I have an aspx web application in which 1 aspx page and 1 web user controls exist. I added 4 instances of the user control in aspx page. There is a remove button in user control which is used to remove the control from the aspx page. If I click on remove button of the user control, how can I find that which user control's remove button is clicked from the aspx page.

View 2 RepliesI have on dropdown that show hide user control. In the user control i have Ok and Cancel button.
When the dropdown change i want to apply ValidationGroup on the Ok button that is inside UserControl.
On masterPage i have button btnTest, how hide button from masterPage on userControl.ascx
example:
btnSecondPage_click
{
btnTest.visible = false;
}
So all I want to do is simply find a user control I load based on a drop down selection. I have the user control added but now I'm trying to find the control so I can access a couple properties off of it and I can't find the control for the life of me. I'm actually doing all of this in the master page and there is no code in the default.aspx page itself.
MasterPage.aspx
[Code]....
MasterPage.cs
protected void goToSelectedPage(object sender, System.EventArgs e)
{
temp1 ct = this.Page.Master.LoadControl("temp1.ascx") as temp1;
ct.ID = "TestMe";
this.UpdatePanel1.ContentTemplateContainer.Controls.Add(ct);
}
//This is where I CANNOT SEEM TO FIND THE CONTROL ////////////////////////////////////////
protected void lnkSave_Click(object sender, System.EventArgs e)
{
UpdatePanel teest = this.FindControl("UpdatePanel1") as UpdatePanel;
Control test2 = teest.ContentTemplateContainer.FindControl("ctl09") as Control;
temp1 test3 = test2.FindControl("TestMe") as temp1;
string maybe = test3.Col1TopTitle;
}
Here I don't understand what it's telling me. for "par" I get "ctl09" and I have no idea how I am supposed to find this control. temp1.ascx.cs
protected void Page_Load(object sender, EventArgs e)
{
string ppp = this.ID;
string par = this.Parent.ID;
}

I'm trying to programmatically add a user control to an aspx page.
the problem is that any postback that happens on the page(even if i added the user control to an updatepanel) clears the user control from the page.
this happens also if the postback is generated from the user control itself.
I have an aspx webpage in which an user control is added dynamically as follows:
UserControl testUsrControl = LoadControl("TestUsrControl") as UserControl;
testUsrControl.ID ="test";
Then I tried adding an event handler of user control inside aspx like below:
testUsrControl.Drpdatafield_SelectIndexChanged += new EventHandler(this.Drpdatafield_SelectIndexChanged);
But this line is giving error at **testUsrControl.Drpdatafield_SelectIndexChanged **. The error is "Drpdatafield_SelectIndexChanged" doesn't exist in UserControl.How can get the testUsrControl's events inside aspx page dynamically.
I am working on a page called Edit.aspx and on that page is a User Control.
Note: I need to access the User Control from a button that is on the Edit Page. Once I get a handle of the User Control then I need to access a DataList on that user control and finally I need to get the ID of a dropDownList
on the User Control
This is all the code I have,Goal: From the Edit page I want to drill backwards to the UserControl/DataList/DropDownList
'Geting the user control
Dim ctrl2 As UC_SiteTemplate2 = CType(Page.LoadControl("~/UC/SiteTemplate2.ascx"), UC_SiteTemplate2)
'accessing drop down list from user control
Dim xListNumber1 As DropDownList = New DropDownList()
xListNumber1 = ctrl2.FindControl("DDLOrderList1")
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
[code]....
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.
There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?
I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.
<linkbutton><label>button text</label></linkbutton>
I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.
As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.
As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.
Click triggers > Button_Click > ButtonControls > MethodToCall
sometimes I don't want to call Button_Click just an event on the aspx page itself rather than my generic button handler.

View 1 RepliesI'm writing applications on Facebook located on an external website ASP.NET C #. The application should check whether or not a person likes my Fan Page (page) on Facebook, and if he or she doesn’t like it needs to like it before using this application. How this can be done using the Graph API and ASPSnippets Facebook API.
View 1 RepliesHere is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
I want to move some parts of the html page containing this function to a new web user control. now "form1" is not defined and it is not working correctly without any error message!
