Forms Data Controls :: Best Way To Determine If A Gridview Row Has A Child Record?
Jul 19, 2010
I have a gridview with a template filed which contains an embedded gridview, which may or may not contain any records. I want to be able to make the master gridview row a different color for those rows whose child gridview has records. My plan is to add a sqldatasource to the page that targets the child gridview table and during the master gridview RowDataBound event I would check to see if there are any records and apply the formatting accordingly.
I have datagrid. i loading data to grid from user control like below
[code]....
when i click the button Show child item. all the child item are displaying except one. for first child item not displaying, but one of parent items is displaying inside child grid.
it seems like previous parents data is loading to one of child record. How can i prevent that?
I am using paging to my gridview (pagesize=4) . now i am in (X) page and i want to get (X+1) page top record or (X-1)page bottom record , how i can get .
I want users to select a record in the GridView and then have that record open up in the Detailsview. How would I go about getting these two tools to communicate?
i have design a web application having suppliers table using SqlDatasource..
i have a master page in my design and other form are bound to a context menu..
Now i have displayed the records in the gridview..all i wanted is after i select a record in the gridview it will display the selected record in detailview from another aspx form..
i was able to create the link to another aspx form but the data that it display is the first data from the gridview not the data that i select.
I have wired an event to handle delete command for my GridView. But I cannot determine which the record's unique key, in my case stored in DOCIDNO field. All I get is a row index, such as 0, 1, 2 which obviously cannot be used to accurately delete a record from database.
Anyone know how to determine which ImageButton was clicked in a gridview when there are multiple Imagebuttons in a row. I am guessing it's gotta be done in SelectedIndexChanged.
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 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.
I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
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'm lost. I have a sub gridview in a gridview. In subGridbiview I have a button. How do I can clicking the button and get values outside the gridview? The subgridview not present the events ...
how do I click on the child gridview and get the values of the parent gridview? no events in the child gridview no number indexrow on the parent gridview I'm lost.
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?
how can i read child gridview with checkbox here is my code
Protected Sub GridView2_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView2.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then
I have a table that have LibraryID and LibraryParentID.
LibraryID int Unchecked Name varchar(50) Checked Description varchar(200) Checked LibraryLevel int Checked LibraryParentID int Checked LibraryTypeID int Unchecked
I want to write a sql to delete the currrent select parent and well as all child record, how can I do that?
Using vb.net/asp.net 2005.I have an inner gridview.The outer gridview is "Authors" and in the inner gridview (GridView1 below) I have to set it up so that the user cannot delete the last book from the inner grid, if they try to delete the last book from that inner grid then I want to show the exception message below.
So I am checking the GridViewRows1.Rows.Count which works great when I have one record (one book) to start with. The problem is when I have 2 books (for example). I am writing out the test statement below and the RowCount is always 2 each time, never decremented, even after I rebind.Editing this now: i realize that my initial logic is faulty because when I rebind my inner gridview I am not specifying which inner gridview so the result is that only the last inner gridview is being re-bound, so I think that I need to get the selected inner gridview and then refresh that...
We have a GridView2 in GridView1 EditTemplate.And we have a button (commandname="Update") on GridView2.When Button1 is clicked GridView1 goes into edit mode and displays GridView2.Now when Button2 is Clicked, we want the cell[0] value of GridView2 to be displayed as Label1 Text on GridView1 and comeout of the GridView1 edit mode.Basically we want to capture gridView2 cell[0] value and display that on Label1 of GridView1.We have written the below code. But we are unsure on how to grab GridView2.cell[0] value and display it as Label1 text.Can someone please assist us with this?Also, we are not sure if we can use rowupdated event for this. Please also guide us which events we should be using to achieve the functionality.
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 am having my first go at a nested gridview within a gridview. I have successfully loaded the data and it displays fine. Within the child gridview I have two textboxes that the customer can change. I also have an Save button. When the customer selects the save button the RowCommand for the child grid executes as it should. However I am unable to figure out how to access the two textboxes.
In the past I have got the row index from e.CommandArgument, established the correct GridViewRow using the gridview ID and the row index, and then used findcontrol to get the textbox
int index = Convert.ToInt32(e.CommandArgument); GridViewRow row = gvGridView.Rows[index]; TextBox txtName = row.FindControl("txtName") as TextBox;
But when working within the Child GridView RowCommand event I am unable to figure out how to gain access to the textbox. The child gridview is not recognized.
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.
