Dear All,
I am using a gridview in my asp.net application which is having an edit Item template as well as an Item template. Each of the template is having about 50 controls in which three are combo boxes which are populated from sqldatasource. I use this gridview for edit update delete operations.
My problem is that , when I am having about 10 rows my gridview is almost freezing when doing edit update operations. I commented all the source codes thet I have in code behind class, but no use. Do the rendering take this much time ? Can anyone please give me some tips for speeding up my operations. I need to use this type of gridview in many places in my application. Please help..
Thanks in advance

Hii
Thanx for the reply.
The gridview is associated with an sqldatasource. As per your reply, is it making the gridview slow ??

OK.. thanks I will try that way..
And also I found another thing.
I am showing the gridview in a div with scroll bars. When I turned the paging option on in gridview ,it helped the situation very much and I found the operations being faster. 
Anyways thank you very much for your precious opinion ..

I have an application that retreives records from a database, which will be displayed in a datagridview. Moreover, I would also generate a csv file from that query and allow user to save it. I have a code that save a csv file but I don`t have a code on how to generate a csv from database records. How will I do that? Is any body here who can help me. Much appreciated if somebody will give me a link or code.

Hi,
I developed one user control which contain 3 check boxes. Now Checkbox3 is enabled only Checkbo1 and 2 are checked. I want to enable the Checkbox3 by using the JavaScript by checking whether checkbo1 and 2 checked or not.
Can anyone help me on this.
Thanks in advance

This is javascrpt 101, the main thing is you need to write script that creates variables that contain the client side names of the checkboxes.
What else do you need help with ?

Read "How to get an answer to your question"

You probably would have to modify connection string, to point it to mdb file.

Hi,
I have an array like this:
string[3] arr;
arr[0]="ck1";
arr[1]="ck2";, arr[2]= "ck3"..
Now In my aspx page I have 3 checkboxes. Now I want to set the Checkbox text from the array arr values (for the first checbox text as arr[0]. like this) instead of setting the text while declaring the checkboxes.
Thanks in advance.
|
|
|
|
|
there is a read/write property "Text" for checkbox. So what is the problem is setting the text ?
You can set it like
checkbox1.Text = arr[0].ToString()

I can't seem to get to display the results from a gridview. The code compiles but it only shows 'no records' when I display the webpage. Any help would be greatly appreciated. I am thinking that maybe the information for 'typename' and 'dataojecttypename' are incorrect. What exactly should these two contain?
Here is my code in part:
[DataObjectMethod(DataObjectMethodType.Select)]
public static List<userdata> getAllUsers()
{
MySqlCommand cmd = new MySqlCommand();
DB_Connection conn = new DB_Connection();
try
{
cmd.Connection = (MySqlConnection)conn.DBConnect();
cmd.CommandText = "getAllUsers";
cmd.CommandType = CommandType.StoredProcedure;
cmd.ExecuteNonQuery();
MySqlDataReader dr;
dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
List<userdata> userList = new List<userdata>();
while (dr.Read())
{
UserData user = new UserData();
user.UserID = Convert.ToString(dr["User_ID"]);
user.UserLastName = Convert.ToString(dr["User_Last_Name"]);
user.UserFirstName = Convert.ToString(dr["User_First_Name"]);
}
dr.Close();
return userList;
<asp:objectdatasource id="ObData" runat="server" typename="users"
="" oldvaluesparameterformatstring="original_{0}" selectmethod="getAllUsers" dataobjecttypename="userdata">
<asp:gridview id="GridView1" action="databind" runat="server" datasourceid="ObData" autogeneratecolumns="False" emptydatatext="<b>No Records</b>" allowpaging="True" datekeynames="User_Id">
<columns><asp:boundfield datafield="User_Id" headertext="User_Id" sortexpression="User_Id">
<asp:boundfield datafield="User_Last_Name" headertext="LastName" sortexpression="User_Last_Name">
<asp:boundfield datafield="User_First_Name" headertext="FirstName" sortexpression="User_First_Name">
|

Your method returns userList, which has only been instantiated and has not been initialized. You might want to put some values in that list for the datagrid to bind to. I'm assuming thats what you're binding the datagrid with.
Next time, please put the code in <pre></pre> tags to make it easier to read.
