Is it possible to use a condition inside an actionlink ?I would like to do this :
[Code]....
This will be used for some column sorting and if the current sort was asc the next sort has to be desc. The code above is not valid while compiling.
I am trying to add an item selected class to an Html.ActionLink, I am very new to MVC so its all a bit confusing.So far i have each of my ActionLinks lookins like this
[Code]....
Can any one tell where i am going wrong because the links now fail to respond, basically it isn't checking the condition == Home and if it is then its failing because it doesn't get to the controller.
Just a fictional code, but why this won't work? (as the date variable is nullable)
DateTime? date = textBoxDate.Text != "" ? textBoxDate.Text : null;
The error is "There is no explicit conversion between System.DateTime and <null>
Global.asax route values
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional, filterDate = DateTime.Now.AddDays(-1), filterLevel = "INFO" } // Parameter defaults
);
Here's my actionlink
@Html.ActionLink(item.MachineName, "Machine", new { id = item.MachineName, filterLevel = "hello" }, null)
When the filterlevel is specified in the actionlink, it generates a url like this: [URL] Which is the same page as I am currently on. If I change the actionlink to use a property other than one that has a default value in the route table (yes, if I use filterDate it messes up too), it generates a link like this:..............
in my mvc2 application i have an action link like
[Code]....
docid is set to empty string because i want to clear ambient value of docid that is present in request context. i have gone through a lot of material on internet and even tried docid=String.Empty but it does not solve the problem and gives me url like /controller/action/id?docid=x. i also write a routeconstraint as suggested but it did not solve the problem either.clear those route values comming from request context with html.actionLink. i don't want to use html.routeLink
I have a gridview containing serial-numbers.
I would like to format the background each data-row that contains a duplicate serial-number value.
I'm planning to do this using a DataBound event handler.
So, in English:
Set background colour of THIS_ROW to red where the Serial_Number of THIS_ROW is the same as the Serial_Number of ANY_OTHER_ROW.
All rows with duplicate serial-numbers would be red.
I'm not sure how to write the code for this event.
The gridview is bound to a SQL datasource. Getting the dupes in SQL is easy:
SELECT Serial
FROM Table
GROUP BY Serial
HAVING (COUNT(Serial) > 1)
I need to pass javascript function as a parameter value to the ajax actionlink in asp.net mvc app. how can we achieve this?
View 1 RepliesThis might be confusing but ill try to explain the best as i can. I have a gridview that get the data from datatable. This is simulation my grid view.
key data
1 data1
2 data2
2. data2
2. data2
3. data3
3. data3
what i want is make some conditional statement, when value "key" is changed i want to add empty row. so its suppose to be looks like this as result.
key data
1 data1
EMPTY ROW
2 data2
2. data2
2. data2
EMPTY ROW
3. data3
3. data3
I'm working on a piece of code at the moment that allows the user to enter values into fields. Once the user clicks on the 'save' button I am checking those fields against certain conditions (essentially calling a bunch of stored procedures to assess the values). If any of these 'rules' are met, I need to generate a popup that informs the user that certain values need to be fixed before they can continue for some of the conditions, and for others just to inform them of what conditions may need their attention.
The main thing I need help with is, how do I generate a popup box in my codebehind if the conditions are met?
I use LINQ.But I can not add data twice "ZnizanaDnevnica.
How could you do one box:
tbl_dnevnice_obracun tbl_dnevnice_obracun = new tbl_dnevnice_obracun()
{ZnizanaDnevnica = ((totDiffHours> = 6 & & totDiffHours <8)? Convert.ToDecimal (dt.Rows [0] ['Znizana']. ToString ()): 0),((totDiffHours> = 12
& & totDiffHours <24)? Convert.ToDecimal (dt.Rows [0] ['Znizana']. ToString ()
I've got a weird problem: On a page, i've 2 updatepanels in conditional updatemode, with childrenastrigger set to true (default value).
A click on a IPostBackEventHandler control inside either the first or second updatepanel causes the 2 updatepanels to refresh.
I have an ASP.NET web app (with C#). In it I have a form with several fields and validators. For one of the validators I only need to validate when:
a certain textbox is empty and a certain record does not exist in the database (this is already handled).
I know I can't enable/disable the validator on page_load because something might be entered into that textbox. I also tried the following in the onclick event of the submit button but it didn't seem to work:
Validator1.Enabled = true;
Validator1.Validate();
I also tried Page.Validate() but that didn't work either...
