Forms Data Controls :: Trying To Create A Nested Gridview, But I'm Stuck At The Editing/deleting Part Of The Nested Gridview?

Mar 1, 2011

I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

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 :: CSS Friendly Adapter For Gridview Causes Nested Ajax Calendar Control's Table To Inherit CSS?

Feb 2, 2010

I was having issues with a gridview and CSS so I posted my question here and received a wonderful answer which lead me to implementing CSS Friendly Adapters for all of my gridviews.I have a table nested in the EditItemTemplate that holds the textbox and the button for a calendar control where I want them, it inherits the CSS applied from the CSS Friendly Adapters. I don't want it to change the CSS so I have changed the CSS inline, with no success. More importantly...

I also have a Ajax calendarExtender control to change the date for that field. When the popup is displayed the table in which the calendar is shown in also inherits the CSS Friendly Adapters code. I have tried fixing this by creating a external css sheet for the calendarExtender's cssClass property and a blending of CSS occurs where the items not specified by the Friendly Adapter Code are set correctly by the calendar.css file that I created.Is there anything that I can do to force the tables inside of the gridview to ignore the inherited Friendly Adapter Code?

In Nested Grid, we get a '+' sign.   The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.

Forms Data Controls :: Using GridView With A User Control And Passing Object Into Control?

Jan 8, 2010

I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.

Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control

Forms Data Controls :: Nested GridView Control Returns "Object Variable Or With Block Variable Not Set" ?

Oct 20, 2010

Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.

The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....

Object variable or With block variable not set.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object variable or With block variable not set.

Source Error:

Line 118: If e.Row.RowType = DataControlRowType.DataRow Then
Line 119: Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource)
Line 120: If Not e.Row.DataItem("Status_ID") Is Nothing Then
Line 121: myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
Line 122: End If

I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:

*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)

*If Not localLblItemReference Is Nothing Then

******************************************************************************************

To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.

In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:

Exception Details: System.NullReferenceException: Object variable or With block variable not set.

Forms Data Controls :: How To Access The Properties Of The Inner Gridview Of A Nested Gridview

In addition, is there a way to "switch" columns of the inner gridview? For example, column 1 is "City", column 2 is "Price". If user selects to sort by "Price", I woud like column 1 be "Price" and column 2 be "City". Is this has to be done programmatically or if there's other way?

Forms Data Controls :: Child Gridview Editing On Dynamically Added Nested Gridview

Jan 3, 2010

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.

OnRowEditing="grdChildGridEdit_RowEditing"

The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).

I was trying to trigger it throughuse the registering the event:

Forms Data Controls :: Nested Gridview Render Underneath The Outer (parent) Gridview?

Apr 13, 2010

Using vb.net/asp.net 2005

I have a nested gridview (gridview within gridview) that I need to render beneath the outer gridview.

I keep finding examples online of showing a nested gridview in the last column of the outer gridview but I need to show my nested gridview instead under the outer gridview.

I was certain that I had done this before by putting a row (<TR>) inside the TemplateField so that the nested gridview would display under the outer gridview. I am getting the data ok for the nested gridview, that is not a problem. The only issue I am having is making the inner gridview display under the outer gridview.

btw, the error is below:

<ERROR>

Type 'System.Web.UI.WebControls.TemplateField' does not have a public property named 'tr'.

Forms Data Controls :: Nested Gridviews: Get Parent Gridview Rowindex From A Child Gridview?

Jun 15, 2010

I have a nested gridview containing gridviews: gvMaster(Parent) and gvAlternate(Child)

If I select a row in gvAlternate is there a way for me to find out what gvMaster row it is under? I want to highlight the selected gvAlternate row and the gvMaster row that it is under.

[code]....

I can get a certain set of rows of gvAlternate only by referencing which gvAlternate control set I want to access: this is based on the gvMaster.Rows and then using the FindControl and id name:

GridView
gv = (GridView)this.gvMaster.Rows[aRowNumber].FindControl("gvAlternate");

Therefore, it is true that a set of rows in a nested gridview is tied to a specific row in its master gridview, the question is does the child gridview know which set it's connected to or does it's master know if a childset has been selected?
