C# - Get Label Value As A Parameter Into A Javascript Function?
Jul 9, 2010
Hopefully this one is not too hard to understand but I just want the label values to be inputs into a javascript function. Might be better to explain with code: ASP.NET Label code:
<asp:Label ID="LabelCL" runat="server" Text="A single int filled in by DB"></asp:Label>
Page Source:
<span id="ctl00_cpMainContent_LabelCL">7</span>
What I would like to achieve but am not sure how to do:
I tried to pass a string value into a JavaScript function like below: <%= "'" + prop.property_description + "'") %>) But it does not seems to be the best option, is there a better way to do the above without concatenate the string values with "'"?
Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window. All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.
JavaScript Function function RefreshParent(inputDate) { window.opener.location = window.opener.location + "?Date=" + inputDate; } .NET Code-Behind Protected Sub RadGridOnlineRequests_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGridOnlineRequests.ItemCommand If e.CommandName = "ViewOnlineRequest" Then ' populates LabelScheduleDate among other controls values ScriptManager.RegisterStartupScript( _ Me, Me.GetType(), "clientScript", "RefreshParent(" & LabelScheduleDate.Text & ");", True) End If End Sub
I want to call javascript function on label onload, reason I am using an enitity Datasource and assignng a value to this label, but I want to hide it if the value is empty.
I have a button inside my <ItemTemplate> in GridView and I want to call a javascript function on the OnClientClick of that button passing the DataItem value as a parameter of the javascript function
[code]....
If I will not put a parameter in CreateEditAddess() this works well but I need the parameter.
I know I can put the OnClientClick event value in OnRowDataBound event of the gridview but I don't want to put it in CodeBehind. It seems like the server tag is not parsed correctly.
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" > hi ihave this functin in .vb file Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click end sub
instead of returning my output paremeter value in my stored procedure to my label it returns the default value i set my output parameter to. why cant i put my output parameter into my text label
Dim reader As SqlDataReader cmd.Parameters.AddWithValue("@tour", "2365") cmd.Parameters.Add("@tourname", SqlDbType.VarChar) cmd.Parameters("@tourname").Direction = ParameterDirection.Output
I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.
In asp.net page, How can i call the javascript methods for form processing-submitting if the user browser supports javascript and use code behind events if the browser does not support javascript.I have the javascript code to send the form data to an ajax server page using jquery. Don't know how to invoke the needed one based on the browsers javascript availability
I'm using ajax to call a webmethod from javascript. The call is successfully made to the webmethod but I'm not able to access the parameters I passed to the webmethod inside of the "OnSucceeded" callback method. I need access to those params because I need to perform more tasks on the client side when the webmethod returns. I'm assuming that the params are returned inside "usercontext", but the value of that param is "null" How can I have access to those params?
Here my sample code:
function OnSucceeded(result, usercontext , methodName) { alert( result + ' The value of usercontext is: ' + usercontext); } function OnFailed(error, userContext, methodName) { alert('Attempt to delete semantic attribute from page failed!'); } function deleteSemanticAttribute() { var username = 'xxxxxx'; var password = 'yyyyyy' PageMethods.GetMyData(username, password, OnSucceeded,OnFailed); } [WebMethod] public static string GetMyData(string username, string password) { return "This is my test application!"; }
Driving me mad on a personal project; I know I've done this before but elsewhere and don't have the code. As far as I can see, I'm setting the parameter, I'm setting its value, the connection is open, yet when I try to fill the dataset I get the error 'Procedure or function expects parameter "@test" which was not supplied'. (This is obviously a simplified test! Same error on this or the real, rather longer code though.)
C#:
SqlCommand l_oCmd; DataSet l_oPage = new DataSet(); l_oCmd = new SqlCommand("usp_test", g_oConn);
vb Code: Function FindCapital(ByVal CountryCode As Integer, ByVal CountryName As String) As StringEnd Function
And later on when i call the function I want the function to be able to show all the available CountryCode and CountryName values, so I can select the one I want. I'm not sure how I can do that or if it's possible.
i have a function which returns a value from a query string parameter, i use it in more than 10 places in the webapp thus i have to rewrite the code every time, again and again.so to make it short, is there any way i can embed the code somewhere and keep referring to it through out my app?
I have a problem in my spilt function. When I pass the parameter, the data is getting splitted by given second parameter and it will return the result as table format. The resultant data is getting truncated. I have to create the dynamic update statement by using this table. Below I have shown the function and parameter.
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript"> </script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
I'm using a CustomValidator control to validate some controls in a GridView. I have the validation working perfectly on the client and the server, but would ideally like to pass the GridView ID into the client function so I can move it out into a separate
.js file. The signature for my client function is:
function valOrder_ClientValidate(source, args) { // Code here}
And my CustomValidator control looks like:
[Code]....
Is there a way I can pass an additional parameter into this function?
