How can I call onblur event or calculate javascript function in the textbox when I setting values in the textbox in code behind??
<asp:TextBox id="txtQuantity" onblur="calculate(this.id);" Columns="6" Rows="1" TextMode="SingleLine" MaxLength="10" CssClass="xTextBox" runat="server"/>
So I've got a databound grid view within a UpdatePanel.
the user can change the data within the gridview then click a save button to update the data within the database.
However in order to know which rows have been changed I have a textChanged event associated with each textbox, but the event isn't being fired.
Here's the ASP code:
[code]....
<configuration>
<system.net>
<mailSettings>
<smtp
from="user@user.com">
<network
host="smtp.server.com"
password="password"
userName="username" />
</smtp>
</mailSettings>
</system.net>
</configuration>
How can I call the "host"setting from the App.config file in my C# code?
I have tried this but it does not work.
SmtpClient mailClient =
new SmtpClient(ConfigurationManager.AppSettings["network"]);
I have submit button.
How to call this code:
[Code]....
I am calling button click event using javascript
document.getElementById(BtnId).click();
In the same way is it possible to call gridview rowcommand event using javascript.
I would like to set a value:
[code]....
...where [HERE] is the placeholder for my value, from my code behind in ASP.NET before the page is rendered. I generate a guid, and I need that apart of the script on the page.
I have a textbox, on pressing the ENTER key within it, a function should be called with the value in it.
This requires that one of keypress,keydown or keyup to be handled on the server side.
I find that only client side implementation are being followed.
I want to call a function present in code behind from front page (html : source code)
i want to use like this:
Source code
<a href='<%# linkAlpha("B").ToString()) %>' title="B" id="B_List" runat = "server">B</a>
Code Behind
protected string linkAlpha(string value)
{
// /market-research/<%#Eval("customname")%>/
string str = "";
if (Request.Url.DnsSafeHost == "localhost")
{ // /market-reports/<%# Eval("customname")%>/
str = "Alpha_Category.aspx?q=" + value.ToString().Trim();
// Response.Redirect("Alpha_Category.aspx?q=" + value.ToString().Trim());
}
else
{
// str = "/market-reports/" + value.ToString().Trim() + "/";
str = "/Alpha_Category.aspx?q=" + value.ToString().Trim();
}
return str;
}
How can i call a page method after a usercontol finished his method / fire a parent page method from inside the user control insted?

SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString);
SqlCommand command = new SqlCommand("SELECT imagename,ImageID from [Image2] where ImageID='"+s+"' ", connection);.....
now in control i a calling my javscript function from there i need to call my gvImages_selected index change event.
i have a text box with autopostback= true
as in the TextChanged event i have code to get details from database.
i need to check if the text value is empty. if yes need to alert/ display a message and prevent further process.
else fetch the details frm database.
surfed the net and found that onblur and autopostback= true cannot be used for the same textbox.
whts the alternative forr acheving the desired result.
i wrote some code in application start event in global.asax page...
how to call that event in my every .cs page of my project.
I Simply drag a button from the toolbar onto a new page with a master page and a title, double click it so that I enter the Button1_Click function and sets a breakpoint and add some random code. The breakpoint nor the code never fires. I've tried this on several different pages and controllers, but with the same results: The page reloads, but no code is run. I Have Tried:
Ive tried with three different webbrowsers with all plugins disabled. I've tried to turn of Causes Validation, - Nothing changes. I've tried to clean and Rebuild the project, - Still nothing. I've tried to create a whole new project, -Does'nt work there either. Other Information: A RadioButtonList OnDatabound Event works, but whenever i try to do a Button or ImageButton click event the code for the event never fires. Ive programmed several webapplications in other versions of visual studio and ASP.NET but I have never encountered this problem before.
Breakpoints work in other parts of the code and the compile settings is set to DEBUG.
* Visual Studio 2010
* ASP.NET 4
* MVC 2.
Am I supposed to file a bug report or does anyone out there have a solution?
I created a page with several controls (ddl, tbx) that I use for filtering a Gridview. I created a javascript function that runs on the OnClientClick Event of an <asp:button to set the value of an <asp:TextBox to today and a Selected Value in a ddl.
function setMyToday() {
var tbxToday = document.getElementById('ctl00_cntPage_tbxToday');
var tbxUID = document.getElementById('ctl00_cntPage_tbxUserID');
var ddlPV = document.getElementById('ctl00_cntPage_ddlProvider');
tbxToday.value = makeToday();
ddlPV.value = tbxUID.value;
}
The button submits the page and returns some records in a Gridview. I can see the value in the tbxToday when the button is clicked and the row in the drop down list, but when the page is posted,the value in the text bos is lost and as a result is not used to filter the records. However the value in the ddlProvider is maintained.
