have two user controls on one aspx page. UC1 has a grid which contains a link button column which user clicks. Based on the value of clicked cell, I need to show some data into UC2.How do I pass data from UC1 to UC2? How do I invoke a function of UC2 from UC1?
View 2 Replies I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
I want to use the Control of ASP.NET (User wizard Control) to create user, but it only provide its default field like: -username, password, securityQuestion.All I want is the addtional information like Address, Company Name, Telephone number. And I know a solution by building it in 2 step, first the default username, passworld and the next step is the additional information. BUT i don't want to do like that.
View 7 RepliesI'm dynamically loading a user control from a for loop against a objects collection, eg.
[code]....
I want to pass the following collection into the user control: oPerson.Address[i].listHistory (listHistory is a List of objects which I want to manipulate inside the usercontrol)
How can I pass this into the usercontrol so i can do this
Again, I am wondering why there is no one asking this kind of question. And may be my idea is wrong. Let's see the code:
<uc1:drilldown ID="drilldown1" runat="server" sType="F.W" rID='<%=request.querystring("r") %>' />
After it passed into my property in user control, the value is <%=request.querystring("r") %>
It is absolutely not reading my function!!
I have a user control that contains a reportviewer control.And I want to send an array of reportparameter to my user control.But I can't figure out how to do.I'm getting "Object reference not set to an instance of an object. ".My param_reportParam variable is null in usercontrol.My user control's parameter is like that ;
[Browsable(false)]
public ReportParameter[] param_reportParam [code]....
And a simple page that uses user control to show server reports is like that ;

parameters[0] = new ReportParameter("imza", imzalayacaklar);
parameters[1] = new ReportParameter("Sayi_Son_Eki", "984");

I have a aspx page and there is a web user control that must load dynamically with the data related to the aspx page....
ok so I want to use a querystring and pass it to the web user control.....how do I do this?
then also how do I pass a querystring from a web user control back to a aspx page?
This is a question I always had...and therefore never actually started to use the web user control

I have a page that contains a few user controls which all use an id in a querystring. I want to change this so that the page can send the id to the user control and can call a function on the user control.
Also is it possible for the user control to get the id from the page or a control on the page as its parent?
I have one ASP.Net web page dynamically loading any one of about twenty User Controls at a given time. Since each user control is somewhat different, I've implemented the following extension to me pass a variable number of parameters to custom user control constructors: [URL]It, by the way, works very well! However, I've now come across the fact that both the web page and the user controls will need to share a few Data Tables. In other words, both the web page and the user control will need to access and manipulate data in these data tables.
To implement this fact I've used the Session object to store each data table. Each of these data tables starts out empty and then starts growing as the user enters more data into the user controls. The initialization of the data tables has to be done in the web page for a series of technical reasons that I won't get into here but rest assured that it does have to occur there.
But I found that in order to ENSURE that the initialization was taking place, it was simplest to just pass a reference to each data table as an extra parameter in the LoadUserControl call. This does work but it seems like overkill to me because on the user control constructor side, nothing is actually done with the data tables at the time of instantiation of the user control.
This made me go back to basics, thinking, "Why include a parameter if you're not actually going to use it?" But yet, it does seem to be the most straightforward way to ensure the data table is initialized and stored in the Session object.
I have a Web User Control that holds many others User Controls. I'd like to name those embedded controls based on the ID of the parent user control.
I'm trying this code inside the main User Control:
<myLibrary:myChildUserControl1 ID="<%=ID%>" runat="server" />
or
<myLibrary:myChildUserControl2 ID="<%=ID%>_OkButton" runat="server" />
In both cases I get a compiler error.
Note that I have no problem assigning the control ID to regular HTML elements. The following code works well:
<div ID="<%=ID%>" >
I have a user control which has some properties configured on it. I need to access (actually, only read) the values of those properties on the client. I have done it like this.
Code behind:
[Code]....
ASPX:
[Code]....
That works but, at the back of my mind, I'm sure I've seen a neater way of doing it, although I suspect that may have been on an Extender not a User Control. Pointers on that welcome.
Also, related to that, the User Control itself has an Id which becomes part of the name of all visual objects included within it. However, the User Control is not a DOM element in its own right (because it has no visible rendering) which [I think] means that I have to attach properties to one of the visible elements within it, and not to the control itself?
I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).
I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

In my project, I need to create a user control to handle the sorting and pagination of all the grids in the application. The grid however will be different in different pages with different formatting.
I am able to do this by exposing a property from user control which takes gridview as the input.
then in page load, i bind this grid, and assign the sorting and paging event handlers to this gridview variable.
This way I am able to do the sorting and paging, but the problem is I have to bind the grid in all the post backs, and then in the sorting and paging events.
So when a user sorts, I have to bind the grid twice, once in page_load and then in sort event of user control.
I can store the first set of records in viewstate and bind that in page load, but is there any other way, so that i dont need to bind the grid in all post backs but only inside of not postback.
I have a user control inside a repeater. I am binding a collection of objects to the repeater.
My user control has a public property to retrieve the object (setobject)
How do i pass each object through to the user control and not just the object property value? What is the syntax to do this?

I did some google searching on this, but I could not find anything useful.
Basically what I am trying to do is pass some sensetive information to an ActionResult through the click of a HTML ActionLink.
The information I need passing through is, the ProductID and the User IP Address.
So just to clarify:
1) User clicks { I like Product } link (HTML ActionLink)
2) That sends the Product ID and the IP Address of the user to the ActionResult in the Controller.

View 1 RepliesThe MasterPage displays the NavBar for every page of my site.
The NavBar is constructed from a SQL table using a CustomSiteMapProvider.
I need to pass information from the MasterPage to the CustomSiteMapProvider to get it to display the whole SiteMap or only part of it.

I'm creating a pseudo invoicing system. I've got a webform where users can pick such informaiton as days, companies, etc to pull the information to create the invoice for and then they click a submit button. I'm wondering what the easiest method would be to get this information. I've had success with such commands as:
DropDownList SourceTextBox = (DropDownList)Page.PreviousPage.FindControl("DropDownList2");
but how can you pull this information through the SQLDataSource tools? When I choose to alter the "WHERE" in the sql clause to a control items in the previous page are not accessible.
i've one crystal report.i want the report header as "employee database".
i dont want to right click->insert and goto text object and insert.
i've one aspx page and aspx.cs page also.
now i want the "employee database" header to be printed from .cs file.
i dont want to pass by parameter also..
i.e is there any option in .cs file
something like ReportDocument myreport = new ReportDocument();
myreport.Load(MapPath("~/" + "emp.rpt"));
myReport.Reportheader="Employee database";
only thing is from .cs file i want to print the header as employee database.
i dont want by passing parameter also...ReportDocumentsasd myreport = new ReportDocument();
I have an Send.aspx page that has an uploadify control on it. Upload.ashx handles the file upload.I am adding a file record to a sql database in the Upload.ashx file and I need to get the ID of that record back from Upload.aspx when it is done.Can't get it working with Sessions. =( Something to do with an Adobe bug?
What would the best way to handle this be?Here is the uploadify control:
<script type="text/javascript">
// <![CDATA[
var contestID = $('[id$=HiddenFieldContestID]').val();[code]...
This took a while for me to figure out. But in retrospect it is extremely simple. For this reason, I mad a video tutorial to help newcomers get started quickly and understand how this awesome control works.

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?
