Forms Data Controls :: Update XML With Textbox And Command Button?
Apr 8, 2010
I'm trying to create a ShoutBox for my site, and for those of you who are not familiar with shoutboxes, they are chat boxes on websites that users can post live messages on, and the other uses will see their message and be able to respond. I didn't find any good ones online, so I started to write my own. I'm doing it with an XML, but I want the user to be able to post messages using a textbox I added (txtMessage) and the button (cmdPostMessage), which should add a new item to the XML file, and all the other uses will receive that message (their xmlDataSource and the DataList will PostBack every second or something like that). It is able to read messages, but not send.I am however facing three problems:
1- I need to find a way for the user's input to be added to the XML.
2- I need to find a way for the current logged-in username to be found, and added to the XML, and also detect if no user is logged in, in which case the user wil receive an alert saying "Please log in to post messages to the ShoutBox" and redirect them to the login page.
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 have 3 gridviews in one of my web page, each of which will display different data based on the typeid. I have simplified the system structure in the image below(further description will be stated below the image):
As shown in the image above, the web site(presentation layer) will work closely with the Business Logic layer(BLL) and Data Access Layer(DLL). ObjectDataSource control will be the middle man to select, update, insert and delete the data in the gridviews.
During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
[code]....
However, the Update(command button) and Delete(template field) doesn't work,the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource.
I have a GridView with two templatefields, one with a DropDownList and the other with a TextBox, both loose their values once I hit the "update" button. Is it any way I can make the controls keep the values?
i'm trying to update the data from the textbox using the update button at one of my accordionPane. but when i click the button it won't go to the Accordion1_itemcommand. how to fix my problem??below are code
I have 3 gridviews in one of my web page.

During Select, returned data from the database at DAL will be stored in a datatable and return to BLL and then the website itself.
The data in the returned datatable will be filetered by type using RowFilter method and stored into the 3 dataviews. Each dataview will act as the datasource for the 3 GridViews respectively, and therefore I specified the datasource programatically instead of setting the datasourceid for each gridview.
However, the Update(command button) and Delete(template field) doesn't work, the RowUpdating and RowDeleting event wasn't trigger when I click on the button, but it works if I set the gridviews' datasourceid to the objectdatasource. I couldn't figure out why, hope that someone who have come across the same problem couldn't provide some guidance.
I am trying to use an Update Command within my GridView. I need to find the "FindControl" for the Edit Command textboxes.
Ie. When the user clicks the Edit button, the row is populated with dropdown boxes, textboxes, etc for editting. Then when the user clicks on Update (button) and the GridView1_RowCommand function is activated with 'if (e.CommandName == "Update")' statement with my FindControl. etc. and my sql UPDATE command statements are used. How do I convert my FooterRow info to my Edit FINDCONTROL info?
I am using asp.net(C#) as platform for building my application. I want to update the values in the database for the particular user & using the following code:
[Code]....
when I run this code, it works perfectly fine & there's no error, but when I check into the database, the values do not change & remains same. The default value in the database is NULL.
I have a asp.net gridview control on my page with several fields and a couple of command fields. However, the update command is giving me problems.
Here is what works. The update command works provided I put straight text into the textboxes that appear. I even have one field that contains a dropdown list which works fine.
Here's the problem. I have two fields that need to access their value programmatically. These fields will reflect the current datetime and the current loggedin user from active directory. I have already created public strings in the C# code.
When I run the edit command on the asp form the grid uses one "DataKeyNames" element. With this the grid can update the selectedrow. However, I haven't been able to access it programmatically in the C# code. I can access the selectedrow in the "selectedindexchanged" event but then I am not able to update my fields in the gridview itself. So, part one of my question is how to I access the "DataKeyNames" properties of a gridview control.
if I can't access the "DataKeyName" property perhaps I could set the label nested within the gridview to the "myCurrentUser()" public string. I am inserting my code to hopefully make this clearer.
I have a simple table, ID,Fruit,StockSo, the rows are its primary key (ID), Fruit type (Orange, Apple etc) and Stock (1 is it is in stock, 0 if it is out of stock).I have a grid view on a page which lists the rows.What I would like is a button that executes a SQL command based on the row.(The command is just an update to change the Stock field from 1 to 0).The query i tried was UPDATE [Table] SET [Stock] = 0 WHERE id = @id
I have a gridview and sqldatasource in a form. My sqldatasource has select,delete and update command. The delete command is working but the update doest not work when I click the update command field.
Bug: UPDATE command Does NOT Work as Expected on a DataBound GridView This was tested in VS2005 and VS2008
Took a while to figure this out - A simple recurse thru Page Controls Makes UPDATE Not Work as expected.
To Recreate this bug:
A simple Gridview bound to an Objectdatasource on a page with ALLOWEDIT ALLOWDELETE
If one inserts some code (a function call in my example) that just recurses the PAGE controls in either the PAGE_PREINIT, PAGE_INIT, PAGE_INITCOMPLETE events,
Then the UPDATE does not FIRE! and After Pressing UPDATE the GRID does not BIND! You Get A Blank Page - Funny thing tought it's only the UPDATE Functionality that gets affected by this - Everything else works fine including EDIT & DELETE.
If the same function call (recurse thru page controls) is added in the PAGE_PRELOAD, PAGE_LOAD -- Then the UPDATE starts working again as expected.
BELOW Is SAMPLE Code using the NORTHWIND DB Products Table and a Typed DATASET.XSD - You can use your own datasource for the ObjectDatasource - (Note I took out the Foreingkey constraint in products table from Nortwind for delete to work)
NOTE: One should be able to just cut and paste the function PAGECONTROLS_RECURSETEST on any working form that has a bound Gridview with Update functionality and you should be able recreate the bug that way by calling the function from the different page_events
What I want is here that ; I want to specify the button's command arguments according to selection of radio buttons which is in the same group. I want know that which price type is selected return or one way.
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.
I have problems with gridview that has command button in it. The command button (when clicked) should redirect to another web page, but instead of doing it only does postback on current page.
I have a gridview where I am looking to do a custom command with a template button. I am trying to get the current row that is being selected, but I cannot seem to figure out what I am doing wrong. Here is the gridview source:

Here is the code once you click the "Quick Update" button

I am getting the error message of "Object reference not set to an instance of an object." when it tries to do this line:
I am using Repeater control. In DataBound event I am preparing output of item and everything works ok. But now I need to add a command button to item. I cannot add button to item template in designer (some project specifications do not allow it). I create new button at DataBound, set unique ID, command name and argument and bind it to command event and, thenm place it to Item controls container. It is not working as command button.
I am collecting user data using 3 detailsView, dv1,dv2, and dv3 each connected to sqldatasource , ds1,ds2,ds3. I would like the user to click one button(InsertBtn) and add all the data entered in each detailsview. I added
ds1.insert(); ds2.insert(); ds3.insert();
to OnClick event of InsertBtn. But the data does not get inserted...?? How can I make the user click one button and add the datas in each detalsView to database..???
I want to know how we can get the command argument of a Image button in Javascript.
Scenario:
I have a grid in that I have image button in template column.on click of each image button i have to redirect to another page with respective ID fields.
I would like to add a command button at runtime. Can someone show me how or point me in the direction. I googled it without success.My design code and code behind is below.
