C# - Pass Model Values As Javascript Function Parameters From Inside Mvc Html Helper Such A Html.Radio?

Jul 20, 2010

I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:

function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}

Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.

<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>

The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.

<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>

Pass A Value To A Javascript Function?

Aug 12, 2009

I need to call a Javascript function to launch Word on the client's machine. I also need to execute a macro (named PopulateTemplate) to populate some terms on the Word document. I can get all of this to work so long as I pass a hard-coded string in the code as below:

[Code]....

The real need though is that the parameter 24 as above changes dynamically for each user. In the back-end code of the ASP.NET page I retrieve this from a database. I need to pass this parameter to the Word macro. I've tried populating a HiddenField on the form but I can't get the Javascript to pick it up. I have wrapped single quotes and double quotes around the Hidden field's ID but neither seem to work. I get no error message.

[Code]....

Pass ID From GridView Row To JavaScript Function?

Sep 3, 2010

The first commented line below is working with a hardcoded ApplicantId, and all I need is to make it work by passing the current ApplicantId column on the same gridrow.

I've tried for many days now, and something like the second commented line does not work for me.

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
DataKeyNames="ApplicantID" >
<Columns>
<asp:TemplateField HeaderText="Select">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<!-- works -->
<asp:HyperLinkField NavigateUrl="javascript:popUp(3)" Text="Select" Target="_parent"/>
<!-- doesn't work -->
<asp:HyperLinkField NavigateUrl='"javascript:popUp("<%# + DataBinder.Eval(GridView1.DataItem,"ApplicantId") %> + ")"' Text="View" />
</Columns>

How To Pass A List Of Values To Compare In A SQL Function In SQL Server 2008?

Feb 18, 2010

I have an SQL Function with the following SQL within:

SELECT StockID FROM (SELECT DISTINCT StockID,
ROW_NUMBER() OVER(ORDER BY DateAdded DESC) AS RowNum
FROM Stock
WHERE CategoryCode LIKE @CategoryID) AS Info
WHERE RowNum BETWEEN @startRowIndex AND (@startRowIndex + @maximumRows) - 1

I have a Parameter @CategoryID - however I need to take in a category ID such as "BA" and translated this to a list of Category IDs such as "IE","EG" etc so my WHERE clause looks like:

WHERE (CategoryCode LIKE 'IE' OR CategoryCode LIKE 'EG') AS Info

I have a Lookup Table which contains the "BA" code and then all the real category codes this means such as "IE" and "EG".How do I have the CategoryID expand to multiple "OR" statements in my SQL Function?

At the moment the query as shown can cope with one CategoryID such as "IE", this is done as I want a category page such as category.aspx where a parameter "BA" is passed such as category.aspx?category=BA and this page will list all items with the category codes "EG" and "IE".

The reason I need this is there is a "parent" category code which has multiple "children" category codes which are different to the parent code. I am using ASP.NET and .NET 3.5 on the front-end if this helps.

Pass Parameter As Text To JavaScript Function From Code Behind

Mar 23, 2010

Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window. All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.

JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;
}
.NET Code-Behind
Protected Sub RadGridOnlineRequests_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridOnlineRequests.ItemCommand
If e.CommandName = "ViewOnlineRequest" Then
' populates LabelScheduleDate among other controls values
ScriptManager.RegisterStartupScript( _
Me, Me.GetType(), "clientScript", "RefreshParent(" & LabelScheduleDate.Text & ");", True)
End If
End Sub

Pass Eval As Javascript Function Parameter In Gridview?

Jun 25, 2010

I have the following:

<EditItemTemplate>
<asp:Button ID="wrqst_need_ind_btn" runat="server" Text = "Create WR"
onClientClick="javascript:popUp('popup_createWR.aspx')"
CommandArgument='<%# Eval("dvc_nm") + "|" + Eval("data_orgtn_yr") %>'/>
</EditItemTemplate>

I want to pass in as two additional params the Eval("dvc_nm") and Eval("data_orgtn_yr") to the popup function.

UPDATE:

I tried by removing the single quotes from insode the <% %> tags. Which gave me this:

onClientClick='<%# "javascript:popUp(popup_createWR.aspx," + Eval("dvc_nm") + "," + Eval("data_orgtn_yr") + ")" %>'

which complied, but when I clicked the button I did not get a pop up, the page just posted back and reloaded and said errors on page, but no popup...

Pass An Anonymous Array Of Strings To A JavaScript Function?

Apr 5, 2010

I want to pass to an array of controls' IDs to a javascript script function so it will switch control's enable state.

