View 2 RepliesI am facing a problem with page button evet handling in routing. Sceneario: Page2.aspx is routed to page1.aspx. now when I see the page1.aspx in runtime it shows page name as page1.aspx but content displayed is page2.aspx. In HTML markup it is displaying page1.aspx code. Now the problem is I have a button on page2.aspx. How can I fire event so that it executes the event in page2.aspx and again comes back normally after postback to page1.aspx which contains content of page2.aspx.
View 2 RepliesI'm a new developer here, working in VB. Have a question that is stumping me as well as some others.
I have a gridview control built. I am not using an <sqldatasource> tag, so I can't use it's autoGenerateSelect/Update/Delete functionality. I have built a template field that has an "edit" link button in it, and by clicking it will fire the grdName_SelectedIndexChanged event of the gridview.
Now, it's in this event where I'm having trouble. I have it coded so that when this event fires, it will build a textbox and button control. Code:
Protected Sub grdResults2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdResults2.SelectedIndexChanged
Dim row As GridViewRow = grdResults2.SelectedRow
Dim cell As TableCell = row.Cells(6)
Dim txtSeq As New TextBox
Dim btnUpdate As New Button
'build the textbox in the Search_Seq cell
txtSeq.ID = "txtSeq"
txtSeq.Width = Unit.Pixel(20)
txtSeq.Text = row.Cells(6).Text
cell.Controls.Add(txtSeq)
'build the "update" button in the Search_Seq cell
btnUpdate.ID = "btnUpdate"
btnUpdate.Text = "Update"
cell.Controls.Add(btnUpdate)
End Sub
So the textbox and button populate perfectly. I can run it in the browser and it works fine.
How do I go about setting up the event for this button now? Because it's being manually built here in the gridview event, there is no button for me to "double_click" on in the design view to auto-build this event. There are some properties that need to be set on this button to link it up to a new event....and that's where I'm lost.
Hopefully I don't leave any additional information out.
How to fire a button click event inside a grid view.
View 2 RepliesOn grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TableCell cell = new TableCell();
ImageButton bttn = new ImageButton();
[Code]...
That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click);
private void b_Click(object sender, EventArgs e)
{
//delete record
}
but this above code also not working.

I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
below is code:
<asp:GridView ID="GridView1" runat="server" CssClass="DGridView1"
AutoGenerateColumns = "false" Font-Names = "Tahoma"
Font-Size = "9pt"
HeaderStyle-BackColor = "#e0e0e0"
OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
GridLines = "Both" OnRowDataBound = "OnRowDataBound"
>
And .cs:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label Label3 = (Label)GridView1.Rows[e.NewEditIndex].FindControl("Label3");
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
but here when I click on EditCustomer it doen't change label3.text
im using javascript like
var TargetBaseControl = null;
window.onload = function()
{
try
{[code].... //get target base control.

hen i run the page and click the button then no more further processing just button has been click nothing happan......
There is nothing fancy with the mark-up:
<hr />
Add... <asp:Button ID="buttonTextSegment" runat="server" Text="Text Segment"
onclick="buttonTextSegment_Click" />
<hr />
Or the code:
protected void buttonTextSegment_Click(object sender, EventArgs e)
{
//never is triggered
}
My guess is that it is due to the hierarchy/load order:
In English: Inside the page's Load, it adds a user control. Inside of that user control, inside of Page_LoadComplete (is this the issue!?), it adds another user control, it is the inner-most user control that contains the mark-up button.
Pseudo Visually: Page -> Page_Load: Dynamically Added User Control -> Page_LoadComplete: Another Dynamically Added User Control -> User Control Mark-Up: Button with event.
Do events need to be hooked before LoadComplete? (Is there a way to make events still work even though the controls are added in LoadComplete?)

I am developing a web site to display some data that is inside a database. To do this I've created an ASPX web page that opens a connection to a database and retrieves the desired data. After that it populates an asp:table object dynamically.
The problem is that some of the fields that are retrieved from the database are too large to be displayed on the web page, so I decided to make a popup that would be able to display just the desired field.
To do this I've added a button to the asp:table so that when the user clicks it the popup would appear with the contents of the field. However what is happening is that when the user clicks on the button, the page just gets reloaded and the Click event handler is never called.
Below is the code in which I add the button to a TableCell, and the TableCell to the TableRow collection:
[Code]....
note that the popupHandler is a delegate to the function below. I am using it as a the Click event handler for testing purposes.
[Code]....
Also you should be aware that the table is only populated when the user clicks on a "Query" button inside the main ASPX web page, this means that I only populate the table after the PageLoad event has occurred.
I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:

I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.
