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.
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.
pass name of the textbox Control to javascript function
[Code]....
<script type="text/javascript" language="javascript"> var sum = 3; var textboxObj,ObjName; function validate(textboxObj,ObjName) { alert('Hello'); var arrayOfObjects = document.getElementsByName(ObjName); alert(arrayOfObjects.length); for (var i = 0; I < arrayOfObjects.length;i++) { alert('Inside for loop');............................
In a repeater control there is TextBox and corresponding to each TextBox there is Button control.On click of Button how can i pass TextBox's text that user has just entered ?
Below is the code:
[Code]....
Means on click of each Button how to pass there respective TextBox's data to a javascript function ?
I have a label "lbl1" that I am trying to locate in a content page from the Master page. I want to do it dynamically so I am trying to pass the name of the control (which in this case is lbl1) through as a parameter. I don't get an error, it just doesn't work. If I do an alert to see what the string "temp" looks like, it is correct, but iit seems as if Javascript ignores it. I believe it has something to do with the '<%= not being interpreted correctly by the browser I'm sure it is a simple solution, but I can't figure it out!
I have a gridview inside a user control bind to an object datasource. Now I want to bind the object datasource with a parameter from parent page. For this purpose I defined a public property in user control but how do I pass it with object datasource? I am calling from parent page like myusercontrol.parameter=querystring["id"]; How to bind object datasource with my parameter?
I have a page with some datasources in it. I am doing reenginering of the page itself and would like to split some parts of the page in several user controls. In my code I have an ObjectDataSource object with the following params
This piece of code automatically bind the hidden field "txtAlbumId" to the datasource. In my revision this datasource should be moved to a user control. What is the best way to handle a scenario like this?

I just like to know how to pass a parameter to the datasource of my dllItemCodeFooter and dllItemCodeEdit Drowndownlist which calls my getItemCodeList(decimal categoryID) method in the code behind. The value of the parameter will be seletectedValue of the first dropdownlist ddlCategoryFooter or ddlCategoryEdit).I know it could be done in code behind, but i prefer to bind my datasource in asp page. I want to achieve something like this DataSource='<%# getItemCodeList(ddlCategoryEdit.Seletected)%>'
I have designed a asp.net page which create graphs. I have written a class file (which contain a function to render the graph,a function for entering data named insertdata(string[] s,double[] d)) in App_code folder. I pass the value into the insertdata during page load_event. I saw a feature of googlechart.when you pass the value in url address bar it will create a graph according to that passed value. how can i pass the value into the insertdata() function through url address?
I have a problem to pass along public variables from C# code to the HTML code. I assign the variables in the Page_Load event and then pass along them to the Panel and Image control in the HTML code. Though I get this compileerror for the Width: "Cannot create an object of type "System.Web.UI.EbControls.Unit" from its string representation '<%setWidthImage%>' for the 'Width' property."
I don't know if this is even possible, but here goes: I have an ASP.NET page that contains an IFrame that calls an HTML page. Is it possible to pass a variable from the ASP.NET page to the HTML within the IFrame? More specifically, I'd like for the ASP.NET page to fill in one of the fields on the form within the HTML page.
for(var i=0; i<<%=Model.Mydatalist.Count%>;i++) { //then I need to pass i to Mydatalist like Model.Mydatalist[i] } //var myJSdata="<%Model.Mydatalist["&i&"]%>";
is not working.. as system see i (i's value) as a string, and will throw exception: cannot convert string to int.
Can someone explain to me the rules around what can and cannot be evaluated/inserted into markup using the <%# %> and <%= %> tags in asp.net?When I first discovered I could inject code-behind variables into mark-up using <%= I thought 'great'. Then I discovered that if such tags are present you can then not add to the controls collection of the page (that's a whole different question!). But <%# tags are ok.
Is there a way I can inject a code-behind variable or function evaluation into the page using <%# ?
the question says it all : i have a linkbutton to which i pass through CommandArgument a value and i need that value to be a javascript value.Edit : here is my linkbutton tag :
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?
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.
Generally I want to pass string result of some control to other control or htm tag like without using specific classes in my ASPX page, only my control and what asp gives:
but this doesnt work - href is not executed, server treats it literally <MyControls:MyContr Param="Tech"/> so I would like to know it is possible to do it like in JSP pages:
- pass <MyControls:MyContr Param="Tech"/> to some variable $myVariable - pass $myVariable to href like <a href="$myVariable" ?
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.

I have to pass a string value from the server side page (.aspx.cs) to a function in .JS page. I need to call the function in JS page from server side page along with string as a parameter.