How we can set image in the textbox in place of text like as watermark textbox in asp.net.
How it can be possible...
i wanna make text box that contain phone number and i wanna tell the client to fill that field in digits.
View 8 RepliesI'm trying to dynamically create a grid view in C#, the grid will have two columns, one of which is a hyperlink field.Now i've noticed when creating the grid view statically in aspx, the DataNavigateUrlFields property accepts a single string as it's value (the field in the data source with the URL in).
When creating it in code, the very same property is a string[] array, rather than a single string, and is expecting multiple fields which combine together to make the URL (if I've understood MSDN correctly), but what if I just want a single field for the URL?
Why does aspx let me do this, but the C# not?
Here's my code:
Name.HeaderText = "Exercise"; Name.DataField = "Name"; Link.HeaderText = "More Info"; Link.DataTextField = "Link"; Link.DataNavigateUrlFields = "Link";
The code above does NOT compile, I got the following error:
Error 2 Cannot implicitly convert type 'string' to 'string[]' This is regarding the last line.
Here is the aspx code, which it's fine with:
<asp:HyperLinkField HeaderText="More Info" DataTextField="Link" DataNavigateUrlFields="Link" target="_blank" />
Does anyone know how I can dynamically create a hypertext field for a grid view, where it only takes a signle field from the data source as the URL?
I am trying to set up my first custom validator in VS 2010 VB. I want it to use a Sub or Function that is in my code-behind. I have searched the WEB but the instructions and examples that I have found do not show me how to use code-behind.
The main problem that I am running into is that I can not find a way to connect the validator to a sub that preforms the validation check.
I need to set the defaulfocus for a webpage that will be used for scanned input.
The page needs to start with focus on a textbox in a formview and remain there as each item is scanned. I have already setup the default button to update data on enter which will happen as each item is scanned. There is only one text box and the update button in the formview.
I have a master page (Site.master) with a navigation menu linked to a datasource (Master.sitemap). I have a nested master page that has another navigation menu. For any item clicked in this nested navigation menu, I want a particular menu item in the Site.master navigation menu to be selected.
Here's my Site.master menu:
[Code]....
In my Site.master.cs I have this:
[Code]....
In the nested master page, Products.master I have this:
[Code]....
In the Products.master.cs file I try to change the selected item.
[Code]....
The master navigation and products navigation menus work just fine by themselves. But when I've tried to set the selected item of the master menu in the Page_Load above, I can't seem to access it. What I've found in trying to do this is the NavigationMenu seems to be uninitialized. The menu Items list is empty. What am I missing here? Why are there no menuItems in the Master.NavigationMenu control?
I would like to be able to set the EmptyDataText property using code-behind. I have created a custom GridView control called PagingGridView. Here is the definition:
public class PagingGridView : GridView {
}
In my ASPX page, I would created a new GridView definition by doing this:
<cc:PagingGridView id="MyGrid" runat="server" ><cc:/PagingGridView>
When I databind the control, I would like my custom control to automatically detect an empty data source and build a table with all the header columns and a row containing the empty data text. The rendered code for the empty data source would be like:
<table>
<tr>
<td>Col1</td><td>Col2</td>
</tr>
<tr>
<td colspan="2">No Records to display</td>
</tr>
</table>
My initial thought was to override the EmptyDataText property but I could not get that to work.
I'm using user controls as web parts in an asp.net application. I have skinned the webparts by adding .PartTitleStyle (etc) to my css. I'd now like to let the user select from a list in an editor part to choose the style for the web part.I'm able to change the title for the webpart, but can't seem to figure out how to change the css to use .PartTitleStyleCustom instead of the default, even trying to set the wp.BackColor seems to have no effect. Here is the code I have so far in the page load event of my user control:
[Code]....

how do you call code behind button click event or a code behind method
from javascript.
I have an asp.net button, that when clicked calls a code behind function. The function does some evaluation, and then I want to call javascript from within this asp.net function.
View 2 RepliesI've googled a bit for the exact order of all gridview events relative to and where inbetween page events. The only Microsoft article: [URL] is not very clear. I'm especially interested in the gridview row_command event relative to page events.
