C# - Gridview Capture SQL Select Command Being Executed?
Mar 22, 2011
Is there anyway to capture the command the Gridview is executing for later use? I have gridview that uses parameters from a few textboxes, so its generating a custom statement. I am wondering is there anyway for me to get that statement either during or after it is executing it, and then returning the results. I need to save it, so that I can populate a CSV file with the data that was returned?
I have gridview. some columns are data, and some are link buttons. now, I need move these link buttons to a hovermenu. this is done. but I got a javascript exception, and it is because if there is no row was selected in gridview, it will pop this.
so, the question is: how can I select a row in gridview without select command? simply by code?
i am using vs 2008 and ajax when i execute my application i had this error messageCannot execute a program. The command being executed was "C:WINDOWSMicrosoft.NETFrameworkv3.5vbc.exe" /noconfig @"C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Filesestwebsite_componenteditor2842527e6911f45cp1uobvpm.cmdline".
I want to issue an INSERT command for an SQL Server table using DataAdapter without first issuing a SELECT command. Could anybody send me lines of code to handle this? Also how do i manage INSERT into selective table columns (I have 10 columns but i only want to update 2 of them)?
I have a gridview bound to a dataset and I do not want to display the id column or the select hyperlink. How can I have a user click anywhere in a row and have the application behave as if they clicked the standard select hyperlink. the one or two approaches I have seen on blogs have not been successful for me. maybe I was missing a piece

I've recently started working in ASP.NET and RDBMS.I'm making a test form where I can do basic add,update,delete operations.I'm using OracleDataClient to do the DB operations.I was able to populate a listbox using OracleDataAdapter.
Now after clicking on update button,I intend to Update in DB.I've Dataadapter with it's update property.But the update query is not happening.The examples I saw over net all have Select command before Update.Is it actually like that or am I missing some point.
How does Oracle DataClient work with Insert,Update,Delete Commands.
Two ddl inside gridview. on selecting first ddl1 fill next ddl2 by passing selected value as parameter by executing the sqldatasource select command in codebehind.code:
GridViewRow gr = (GridViewRow)((DataControlFieldCell)((DropDownList)sender).Parent).Parent; //find the control in that DropDownList d1 = (DropDownList)gr.FindControl(ddl1); DropDownList d2 = (DropDownList)gr.FindControl(ddl2); SqliaDataSource.SelectParameters.Add("@name", d1.SelectedItem.Text.ToString()); dataView dv=(dataview) SqliaDataSource.select(DataSourceSelectArguments .Empty); Error: There is no source code available for the current location. and Returns null value
I'm programming a webpage in ASP.NET which displays a list of students not listed as participants in something, and upon clicking a student name shows you a brief summary of their details, so the user can ensure they're selecting the right person.
My code currently correctly obtains their ID, adds it as a parameter to my stored procedure and executes the procedure;
[code]....
However, when I try to access the results I get the following error:
System.NullReferenceException: Object reference not set to an instance of an object.
Upon debugging, there don't seem to be any results returned... but when running just the stored procedure in SQL Server with the same data, it does return a single row, as expected.
How do I access this result so I can bind it to my fields?

i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource(); sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString(); sq.SelectCommandType = SqlDataSourceCommandType.Text; sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1"; string result = sq.Select(some overload that's stopping me);
I've read that OnClick is executed on the server and onClientClick is executed on the client. Is it better to use OnClientClick to do something like close a modal popup?
If my understanding is correct then this would avoid a trip to the server to accomplish the same task. This would be great for something that doesn't need to make a round trip to the server and back.
I'm trying to add a second command field to an asp.net gridview. Essentially, I want the user to have the options to delete and update records on one page. I've gone through gui's to do this that I have found on the web but none of them work. I think that this is because of the fact that I am working with Visual Studio 2008, so the gui's don't match. Plus, my datasource isn't allowing me to add delete parameters, and update parameters. So, my present goal is to have multiple command fields in my gridview. This would also enable me to add a "duplicate record" functionality, as is needed with this program. I would also like add functionality. If possible. I've been doing all this on multiple screens but I believe I should be able to do this on one screen. Here is my gridview and datasource.
I have problem on page bellow, in gdvCar_DataBound I add three buttons, when I click on any of them, page go to postback but doesn't enter in gdvCar_RowCommand and then that buttons ( and images that I also add in gdvCar_DataBound) disaper.

