View 1 RepliesI have multiple HyperLink controls and I want to enable or disable different panels base on which HyperLink I clicked on. This should be done using javascript. The question is: Is that possible to even use javascript for this? I know other button controls, there is onClick property but not in Hyperlink.
View 5 RepliesI have a web form in which I create many controls including a submit button dinamically.
I want to check a condition in the button's click event and if it comes true, call a javascript funtion to show an alert. but the problem is when I use :
Page.RegisterClientScriptBlock("ClientScript", script);
in the btn_Click event, it is not working. I guess the script should be registered at page_load.

if (!exist)//exists is the query
{
System.Web.UI.Control my = FindControl("a2");

I have a GridView that shows results according to user selections above it via checkboxes, dropdown lists etc. Once user clicks on a hyperlink value on one of the rows in GridView, user is taken to another page which is sort of a drill down for that line item in the GridView.
Everything works fine so far, except when the user hits the back button, user selections that filter data on the Gridview page are lost. So, I added ViewState="True" on these filter options (i.e. checkbox, dropdownlist etc.). When back button is hit selections were still cleared. How could I remedy this?
how to call a partial view from within a Javascript function? I've looked around the web, but all the examples that I have been able to find are examples using Ajax.ActionLink or Ajax.BeginForm.
When a user clicks on an item, I want to be able to hide/display some Divs and possible do other operations before calling the partial view. ActionLink doesn't appear to provide that ability. Depending upon the item the user clicked, I may be assigning the results of the PartialView to the same Div, or to a different Div.
What I'm looking to achieve, is to have an onclick handler associated with the item which performs whatever other operations might need to be done, then assign the result of the call of the PartialView to the appropiate Div. In some instances, the function might even be making two separate calls to PartialViews, to update the content of two separate Divs.
I want to hyperlink from a field in one gridview to a field in another gridview based on id. I've tried many ways but haven't seen success.
View 20 RepliesI have a gridview which contains a mix of boundfields and hyperlinkfields ..
Using the below code (VB) for testing purposes only :
Dim row As GridViewRow = GridView1.Rows(0)
MsgBox(row.Cells(3).Text.ToString)
if the cell contains a boundfield, the msgbox will contain the cell value
if the cell contains a hyperlink field, the msgbox will always be blank !

I am trying to call a Page Method using AJAX.
See the code
<asp:Button ID="btn_upload" runat="server" CssClass="btnEffects" Text="Upload"
onclick="btn_upload_Click" OnClientClick="return Validate();" />
Validate method is supposed to return true/false. The code for Validate method is
<script language="javascript">
function Validate()
{
var filename = $get('<%= txt_filename.ClientID %>').value;
PageMethods.IsValidFile(filename,OnSuccess, OnFailure);
// IsValidFile is a Page Method of bool return type
}
function OnSuccess(result)
{
if ( !result)
{
alert('File '+ $get('<%= txt_filename.ClientID %>').value + ' does not exist');
return false;
}
else
{
return true;
}
}
function OnFailure(error)
{
}
</script>
My problem is that even after showing the alert 'File somefilename does not exist'. The whole page refreshes (i.e, postback happens)
I want to return single field to a different webpage using hyperlink.

I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

I have overridden OnError method in the page:
public string script;
protected override void OnError(EventArgs e)
{
script = "alert('error');";
}
In the aspx, I have this:
<script type="text/javascript">
$(document).ready(function(){
<%=script %>;
});
</script>
I am simulating an error in Page_Load, but its not firing the alert. If I switch the code from OnError to OnLoad, it works great.
I am working with vs 2008 and C#. I am having a code behind function as follows(not complete)

string setofalllatsandlongs = null;
foreach (string s in ar)
{

</div>In thIn the click event of the btnShowZone(in bold) i am calling the code behind method and from that i am trying to call the js function using the script manager class.
But the javascript method is not getting called.the control is not going to the js function.
I have a script manager and calendar extender on my aspx page. When I call a javascript function from my code behind page, the calendar extender doesn't work
ScriptManager.RegisterStartupScript(Page, this.GetType(), "javascriptfunction", "<script language=javascript>function();</script>", true);
OR
Page.ClientScript.RegisterStartupScript(this.GetType(), "javascriptfunction", "<script language=javascript>function();</script>", true);
