SQL Server :: Filtering Table Contents Shown In DataList
Sep 30, 2010
I am using this code to fill my datalist:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim myConnection As SqlConnection Dim myCommand As SqlDataAdapter
myConnection = New SqlConnection("mydb")
myCommand = New SqlDataAdapter("SELECT * FROM Posts", myConnection)
Dim ds As DataSet = New DataSet() myCommand.Fill(ds)
DataList1.DataSource = ds DataList1.DataBind()
End Sub
It works and fills the datalist with the whole table. When this page opens the address bar is like [URL].Ii would like the datalist to show all contents in the table with this specific thread ID.
I have 2 tables t1 and t2. In t1 I have 4 columns from that I want to insert only 2 columns to another table t2. I only want to send data which is in the form of IP address like (123.123.123.123). After eliminating nulls and other data.
I have a GridView control which contains a custom <pagertemplate> with a <asp:PlaceHolder runat="server" ID="plcPages"> control. The .aspx.cs file contains the following code: protected void Page_Load(object sender, EventArgs e) { ... {Other Code} ... GridViewRow pagerRow = GridView1.BottomPagerRow; PlaceHolder PagePlc = (PlaceHolder)pagerRow.Cells[0].FindControl("plcPages"); Button btnPage; int iPageNum; for (int i = 0; i < GridView1.PageCount; i++) { iPageNum = i + 1; btnPage = new Button(); btnPage.ID = "btnPage" + iPageNum.ToString(); btnPage.CommandName = "Page"; btnPage.CommandArgument = iPageNum.ToString(); btnPage.Text = " " + iPageNum.ToString() + " "; PagePlc.Controls.Add(btnPage); } }
Everything works fine the first time the page is displayed. But, when I click any pager button, including the Next and Prev command buttons that are not part of the PlaceHolder, the contents of the PlaceHolder are never re-displayed. I know from searching other posts that the PlaceHolder contents are lost during the trip to the server, but I am already recreating them every time the page is loaded. They are just never being shown again. I've spent the last two days playing with ViewState And every other combination.
when I hover over a menu option it's contents are shown above instead of the Bottom off. Even though the hover control says bottom. In my browser and others it works fine, I use IE8. But some browsers it's goes wrong.
Let's say I have a table (Table1) with three columns (Col1, Col2, Col3) and two rows. Let's say I have a button on a page. I want to send the contents of those two rows in an email in the Click event handler of the button. Here's the SQL framework I've got: [Code]....
Sql select statement returns: customer_name, month, and count. There is one row per month as follows:
name-1, 01, count1
name-1, 02, count2
name-1, 03, count3
name-2, 01, count4
etc
I want to be able to display as follows:
Customer----Jan-------Feb-------Mar
Name-1______count1____count2____count3
Name-2______count4
etc.
There will be some customer that don't have a month record. The display can show all 12 months.
My questions are: 1) Is datalist or gridview the best? 2) Where can I find examples of how to do this? 3) Also, an example of "no data" for a month. I'm a beginner, have been trying to research, but can't seem to get headed in the right direction.
I have made site with datalist and I want to use SQL data filtering and paging, my only problem is that i want to put filtering into paging procedure paging 1) Alter Procedure dbo.GetProductsPaged
This seems like a stupid, basic question, but I can't find how to do it (plus I've been doing MVC and haven't done in webforms in ages now) - I've got a DataList object that hooks into an SQLDataSource object, and this works fine. However I need to create a second DataList object for a slightly different set of criteria. Rather than creating a second SQLDataSource object and thus calling the DB twice, I would like to make my SQLDataSource object return a broader set of results (this is easy as I am searching on a column, then each DataList is further filtering on another column) and then further filter these results on each respective DataList - how do I do this?
I am trying to do is populate a DataList with the contents of a directory, but not the files in the directory, just that directory's subdirectories. Ideally I would also like that DataList to have links to the the subdirectories that would then show their subs as well (if there are any), but right now I would settle for a static listing.
I've got a DataList showing images from a directory folder and this works well. However, I'd like to be able to page through the results rather than have one long page of images. I was wondering about putting the results in a GridView template somehow and use the paging on that.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim dir As New DirectoryInfo(MapPath("~/GalleryImages/")) Dim file As FileInfo() = dir.GetFiles() Dim list As New ArrayList() For Each file2 As FileInfo In file If file2.Extension = ".png" OrElse file2.Extension = ".jpeg" OrElse file2.Extension = ".jpg" Then list.Add(file2) End If Next DataList1.DataSource = list DataList1.DataBind() End Sub
I want result like below. User Name should be dynamic. May be lot of users. User name will come from Database table.
i want to show details in Gridview(Front End).
Date Bubai Bhanu Total

Total 8 10.30 18.30
I have a doubt and i am sending you the details below, what i want to display in Gridview. below i am describing the sql Table Structure.Original Table Structure.

I have two data tables and I need to compare the dataRows and insert all the unequals into a table. See the codes below. Goal: if the checkbox is true I loop through the ItemData table and store that data into x.Data. Next I look for all records that has row("ItemRandomize") = True and finally I add those records to xData table. There is an if statement in my for loop that checks for duplicate records -- This is were the application fails. How to compare both tables and store the unmatched rows. [Code]....
DBSearchDataContext db = new DBSearchDataContext(); object q = from b in db.Articles where b.Tags.Contains(val) | b.NewsTitle.Contains(val) | b.EnglishContent.Contains(val) select b;
I cannot exclude results where category = video or photos. H to exclude category where value is "videos" or "Photographs"
I want to make a filtering table. It will be a table where below each column it will have a textbox. I want to, while the person type a word in the filter textbox, the table refresh, displaying only the items (rows) with that word. I think AJAX is a good idea. Just put the table and the textbox in a UpdatePanel, and then write a code to refresh the table on textbox_changetext event. The problem is that you have to take the cursor out of textbox to have the event fired, and I want the table update while text typing.
I have a catalog function whereby user can filter their selection by clicking radiobutton. For example, by selecting the Dining radiobutton, all packages related to dining would appear.And i using DataList1.Items. Count method to count the number search result. I had implement this method in the page_load, however the value of the number of datalist keep displaying previously loaded datalist. Here is my code :
I save dates as a string in a varchar data field named "TilDato" in a SQLServer-express table. I want to filter the records smaller than a specific date from a variable in the script. I try the following statement, but it does not seems function logically.
objCmd = new SqlCommand("SELECT * FROM Reservering WHERE @laanedato<=TilDato",myConn2); objCmd.Parameters.Add("@laanedato", laanedato); objRdr = objCmd.ExecuteReader();
I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.
Although I'm a total novice at building web pages, I figured the best way to learn is to do it. I've used a master page and, so far, all the basic information pages work OK.
My problem starts when I have several options for the same Content Holder. Is it possible to use clickable cells to show various *.html files in a different row in the same table.
I can show an image using a script but not a file.
<script type ="text/javascript" > function Change() { document.getElementById ('tdContentItem').innerHTML ='<img src="Images/Thumbs/Councillors.png"/>' } </script>
What I need to show is a clickable imagemap that loads the resulting pages into the same row.
