Have Tried To Reproduce The Drilldown Datagrid Searching?
Mar 24, 2010
I have tried to reproduce the drilldown datagrid searching in asp.net in Visual Studio 9 using MS.Net 3.5 and I'm running into problems. I copied the code from the site but I'm getting an error that says "name MyDataGrid is not declared" I get the same error for subsrch, msg, count and all other text boxes. I tried to recreate the datagrid and text boxes by using the VS tools and renaming them but that didn't work either. I still got the same errors with the new names. Any idea why this would happen?
am using asp.net 2.0 + c# .i want search like if we click letter A, all the entries starting with A should list on a grid ,like that for B ,C upto Z.how can i do it.Is there any control for displaying all 26 lettersor should i give hyperlink or link.
I'm working on an ASP.NET 3.5 project that requires me to create several custom navigation server-side controls that can be customized at design time by non-ASP.NET website developers through a simple text editor. All but one were relatively easy to create, but the last one is stumping me. I've looked online and can't find any examples anyplace that come close to what I'm trying to do.The last control needs to give the site developers the ability to manually define the number of nodes that are displayed within the control when it's rendered on a page, and I want to reproduce the design time/runtime functionality of the GridView's "Columns" property. In the Columns collection the site developer at design time can manually specify the look/feel of each column within the ASPX designer. I want to give my site developers the same design-time flexibility so they can add/remove nodes at their whim and not bug me to do it for them. an anyone point me to any examples of how to create a collection custom child controls that are associated with a custom server side control?
I want to create a drilldown sub report such that when one clicks on the column in the main report, it should expand to show the data corresponding to clicked column in subreport. For Ex -
MainReport
[code]....
Now if user clicks on 'Main Id' value in MainReport, it should expand to show the sub report data coressponding to the Main Id value.
I'm using VS2005 / VS2008 and MSSQL RS 2005 + ReportViewer v.8 or v.9.
Problem: when user makes drillthrough click on "plus sign" on Matrix row postback occurs. Then scroll position is lost! It scrolls to the top of the page. It's very bad for report users.
The most interesting thing is that it happens only within ReportViewer! I works acceptable if I open report via "localhost/ReportServer/Pages/ReportViewer.aspx?..." . It's based on something similar to ReportViewer :
[code]....
And it remains scroll position well!
Is there a way to make ReportViewer working correcly? (remembering scroll position on Matrix row drillthrough postback)
I read that Report Viewer 10 (of VS 2010) will lack this issue but it doesn't support MSSQL 2005 which I plan to use so far.
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.
I have Datagrid , i want to clcik on row and get data in textbox , but my textbox is FreeTextBox control,i tried to use javascript but work for asp.net control not working for freetext box control, how i can capture this code is sample code but it work for asp.net control but not working for my freetextbox
Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
I have 2 datagrid (using .net 1.1). I need to access column of second grid ( i need to make a column of second grid as disabled) when i click "Cancel" link button in First Grid. How can this be done?
I wrote a console app that displays information from a local file on my desktop and displays the content within the file. I was wondering how can I create a function that can search for keywords and only display the words, I want it to search for?I'm trying to display this content in a database and search for the content I want it to display.
* ZIP Codes * Area Codes * City Name * State Name * Two digit State Code * City Type * City Alias Abbrev. * County Name * State FIPS * County FIPS * Time Zone * Daylight Savings Indicator * Number of Businesses * Q1 Payroll * Annual Payroll * Number of Employees * Employment Flag * County Growth Rate
I tried something like this - And it didn't work.
