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:
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?
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.
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.
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 (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'.
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.
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:
Anyway, on the inner grid I am allowing the user to delete rows.However when the page posts back I am unable to reopen the row that was opened. I have tried the RegisterStartupScript, etc. in the code behind but am unable to trigger the event. I have tried the code behind to find the row that is expanded but that was unsuccessful also.How can I have the row expanded when the page posts back?
URL....When the user creates a new child record (2nd gridview) how can I ibsert a field from the parent level (obviously from the line where they clicked from).
I have followed your Nested level gridview and found it working, but i want add a button in the child element(from your example i will have a btn in Product grid and it should get contact_id (parent datakey value as well) ),as i need to update in database.
i have a parent gridview,It has child gridview in every row.The edit and delete event of this child is working is fine.When i add data to through child gridview with empty data template.i can 't find the value of the parent contril id.
gvProductFeatures is the chid gridview... protected void gvProductFeatures_RowCommand(object sender, GridViewCommandEventArgs e) { try { if (e.CommandName.Equals("EmptyAddNewFeature")) { GridView gv = (GridView)sender; if (gv != null) { // here i need find the appropriate control id from parent..how?? int intIndex = Convert.ToInt32(e.CommandArgument); Label lblEmptyGroupPK = (Label)gv.Controls[0].Controls[0].FindControl("lblEmptyGroupPK"); TextBox txtEmptyFeatures = (TextBox)gv.Controls[0].Controls[0].FindControl("txtEmptyFeatures"); } } } catch(Expection ex) { } }
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.
I have a Parent gridview with a nested gridview. Edit on the parent works fine. On the nested child gridview, when I click the edit button, the line goes into edit mode, but the parent row collapses. To correct I added javascript to call the javascript function that is used to expand and collapse the rows. It is located in the RowDataBound event of the parent gridview.
Based on the code samples I have, the way the process should work when the edit button is clicked is the RowCommand and then the RowEditing events for the child gridview are supposed to fire, followed by the RowDataBound for the parent. The child events are firing after the parent though. This wouldn't be a problem except that I am retrieving the parent line that holds the child record being edited so that value can be fed to the javascript function to expand the row. How can I fix this or work around it?
since APS.Net 4.0 I have a curious problem with an event.
There is a FormView and inside of the EditItem there is a GridView. In the Footer of the GridView I put Controls for inserting records.
But when I fire a markup defined RowCommand of that GridView then the same event is getting fired for the Parent FormView. First I had 'Insert' as the CommandName and so I was getting the Error that my FormView had to be in insert mode to insert a record. Then I changed the RowCommand of the GridView to 'xxx' and I got also the RowCommand 'xxx' at the RowCommand eventhandler of the Parent FormView.
The project was migrated from .Net 3.5 a few days ago, but nothing was manually changed in the code/markup. And the problem was not there with the "old" framework.
[Code]....
Of course, I could simply change the CommanName of the LinkButton e.g. to 'InsertChild' but I would like to know:
I have a parent gridview control and a another gridvew control inside parent gridview.I want to access a column named type in parent gridview inside child gridview.And use the value of that column in a javascript function
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:
