How Do Display Total Number Of Rows In A Table Into A Label
Oct 6, 2010
i use sql server 2005 and Visual Studio 2008.
I am using asp.ne and vb.net for my website.
i have a table with number of rows 50,000.
i want to display the number of rows at my table in a Label when the page is on load.
so can u give me the code or the hint?
my second question is.
my table has around 50,000 items.
and i have a search box, it look like this
str= select * from mytable where item='car'
the item Car is located in my table in row number of 45,000.
i guess when i search from the table where the item is car, then it will search row by rows, then as the number of rows become huge, it will be so late to find the result.
so is there any method how to search from table with good speed of searching?
using vs2005 I have a formview control I added from the data section and within the formview, I aded a table from the Standard section. How can I add a text box to the formview so I can enter a number like 7 to display seven rows with a text box. the data will be saved to the sql table when I click on the Insert link at the bottom of the page.
Using C#, how can I check the total number of rows returned from a database when using a Repeater? The reason I need to check is I need to alter the presentation of the data when there is only 1 row returned.
I have a web user control with DataList control in it. In my .aspx page, I have a report header, an empty panel as a place holder, a report footer.In my .aspx.vb file, I'll loop through a list of departments. Within each department, I'll load a label to display the department name and the user control for the data, and add both the label and user control to the panel. So there are two variables: the number of departments and the number of records in a user control.
Now I need to display the current page number and the total page number in the report footer. Is it doable? How? I'm thinking of this approach: declare a page variable count, count the number of department name labels and the number of records in a user control. When the total count reaches a number, such as 20, I'll break the page. This way, I can get the the page current number and the total number of pages. But how to add a page break to an asp.net page?
How could I get the total number of records present in a database table through asp.net in VB? I know about setting up and opening a connection. I wanted to loop through records, so wanted to know the number of records present. How could that be done?
Also, I used statements like 'Update' and 'Insert Into' to to change the data in my data source. Like I updated a certain field like this:
ds.Tables("tblUsers").Rows(2)(3) = "xyzzzz"
and then I executed an sql statement on the same field like this:
objCmd.UpdateCommand = new OleDbCommand objCmd.UpdateCommand.CommandText = "Update tblUsers " & _ "SET City='xyzzzz' WHERE UserID=3" objCmd.UpdateCommand.Connection = Conn objcmd.update(ds,"tblusers") where objcmd is an instance of oledbdataadapter object)
What should I do to delete a record or a field in a data source through asp.net?
I've got this code, I want the amount_01 label to calculate area_01 * rate_01 when values are entered into the TextBox, I've looked and tried everything.
I am having my girdivew as follows.URL....After selecting customer it will be as follows. URL...I would like to display the sum in the label available on the from.This is what I have written to display Amount in the amount textbox
<script type="text/javascript"> function multiplication(txtQuantity, txtRate, txtAmount) { var weight = document.getElementById(txtQuantity).value; var rate = document.getElementById(txtRate).value; document.getElementById(txtAmount).value = weight * rate;
I have a grid view with two columns A and B. Column A has Checkboxes and Column B has numeric values(int). When user checked checkboxes the checked checkboxes column B have to added and displayed in a Label.
I am trying to follow an example from Lesson #25 of [URL] I am not trying to do paging as the above example is doing. I simply want to do a Query and return the the number of rows back in my code behind.
I have a DAL Typed Dataset with the following Query
SELECT COUNT(*) AS Expr1 FROM Reservation WHERE (DateUsed = @DateUsed) AND (SiteID = @SiteID)
I have textbox with search button the result it's show , but if there is a way to count how many rows was found were cathing the data form database. I'm using gridview + ado.net + gridview i handle all the events manually....
I've searched for this several times but have never been able to find the answer with my search terms. Say you have a listview and a datapager set to 10 rows, but you only have 4 data items in the database at the time the query is run. Is there a way to force it to show a 10 row table (4 with data and 6 without)?
Everytime I search on this, I just find information on setting the number of rows for the datapager, which will not show empty rows if the data isn't there. Probably an easy solution, but the heck I can find it.
I HAVE A GRID VIEW IN asp.net + VB Code. There is a drop down list and the selected data is displayed in web page. I placed a label in web page and code behind i used following code.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound Label1.Text = GridView1.Rows.Count.ToString() Dim ONYO As Integer = 0 Dim DONE As Integer = 0 For i As Integer = 0 To GridView1.Rows.Count - 1 If GridView1.Rows(i).Cells(0).Text = "ON YO" Then
I have a form and I want each form to have a unique number when it is filled out so it will go into the database. How can I set this up so when the page loads in the label it will say 1 then the second time it loads it will say 2?
i have one grid which have 5 columns 1 for subject,2,3,4 for marks which have textbox to insert obtained marks,and last column have one lable to display total of (2+3+4),now i want total value on textbox event,when user enter any value to any column of textbox i need to display total of all three columns in total column.
I want to compute the sum of about 10 records in my SQL Server database table, then display that amount in my ASP label. The field is BalanceDue. So, I need the total balance due for all ten records.
I have a aspx page where i have connected to a database using MS Access. I want to display total number of records in the products table & number of records the product Table holds inside.
I am looking for simple asp.net code example showing a simple webform task.
When user clicks a button, a stored procedure fires which runs an update-table query (not pulling any parameters from the user) and returns a count of the number of rows that were updated when the query was run.
Within my stored procedure I have the parameter @RowCount=@@ROWCOUNT.
All sample data I have found online has been C# or VB, but nothing that I can apply to my asp.net program.
Again, this is a simple task that for whatever reason I cannot find examples of online.
in my project i have a gridview gv with 5 rows with check boxes(templatefield).. and 1 label.. my problem is when i check 1st row the row value display in label, if i select 1st row & 2nd row checked the two values display in same label with comma seperation, if i uncheck 2nd row, the row value remove from label and only 1st row will be display..if i select all rows all values are display in label with comma seperation.