For example, in C# it would be like this:

func(false, new[] { "Control1", "Control2", "Control3" });

In that function I want to find corresponding controls and disable/enable them. For one control I do this next way:

<script type="text/javascript" language="javascript">
function switchControls(value, arr) {
for (var n = 0; n < array.length; n++)
document.getElementById([n]).disabled = value;
}
</script>
<asp:CheckBox runat="server"
onclick="switchControls(this.checked,
[
'<%= Control1.ClientID %>',
'<%= Control2.ClientID %>'
])"
Text="Take?" />

How to implement this properly? Have I to use jQuery?

Web Forms :: Pass Variable As Html Control Through To Javascript Function

Jan 24, 2011

I have a function that gets the position of a control.

[Code]....

All the function needs is an htmlcontrol being fed to it as the parameter (elemRef). I can declare a variable in Javascript of the same content page but different function and pass the parameter successfullly getting returned values. For example, if I have the following function:

function (getPosition)
{ var txtBox1 = document.getElemendById('<%=txtBox1.ClientID %>');
getPos(txtBox1);
}

I will get the coordinates of the control txtBox1. But how can I accomplish this if I am calling this function from a javascript function or codebehind of the Master Page, or codebehind of the same content Page.

MVC :: Pass Parameter To Javascript Function From OnSuccess Event In Ajax.ActionLink?

Apr 27, 2009

When I use:

new AjaxOptions { UpdateTargetId = "VoteCount" + indx, OnSuccess = "AnimateVoteMessage" }

everything works fine...but I am trying to animate items in a list, with automatically assigned ID's. Since I want each of these to be addressable from my javascript, I believe I need to pass a parameter to my javascript. But when I use:

new AjaxOptions { UpdateTargetId = "VoteCount" + indx, OnSuccess = "AnimateVoteMessage(2)" }

I get an " Sys.ArgumentUndefinedException: Value cannot be undefined." exception. Well I get that when using the debug versions of MicrosoftMvcAjax.js. When using the compressed version I get a "Microsoft JScript runtime error: 'b' is null or not an object" So my question is, can I pass a parameter to my javascript function using the OnSuccess event for a ActionLink? Is this the right approach? How else am I going to have one javascript function have the ability to be run on 10 items (in my case the IDs of multiple DIVs) on my page?

How To Pass Values From Querystring To JavaScript

Nov 4, 2010

Now that i learned how to pass values to an SWF object via flashvars, how can i pass values from a querystring to javascript?

What do i mean? In the following example i hard-code the xml file to load in the SWF object.

<script type="text/javascript">
var so = new SWFObject("preview.swf", "", "100%", "100%", "9", "#ffffff");
so.addParam("allowFullScreen", "true");
so.addParam("scale", "noscale");
so.addParam("menu", "false");
so.addVariable("xmlPath", "xml/exampleData.xml");
so.write("flashcontent");
</script>

Since the Xml file is created dynamic, the xml should be loaded from the value of a query-string. (I guess).

Supposing my url is http://www.example.com/load.aspx?XmlFile=SomeData

How can i pass it to the javascript side? Like..

so.addVariable("xmlPath", "xml/<% SomeData %>.xml");

or whatever it needs to make it work.

UPDATE: Besides the above example, is there any way of creating the JavaScript, in server-side?

AJAX :: How To Pass 2 Variable Values Using JavaScript To A Web Service

Mar 7, 2010

How can I pass two variable values to a web service web method using JavaScript and a DynamicPopulateExtender?

Some background of my issue:

I have a fully working cascading drop down list accessing a database.

My parent Cascading Drop Down List is a list of countries and the child displays the relative regions i.e.: USA returns Iowa, Maryland, Oregon etc.

I also have a 3rd Drop Down List control that allows the user to select the language to display the region details i.e.: Selecting the language of Chinese will return a list of regions of the USA in Chinese (held in the database).

I now want to display the translated country name from the 3rd Drop Down List in a label on the page.
I cannot just use the text from the country drop down list as this text value remains in English. The translated value must be returned from the database.

So far, I have installed a DynamicPopulateExtender:

[Code]....

I then wrote a web method (in the Cascading Drop Down local Web Service) to return the translated country name. To do this I have had to hard code the countryID (10663) and the translationLanguageID (1331) asshown below:

[Code]....

This does return the translated country name, but the variables are hard coded!

My question is how do I pass the countryID and the translationLanguageID to the Web Method GetTranslatedCountryName() from the DynamicPopulateExtender? Or even if there is a better way to achieve my task?
