Forms Data Controls :: EmptyDataText Property Ignored When Page Loads For The First
Nov 3, 2010
I've got a dropdownlist and a Gridview Based on the choice from the dropdownlist (which has a '--Select--' as the first item), the gridview is populated. If nothing is in the database when queried, I have a message for the emptydatatext property of the gridview. However, it comes up when the page first loads, since it's based on the ddl. How can I make it so that, when the page loads for the first time, the emptydatatext property is ignored?

Does somebody have a clue about my following issue? I have a gridview with it's datasourceid set to "ods". I have two objectdatasources. One is called "ods" which contains a list with all contracts. The second objectdatasource is called "odsAuthorized" which contains a list with all authorized contracts.
Now i have two linkbuttons "Show All " | "Show Authorized" whith an onClick event where i set the datasourceid of the grid.
When i click the "show authorized" i see a list of all contracts which are authorized. Now when i click on "Show all" is see a list with all contracts. So the onClick events work fine, however. When i change the status in the database so i have 0 authorized contracts, and click on the "Show Authorized" i get to see a label which says "Sorry no records have been found" because i have set the EmptyDataText property on the gridview. Now when i click on Show All, the onclick event for the Show All button never gets fired. I do see that a postback occurres. But i don't come into the event. Does anybody have a logica for this?

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 am working on a site using .aspx controls. Currently I am working on a search feature which searches my database of records and produces all applicable results to the search. Everything works as planned. I have recently added the EmptyDataText line to produce a specific output anytime no results are found in the database. However, I would like to be able to alter/change the appearance of the EmptyDataText output and cannot figure out how to do so. For example, if no results are returned from the search, I would like the EmptyDataText to produce an output of something along the lines of "Your search has produced zero results.
double check your spelling and try your search again." I would like to change the font color, font size, and possibly the thin box which is automatically produced around this output. Is any of this possible? If not, is there another way to produce the desired results? Ultimately, I would actually like to have the results actually use the terms which were input to the search within the EmptyDataText results when no search results are found within my database. For example, if "widget" was used as a search term and "widget" was not found within my database then i would like the results page to state something along the lines of: "Your search for 'widgets' did not return any results. check the spelling and try your search again." Does anyone know how to do any of these things using ASP.Net?

I can't seem to get either EmptyDataTemplate or EmptyDataText of a GridView to work. I'm fetching the GridView contents in de codebehind and attaching them with using DataBind(). I've tried having them as null and as an empty List, and in both cases the text I put intoEmptyDataTemplate or EmptyDataText is not displayed. What am I doing wrong?
EDIT (Code snippet) This is my GridView:
<asp:GridView ID="grid" runat="server" EmptyDataText="EMPTY"></asp:GridView>
And I've tried these two for binding the data:
grid.DataSource = new List<object>();grid.DataBind();grid.DataSource = null;grid.DataBind();

using asp.net/vb.net 2005
In the aspx page I have the EmptyDataText property set
[Code]....
However when no records are not returned I am not seeing the text "No Results Returned" I am populating the gridview using a SqlDataSource. I am not sure why this is happening but thinking about setting the value programmatically, does this make sense and if yes which gridview event should I do this? has anyone else experienced something like this before?

My page includes a button and a GridView bound to a LINQ data object which is bound to a table. when the page loads the gridview gets populated with the data and all work well. The button has an empty method, when I click the button I get en error message "Intenet explorer cannot display the web page" I put a break point at the begining of the method listed below but I get the error message before it gets there. If I remove the gridview than the button works well.

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

My SqlDataSource has no selectCommand defined in the .aspx page. Instead I define it in the code behind dynamically depending on some parameters that the user selects and then clicks a button to perform the query (custom search filters basically). The problem is that when I click on a different page in my dataPager, or I click to sort any of the columns the gridview becomes empty when the page refreshes. I did a check and the selectCommand becomes empty when the page posts back. Is there a way to prevent this from happening?

I have a web page with a GridView and a table outside the gridview to display more information of the record when it is selected (like record details). I'm using data of five tables for this particularly window. I use one table of the five to bind the gridview the other tables are for the details, but I use like 1 or 2 fields of those tables. I'm binding the page with web services. I need some advice on which is the better way for doing this to make a faster web page.
In sql server I made a view with the five tables (all the tables relations are working perfectly). In the web service I call the view; and in the web page I call the web service to bind the page. Everything is working. All I want to do is retrieve from the server all the necessary data only once when the page loads and bind the five tables data (like 18 fields total) in the gridview which I only show 12 fields the other 6 fields are hidden, those 6 are for the details which I get with jQuery (that's another topic). Bind everything only once and manage the data on client side. Everything is working perfectly. Here is my doubt.
How are the maximum table joins I can make? To retrieve the data via web and not get a server time out error. Which is a better way to make a faster page? Make 2 views one for the gridview and one for the details and put each view in a web service; or make one view with all the table joins and one web service. Right now all is working but I have to make other pages that use different tables and joins and I don't know if the server gets me the time out error when the page is fully working.

Here's is my code I just added to my DLL (using it in my website):
[Code]....
Then, in my page_load event, I just have:

I've added a reference to the dll and I've imported it in my page - the only other method (sub) works just fine, but with this, I get an error:Method not found: 'System.String HSIR_Common.Main.StripCurrentUser(System.String)'.

I have a few pages on my website that contain a gridview that gets bound on the page load event. Most of the time while the page is loading, about 5 or 6 rows of the gridview turn into a black box. Usually the box disappears after the page is fully loaded, but sometimes it doesn't and you have to highlight it with the mouse to get rid of it. This happens on more than one computer and I'm not sure how to fix it.

I have a page that calculates some stuff and then displays it to the user. Because the calculation part takes a while I would prefer to have the entire page load with empty data and only after that call the calculation and the display data function.
