Forms Data Controls :: Adding Onclick Event To A Checkbox?
Jul 1, 2010
I have a checkbox inside a repeater like below..I'm having trouble figuring out how I need to tie the onclick event to a javascript function..I know I need to use somthing like
butSubmit.Attributes.Add("onClick", "return confirmSubmit();") but Since my checkbox is inside a repeater and I'm using master pages. I'm not sure how I need to use the findcontrol to so I can call the Add method?
I need to add an onclick to the ChkAll checkbox

I've just slapped together a new user control and I need to add a OnClick event to it so I can handle it via page code behind.
I've never had to do it before so if someone would be kind enough to shead some light that'd be fantastic.

I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}
But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}
I get no CheckedChanged event.
Is there a possibility to get:
- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row

The <ItemTemplate> loads properly, and the line:
<asp:LinkButton ID="generalcomments" OnClick="SetPage_N_of_All" runat="server" PostBackUrl=<%#DataBinder.Eval(Container.DataItem, "Filename")%>> <%#DataBinder.Eval(Container.DataItem, "Title")%></asp:LinkButton>
loads the page correctly, BUT it does not fire the onClick event (OnClick="SetPage_N_of_All").
The method SetPage_N_of_All is in the codebehind page and is as follows:
public void SetPage_N_of_All(object sender, EventArgs e)
{
ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpTextBox = (TextBox)this.Master.FindControl("page_N_of_All.Text");
mpTextBox.Text = RobertBurns.DPM_Current.page_N_of_All;

How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.

I have a datalist control that is querying a accessdatasource for information that populates the results based on w/e is typed in a textbox. I can't figure out how to pass the information that is populated in the datalist to another page when a button is clicked (inside the datalist item template).
I was able to peform this in Detailsview with a hyperlink using the following arguments:
DataNavigateUrlFieldsDataNavigateUrlFormatStringBut this seems not to exist in Detailsview. Could someone point me in a direction on how to acomplish this?

I have a gridview in my aspx page, which is filled with data from generic list.
I want to add a checkbox and a link button in the grid, so that users can select the row and when users click on the link button, a new page is loaded with the items in the selected row.

I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
