would like to build a chart that will focus on the point plot. which mean every first point index is plotted will show in the chart as more and more chart plotted those point already been plotted will move to the back of the chart so the user only see the latest point is plot in the chart,anyone try this before in mschart ? can we add scrollbar, slide show or something for user to view the past plotted chart ?

In my web forms application I have a site.master page with an update panel (Java Script ToolKit). Inside the update panel I have a survey and a columns chart to show its results. The chart properties are
visible = false
ImageStorageMode = UseImageLocation
RenderType = ImageTag
When the user votes, his/her vote is stored in a sql server table The chart is rebound to its data source
The chart visibility is set to true and the survey's questions are hidden. I've been trying to set the columns for the maximum and minimum values to a different color using the code I found in "Samples Environment for Microsoft Chart Controls" [URL] under Working with Chart Data Data Manipulation Finding Data Points Find Maximum and Minimum Values:
[Code]....
I have not got the columns to change their color. I have put the code inside every event handler I could think of (after it failed to work inside the page load event handler): Inside the chart Init, load, and pre_render handlers. Inside the click event handler for the voting button (before and after I call the chart.DataBind() method). Inside the page pre_render handler. Inside the ToolKitScriptManager pre_render handler. I checked the code behind the environment samples. All, to no avail.
i am using mschart in vs2008 in that i want set our own color for each datapoint using c#. This for the pie chart etc.. and also if there is no data for data point i want point out that field in unique color.
View 3 RepliesThis seems like it should be extremely simple. I have a list of x,y cords in SQL table that I am pulling out into a reader. I am then trying to bind my points to a point (have to use it since I can't find scatter) chart control.
Chart1.Series("Series1").Points.Databind(myReader, "Xpos", "Ypos", "Tooltip=CName")
Where Xpos = the x cord column and Ypos = the y cord column.The chart generates but my problem is that I am getting multiple x values that are the same. For example I have (67, 45) and (67,54).I would think there would be one x value for 67 with the two points on it, at 45 and at 54.Instead I am getting 2 x values listed, both for 67, one with 45 and one with 54.
Just as a test I listed these values in excel (in 2 columns) and did a scatter plot and it generated what I expected (2 items plotted on the same x value, one above the other. Is there a setting I am missing or does the chart control "Point" not have this capability.
I have several gridviews on an aspx and each has a hyperlinkfield. All of them redirect to another page with a single gridview. I am trying to figure out how to get each hyperlinkfield to redirect to the actual point on the receiving page with the corresponding value. In the sample data below, I need to be able to click on 'def' and open aspx page 2 to the point on the page where 'def' is located. All values still need to be visible. Can anchors be used in gridviews?
aspx page 1:
(gridview1)
hyperlinkfield1
field2
field3
abc f2data1

I'm using SqlDataSource and at the point of adding a record, I've called SqlDataSource_UploadNewsLetter_Inserting. In here, I'm testing a value, and if it's true, I need to stop the insert from taking place. But how can I stop the database insert at this point?

View 1 RepliesCurrently I'm designing a web page which will be used for touch screen device. In my gridView it got one button ItemField column so when this button is clicked it will update another column value. So if I got more than 30 records and I want to update the last record I need to scroll down the page to the end and do update. Up to here everything is fine. But the problem is after I have successfully updated the last record; the page will refresh and back to the first record again. So when user wants to view record which they updated they got to scroll down and check. So I just want to know is there any way that allow me to set focus on the updated record. So each time user done update they can straight a way check the result and no need to scroll down.Cos this will be very troublesome for them.
I got think of using Paging, but the page number size is too small ,I don't think it is good to use on touch screen device.
I have created a async search of a gridview, where the displayed data only shows items that match whatever is typed into the text box. After i type the search the grid refreshes the results, but the focus goes away from the textbox itself, which gets really annoying. is there any way to keep the focus on it?

