Forms Data Controls :: Dynamic Gridview Submit Data?
Jul 13, 2010
I have a submit button on form and want to read all the values from a gridview and the embeddd dropdownlists within some of the columns of the gridview.The gridview is added programmatically and therefore I use findcontrol to find it and then use it to iterate through the rows:
[Code]....
When i step throught the code the values are coming back as empty strings although they are populated on the form? Some of the columns are dropdownlists also and I am attempting to use findcontrol to get these values also but the are just not finding the ddls (i.e null reference)
If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?
in my asp.net+vb web with access database. i have gridview. i had added a form with submit button to add the data in gridview.
i am using accessdatasource to bind the data to gridview.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim connectString As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:webauth.mdb" Dim con As OleDbConnection = New OleDbConnection(connectString)
[Code]....
even after the data inserted message flshes the data inserted is not viewed in the gridview . when i press F% or refresh tha page the gets displayed in gridview. how can i solve the problem
I have three drop down lists that are all databound to a gridview. When the user selects 1. a school, 2. a house number, and 3. a street from seperate drop down lists, bus stops for that address are displayed in a gridview. Everything works fine. After the user selects a valid school/house number/street combination the gridview automatically displays. I would like to add a "Submit" button and not have the gridview display until this button is clicked.
I'm using objectdatasource to get my data. it works fine. Thecurrentway how it works. When the page opens it loads the gridview.but I don't want this.I would like to load the gridview after I press a submit button. so infact after postback...I tried to remove the select Method in aspx and set programmaticallyin the submit button eventhandler but then I get an error thatSelectmethod is not set.Can someone advice me how I can load the gridview usingobjectdatasource after pressing a submit button?
I am facing certain problems with the data formatting in GridView when the data is bound dynamically to it.
I have a DateTime column and want to only show Date from it and not the time.
Another Decimal type column which accepts decimal upto 4 places, I want to show decimal upto the places defined in the particular value (don't know how to put it in the correct way, but here is an example of what I want).
i.e.
1.0000 should be displayed as 1 after the databound in the gridview.
I have a gridview, where I set the columns based on the columns in a datatable. I have a class that implements ITemplate, and creates a textbox template field. Everything works good, I can display my grid with the correct columns and headers. The probem comes up when I click a Save button, to save the user input. Of course the page postbacks, and I re-create the columns on PageInit. However, all the data the user entered is gone.
Is it possible to use dynamic query filters with a gridview using a stored procedure as a data source? What I'm thinking of is a search page where there are multiple controls to enter in a search string and a radio button for the AND/OR query filters between the various controls. If not, what would be the best way to allow a user to select an AND / OR with a group of different query controls?
Here is the page I have created thus far using a view and no AND/OR option. I but I can't get it to work with my SP, also listed below:
I have created a Dynamic Grid View, means there will be a dropdownlist, that contains the list of all tables.User will select any table and data present in that table will be displayed in a gridview.
Now in the footer there is a option to add new items. For that i have done upto this.
[Code]....
This dynamically adds TextBox control at the footer where user can provide input.And after Click of a button those data will be inserted in the respective table. how to get those TextBox's Text on the click of a Button ?How shall i provide TextBox's ID to get its Text?
I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .
Textboxes ID are :ACode , ADesc , ASeq DropDown ID is :CPhase Button ID is :AddRowBTN GridView ID is :PhasesTempGrid
Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .
What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .
Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far :
public void AddNewData() { var dt = new DataTable(); if (ViewState["myDatatable"] != null) { dt = (DataTable) ViewState["myDatatable"]; }
[CODE]...
here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...

I want to bind data from database to Dynamic Grid-view Control with textbox and dropdown using dataset.

I am creating a gridview dynamically in a custom control and adding it to a Panel. I set the EnableViewState = true. The problem is that on a page postback the GridView does not seem to retain its values. If I add a GridView through the UI then the viewstate is preserved. The problem seems to occur when it is put dynamically only.
I am dynamically binding dataset to a gridview(No Columns at design time) .I need to show Totals for some of the dynamically generated columns in the footer.
I wanted to create CrossTab o/p as In Ms Access. tried couple of articles based upon coding in C# but in one way or other they could not give me final result. Then I posted here.
muhammedsalimp almost resolved my query. But only problem I am left with is adding a TotalSum to the selective columns in GridView or In SQL.
It can be seen from the screen-shot that columns 1-7 does not require sum but columns after 7 all will require sum as they are the Items passed their now will vary from day to day.
