I have this interface of multilevel grid built in VStudio 2010 using asp.net.My grid will show the 2nd level then the 3rd (2nd grid as its parent) when plus signs are clicked. however the parent gridview loses its original width when the panel shows up. Is there a way to maintain its width so the design will be as is. See the picture by clicking the link

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.

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.
I have a product category table with the following fields:
cat_id (PK)
Cat_name
Cat_desc
Parent_Cat_Id
Now when a user wants to add a product he should be able to select multiple categories from a listbox(multiselection enabaled). But to let the user know the hierarchy of the categories, I need to display them in the following style:
parent category 1
parent category 1->sub category 1
parent category 1->sub category 1->sub-sub category 1
parent category 1->sub category 1->sub-sub category 2
parent category 1->sub category 2
Parent category 2.........
I know that to achieve this I need to use recursive programming. But how can we do it via stored procedures?
I need to display data in GridView with Multileve hierarchy same like Treeview.
View 5 RepliesIs there any way to set the width of a GridView to a pre-determined width?
I have set the width of the gridview and all the columns to a % and then to a number of pixels but it does work. The gridview always sets itself to a width required to display all fields and it goes beyond the resolution of the screen. I would like to contain it to 1024 pixels.

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

.I am new to asp.net.Is there any way we can limi the width of the gridview in the design mode.
I have to put 15-20 columns on the gridview.When I add columns to gridview the width shoots out of the page and the page design is seems ruined.
i placed it inside the panel and added scrol bars to it. it looks ok when debuggin i.e looks ok in internet explorer but in design mode it ruins the page design.
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.
I have designed a collapsible nested gridview project using this article as a reference Collapsible Nested GridView with Paging using ASP.Net. I am trying to modify the code to collapse a gridview when another gridview is expanded so that only one nested gridview will be open at a time.

View 1 RepliesI have a dropdown list in a gridview field. The DataValueField for the ddl is an 8 digit item code. The text to display through will be quite longer, 40-60 characters because it will combine the item code and item name into a single string. I don't want the dropdownlist field to be that wide though, only what is displayed when the ddl is selected.In Access you can set the width property of the list to display wider than the field itself. Is there that capability in ASP.NET and if so where do I find it?
View 2 Repliesi Have a dynamic column gridview control in a page hosted in sharepoint. Grid is binded to an XMl and placed inside a Div control. I have set rowstyle-wrap=false and width=100% and overflow of parent Div to auto
There are only 2 columns in grid that can have long size text data (with and without spaces between words).
Problem
1. When grid has lot of columns (say 20), a scrollbar appears on the IE window(as page content is out of windows size); but the two columns that have long text values in them, gets wrapped.
2. when grid has less columns (say 5), no scrollbar appears in IE windows(as page content fits within window).but the same two long text columns, doesn't get wrapped and render in a single line.
Is there any max width of gridview? I want that grid should take all the space (as per content) and show scrollbar; the content should not get wrapped.
how to make grid content not to wrap and expand to any width.

i could get the inner gridview onRowDataBound working by setting that directly in the gridview

I have a nested gridview which has been working fine. Now I need to turn the inner gridview off based on some condition: a IF block is added to the existing RowDataBound event of the outer gridview. Now I'm getting "the Object reference not set to an instance of an object" error. What should be the proper way to go about this? The code:
[code]....
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?
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:

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'.
</ERROR>
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?
