Data Controls :: RowDataBound Event Of Nested Child GridView Is Not Firing?
Dec 4, 2013
I have a Master/Slave GrisViews or some say Parent/Child GridViews.
i want to set my button visible=false in the child gridview if data is not exist.
i try this:
Protected Sub gv_child_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#FFC080';")
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='';")
Dim lblitemid As Label = CType(e.Row.Cells(1).Controls(1), Label)
Dim lblphoto As Label = CType(e.Row.Cells(11).Controls(1), Label)
[Code]......
but it does not working. the button is still there.
In a nested GridView (GridView inside a template column of parent GridView). I am binding child GridView to a DataTable in parent GridView's RowDataBound event. this works as it should. But the problem i am facing is in Child GridView's RowDataBound Event, when i try to access e.Row.DataItem property it returns null. I am expecting it to return DataRowView Type. which i will then use to set values of TextBox's.
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.
rowdatabound event is not firing during postback ,What to do?First time pageload I am getting result as expected. When I click checkbox ,which is in grid ,my values which are in other columns get disappeared, that means during postback. How to maintain values in the grid even after postback.note : I did some small manupulation of data during rowdatabound event for the columns which are in the grid.
MenuItemClick event will fire on Page1 and Page2 but not Page3 or Page4. The page will post back but will not fire MenuItemClick event. When mouse hovers over the page1 thru page4 nodes IE status bar at bottom shows javascript:__doPostBack('ctl00$Menu1','\/page?.aspx') where ? = 1,2,3,4. I can delete Parent 1 and page1&2 nodes and page3&4 will fire MenuItemClick. Its as though any child nodes after the initial set will not fire the MenuItemClick event.
I have a nested GridView with id grd_inner. i have to find a linkbutton in template field of grd_inner and add some attributes to it. but its giving me error.
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.
why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
I'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:
[Code]....
Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
In nested gridview, i am finding some problem, i want to show child Grid headers in Parent Gridview. Can anyone tell me that how it is possible? Its very urgent. Waiting for quick response.
I have an Asp.net GridView (populate with a data binding).One of my columns is a ButtonField (obviously with his own CommandName).The *GridView_RowCommand* works perfectly, but if i add a *GridView_RowDataBound* (in which I simply add a javascript confirm) the *GridView_RowCommand* event is not fired in the PostBack.
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:
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:
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?
When a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:
1. The date is defaulted to - 5/17/2010 2. If I erase the month and key the "5" back in the data is not saved. 3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.
I use linq query as below and bind it to listview. I have 2 label control (name,remain).I want to check in code behind if p.count<200 then remain ="Sample text1"if price <300 then "sample text2".I know that I could do it before linq in gridview RowDataBound event
Dim prod= From p In db.products _ Select New With {p.name p.category, p.count} postlist.DataSource = prod postlist.DataBind()
I have a very simple asp.net page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:
