Forms Data Controls :: Summing Records In Table?

Jul 6, 2010

In my table of entries, there are other entries commenting on the orig entry. The comment entries are marked in the table by having a commentID field that matches the ID field of the post being commented on. Follow?

How would I sum the nbr of comments for each orig entry?

I want it displayed in upper superscript fashion like the "2" in E=MC "2"

Mar 28, 2011

I can't get the total from the row of the grid as I enter in the cells of the first row. Doesn't SelectedIndexChanged fire asI leave each cell?

I set a break point in the code and it's not stopping there.

<asp:GridView ID="GrdDynamic" runat="server" AutoGenerateColumns="False"
onrowdatabound="GrdDynamic_RowDataBound"
onrowediting="GrdDynamic_RowEditing"
onselectedindexchanged="GrdDynamic_SelectedIndexChanged" SelectedIndex="1"
AutoPostBack="True">
</asp:GridView>
protected void GrdDynamic_SelectedIndexChanged(object sender, EventArgs e)
{
double total = 0;
for (int colIndex = 0; colIndex < 16; colIndex++)
{
if (GrdDynamic.Rows[0].Cells[colIndex].Text != "")
total += Convert.ToDouble(GrdDynamic.Rows[0].Cells[colIndex].Text);
}
GrdDynamic.Rows[0].Cells[16].Text = total.ToString();
}

Forms Data Controls :: Databind Refresh - Records Left In The Table And goes To The <emptytemplate> ?

Feb 9, 2010

I have a gridview, and I set the datasource in page_load to a linq query. I have delete linkbutton in the grid and am writing code in gridview1_rowdeleting event to delete the record from the table and all its records in child tables. Works fine, except when I databind() after the deletes to refresh the grid, it thinks there are no records left in the table and goes to the <emptytemplate> . There are in fact many other records that should appear. When I go out of the gridview and come back in, everything is fine. The proper records have all been deleted, and the remaining ones show. Here is the code. the table being displayed is Schedule. It has child records in the two other tables.

[Code]....

This is from Page_Load

SQL Server :: Adding A Bunch Of New Records To The English Table / Repeating The Data Entry Into The Spanish Table

Oct 29, 2010

I have two tables for storing language translations - tblEN and tblES. They have the same structure which is nvcEnglish and nvcLocal - both nVarChar fields.

In nvcLocal of the Spanish table, I enter the Spanish translations of words and phrases used within my app. Problem is, when I add a bunch of new records to the English table I also have to go in and repeat the data entry into the Spanish table. I am wondering if there is a way to import the newly added records into the Spanish table using Transact SQL?The plain language query would be something like:

If the data in tblEN.nvcEnglish does not exist in tblES.nvcEnglish then insert a new row into tblES with the values from tblEN

DataSource Controls :: Summing Multiple Columns With SQL?

Mar 9, 2010

is there a SQL statment i could write that would sum each column and allow me to then access each sum individually

i.e

Dim objCmd As New OleDb.OleDbCommand("SELECT SUM(expression) FROM orderForm WHERE OrderDate=@OrderDate", objConn)

is there anything i can replace expression with such that all the columns in orderForm could be summed and returned as one record

or is there a way to replace expression with something that would allow me to just keep changing the paramater so i could continuously reexectute the same command w/o having to create a new command for each column

DataSource Controls :: Loop Through The Records Of A Table?

Mar 19, 2010

im learning t-sql, infact i needed its while-loop to loop through records of a table, i found this code in some book:

[Code]....

i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?

if the underlined select statement returns one record everytime it is executed, isn't it supposed to return the same first record of the table everytime? is there a better way to loop through a table's records?
