hi there, i tried out and it does display the info in the grid view. however, when a new file is uploaded, the existing info in the gridview is being overwrite by the new one. Any idea how to not let it overwrite the previous data? thanks!

This is why, I guess you didnt check the IsPostback Property on Page_Load().
So when the Image is uploading, Page is getting postback and grid is binding with blank data.
Do something like this is Page_Load
if( ! Page.ISPostBack)
{
BindGrid();
}

I want to bind not all but one part of columns of a datasource to a gridview, but I do not know which function can be used?
for example, the following code is used to bind all columns of database "Departments" to gridview departmentsGrid.
departmentsGrid.DataSource = dataSet.Tables["Departments"].DefaultView;
departmentsGrid.DataBind();
Note that for the gridview, I have set "AutoGenerateColumns" as True.
therefore, I have to select all the columns to bind. perhaps, I can set "AutoGenerateColumns" as False and then bind the columns one by one?
or is there any better solution?
thank you!

You have to do it on RowDataBound Event of Gridview.
|
|
|
|
|
It is always better to specify columns on the designer and AutoGenerateColumns false. So that if the selection to departments changes the page becomes intact.

I want to bind the gridview to a datasource which contains one image field. I have the following questions:
1: I use SQL 2005, it seems to be there are one 'image' type and one 'varbinary(max)', which one should be used?
2: in order to bind the imagefield to the gridview, i have to add one imagefield in the gridview, because gridview can not automatically to bind it.
but I use the following code, the image can not be displayed, instead of a red cross:
<asp:ImageField HeaderText="image" NullDisplayText="no"
NullImageUrl="~/Images/book_closed.gif" DataImageURLField="ImageTest">
</asp:ImageField>
<asp:sqldatasource id="DepartmentsSource"
selectcommand="Select [DepartmentID], [DepartmentID], [ImageTest],[Tel] From [Departments]"
connectionstring="Server=localhost\SqlExpress;Database=Dorknozzle;Integrated Security=True" providerName="System.Data.SqlClient"
runat="server"/>
anyone can give me one hint why?
thank you!

You want to add records from gridview ?
Have a look into it.
Adding an insert row to GridView[^]
Or you want something different ?

I'm busy getting to grips with my first Dynamic Data project, using LINQ to Entities. It's going quite well so far, but on my Employees edit form, when I click the 'Update' link, it calls back to the Edit.aspx page, but nothing else happens. No SQL is sent, and no error is raised. I have had this problem before with a SqlDataSource simply swallowing exceptions, but I've been led to believe that the object based DataSource components are better behaved.
I have no idea where to begin looking, because the Edit.aspx has no explicit update code in it, so I have this dark cloud between it and my DB where something is happening to my update, which is anybody's guess.

why dont you debug the application and see what error is occurring. Have you seen SQL profiler as if there is any entry of update statement being generated and the error is generated in SQL server or not?
|
|
|
|
|
There is nothing to debug. My break point in the Updating event hits, but not the updated event. No SQL is sent through. I've discovered that something, probably EF, doesn't like self-referencing tables, e.g. the Employees table has a one-to-many relationship with itself, because the Supervisor field points back to an EmployeeID.

Why do you want to show javascript alert ?
If user is not authenticated properly show a nice message in Red color just below the Login box like "Username/Password is incorrect. Please relogin" as every site does.
You may have Forgot Password link as well.

This can be done by following ways,
GridView1.Columns[0].Visible = false;
or Set the Width=0 for that column.
Hope this will help you
