I'm attempting to validate the width of an image to make sure that it is at least 130px wide before uploading it to the server
Below is how I tried to accomplish this, however, I was still able to upload images that were less than 130px wide without drawing the error as intended
I found this article [URL] on how to create a customvalidator for the checkboxlist. Followed all the way thru, but when i load my page i get the following error, how can it exist in 2 places? How can i resolve this to use the validation on the page?
Compiler Error Message: CS0433: The type 'CustomValidators.RequiredFieldValidatorForCheckBoxLists' exists in both 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot294f506e54827e67assemblydl3b4b5a368e15533_8dcfca01RequiredFieldValidatorForCheckBoxLists.DLL'and 'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files oot294f506e54827e67App_Code.5yh9snf-.dll'
The lack of an EditorFor file in asp.net mvc 3 seems like such a glaring omission I wonder: Is there some way that mvc handles file uploads that is just not publicized that well? As near as I can tell there is no built in way to handle file uploads.I'm just curious if the file upload capability is in fact there and I'm just missing it, or if it does not exist at all.
I have two CustomValidators, both of which function in the same way (call a query and check if a particular value is available in the DB), the only difference is the query itself.
Rather than writing the same function definition in the code-behind, I would like to find a way to execute a particular query depending on which CustomValidator called the function (I guess using the CustomValidator's ID) so if I have the follwing:
[Code]....
How can I check in the code behind , which validator called the function "Check"??
How to get data (read file) chosen in FileUpload control without FileUpload.SaveAs Method on the server? Is it possible write it at once to some object?
I am clicking one linkbutton to check the validators clientside in the panels. This works well in IE, but not in Firefox. When I click the button, it does not even hit the validateLength function
Sample code below. Either I am doing something wrong or missing something in 4.0.
1: The function CheckText fires upon button click in IE but not in FF. 2: The function CheckText fires upon button click in IE /FF when the site runs under 2.0 or 3.5.
How can I set an error message in a CustomValidator and show this with the ValidationSummary after the submit with JavaScript.Thus, I want to trigger the Customvalidator with Javascript.
I try to use CustomValidator ClientValidationFunction. The issue I have is CallBack using Asynchronous call which make it difficult to detect when the call is complete.
var callbackresult; function ValidateSomething(src, args) { MyCallBackMethod(param); How shall I check when the call back is complete??? Any workaround? if(callbackresult == 'true') args.IsValid = true; else args.IsValid = false; }
function CallBackRef(result, context) { callbackresult = result; }
I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
I'm trying to compare two dates to make sure one is not greater than the other using a customvalidator and validatorcallout. However, I can't seem to get it to work and I've tried many examples but I can't seem to get what I want to work
i have written a dynamic formular designer that generates all its form elements from a database at runtime. The controls of the forms are entered into a table.
The HTML Table is the value that i return to the caller of my method so the caller can display the table insidehis own page.
I try to use ClientSideValidation to check the inputs of the form fields. So i generate a CustomValidator and try to add itto my table. But then there are some client side funtions missing, e.g. Page_ClientValidate().
When I add a static CustomValidator to the aspx Page (of the caller) the functions are existing. But i don't want to place a static CustomValidator on each ASPX Page that uses my Formulardesigner...
But how can i get the javascript functions added to the page at runtime? I added my javascript code for clientvalidation functions withClientScriptManager and RegisterStartupScript but how can i add the javascript functions for the CustomValidator add runtime?
i have 2 texztboxes for password function. Now i want to use the customvalidator to compare the 2 textboxes instead of the comparevalidator. I used a cs code like this bloew, but it doesnt work.
I have a CheckBoxList generated from the code behind file that I want to validate with a CustomValidator.However, I don't succeed in stating the C# function that it has to use, and I can't seem to bind it to the CheckBoxList control.
[Code]....
and then something like:WorkCheckboxValidator.ControlToValidate = WorkScheduleCheckboxList.ToString();
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