Csharp Code: var keywords = new string[] {"some", "keywords"}; var foundKeywords = File.ReadAllLines("filename"). SelectMany(line => keywords.Where(keyword => line.Contains(keyword))). Distinct();
I have a web application running on ASP.NET 3.5 which basically stores, retrieves, and allows users to manipulate data from a SQL Server 2005 database. One of the features allows users to search through the records in the database. When the system was first launched last year, there were no records, so searches were lightning fast. However, over the past year, about 100,000 records have been entered, so most searches now take over 15 seconds to perform. I'd like to speed up searches, but there are problems with both of the conventional approaches I can think of:
Caching - The database does all the heavy lifting in this application - the ASP.NET web application is little more than a UI that passes user input to the correct stored procedure, and displays the returned output. The stored procedures are responsible for interpreting user input, applying the business rules, and transforming the underlying tables and views into a context-sensitive result set which the application just displays as is. Unless if there's a way to apply a stored procedure to a C# object/collection (the cached records), and get another C# object/collection back, effectively bypassing the database, I don't think this will work.Stored procedure optimization - There's some optimization potential here, but even a simple SELECT * FROM TheView statement on the underlying view currently takes 11 seconds according to SSMS, and I expect that the amount of time taken will continue to increase as more records are entered.Are there are techniques out there that I'm not aware of, which could be used to bring searching down to a reasonable amount of time (5 seconds or less per search)?
First off I'm a week into asp so apologies in advance for silly questions! I am looking to connect to a SQL database table and allow the user to filter the table based on a search box on the asp page. I have written a sql query with a parameter in the where clause, a bit like this:
select col1, col2 from table where col1 like @my_parameter
Then I pointed the parameter to a textbox on my asp page, and this seems to work quite well. However, I would now like to add an additional search facility which would be a dropdown list. This would be sourcing all the unique values from the col2 in my table abve (there are only about 10 possible values here). But I don't want users to be able to use both of these searches at the same time.
So the bottom line is I would like to offer two methods of filtering the same data table, which search on different columns of the data table. Then the results should populate the same results table, but the user must only be able to use one search method or the other.
I have done a bit of research but couldn't find anything along these lines (I think it is becuase I don't know the words of the things I should be searching for!). I did find information on a standard postback event or cross page posting - not sure which of these (if any) is the best to use for a beginner?
I have a webform that uses a gridview to display a list of records from a table. I also have a search box that allows the users to input their search text and next to it a Find button which will take whatever that is in the search box and match it against each record in the datbase using a simple select query.
Whenever this search is executed it takes up to 20 seconds to display the returned result in the grid. The search query uses the SQl Data connector class through SQL ADO.NET.
However, when I perform the same query in the SQL management studio the search takes a total of 2 seconds. I'm wondering why there is a big difference in timing. I know that the query searches the table of about 4,000 records. I read up on paging but I am new to this concept.
I am having a little trouble in working out the best way in which to query my database. What i am looking to do is to search a using a textbox, the problem is that there is not only one field or one table I want to search for. For instance I have a table of parts that contains the part number, part name, the associated project number, searching for these would be relatively straight forward, I also want to be able to search based on the project name (this is stored in a seperate table) I have thought about using a drop box to allow the user to specify which column they want to search in however this didnt work very well. Ideally i will be able to add more search functions onto this after.
I have a couple tables that are kind of unrelated - id like to search through both of them and create a type that i can sift through later
something like this doesnt work

I basically want to create a list of "AnimalSearchResults" that contains all dogs and all cats that have that name Whats the best way to do something like this?
I want to search an ASP.net form for all types of validation controls and programmatically add some attributes to them such as ForeColor. Can someone point me in the right direction on this?
For this applications, I will have a table that has a list of users who are "moderators" and they are able to see a part of the website that regular users cannot. I will NOT have a login or anything like that - I have a table that lists all the users who are moderators and if the user who is logged in is a moderator they simply see more of the website.
Right now I am able to get the username of the logged user (these are users who log into a Windows machine, and I simply get their login using a method from System.Security).
The thing I have no idea how to do is actually compare the username to the username in the database that I have. can anyone point me to a tutorial or something that searches through a database to compare the given value and see if there is an identical one in a specific database? I don't want the user to see the database, this is all done "behind the scenes".
I have a list of files in excel spreadsheet. I want to open the excel spreadsheet and search for those files in c: directory and then copy those files from C: directory(whatever folder they are in) to another directory( C:Test1). I already wrote the code to loop through the excel spreadsheet. Below is my code.
