3.5 SP1 (ASP.NET)
IIS 6
DotNetNuke 5.4.4(2)
I have a two-character field for US State. I add a RegularExpressionValidator control to validate the input using
ValidationExpression="[a-zA-Z]{2}"which works to validate the content when something's entered, but it doesn't catch if someone just leaves the textbox blank.
Is there any way to validate within the same regex to catch an empty textbox?
I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.
