ADO.NET :: Displaying A Range Of Data In Detailsview?
Nov 29, 2010
I am persevering with visual developer express 2010 whilst learning visual basic from hello world stage onward. In the meantime I have a difficulty . I am trying to display a range of data in details view which is being fed a parameter from a dropdown list. I cannot seem to come up with a query that will pull over all data from a column that is less than a certain number and then display it with distinct values in the dropdown. for example I would like say to pull over height data where it displays all data below 20m all data below 30m etc. is this possible without heavy coding?
Issue: Data not displaying in DetailsView web form control. (Details view control doesn't display at all although it's Visible and Enabled properties are set to True.) Other things such as textbox and hyperlinks do display on the page.
I'm feeding a QueryString from a user defined(hyperlink) column in a DataGrid located on the parent(list) aspx page.
The DetailsView aspx page has an object data source pointing to a table adapter that has a query defined that is expecting a parameter of type INT. The parameter source is coming from Request.Querystring. As noted above, the DetailsView control is not displaying when the page is loaded. I've alternately fed the ID from Request.QueryString to display in a textbox on the page; the ID parameter is present and displaying in the text box.
IF the ID Integer needed by the DetailsView's ObjectDataSource is making it to the page and if the ObjectDataSource is working(I can test preview data) I'm wondering why the Details view is not displaying, and displaying with data.
How can I display edit and new buttons without duplication in a detailsview control? This is a question from a past exam paper for 70-562. Part of the question is below:
"The company CIO assigns a task to you. According to his requirement, you must make sure that the users can insert and update content in the DetailsView1 control. Besides this, you have to prevent duplication of the link button controls for the Edit and New operations. At line 3, which code segment should be inserted?"
I have a dropdownlist bound to a table and the selection filters the detailsview. After a new record is inserted using the detailsview, the new record is displayed in the detailsview and the initial record is displayed in the dropdownlist. After the insert, how can I get the dropdownlist to display the new record?
I have a Range Validator as follows. It is for restricting values between 1900 and 2070. However, it fires error when I enter a alphabet also. I want this to be fired only if the user enters integer values. How do I overcome it?
When using a range validator, if the user exceeds the defined range, How do you code it so it disables a button so the user can't continue. (without using JavaScript)
I have a table "RANGES" with the following columns
LowRange as int HighRange as int with the data similar to below select * from Ranges LowRange HighRange 1 100 101 200 201 300 . . . 901 1000
And another table "infoDetails" with the following columns
Range as INT amount as money with the data similar to below select * from infoDetails Range Amount 23 34.00 235 44.00 345 34.00 678 100.00 555 100.00 530 100.00 510 100.00 I need one report with the following format without cursor. LowRange HighRange Count Amount 1 100 1 34.00 101 200 0 0.00 . . 501 600 3 300.00 601 700 1 100.00
I want to validate textbox, so user enter greater than 30
if user enter lessthan 30 than message will display.. for that i use range validator of asp.net
<asp:TextBox ID="txtprice" runat="server" CssClass="textbox" Width="180px"></asp:TextBox> <asp:RangeValidator runat="server" Display="None" ID="range1" ValidationGroup="grdsave" SetFocusOnError="true" ControlToValidate="txtPrice" MinimumValue="30" MaximumValue="999" ErrorMessage="Minimun budget is 30 USA dollor"></asp:RangeValidator> Â It give message if i enter less than 30. but if i enter 100 or 200 it also give message. How can i allow that value?
I am trying to arrange the information from a SQL record into a 3 column by 3 row table to fit the form presentation that I want. I have placed on the page 3X3 table and then tried to place a detailsview in the first cell for the first picture called P1dv.
I have place a detailsview in the last cell that would control the paging of information called Controldv. I need to fiqure out how to link P1dv paging to Controldv page action. I am using visual web dev. 2005. I am not updating or editing these are read only views.
example of what i need the form output to look like:
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
I has developed a crystal report, which display the records from a table and filters them based on a parameter( date range parameter). now I has integrated the report into a asp.net page using c#, but when I am running the asp page it is not promption for the date range values, it used to prompt for date range when I run the report in crystal report.
I have data from multiple tables that I would like to display in a gridview via a stored procedure. I need to select the data based on a date range and display it. Once displayed I need to include a button that would allow the user to export the gridview data to an excel spreadsheet. Does anyone have an out of the box solution or know of a tutorial I can use to accomplish this feat? I am currently using 2.0 for this project. I am newish to .net.
Here is my stored procedure that calls the data from multiple tables.
I have used to code below successfully to export a gridview to an excel spreadsheet, however when i use it for a gridview with data from a different table i receive the following error:
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
The thing is it works locally fine but when i upload to my shared server i receive the error above?
I have read and referred your range slider and loading infinite images on scroll.The issue is when combining both the article the data is appending to old one.
I need to create a report that will show the list of data that is within that range of period. The scenario will be:
- the user will choose the starting month and the ending month from a drop down list. (for example, starting month = July and ending month = September)
- then the report will be showing all the data within that range of month chosen by the user. (data from July until September will be shown, including data from the month of AUGUST)
- the problem I'm having is that when I choose the starting month and ending month as shown above, I only get the data from the month of JULY and the month of SEPTEMBER, the data from month of AUGUST will not be shown.
I am working on website where i am getting error when try to insert data into database from my asp.net website
The Error says that :
" System.Data.SqlClient.SqlException :
The conversion of a varchar data type to a datetime data type resulted in   an out-of-range value."
using System; using System.Collections; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls;
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
it is a simple question, but i didn't understand. here is the code below:
Private Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated Dim drv As DataRowView If e.Row.RowType = DataControlRowType.DataRow Then For i As Integer = 0 To e.Row().Cells.Count If " ".Equals(e.Row().Cells(i).Text) Then e.Row().Cells(i).Text = "" End If Next End If End Sub
the line "If e.Row.RowType = DataControlRowType.DataRow Then" occured exception below System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection
I am getting error Specified index out of range of valid values. Parameter name index. I tried to put a breakpoint and see where am I getting the error. I have 5 columns (1 hidden). first 3 columns- no issue. But when the control reaches the 4th column it throws the error. I saw that I am getting correct values for the first 3..no ide what is going wrong with the 4th one.
I have a DetialsView that has a year field that needs to have the range set dynamiclly
I use this when it was just a textbox outisde the detailsview
protected void Page_Load(object sender, EventArgs e) { rvYear.MaximumValue = Convert.ToString(DateTime.Today.Year); rvYear.ErrorMessage = "Must enter a year between 1900 and " + Convert.ToString(DateTime.Today.Year); }
I recently had to remove a field from my datakey on all three gridview tables. On the top level table the field (ignum) remains as a non key field. On the two lower level tables it was removed completely. Now, the top level gridview opens correctly, but when I click on select this should bring up all the records in the second gridview associated with the selected row in the first gridview, but I get the following error:
[Code]....
I've looked at everything I can thing of and everything looks ok. The tables look good, I've removed all references to the removed field and I've restructured all the code to account for the changes. I'm missing something, but I don't know what. I've gone through debug step by step and the error occurs as I leave the GridView1_SelectedIndexChanged code. It goes down to the End Sub line with no errors, but when I step again it errors out. Here is that section of code.
I have a ListView InsertItemTemplate where there is field (Date) using the AJAX Library CalendarExtender. I want to add some validation to this field, whereby they can't add a date that is later than today. So I have added a RangeValidator and tried to set its MaximumValue to DateTime.Now on Page Load. Unfortuantely it isn't working.
