View 1 Replies View RelatedI have a window form with datagridview,textbox,button and listbox. In datagridview i have added a column. In first row i have given the value like 7000,
second row 2500,
third row 7000,
fourth row 1000,
fifth 1300,
sixth 9000....n number of row:
if i enter 12000 in textbox1 then it will calculate the total in particular rows in datagridview.And the total should be less than 12000 what we have entered the value in textbox1.
The result will display in listbox..
like first greater value is 9000+2500=11500 ,
second greater value 7000+1000+1300=9500,
other third greater value is 7,000.
So i have given a sample code where i cannot get the solution ..
double search;
search = double.Parse(textBox1.Text);

I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
This is what I currently have:
private void txtFilter_TextChanged(object sender, EventArgs e) {
try {
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
[Code] ....
I get an exception error though:
SQLite error
near "'N'": syntax error
// N is what I started typing to start the filter.
Ok, so I've edited the code now to this:
private void txtFilter_TextChanged(object sender, EventArgs e) // FILTER TODO {
DataView view = new DataView();
SQLiteConnection connect = new SQLiteConnection(connString);
connect.Open();
view.RowFilter = "Channel like '%" + txtFilter.Text + "%'";
}
No more exception errors, just not what I want it to do. It just keeps everything there.
I'm trying to add a function now that lets the user open 1 or more files and import them to the database and dataGridView. Now the way it is now (should) work. But when it has finished with FILE1, it won't add FILE2 as it then gives me an error that the Column Date Already exists.

what controls are need in .NET with c#. it will be desktop application,
I am trying to work with C# and i am stuck here. My problem is i want to retrieve the count of all the users in a specific side. Let me Explain. Here is my table snapshot with sample data.
Now what i want exactly is that i get the count of users in a specific side as i give a user id as a parameter.The data is stored in MS Sql Database and i have to implement this on a website so efficiency of code is also a issue.
Suppose i give 1001 as input
The output should be : Left:1 , Right: 8
if 1002 is input
The output should be : Left:5, Right:0
if 1003 is input
The output should be : Left:3, Right:0
if 1004 is input
The output should be : Left:0, Right:0
if 1005 is input
The output should be : Left:1, Right:1
and so on. how to implement this thing. I also want to get a code which would return an array of all child users of a particular ID in a hierarchical manner so that i could process that data with RadOrgChart Control.
