grid view without any data source date sorting problem

In ASP.NET 1.X and ASP.NET 2.0 DataList was the primary control used to display data in groups. In ASP.NET 3.5 we have a new control that takes care of grouping data. In this article we are going to demonstrate how to group data using the ListView control.

Many times you want to select multiple columns in a DataGrid and highlight the columns selected.

In the DataGrid MouseDown Event you will find out if you have selected a column header through the hit test. You then find the co-ordinate of the column and construct a rectangle out of that. If you are selecting multiple columns you can store the index of the columns and the rectangle in ArrayList.

Make sure you clear the ArrayList when you HitType is None.

Hi,

I would want to know what is better: to keep a lot of data in cache at once or to keep a little data by paging?

 

For example:

I have 1000 articles and 200 pages.

 Hi, I have window form to let user fill data, I want to alert user if close web browser before saved web form data, could anyone provide any clue?

 

Thanks,

Martin

I've got a Imagebutton in a repeater.
Code:

<asp:Repeater ID="repImages"  runat="server">
                    <ItemTemplate>                       
                        <div>
                            <div><asp:ImageButton ID="btnDeleteImage" Width="7" Height="7" runat="server" AlternateText="Verwijder afbeelding"  OnClientClick="return confirm('Weet u zeker dat u deze afbeelding wil verwijderen?');" OnClick="ImageButton_OnClick" ImageUrl="~/images/spacer.gif" /></div>
                            <img id="imgImage" runat="server" src='<%# GetOccasionPath(int.Parse(Eval("ID").ToString()),Eval("BaseFileName").ToString(), TypeImage.thumbnail) %>' />
                        </div>
                    </ItemTemplate>
                </asp:Repeater> 

 

It is displayed well, but if i press the button btnDeleteImage he doesn't even run ImageButton_OnClick , also there is no data included just for testing...
protected void ImageButton_OnClick(object source, EventArgs e)
    {
       
    }

 

But still i get this error:

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> 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.

Also enableEventValidation="true" is placed in the page.
What can i do to solve this?

Hi all,

I have a SQL routine which builds me an entire XML file and returns it as a string. 
If I save the content of this file as sample.xml for instance, I am able to open it in IE or any other browser and the user can expand the nodes and see all the content he wishes.

I am trying to build a ASP.Net page which will display the content of a XML file in the same way (or similar) that the browsers do.

So far, I've been reading some posts and noticed I can use XmlDataSource control and its Data property to load the entire XML doc as a string. Now I am stuck how to display the contents. I found TreeView very confusing and not sure if DataGrid would be a alternative as well. I need to user to be able to open and expand the nodes.

Please someone point me to the right direction. What controls to use, etc... sample codes are the best ;-)

Thank you

 

HI

My project upgrade to MVC3 R2, but there is a problem with validation metadata when the model inherit from other class.  In MVC2 all the child class will inherit the validation metadata, but in MVC3 R2, it will be not include the validation metadata of parent class. Is this expected?

Hello

I am using Visual SVN Server and Tortoise SVN as a Client. 

After I get update and ascx file is merged visual sdutio displays warning and I must set merged file line encoding.

The line endings in the following file are not consistent. Do you want to normalize line endings?

I believe that it's due to default SVN merge tool or visual svn behaviour for currently opened files.