I have a javascript src that i need to add to some of the pages in a site.
for example <script type="text/javascript" src="http:abcxyz.com/zzz"></script>
I want to add this conditionally on a .ascx page - if the Request.ServerVariables["SCRIPT_NAME"] ends with certain criteria.
The ascx language is vb, and there is no code behind.
Which of these will perform better if we assume that the IF block in #1 will be executed more and less in #2
foreach()
{
if
{
block here
}
}
or
foreach()
{
if !( )
continue
}
I've structured #2 to take the if conditional less often.
How do I properly write an if statement for t-sql in vb.net?
I have this code:
[Code]....
Is there any difference between below two statements
if (null != obj)
and
if (obj != null)
Edit: if both treated same which will be preferable?
I'm pretty new to ASP.Net / MVC 2. Can anyone explain how to use the Html.ActionLink thing? I understand that the first parameter is the displayed text, but for the second one, what is the action name?
View 1 RepliesI think this should be simple, but I can't find the option! How do I get a tooltip/alt for my ActionLink??
<%=Html.ActionLink("New", "List", "FormSummary", new {childId = Child.Id}, new {Class = "action add"})%>
I want to know how I could fix the following. I essentially have two almost identical SQL functions and want to combine them into one. The only difference between the two functions is the SQL Command text that is being used. Here is a brief idea of what I have unsuccessfully tried thus far:
[Code]....
I receive no compilation errors, but the exception is thrown and table is not filled. I have a feeling that I am overlooking something obvious.
I found this thread while trying to resolve my issue unfortunately this I can't seem to figure out the problem since I already have everything the way it should be.
I've got 3 updatepanels that each call a function on a .js file setup like this:
<asp:UpdatePanel ID="upPnlGeneralinfo" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
<ContentTemplate>
<script type="text/javascript">
Sys.Application.add_load(BindPageLoad);
</script>
Each have a different ID of course. Whenever a control calls a postback within the update panel it works, however in the js file I added a console.log("running the js file") and I can see that it's being called three times meaning it's all three updatepanels are being refreshed instead of just the one.
All the triggers are inside each of the respective updatepanels so I shouldn't need to add any triggers (I did just to make sure and it makes no difference). Shouldn't the UpdateMode=Conditional resolve this?
Also worthy to mention, none of my code behind ever calls any updatepanel.update(). I tried adding that for each control to their respective panels and that also made no difference.
I'm binding my DataRepeater control to a table that has many columns. I'd like to only display a subset of those, depending on what is populated.How/where should I do my contitional tests within a dataRepeater? This is the code within my itemtemplate:
View 1 RepliesJust to get it work, I got a controller action that make use of a switch statement to decide which partial view to render, based on one of the members of the model passed in. (Written by someone else for what it matter...I'm just cleaning up)
The viewmodel is overcomplicated, but that's not my decision right now and just have to live with it.
All partial's get rendered passing the same viewmodel, just a different partial get called.

I have this itemtemplate for a gridview column that is pulling data from a SQL database. My Question is how would I perform a check to see if my field ActivityFile has a value (which means a file is in the db) and then display the LinkButton at which point I generate code to download the file (already done and works).
<ItemTemplate>
<asp:LinkButton ID="DownloadFileBtn" runat="server" visible="false">Download File</asp:LinkButton>
<br />
<a href="<%# Eval("ActivityLink") %>"><asp:Label ID="Label4" runat="server" Text='<%# Bind("ActivityLink") %>'></asp:Label></a>
</ItemTemplate>
Is it possible to extend the RequiredAttribute class in a way to have it validate a condition against another property in the model? For example, in my hypothetical code.
[Code]....
The DriversLicenseProperty is to be required in the model if HasLicense is true. Is this possible? Is there an example somewhere?
We're trying to get a conditional attribute to work, case in point, there's a boolean (checkbox) that if checked, its related text is required. So, ideally we'd have something like ...
public bool Provision { get; set; }
[ConditionalRequirement(IsNeededWhenTrue = Provision)]
public string ProvisionText { get; set; }
Is this even possible?
Alternate idea (not as elegant?)
public bool Provision2 { get; set; }
[PropertyRequired(RequiredBooleanPropertyName = "Provision2")]
public string Provision2Text { get; set; }
I'd hate to use the magic string method .
