Gridview structure looks like this:
MANUALLY_ADDED_ROW
NORMALROW <= enter value here works
MANUALLY_ADDED_ROW

Web Forms :: Can't Get Button Click EventHandler To Fire

Jun 14, 2010

I'm adding a Button to a TableCell dymanically in code-behind and cant get an event handler to work.

Here's some code...

Button b = new
Button();
b.Text = "Go";
b.Click += new
EventHandler(OnSequenceChanged);

Web Forms :: Does Pageload Command Override Eventhandler?

Oct 14, 2010

On page load I have this:

LinkButton1.Attributes.Add("onclick", "window.open('EditClients.aspx','','height=700,width=600');return false")

I also have an event handler for LinkButton1:

Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LinkButton1.Click
Label8.Visible = True
RefreshButton.Visible = True
End Sub

The problem is the event handler is ignored. Label8 and RefreshButton do not becoem visible when clicking Linkbutton1, but the new window opens fine. How can I make all things happen?

Feb 24, 2010

A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:

[Code]....

I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.

Forms Data Controls :: Dynamically Add A Button With An Eventhandler To A Specific Cell In Gridview

Mar 10, 2010

I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.

C# - Dynamically Added ListBox's EventHandler Is Not Firing?

Nov 20, 2010

The scenerio is I have a UserControl. This user control will create dynamically ListBoxes if the given List's count > 0. The controls are adding dynamically, there is no problem with adding them, but the event handler is not adding. If I select an item in first listBox, the secondListBox will be added dynamically, and items will add dynamically too. First listBox appears, but the selectedIndexChanged event handler doesn't work. What can be the problem with my code?

EDIT: I tried to add

li.Attributes.Add("onselectedindexchanged","selectedIndexChanged");

or

li.AutoPostBack = true;

but still not firing...

private List<string> myList = new List<string>() { "Serkan", "Kadir" };
private List<string> mySecondList = new List<string>() { "Istanbul", "Ankara" };
protected void Page_Load(object sender, EventArgs e)
{

Forms Data Controls :: Dynamic Gridview EventHandler Sees All WebForm Controls As Null

Mar 30, 2010

I have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.

EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole =
new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi
is the webform code behind partial class.
CheckBox chk =
new
CheckBox();
chk.ID = _columnName;
chk.DataBinding += new
EventHandler(chk_DataBinding);
//Attaches the data binding event.
chk.AutoPostBack = true;
chk.CheckedChanged += new
EventHandler(ealmsapprole.Dyn_CheckChanged);
container.Controls.Add(chk);
chk.Enabled = true;
This is the code for the event Handler
internal
void Dyn_CheckChanged(object sender,
EventArgs e)
{
string err =
"";
try
{
if (lblAppID.Text !=
"")
}

that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.
