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.

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)?
View 2 RepliesTwo 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);

Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. error when I place a drop down list into my instert item template of my listview, but I have the exact same control in my edit view and it works fine, any reason I am getting this error? I know what it means but why would it work in the edit mode, and not the insert mode?
View 2 RepliesI'm using a listview control to do a survey stuff. Everything is working perfect to present the data questions, to be answered text with the different type of controls radiobuttonlists, checkboxlists, dropdownlists, etc. The admin can modify, create, change questions, answers, etc. on the survey.When it's select, edit, or insert it's easy to find the control inside a listview.However, I'm wondering how to post user's answers back to DB. How to find controls inside the listview to grab the entered data/responses from there using let's say the submit button that is outside of the listview.I believe there should be a way to do it as otherwise why we put radiobuttonlist on a listview that somebody could click it and then we should be able to get that entries. Or I'm too optimistic on this control?
View 2 Repliesi'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);

View 3 RepliesSo, I have a button inside a listview:
[Code]....
with a commandName="confirm" and its CommandArgument the memberid from objectdatasource. I have create a code behind to put certain action to the said button..
[Code]....
But it has no effect. Did I make some mistake? I'm still new in this ASP.Net things.
in the nested ListView (or the child ListView), the edit command does not work.
It seems that the <EditItemTemplate> is not properly excecuted by the edit button in the <ItemTemplate>.
Interestingly, the edit command in the parent ListView works well.
The insert and delete commands in the nested ListView also run without any problem.
But I get no change by pushing the edit button which is located for each reply (the item of the nested listview)
Here is my code.

Within my ItemTemplate on a listview i have a link button carrying out a delete command. As it's a custom command i use the ItemCommand to do the deleting and have a stub itemdeleting.
It works fine set out like this however i only want the delete button to be available to logged in users. If i wrap the linkbutton in a loginview and then click on it the ItemCommand and ItemDeleting never get called the page just refreshes.
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;

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 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
View 4 RepliesI have a details view to insert some data. I want to validate this data myself. use the ItemCommand to trap the insert command. If the data entered does not match what I need, I want to somehow stop the insert procedure at this point.
View 3 RepliesMy web form contains a detailsview control that I have added a templated field to with a DropDownList in the InsertItemTemplate. The DetailsView default mode is 'insert. My detailsview is attached to a sqldatasource that has a stored procedure in the db to handle the insert. When I enter data in the fields and select insert all values from the detailsview are written to the table except for the selection that was made in the dropdownlist. I am using the ddl.selecteditem.value to populate my variable however when the insert method is envoked it doesn't send my value. The DDL value that I am capturing does not need to be written to the table it is just a flag for some variables that need to be set at the stored proc level. How do I get the DDL selected value to be sent with the insert statement?
Here is my code behind:
Protected
Sub
DropDownList1_SelectedIndexChanged(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Dim temp
As DropDownList
Dim AccessLevel
As
String
temp = AddUserDetailsView.FindControl("DropDownList1")End
Sub
AccessLevel = temp.SelectedItem.Value
Label1.Text = AccessLevel

I've added a simple SqlDataSource to my site with insert properties. I've also created some code behind to capture the insert command (oninserting="SqlDataSource_NewsLetterSubscription_Inserting").
Thing is how do I actually trigger the command to 'insert' from a standard button?
<asp:SqlDataSource ID="SqlDataSource_NewsLetterSubscription" runat="server"
I am using a gridview in (Visual Studio 2010) to display records from a SQL 2005 database. I can filter my date range successfully but it does not include the end date. I have tried using the between expression as well as >= <= to return the dates from the beginning and end dates. I have search and found that this is due to the time portion of my datstamp in the SQL column (02/19/11 01:03:36 PM) where I am filtering by short date (02/19/11); therefore leaving the end date out of the records returned.
Now the solution I have read is to add a day onto the endate like this: 02/19/11 + 1 but I get a conversion error returned from the SQL server. I have tried to use convert in this matter to convert the textbox.text in the selectcommand to datetime 101 formats to overcome this but I must still be missing something because it comes back with another SQL error unable to convert nvchar to datetime.
In the end I would like to have my two textboxes StartDate - EndDate filter the dateStamp column in my Transactions table and if both textboxes have the same date return records for that date only and include the EndDate if the range is more than one day.
I have tried many different variations of the below code using $,#,+ and & symbols to encapsulate the EndDate controlparameter to add a day to the EndDate and have failed at all attempts.
This my markup that filters fine excluding the EndDate;
[Code]....
I have tried using this as well and work excluding the EndDate:
[Code]....
selectcommand="Select * from Transactions where DateStamp Between @StartDate and @EndDate">
i have gridview i added it select command field i want when it is clicked,the id of the table displayed in label and i have update command field but the problem the update can't update the primary key i want when it is clicked update all the record
