The problem here is sometimes it will not trigger RadGrid1_BatchEditCommand. Please help.
I have codes below at javascript:
var grid = $find("<%=RadGrid1.ClientID %>");
var batchManager1 = grid.get_batchEditingManager();
var hasChanges = batchManager1.hasChanges(grid.get_masterTableView());
if(hasChanges) {
grid.get_batchEditingManager().saveChanges(grid.get_masterTableView());
}
else{
args.set_cancel(true);`
window.close();
}
I have code below at code behind:
protected void RadGrid1_BatchEditCommand(object sender, GridBatchEditingEventArgs e)
{
enter code here
}
I do this in my case.
var grid = $find("<%=RadGrid1.ClientID %>");
var batchManager1 = grid.get_batchEditingManager();
grid.get_batchEditingManager().saveChanges(grid.get_masterTableView());

I'm using ASP to look for the selected value in a dropdown box. The dropdown box choices are generated at load time. Here is the JavaScript for that:
function CreateDepartmentDropdown(data) {
var dropdown = document.getElementById("department_dropdown");
for (var i = 0; i < data.length; i++) {
var array = data[i].split(',');
var option = document.createElement("option");
option.value = array[0];
option.innerHTML = array[1];
dropdown.add(option);
}
}
And it looks like this:
Looks fine to me. Then I checked the HTML out too just to be sure:
That looks great too. Now here is where the issue comes up. When I press submit this delegate fires in C# (still only testing while making this):
void Activity_Submit_Click(object sender, EventArgs e)
{
int fye = Int32.Parse(fye_dropdown.Value);
String activity_name = activity_name_field.Value;
String activity_responsible = responsible_field.Value;
int department = Int32.Parse(department_dropdown.Value);
String activity_start = datepicker_start.Value;
String activity_end = datepicker_end.Value;
}
And when I debug this it stops at department saying that it's malformed. Looking at department_dropdown.Value in the immediate window turns up an empty string and the dropdown itself has 0 children.
Why would this return an empty response when the list is clearly there? How would I go about fixing this?
The client-side items won't get posted back to the server like this.
The easiest way is to Serialize the array as Json, put it in a hidden input element's value :
In your markup:
<asp:HiddenField runat="Server" ID="department_dropdown_items" cssclass="department_dropdown_items" />
<asp:HiddenField runat="Server" ID="department_dropdown_selected" cssclass="department_dropdown_selected" />
Your Javascript:
function CreateDepartmentDropdown(data) {
var dropdown = document.getElementById("department_dropdown");
for (var i = 0; i < data.length; i++) {
var array = data[i].split(',');
var option = document.createElement("option");
option.value = array[0];
option.innerHTML = array[1];
dropdown.add(option);
}
$(".department_dropdown_items").text(JSON.Stringify(data));
}
$(document).ready(function() {
$("form").submit(function(e) {
$(".department_dropdown_selected").text( $("#department_dropdown").value);
});
});
then use it in the code behind:
void Activity_Submit_Click(object sender, EventArgs e)
{
string[] data = new JavascriptSerializer().Deserialize<string[]>(department_dropdown_items.Value);
string selectedValue = department_dropdown_selected.Value;
int fye = Int32.Parse(fye_dropdown.Value);
String activity_name = activity_name_field.Value;
String activity_responsible = responsible_field.Value;
int department = Int32.Parse(department_dropdown.Value);
String activity_start = datepicker_start.Value;
String activity_end = datepicker_end.Value;
}
The code is not tested. Tell me if it's not working :)
So I ended up doing the following:
Make a Hidden asp element called department_dropdown_selected_value
Then in a Script tag I made the following function:
.
function GetDepartmentDropdownValue(sel) {
var hidden_field = document.getElementById('department_dropdown_selected_value');
hidden_field.value = sel.value;
}
Then in my HTML I did this: <select class="form-control" id="department_dropdown" onchange="GetDepartmentDropdownValue(this)">
Then I can just simply do this in C#: int department = Int32.Parse(department_dropdown_selected_value.Value);
Please help! i have been trying to call this function on my Asp.net textbox to format users input while typing.
