Web Forms :: Conditional Skipping Of Validator Controls?
Mar 4, 2010
I have a query regarding asp.net validators. I want to conditionally skip asp.net validators and allow/disallow form submission based on a checkbox for skipping validations. I tried a few things but I am facing some problems. Please see the code snippets below to get an idea of the requirement.
I'm having a problem with a formview i've created. The formview itself uses a costum template to perform updates to the database. Its a form to edit Car details. One of the details is the brand. I use a dropdownlist control to let them select the name of a brand thats in our database, this passes an ID to BLL's update so the car gets updated with a brandID. My update query works perfectly when i try it directly on the database, however, when i use the formview it updates everything except the brand.
When I debug and watch the NewValues object he passes, it does contain the new value for the brandID.
btw, brand is 'merk' in dutch, so brandID is called 'MerkID', and the brandname is called 'Naam'

I have a validator on a textbox that validates against a list to ensure that the user doesn't input the same name. When testing it, if I type in the same name including the same case structure, it returns an error. If I change one letter to a different case, it doesn't return an error but rather my SQL server returns a duplicate error. How do I change the server-side validator so that it picks up duplicate names regardless of case?
My ASP.NET application is using an assembly without strong name. When I run it in IE, it shows an error saying: Could not load file or assemlby 'xxxxx.' or one of its dependencies. Strong name signatuer could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)"I use sn.exe -Vr xxxx to register that assembly to skip the strong name verification, but still it shows that error. What could be causing this problem, and what can I do next to fix it?
I have a problem with Visual Studio Debugging. I use some Skin for my Web Application, e when I debug it, the debug controls stops on the skin. I press F10 multiple times, but I've never reached the end of the skin file in this way. It's a problem for me, since some times I don't know where the control goes after the skin. And pressing F5, I lose the control on the debug flow. Does someone know how to avoid the Skin debug (o better, the debug of certain file extensions) in Visual Studio 2008?
I need to add a check for a checkbox column in the grid. Something like:If CDate(e.Row.Cells(6).Text) < Date.Now and 'checkbox is checked' Then make another colorHow do I check for the value of the checkbox?
I have a gridview on my aspx page. I know we can format gridview row in rowdatabound() of gridview. But my problem is bit different.
In my gridview, i have a column customer code, a single code can repeat more than once successively. I want for one customer code, row color should be blue and as soon as code changes colour should be yellow for that code. Similarly when code changes again color should be blue again.
In this way color of my gridview rows should be blue and yellow alternately based on my customer code.I have arranged customer code in order by using sql order by clause.
I am using a column named "bk_End_Date" in my gridview.I want to change the row color based on a condition.i.e. if the date value is within one week of today's date (upcomming days only), it's color should be red.I tried following method in RowDataBound Event of C#
When it comes to field validation, when I use a Compare Validator to make sure a date is a date or a numeric field has a number, I must also use a Required Field Validator to make sure there is something actually enetered. In other words, the Compare Validator allows a blank value even though a blank is not a date or number or whatever.
Is using both a Required Field Validator and a Compare Validator the way to do this or is there some way to make the Compare Validator also require input of some kind?
I have a sql-bound formview with three DDL's bound to individual SQL datasources. In edit mode, I want to set the selected value to the formview's value, and this works:
But it only works when there's a match between what's in the formview's DS and the DDL's DS.
Unfortunately, there may be instances where the the formview's DS may return a null value or a value different from the DDL's datasource...and when that happens I receive a compilation error like:
'ddl2' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
What do I need to do to trap that condition before attempting to set the selected value? Do I need to set the selected value of the DDL in formview's dataBinding or dataBound event, by looping through the DDL and checking for a match first?
In my repeater I am attempting to set the label format based on a value from my datasource. The following line from my repeater is straightforward enough but now how would I modify it if I wanted the "C2" statement in the ToString to pull from a field in my datasource named "MyFormat" which would contain either the C2 or N0 value? Basically switching the formatting for that label between currency and a double?
I use ObjectDataSource and FormView for Editing of table data. Fields of table are to be edited by a few users.I use common page using ODS and FV (EditItemTemplate with a table) and want to succeed above purpose by allowing relevant fields to respective users.By searching through Google, I use table row's visible property like below
I want to have a listview with conditional formatting on its edit and delete button.So, in nutshell, I want to check if the writer of post is equal to session("memberid"), then the edit and delete button will be appeared, else, it will show hidden.
[Code]....
roughly, i want and plan it to be sort of like that (as i found it at [URL]But I do not have any idea on how to make it whatsoever.So, if you guys have any idea (same as method above or different method), please show me the way.I have seen another forum, but I don't get it.
I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.
My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processedafter the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.
Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.
