Forms Data Controls :: Binding A Gridview Nested List Control Based On Field Value?

Dec 10, 2010

I need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?

protected void UserGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
int UserID;

Forms Data Controls :: List Box Nested In Listview Control Selection

Jul 5, 2010

I have a list box in a list view control. I want to access the value of the listbox. I have fixed the height of the list box and the box has scroll bars. If i change the number using the scrollbar and then click on the number (turning it blue) everthing works fine. If I simply change the number using the scrollbar the system throws the error below. Can anyone tell me how to get this to work simply by using the scrollbar to select the number (without having to also click on the number itself) This is the error that is thrown

This dropdownlist is populated by a column in thetable . This drop down list may have values ranging from 1 to 5.

This values in the dropdownlist are to be made the caption headings of the list view control.

For insance if there are three values in the dropdown there should be three columns in the list box with the heading as the values of the dropdownlist.for 5 it should be 5.

Forms Data Controls :: Escape Apostrophe When Binding To Hidden Field In Gridview?

Apr 15, 2010

I've got a gridview with a hidden field, i'm trying to set a value as follows:

value='<%# DataBinder.Eval(Container.DataItem, "Name")%>'

which works in most cases except when the name has an apostrophe like O'Neil. I need to escape the ' if possible.

so i tried: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " /' ")%>' and

value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " //' ")%>'

which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.

This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '

Forms Data Controls :: Select A GridView Row Based On Field Content?

The Listbox has a list of students. The Gridview has a list of classes offered during a period, such as:

What I need to do is Highlight the record in the GridView that matches the ClassID or ClassTitle returned by the sproc.

Previously, I used a ListBox for the Class Offerings. This is easy with a Listbox using the FindByText method:

Forms Data Controls :: GridView Page Reset Based On DropDown List Selection?

Jan 3, 2011

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.

How do I reset the grid view page back to the first page of August 2010 sales?

I am fairly new to ASP. If I have missed an imp. detail in this post, let me know and I will get that info. out there.

Forms Data Controls :: Dynamic Gridview With Dropdownlist / Dynamically Set The List Values Based On Parameters (of The Row They Are On)

May 28, 2010

I'm new to web dev and c# so please bare with me. I am trying to create a dynamic gridview in a web form for users to to answer questions with (code below).

The dificulty im having is that i am nesting a dropdwonlist in the gridview and want to be able to dynamically set the list values based on parameters (of the row they are on). These values are in the main dataset for the gridview as each row represents a questionid and question text and then a ddl for the criteria...

I just don't know how to set the values for the dropdown all the code so far is below... just need to be able to populate the dropdowns with the relevant values.

I have created a stored proc to return the different criteria based on the questionid and questionGroupid which is the dataset that populates the other fields in the gridview: dbo.usp_QuestionCriteria @QuestionGroupId, @QuestionId

I have added this as a tableadapter called criteriaTableAdapter in a xsd file as well using the wizard... not sure if this is the right option though or just use the same method as i have for the other stored procedure as in the code below:

Forms Data Controls :: Looking For Clean Approach To Building Nested Datalist Or Nested Gridview

Jun 17, 2010

Is there a better, cleaner way to do this in ASP.NET 2.0?

An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.

The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.

The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

Forms Data Controls :: Giving The Panel Control A Dynamically Bound Value (3 Way Nested Gridview)?

Jan 5, 2010

I have a 3 level deep nested gridview. The expansion/contraction of each record was originally done with javascript. There were html <div> tags around each gridview. Since these were HTML div tags I could give them IDs that were dynamically bound to record ID value within the database. I then had onclick buttons that passed in a bound record ID value that coresponded to the appropriate div tag that needed to be expanded (e.g. display: inline (show it) or if it is already inline then display: none).

This worked beautifuly. Unfortunatley I wanted to be able to do in-girdview editing of the child records. When expands a parent record and clicks to edit a child record the OnRowEdit event fires which automatically generates a postback and resets the variables within the JavaScript. THEREFORE THE ENTIRE GRIDVIEW STATE BECOMES CONTRACTED.

So finally I decided to change the div tags to <asp: Panel> and the onclick images to .net clickable images (all .net objects no framework). This works because the state is remembered within each postback. However, the problem I'm having is I can't dynamically bind ID's for panel since this is not allowed. HOW CAN I GIVE THE PANEL <% Bind("id") %>. THAT I CAN REFER TO SO I CAN OPEN THE APPROPRIATE PANEL.

Forms Data Controls :: Creating Data Table In Memory And Binding To Gridview Control?

Jun 24, 2010

I'm a bit of an ASP.NET newbie and I am creating a data table in memory and binding this to a gridview control. The code is as follows:

Dim DstBasket As New DataSet, TblBasket As New DataTable
With TblBasket
.Columns.Add("BskPrdCd", System.Type.GetType("System.String"))
.Columns.Add("BskPrdDesc", System.Type.GetType("System.String"))
.Columns.Add("BskQty", System.Type.GetType("System.Int16"))
.LoadDataRow(Split("12345,Test product 1,1", ","), True)
.LoadDataRow(Split("122,Test product 2,2", ","), True)
.LoadDataRow(Split("123A,Test product 3,5", ","), True)
.LoadDataRow(Split("44,Test product 4,1", ","), True)
End With
DstBasket.Tables.Add(TblBasket)
With LfnGridView("GdvBasket")
.DataSource = DstBasket
.DataBind()
End With

The data displays in the gridview control fine with both edit & delete options but when I attempt to delete, it has no effect. How do I force removal of the relevant row from both gridview and table? Most of the documentation I have unearthed shows how to achieve this when connected to a SQL table which is clearly not the case here.