function format(number) {
var decimalSeparator = ".";
var thousandSeparator = ",";
var result = String(number);
var parts = result.split(decimalSeparator);
if (!parts[1]) {
parts[1] = "00";
}
result = parts[0].split("").reverse().join("");
result = result.replace(/(\d{3}(?!$))/g, "$1" + thousandSeparator);
parts[0] = result.split("").reverse().join("");
return parts.join(decimalSeparator);
}
// i tried using onkeyup, it didnt work
<asp:TextBox ID="txtTransport" runat="server" CssClass="TextBoxes" onKeyup="javaScript: format(this);"></asp:TextBox>
// also i tried using onChange, it didnt work.
<asp:TextBox ID="txtTransport" runat="server" CssClass="TextBoxes" onChange="javaScript:format(this);"></asp:TextBox>
protected void Page_Load(object sender, EventArgs e)
{
txtTransport.Attributes.Add("onKeyup", "javaScript: format(this);");
}
You can do it directly from javascript, not in codebehind !
var el = document.getElementById("<%= txtTransport.ClientID %>");
el.onkeyup = function(e) {
// Do stuff
};
But I think your function is logicaly wrong. Try it anyway. Your ID of a server side control is not exactly the same you write in the code, for get the real ID you can use <%= txtTransport.ClientID %>.
It is my Vb.net code it works perfectly.
Protected Sub ChkTaxCheckedChanged1(ByVal sender As Object, ByVal e As EventArgs)
Dim chkTax As CheckBox
Dim gv1 As GridDataItem
chkTax = TryCast(sender, CheckBox)
gv1 = DirectCast(chkTax.NamingContainer, GridDataItem)
Dim txtAmount1 As Label = CType(gv1.OwnerTableView.ParentItem.FindControl("lblItemAmount"), Label)
End Sub
But now I want to achieve the same functionality in clientside using JavaScript.
Like :
function ChkTaxCheckedChanged1(sender, args) {
var check = sender.get_parent()..??????
}
Any one know how can I do this?
Try this.
<script>
function handleClick(sender,args) {
//i have used jquery so do not forgot add jquery reference
var checkboxid = sender.get_id();
var parentRow = checkboxid.parent().parent().parent().parent().parent().parent()[0].previousSibling;
$(parentRow).find('span').html('Your text comes here');
}
</script>
I'm using div instead of iframe to call a page but as soon as the other page loads in div then after clicking on any button, or selecting radiobutton, these events give this error
This is how I load div
<script type="text/javascript">
$(function () {
setInterval(function () {
$('#result').load('frmChatRequest.aspx', function () {
});
}, 10000);
});
</script>
This is frmChatRequest.aspx.cs page
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
dt_chatRequest = LookupChat.getPendingRequestInMyChat("",Int64.Parse(_objSession.LoginID), _objSession, _errMsg);
ClsDataBind.DoGridViewBind(gdvChatRequestRoom, dt_chatRequest, _errMsg);
myMarqueeChatRequest.InnerText = "You Have " + dt_chatRequest.Rows.Count.ToString() + " new chat request/s in your rooms in last 15 minutes";
}
}
protected void gdvChatRequestRoom_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Accept")
{
HiddenField hdn = ((HiddenField)gdvChatRequestRoom.Rows[0].Cells[0].FindControl("hdnAddPeople"));
string strHdnValue = hdn.Value;
//Button btn = ((Button)gdvChatRequestRoom.Rows[0].Cells[3].FindControl("btnAccept"));
//string strBtnID = btn.ID;
string strBtnID = e.CommandArgument.ToString();
string query = "select * from Q116 where Q116002="+strBtnID+ " and Q116001="+ hdn.Value ;
_objQ116.SelectAll(query);
_objQ116.Q116DF2 = _objSession.LoginID;
_objQ116.Update(_objQ116.Q116DF2);
_objQ116.SelectAll(query);
_objQ116.Q116004 = DateTime.Now.ToString("hh:mm:ss");
_objQ116.Update(_objQ116.Q116004);
//insert in Q119
// _objQ116.Update(Q116004);
//_objLOG2.SelectAll(query);
//DateTime dt1 = DateTime.UtcNow.AddHours(5.5);
//string str = dt1.ToString();
//_objLOG2.Update(str);
//Write code to add to card
}
if (e.CommandName == "Reject")
{
HiddenField hdn = ((HiddenField)gdvChatRequestRoom.Rows[0].Cells[0].FindControl("hdnAddPeople"));
string strHdnValue = hdn.Value;
//Button btn = ((Button)gdvChatRequestRoom.Rows[0].Cells[3].FindControl("btnAccept"));
//string strBtnID = btn.ID;
string strBtnID = e.CommandArgument.ToString();
string query = "delete from Q116 where Q116001=" + hdn.Value + " and Q116002=" + "'" + strBtnID + "'";
// _objQ116.SelectAll(query);
Educity.EduDB.Select(query);
//Write code to add to card
}
Response.Redirect(Request.Url.AbsolutePath);
}
The ASP.NET webforms JavaScript and markup is probably messing up the hosting page and this is why a whole page is normally loaded in an iframe.