In regular old visual c#, if I wanted to select all the text in a text box I would use testbox.SelectAll(); (or something like that, can't remember if that's the right method name).
In asp I can use focus() to put the typing cursor in the check box, but I can't for the life of me figure out how to select everything in the box so that the user doesn't have to highlight it to start over.
Is it possible to have multiple conditions in an SQL select command. I have an SQL Table with the follwing filds.
Image1 Image1Approved Image2 Image2Approved Etc
Image1 is a varchar(50) and stroes the picture name. Image1Approved is a tinyint (0 = Pending, 1 = Declined & 2 = Approved) I am using the following to query the SQL database.
SelectCommand="SELECT Image1, Image1Approved, Image2, Image2Approved, Image3, Image3Approved FROM UserProfiles WHERE (UserId = @UserId)"
The part that I am stuck on is only returning the images that have there associated approved condition set. I know how to do this with a seperate select command for each image but can this be done for all image files in one statement.
In my DB some tag will get automatically concatenate with original value, this will happen in few tables and in few columns(nvarchar type).What will i do for avoiding this.Here is that tag:
After trying many solutions listed on the internet I am very confused now. I have a C#/SQL web application for which I am simply trying to bind an ExecuteReader command to a Dropdownlist so the user can select a value. This is a VS2008 project on an XP OS.
How it works is after the user selects a table, I use this selection as an input parameter to a method from my Datamatch.aspx.cs file. Then this Datamatch.aspx.cs file calls a method from my ADONET.cs class file. Finally this method executes a SQL procedure to return the list of columns from that table. (These are all tables in Adventureworks DB). I know that this method returns successfully the list of columns if I execute this SP in SSMS. However, I'm not sure how to tell if it works in VS or not.This should be simple. How can I do this? Here is some of my code. The T-sQL stored proc:
CREATE PROCEDURE [dbo].[getColumnNames] @TableName VarChar(50) AS BEGIN SET NOCOUNT ON;
[code]...
The CreateLabels method above correctly shows me the labels. But the CreateDropDownLists method just shows me one dropdownlist with nothing in it. In other words, it is not selectable. So how can I verify that the datareader is returning all 4 columns and inspect their values? I was able to find from datareader "COLUMN_NAME" but I don't know what properties to search to verify the column names.
I have a table and on this table I have two column showing NumberOfDays and TotalPrice. I have my select command just like below;
"Select ([NumberOfDays]*[TotalPrice]) as MyResult From MyDatabase Order By [MyResult]"
My aim here is to create a new data depanding on 'MyResult' value. If MyResult value is under 10, I want a data value as 'False'. Else, I want a data value as 'True'. How could I write it in sql code?
I have a textbox in asp page wherein it should take multiple values separated by comma's to select command as input. The same I have done using C# page, but now trying to have the entire query in aspx page itself.
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> //GridView code <asp:SqlDataSource ID="Sql1" runat="server" ConnectionString="test" SelectCommand="SELECT Name WHERE ID IN (@TEST_ID) from EMPLOYEE ORDER BY 'Name'">
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...

I need to display a single field from an sqlserver table, do I need to use sqlDataSource ect. or is there a simpler way (like msaccess's LookUp) for single values.
I would like to know if I can do the following: when I am in insert mode, can I dynamically change the select command of and then display that result in the second dropdownlist based on what was selected in the first dropdownlist.
I would like to include the minimum code to demonstrate what I am trying to do.
