And this is my code for the button

But when I click the button it gives me this error
"Multiple controls with the same ID 'Label12' were found. FindControl requires that controls have unique IDs."
How do I give the controls unique IDs if they are in a gridview and the rows are database driven?

I've a web form named contest, where users are to register for it. When the register is clicked on, details entered by the user will be saved into the database, but before it will check if the user has already participated in the contest (using AJAX). If the user has already participated, the button will be disabled. The problem is there is an error when I click on the register button.
The error:

Ms SQL 2005 database I have a empty database at my hoster site. Its has nothing in it period. The admin's of the hosting site (asp.net 2.0) said send them a .bak file. .bak files are from "generate a backup" of a database in TOTAL. So I can see how a .bak file can restore a FULL database, but what about changing a stored proc?? Q1: The hoster admins only want .bak files to do tweaks to my database, so how does a .bak file acheive this for a just adding a table or a store proc only ? Q2: Some tables had data in them on my localhost, is there a way to generate a INSERT script for each data row and run this code at hoster site, or do I have to do an EXPORT from my localhost and an import at my hosting site?
View 7 RepliesI wonder how is it possible to manage transaction in c# code.. I have to do multiple insertion of same object with unique storedprocedure. So I have to launch the same stored procedure with same parameters multiple times.
But if a problem appear in the process (lost connection,...) I don't want just a part of insertions done and the rest failed, I want all the insertion cancelled. So I would like a SQLtransaction but within the application code because a can't change database.
Example code:
var div = new HtmlGenericControl("div");
div.Controls.Add(new Literal() { ID = "litSomeLit" });
var lit = (Literal)div.FindControl("litSomeLit");
Assert.IsNotNull(lit);
This code fails the assert, because lit is null. Debugging shows that div.Controls definitely contains a literal with ID of "litSomeLit." My questions are "Why?" and "Is there any way to get a control of a specific ID without doing a recursive search of div.Controls[] by hand one element at a time?"
The reason I'm doing things this way is that my actual application is not so straightforward- a method I'm writing is given a complex control with several subcontrols in a number of possible configurations. I need to access a specific control several layers down (eg, the control with ID "txtSpecificControl" might be at StartingControl.Controls[0].Controls[2].Controls[1].Controls[3]). Normally I could just do FindControl("txtSpecificControl"), but that does not seem to work when the controls were just dynamically created (as in the above example code).
I have a modal formview with insertitemtemplate. I have to click the insert button twice to fire the event.
But if I do not insert any values, only one click is required and the validationgroup fires. But if I enter all valid values, I need to click twice and the event does not fire during the first click. But I need CausesValidation = false because to required field validators.

I have a dynamic gridview in which i need to add textbox, checkbox, imgButton in the cell dynamically.
At the moment user click on the imbgutton, a click event fire and i need to capture the user input on the checkbox and textbox of the particular cell.
I have problem in finding out the checkbox and textbox control in the imgbutton click event. The cause is i do not know which row in the gridview i need to search to for the control.
I have try gridview.Fincontrol but fail.
using the GridView FindControl.
What I've done is I've setup a Gridview with a datasource to show only 1 of the columns I need from the datasource, but I also have another ItemTemplate Column in which I have a dropdownlist with another datasource that I've bound to the dropdownlist.
What I need to do is have the dropdownlist show the selected one when compared to a id from datasource in the gridview.
i have button field in grid view, basicly i want to show to in some of the row only, but i cant find the "ID" using find control

In my gridview, I have an ImageButton and when the user clicks it, I show a modal, however, when I popUp modal its showing me the same Datakey value for each row, so, is there a way to use FindControl for the selected row within the RowCommand?
View 5 Repliesthis is probably very simple but I'm tearing my hair out!I'm using the FindControl method to try and grab the text in a textbox inside a DetailsView Template Field and display it on a label. Here is my code:
[Code]....
The word text has a squiggle underneath though and it causes an error as "System.Web.UI.Control' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)". I know the problem is that I'm treating this Control as a TextBox when it isn't, it's a Control. So how do I get from Control to TextBox so I can take the String and use it in code?
I thought I had this all figured out, in fact the following is similar to another page I have that works, but dinged if I can see what is wrong with this.I have a FormView with the InsertItem Template as the default. I have a label "UserId" that is assigned the logged on user's userid on page load with:
LblUserID.Text = Membership.GetUser.ProviderUserKey.ToString , which I am certain works.
There is a textbox "User_IDTextbox" within the InsertItem Template of a FormView, and I am trying to write the UserID into that text box using this VB code in a subroutine:
Dim TxtBxUserIDParent As TextBox = DirectCast(FVAddTradeResort.FindControl("User_IDTextbox"), TextBox)
TxtBxUserIDParent.Text = LblUserID.Text
This does not result in populating the textbox within the InsertItem Template of the Formview template with the UserID
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "UPDATE M_t1 SET c_name=@c_name WHERE id=@id";
cmd.Parameters.Add("@id", SqlDbType.Int).Value = (Label)Convert.ToInt32(grdmsal.Rows.FindControl("Label1").Text);// //(Label)grdmsal.Rows.FindControls("Label1").Text;
cmd.Parameters.Add("@c_name", SqlDbType.VarChar).Value = ((TextBox) grdmsal.Rows[e.RowIndex].Cells[2].Controls[0]).Text;
