Hi all,In my asp.net application i'm using gridview to which i'm binding data dynamically by writing a select query in code behined file (all column's are autogenerated) now i want to change gridview cell to edit mode from label to textbox or dropdown on clicking of gridview's cell.How can i achive this in code behined file.thanks in advanceraj
I got stuck in the following problem.
I am using cascadingdropdown ajax control and binding data into dropdownlist from database.
I have done to display the data from database.
Now I want to display the data, which is related to the item which I selected from dropdownlist, to 'Label'.
ex) I have a following table in database.If I select '2' from the dropdownlist, I want to display 'Taro' to the label. If '1' from the dropdownlist, 'Ken' to the label.
I changed 'AutoPostback' property of dropdownlist to TRUE,then when I run the page and select the item from dropdownlist, error occured.
Error messege is as belows.
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using in configuration or in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
If there is another way to display the item into a label without postback, or someone knows how to sort out this problem, please help me.
Hello All,I am facing a weird issue.I have a label on the front end but when I try to use it on the code-behind and run my code I obtain an error: Label does not exist in the current context! The label is shown in intellisense and was working earlier.My team mate had created a back up of the file and it stopped working after that.I deleted the back up files and tried but it doesn't seem to work.Any suggestions will be greatly appreciated.
The following is the code snippet of the front end as well as the code behind:
<img src="sunny.jpg" alt="sunny" height="40px" width="40px"/>
<p><i>(5 minute Averages)</i></p>
<td><b><font size="2px">Current Time</font></b></td>
<td><asp:Label runat="server" ID="Label_Time"></asp:Label></td>
<tr><td><b><font size="2px">Temperature</font></b></td><td><asp:Label runat="server" ID="Label_Temperature"></asp:Label></td>
I have an SP that simply performs a COUNT(*) from a table. I'm am trying to print that number in an ASP Label. It works in Query analyzer but I cant wrap my head around how to display it in a label. Any guidance much appreciated.
I'm using the following msdn article to use different languages in my web application:
I'm following the instructions step by step in VS 2010, and it creates the resource files exactly how it's supposed to.
However, when I run the program it just doesn't apply it. I don't see the different values from the resource file. If I leave my resource file name as sample.aspx.resx, it works. But when I change it to sample.aspx.en-us.resx, it doesn't work. I'm supplying culture from the aspx page's Culter and UICulture properties. I'm being very careful in choosing the correct file name, as that could be the issue, but it just doesn't work. I also tried changing the culture in the backend code this way:
I am not able to change the direction of popups/Alerts in Arabic culture which should be RTL direction.
Rest of my application is changed in above culture, only problem is with popups and alerts.
Thanks in advance.
I've been handed an application thats connection string implies a local host connection.
I want to make this connection a remote connection, to a database located on a Server. I want the client and server to be able to communicate with one another remotely, instead of a local connection.
How does one create the Data Service, and establish end points to Server and Client? Is it as simple as creating a contract (which I have limited knowledge on constructing), between the two locations, setting up the dataservice, security, and ratifying the 'connetions'?
A smidge of insight, please ;-)
Sorry for a basic post here; I am very new to VB!
I am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:
(e.g.) "24 results found for 'blue sky clouds' "
...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.
If no results are found I would like the label to display:
(e.g.) "No results were found that match your selection. Please try again"
I would also like the label to be invisible until a search occurs.
Thanks in advance!
I have been using asp.net menu control that is programmatically binded at runtime and has n child node levels. Now i want to use CssAdapterMenu instead because the menu control contains more than 1000 menuItems(in the near future it can also be more 2000 menuItems) and has very slow response in IE 6 or IE 7.
Now my question is how should i change the classic asp.net menu to CssAdapterMenu. What should be the steps? Any samples example of n child node levels would be helpful

Great ideas are timeless. A long time ago in Microsoft Systems Journal Paul DiLascia demonstrated a neat trick to display context-sensitive tooltips floating over pictures. As the user moved the mouse over the picture, the tooltip control updated its text to reflect the name of the pointed figure.

Although the context menu is a common element of most desktop applications, it is still fairly uncommon in Web application names because it doesn't map well to a server-based technology like ASP. NET.
