Forms Data Controls :: Parent/Child Datalist Displays Correctly Sort Of?
Jan 11, 2011
I have created a search page for web application that will allow a user to search the database based upon employee name or supervisor name. It is a multiple table database that is linked together by an unique employee number column, primary key in people and foreign key in supervisor. I have a parent/ child datalist used to display the record. When searching by the employee name it will return the record correctly if there is a record found. However, if I search by supervisor name and there is no match for the supervisor name, it will return all the records and create the parent datalist with all the employee details there, but the child datalist with the supervisor information is not display as there is no record with that supervisor name.
In the ASPX.CS file I define a datasouce and manually populate it.
DataColumn MDC = new DataColumn(); MDC.AllowDBNull = false; MDC.AutoIncrement = true; MDC.AutoIncrementSeed = 1; MDC.AutoIncrementStep = 1; MDC.ColumnName = "B2"; MDC.DataType = System.Type.GetType("System.String"); MDC.Unique = false; MDT.Columns.Add(MDC); MDC = new DataColumn(); MDC.ColumnName = "PRPT"; MDC.DataType = System.Type.GetType("System.String"); MDT.Columns.Add(MDC); I then manually fill each row: DR = MDT.NewRow(); DR["B2"] = "Test1<br/>Test2"; DR["PRPT"] ="Test3<br/>Test4"; MDT.Rows.Add(DR);
When the Grid is viewed using IE - both the Header and the data rows properly display the cells with multiple lines. When displayed using Firefox or Safari - only the Header utilizes multiple lines - the data rows are on a single line ---- "Test1Test2" what needs to be done to display multiple lines in all three browsers.
I am using a collapsible child gridview inside a parent gridview. When I click on the expand image, the data to displayed is put up correctly, however when I make some changes in the child gridview, they seem to be lost!! That is, the changes do not get reflected in the database.
since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.

Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
I have a treeview and all nodes are check box, when user clicks on a button, how can I get all the checked child nodes belongs to specific parent? I wanna something better...
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
I have a requirement where I need to show the data in parent/child form .For Example - Lets says we have have customers and each customers can have multiple orders.I need to display it like this -
Cust1 Info about the customer Gridview (showing all the orders for the cust1) Cust2 Info about the customer Gridview (showing all the orders for the cust2)
I have a datalist, this datalist control is bind, when user select control filters,i am looking a way to sort this datalist control for example like asc or desc or price.
Within the EditItemTemplate and InsertItemTemplate I have a cell that has a textbox and a button.
When the button is clicked a popup window is shown, where the user can upload a picture. The name of the uploaded picture is retrieved.
Now I want to send that picture name back to the textbox within the listviews EditItemTemplate or/and InsertItemTemplate (that is ofcourse one at a time depending on what the user is doing, inserting or editing a row).
The code I have written so far looks like this. The below code has been abbreviated
[Code]....
The code behind looks like this (also abbreviated). Actually I don't think the code behind is needed, since its mainly javascript from the popup window (child page), but nevertheless here it goes.

And at last the child page / popup page.
Well there is not anything to see here, cause I'm using the Telerik RAD upload control, which is doing everything for me.
However the line below may be of interest. Here I'm taking the name of the uploaded file (picture) and printing it to a label.
Im using Nested DataList in My Application. But i m not able to find control Inside Child DataList. (I want to Find Label Control In ItemDataBound Of ChildDataList)
Simple and blunt: my cascading dropdownlists clear when a postback occurs. Does anyone know a quick way around that?For more information, read on...
I have 5 dropdown lists that define a training class location and line of business: Site, Parent Client, Client, Program, Project I'm trying to build cascading dropdownlists that can work from any direction (i.e. select a site and all other lists are filtered by site...select a project and all other dropdown lists are filtered by project). I've built the SQL Select statement behind the lists that filters (accurately).
I am working in Asp.net 4.5. I need to create a grid as like below, I am struggling to make the merging cells and make it as multi header row by combining all the cells...
Is there any sample to make gridview like this.... I need to do this on codebehind. I browse through the internet and found couple of sample but those are not having the header like i posted. I am little confused about making full header as merged cells....
Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'. In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I have an excel sheet which has several parent records/rows and every parent row/record has several child sub-records under it. I have a field called ID which is of the type String as it contains a mixture of characters and numbers and is common for both parent and child records. How do I store the parent and child records in separate database tables, retrieve them and display them in a nested gridview?
I have nested gridviews, in the outer grid I am displaying the question and in the inner grid 4 options are displayed in radiobuttons. I have kept Lock Answer button inside Item Template in inner gridview , so this button is coming with each and every question and when i click on Lock Answer button in front of any question, its saving the corresponding answer in the database. For ex, if there are 10 questions this button is coming with all the questions, all the questions are on single page and all are multiple choice. Now everything is working mine, my requirement is that I need on 1 common Lock Answer button at the bottom of the page and not with all the questions. And when I click on that common button it should run for all the questions that are displayed on the screen at should fetch and update each unique answer corresponding to that question in the database. Below is my code:
I am binding Gridview using json (first Gridview),which have some column with linkbutton. I want to bind other gridview(second Gridview) using json on click of Linkbutton inside first gridview . how to fire json on linkbutton click event ?
I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
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.
