Forms Data Controls :: Get Row Status Of DataGrid In User Control Page From ASPX Page?
May 15, 2010
My Question is related to access the rows in one page and putting conditions in another page.I need to check whether a datagrid has row in it or not. DataGrid is in .aspx page. Based on this checking i need to write a condition in .ascx page.the .ascx on which condition is checked is linked to .aspx page. Meaning that UserControl1.ascx is Register with Default.aspx pageI am using VS 2003let me know if any input is needed from my side.
but it is throwing as exception Object reference not set to an instance of an object.How can I access user control's gridview control from parent page?
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 also have a working application that popukates my datagrid with valid data rows from my DataBase. What I cant figure out is how to get each of the hyperlink lables to NAVIGATE to the correct and corresponding aspx page!
For example I have 5 rows in the datagrid and each row has its own hyperlink, each row contains contact and a short profile on 5 diffrent companies. For example when i click on let say row 3 that has (eg) Jimmy's Big Prawn's Restaurant listed in the the datagrid, I want to be navigated to a webform page dedicated to Jimmy's Big Prawn Restaurant.
[Code]....
I am guesing it has to do with the bolded text above, but "details.aspx" is just an empty webform, I would like the hyperlink to point to (eg) JimmBigPrawnRestaurant.aspx.
I have a lebel in a UserControl with the name lblAmount and a textboxt in an ASPX page. now i want to assign the value of lblAmount (Lebel in UserControl ) to the text box of the page
I have a windows user control simpleusercontrol.ascx which has a button control which when clicked calls a delegate method as shown below:
[Code]....
Now this control is embedded inside an aspx page by using <object> tag i.e. by creating a dll of the above project. (Please note that it is the requirement of the project as javascript needs to be called from the embedded windows user control onto the hosting aspx page).So,
[Code]....
This works perfectly fine when I run the project in VS.Net by pressing F5 ie by using VS.Net inbuilt web server. However problem arises when I try to run the same project by creating a virtual directory and calling through localhost.
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.
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.
I have the windows form user control with the name usercontrol.cs .. I want to display this usercontrol.cs in aspx page..I tried the below code..but it produced error.. how to resolve my proplem...thx

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.
I have a button control called "btnAdd" located at a cuser control. I am using the usercontrol in an aspx page. I need to create a new button control in the aspx page that reference to the button control (btnAdd) located in the user control , so I can use its code in the aspx page.
Im trying to find out how to use the web user control .ascx with the Aspx page..
Yes I do know how to create this and drag it into the aspx page...
But I want to go a step further ,...
I want to use a dropdownlist in the aspx page
Gridview in ascx thats databind in the ascx.vb file
...........then when selecting a value in the dropdownlist (in aspx)....it changes the sql query in the ascx file and show the new data in the user control..
I have tried to look for examples...everything I found was not making sense..poor explained and the codes where all in C#..so when converting it the examples dont even work..

i would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
and in the rows under column there are figures like:
30, 50, 28 65, 0, 214 etc.
My program is working fine, when I am clicking 30, a new page opens and displays 30 rows, when I click 28 another page opens and displays 28 rows and so on.
In datatable there is a column named Stauts, actually Pending, Waiters,Opened are the status.
In dataset in table adapter I used thress queries one for "Pending", second for "Waiters" and third for "Opened".
To display data I created three pages with gridviews.
I used query like:
Select * from ..... Where status ='Pending' Select * from ..... Where status ='Waiters' Select * from ..... Where status ='Opened'
What is Required:
I want to make one query with status =@status and want to use header name in query or in vb.net coding and want to make only one page to display record.
To put my question as an idea/example I used three status but in real scenarion I have lot of status. If I have lot of status so I have to make lot of queries and have to create lot of aspx pages to display data in gridview that is not the correct logic.
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 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.