how to focus on grid Row while editing , i mean preserve position after clicking editing or updating
i have gridview of 5000 rows i don t want to scroll up or down after editing or updating, i want to return to the same row to make sure that this row is updating
I have an windows application, in this i have one grid view and am filling the grid view rows dynamically.
Now I would like to focus the last row of the grid while filling in which it is focusing the first row in the grid.
I am trying to set the focus to a control in a gridview (QTY).
<asp:TemplateField HeaderText="Quantity Needed">
<ItemTemplate>
<asp:Label ID="id" Text='<%# Eval("id") %>' runat="server" Visible="false" />
<asp:TextBox Width="30px" MaxLength="4" ID="QTY" runat="server" AutoPostBack="true"
OnTextChanged="check_qty" />
</ItemTemplate>
</asp:TemplateField>
I need to set the focus on the QTY control in the next row in check_qty. I was able to set the focus on the control in the current row by using:
row.FindControl("QTY").Focus()
but I need to set it on QTY in the next row.
I have 4 buttons and 1 FormView.
The FormView has AllowPaging = true.
When you click on a button SQLDataSource1 is bind to the FormView.
So you always have 4 pages.
The data in the FormView has an ID.
When you click Button1 you know you want to see the data with ID=4.
When you click Button2 you know you want to see the data with ID=1.
When you click Button3 you know you want to see the data with ID=2.
When you click Button4 you know you want to see the data with ID=3.
What I want is: when you click on a Button you get the page in the FormView
that corresponds with the ID of the data.
So page 1 isn't ID=1!
What do I have to program to get this working?
I hope someone could clear up my confusion on how this gridview works.
Scenario: We are utilizing edit template within the gridview linked to a validation summary.
Question:How do I give the validation summary focus when a user incorrectly "updates" information within the gridview.
I have tried placing:
Dim reqFldVal As RequiredFieldValidator = CType(grdOrgFullList.Rows(e.RowIndex).FindControl("RequiredFieldValidator1"),
[code]...
Inside the an row updating subroutine with breakpoints but the code is never executed.
I have a gridview placed on the Panel(Scrollbars set to Both).
If I click on Edit button of the gridview for example Row number 100 then the focus of the page goes to the top of page and I always scroll down to the particular record to make changes.
I have a gridview that contains about 35 rows. a user has to scroll down the page to view the rows. when a user click edit. the row goes to edit mode, however, the page goes up to row 1, I need to keep the row visible to the user upon clicking the edit mode. how can I apply such a thing.
View 2 RepliesI noticed that with some of the data controls (like gridview and listview) the page loses focus when you click edit, update, etc. So if your data control is somewhere lower on your page, you'd have to scroll down to get to it again. Is this normal or is there a way to keep the focus or location on where you were previously?
View 2 RepliesI have a Gridview that provides the user the student name for a particular class, a dropdown list to enter grades. If a grade of 'U' is given, a textbox appears in which the last day of attendance must be listed.
It works... though not as conviently as it could; the faculty would like to be able to tab from one dropdownlist to next in succession.
On each ddlGrades changes I write the value to the database and if a 'U' was chosen, display the textBox... but I can't figure how to set focus on the next ddlGrades control, or even the same ddlGrades control that initiated the postbock.

I have a text box in a gridview that is causing some problems with user input. The first time the user opens the page the gridview is populated with zero's in all rows textboxes. I set the focus to the first textbox in the Page_Load event but the cursor is placed to the left of the zero and when some users enter data they don't realize the zero doesn't go away so the first row ends up wrong. Once the tab or enter key is hit and the next row is selected, the zero is "selected", for lack of a better term like when the insert key is predded, and once the user starts typing only the new value remains. Is there a way to make the zero in the first row "selected" ?
View 1 RepliesI have a GridView that has approximately 800 records. I have a search feature that finds a record and focuses to it. When I click Edit for that record, the Gridview flashes and goes back to the 1st row. If I search for the record again it is in edit mode. Is there some setting to keep focus where it is? I added the following code to try and keep focus, but it doesn't work.

I have a gridview with edit functionality and using the EditItemTemplate section. I am trying to set focus to a textbox when user selects the edit mode.
[Code].....
Asp.NET v2.0
Data grid with mulitple texboxes per row.
Each textbox has a TextChange() event wired up for data validation.
These events fire just fine, the data validation works just fine.
My issue is this: User enters text into TextBox1 one then tabs into TextBox2. The cursor appears for a split second inside of TextBox2 then disappears as focus is being set somewhere else on the page. I'm not sure how that change of focus is happening.
In this scenario, after tabbing out of TextBox1, how can I maintain focus on TextBox2 (and then subsequently TextBox3, TextBox4,etc..)