Have you considered using custom controls? They are really easy and encapsulate functionality into objects that can be included in any web page. It looks like frmChatRequest would be better as a control. Building a custom control is very similar to building a aspx webforms page, but it can then be re-used.
For more info on custom controls see http://msdn.microsoft.com/en-us/library/zt27tfhy.ASPX
I have an Asp server control button for which I have onClick for processing code in code behind and onClientClick to process javascript code. The codes are:
Update: As per Icarus solution, updated codes :
Button source:
<asp:Button ID="Button1" runat="server" onclick="Button1_Click"
style="z-index: 1; left: 648px; top: 202px; position: absolute"
Text="Show route" OnClientClick="droute(); return false" />
<asp:HiddenField ID="hdncroute" runat="server" />
Code behind:
protected void Button1_Click(object sender, EventArgs e)
{
using (con = new MySqlConnection("server=localhost; uid=root;password=as64ws;database=Gmaps"))
da = new MySqlDataAdapter("select * from routes where uid='" + Session["uname"].ToString() + "'", con);
da.Fill(ds, "mroute");
foreach (DataRow r in ds.Tables[0].Rows)
{
uroute.Add(r["latlng"].ToString());
}
croute = new string[uroute.Count];
croute = uroute.ToArray();
hdncroute.Value = string.Join("&", croute);
}
Javascript function:
function droute()
{
var route=[];
var temp;
temp = eval(document.getElementById('<%= hdncroute.ClientID %>').value);
route= temp.split('&');
//Polyline icon n line settings
var iconsetngs= {path:google.maps.SymbolPath.FORWARD_CLOSED_ARROW, fillColor:'#FF0000'};
var polylineoptns= {strokeColor:'#3333FF',strokeOpacity:0.8,strokeWeight:3,map:map,icons:[{icon:iconsetngs,offset:'100%'}]};
polyline= new google.maps.Polyline(polylineoptns);
//Loop to add locations and draw line
var path= polyline.getPath();
for(var i=0;i<route.length;i++)
{
var marker= new google.maps.Marker({position:route[i],map:map});
path.push(route[i]);
google.maps.event.addListener(marker,'click',showiwindow);
}
//Event Listener's
function showiwindow(event)
{
iwindow.setContent("<b>Coordinates are:</b><br/>Latitude:"+event.latLng.lat()+"<br/>Longitude:"+event.latLng.lng());
iwindow.open(map,this);
}
}
I know that writing return false for javascript function will avoid refresh, and also onClick has void return type. But still my page reloads on button click.
You have an error here:
route = document.getElementById('<%= croute %>').value;
It should be:
route = document.getElementById('<%= croute.ClientID %>').value;
Update:
Markup - declare a hidden element in the page
<asp:hiddenfield id="hdnCroute" runat="server" />
//code behind
int [] croute = ...
hdnCroute.Value = "["+string.Join(",",croute)+"]";
Now Javascipt:
//now you have an array back in javascript
var route= eval(document.getElementById('<%= hdnCroute.ClientID %>').value);
why the page reload?
OnClientClick="droute(); return false"
at inner of browser like this:
button.onclick = function(){
droute();
return false
};
while droute is going wrong,so,return false doesn't work.
