Web Forms :: Validation On SQlDataSource With GridView?
Jun 6, 2010
I created a grid view control and linked it to sql database and added "edit" and "delete" options. How can I perform validation on the created "update" button ? Basically, I want to be able to make sure the proper fields have been entered before the database gets updated? Also, I would like to be able to display any errors after this validation to a validationsummary control? Below is my sqldatasource code and gridview:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConflictDetection="CompareAllValues"
ConnectionString="<%$ ConnectionStrings:CustomersConnectionString %>"
DeleteCommand="DELETE FROM [Products] WHERE [ProductID] = @original_ProductID AND (([Productname] =
i designed a gridview to update, delete the records using sqldatasource, (there is no code in my aspx.cs file) but i dont know how to add the new row the gridview. so that if the table is empty then i cant add / update / delete the data.
how to Add new record on gridview using SQLDatasource without any code behind code?
I have textbox that searches for first or last name. Result show in gridview. But when add value in text box and push my button Find nothing happen. Here code:
I have a gridview and a SQLDataSource control. In my gridview I have 2 commandfields "Edit" and "Delete"
The "Edit" command field works as expected. Using the "Delete" command field I get the error below.
Server Error in '/DataControls' Application.
The DELETE statement conflicted with the REFERENCE constraint "FK__titleauth__au_id__0CBAE877". The conflict occurred in database "pubs", table "dbo.titleauthor", column 'au_id'. The statement has been terminated.

I have a database which holds the scores in the league for my local table tennis club. There are 3 divisions. On the admin page, I want the admin to be able to add teams and edit the scores. For each league, there is a seperate gridview. How can I use just 1 SQLdatasource to filter the records for each gridview if all the teams are in the same database with the division next to their name? I'm new to web development.
Can you add a row of data programatically and bind it to the gridview? If so, how?
I have a grid with 2 columns. One of these columns is a template that runs a function and delivers an output. Within that function I need to manually add data that is not present in the sqldatasource to the grid and use it when performing aggregate functions.
ColumnA - ColumnB 1 - MyFunction(1) - adds new row (1, B)and returns A to column B. 2 - MyFunction(2) - May return just A
Grid should look like 1 - A 1 - B 2 - A
Even though SQLDataSource only returns 1 - AB 2 - A
I I have a GridView attached to a SqlDataSource and all is working well. I also have and edit and delete icon attached to each record in the GridView, and again, all is working well.My problem is when I add a BoundField named 'statusCode', the delete stored procedure fails with:"Procedure or function 'up_delReference' expects parameter '@statusCode', which was not supplied."When I remove the BoundField named 'statusCode' from the GridView list, the delete works fine. I need to show the status in the GridView as the user can chose to see Avtive, Inavtive or Both records and they need to see the status when in Both.Here is the Code:

With asp 2.0 and vwd 2005, I have a page with a radiobuttonlist, textbox and gridview with edit/delete. Using the radiobuttonlist, the user selects a search type and then enters the criteria in the text box. the click event of a submit button checks the rbl.selectedindex and chooses a sqldatasource.selectcommand with the where clause getting its criteria from the textbox. The gridview loads the data, but the edit/delete are not working. Code and relevant markup is below
I am trying to put the select command in code behind:
sdsAdd.SelectCommand = String.Format("SELECT Classes.ClassId, Committed, CallNumber, SubjectArea, CourseNumber, SectionNumber, GradingBasis, NumberOfUnits, NetId FROM Classes INNER JOIN EnrollmentAdjustmentClasses ON EnrollmentAdjustmentClasses.ClassId=Classes.ClassId WHERE AllFormsId='4' AND SectionId='1' AND NetId=@NetId AND Committed='True' AND EnrollmentAdjustmentClasses.FormId={0}", Request.QueryString["FormId"].ToInteger32()); gvAdd.DataBind();
When I do that, then click edit to edit the selected item, the item disappears from my gvadd. What am I doing wrong?
I'm having a gridview in my aspx page with checkbox, User can select one or more than one record(s) at a time and clicks on delete button, Then i'm constructing an object of my DTO and adding all the checked row's Primary Key (DataKeyNames - GUID's in my case) to a serializable class and generating an XML and sending it as parameter to the Stored Procedure.
My Doubt is, can i bulk delete all the rows from database table those are present in my XML document??
If it works, I can do bulk update with XML only, i already did bulk insertion by generating an XML..
My Another Question is, Will it affect the performance? Each time when i construct an DTO object and adding it to the Generic List?
Which one is better, I mean ObjectDataSource or SQLDataSource or my XML method?
I have a gridview that loads with a new datasource on button click event. On the gridview (which is located in a table columm incidentally) are 2 columns, a descriptor and a checkbox. The problem is that after postback, the column widths change, the checkbox column expands and the other column contracts. Is there a way to keep the gridview column sizes the same after postback?
I'm using VS2008 to write a web app. The page has 3 inputs (select date from calander, and items from two dropdownlists). User will be able to select any of the three or nothing. I start with a "select * from ... and append a where stmt to my select; depending on the user's choices. Once the user has selected (or not) they will click a "get info" button. That passes the select command to the SQLDATASOURCE, where it successfully returns what was requested. If I have PAGING enabled (perferred because there could be MANY rows returned), the first 10 rows return with the appropriate page numbers. When a page number is picked (ie. 2 or next), the page reloads and the query reruns but regardless of the original query; the rerun query selects everything. Obviously, this will not work.i'll even ZIP my code and email it to "you"; if needed.
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 having a strange problem - probably has a simple answer but, I haven't been able to find it or figure out the cause. I'm hoping someone has had this same problem and figured it out.
Basically - my application works great on the development machine. So I copy it over to the server and it works great. Come back the next day and my GridView is only displaying the first record...I then log into the server remotely and open the web page on the server and all records are returned, so the application works fine on the server. I then return to the local machine and now the application is returning all rows in the GridView. So, weird but, what whatever, it works. Go away and come back again the next day and...
1 ) Only 1 record from dataset is displayed in GridView
2 ) Log onto server remotely and view webpage on server --> all records now display
3 ) Try again on local machine, now application works fine...grr. What am I doing wrong here? Using Visual Web Developer 2008 on Windows XP. Querying SQL Server 2000 (I know, I should switch to 2005 and use VWD 2010 - but ouch, really!) when a text box value changes (Vendor_PO_TextBox.TextChanged)
Gridview has many columns and a Delete button as well. Delete button is a control as TemplateField
[code]....
Now associated SQLDataSource's Delete command's stored procedure is expecting two parameters. One is going from DataKeyNames (RowID), other one i wanna pass is the Text of btnDelete (True or False).
