Data Controls :: Complete Dynamic Gridview For Feedback
Feb 26, 2013
I want a gridview for feedbcak process by students about their teachers. I need to render teachers image in header row (that,s also dynamically based on previously selected teachers), and dynamically selected questions for feedback in the header column. In the remaining cells I need star rating control to rate the teachers on respective question.
I also wanted the functionality so that teachers images i.e. header row remain in it's position while scrolling but I got the same from your previous post.I also want some hints on how to store the rated values in database.
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 database table I have ID,FirstName,LastName,Address fields.I have bound the FirstName,LastName in Gridview with Eval Method.But have not bound the address coz I m not dispalying address.Now there are textboxes below the gridview which gets filled when I click the edit button in gridview with values in the gridvoew row.I am getting the FirstName and LastName (using find control in rowcommand) but not the address.How can I get the address
I'm using a GridView control, using the Northwind database as a sandbox.
I have allowed editing of rows using AutoGenerateEditButton="true" and that all works fine. The book I'm using for reference the following code behind for error handling (C#):
[code]...
However, this seems to have no effect upon my label text, leading me to believe that the exception handling snippet won't work either.
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"]; }

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 have a dropdownlist with tables. if i select the table, based on the columns the gridview displays.
One table contains 9 columns and other contains 40 columns... for example....see the below.
Insert/Edit RoleUID RoleID Role Desc ....etc columns
Here RoleId, role are mandatory fields... i am making those two with "*" red color. but if i click on the "INSERT" then i need to get a alert msg that the roleid is mandatory.. you should enter in interger value, and if "role" is null then same like "Role is mandatory... plz enter character value"
I don't have any template fields in the gridview. i make autogeneratecolumns=true in my grid.
I need validation for the dynamic gridview cell... where there is no columns fixed...
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.
How to read values of asp: table in grid view after binding.
I want to get values one by one in label in for loop and read values of table row one by one.
Like if i put check box in gridview and the row which is selected , i want to read value that asp:table in gridview.
How I bind grid, code attached.
Private Sub gvTransactionsBind(ByVal qry As String) Dim adp As New SqlDataAdapter(qry, ConString) adp.SelectCommand.CommandType = CommandType.Text Dim ds As New DataSet adp.Fill(ds) gvTransactions.DataSource = ds
I want to bind data from database to Dynamic Grid-view Control with textbox and dropdown using dataset.
I have successfully inserted data to database using this code but now i want to fetch inserted data to same grud view control. i have tried following code. but not getting ans.
SetInitialRow(); string ID = 101; foreach (GridViewRow row in Gridview2.Rows) { string str1 = "Select * from VendorInvoiceDetails where Invoice_ID='" + ID + "'"; DataSet ds1 = GEN.GetDataByQuery(str1);
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 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)
I have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.
EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole = new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi is the webform code behind partial class. CheckBox chk = new CheckBox(); chk.ID = _columnName; chk.DataBinding += new EventHandler(chk_DataBinding); //Attaches the data binding event. chk.AutoPostBack = true; chk.CheckedChanged += new EventHandler(ealmsapprole.Dyn_CheckChanged); container.Controls.Add(chk); chk.Enabled = true; This is the code for the event Handler internal void Dyn_CheckChanged(object sender, EventArgs e) { string err = ""; try { if (lblAppID.Text != "") }
that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.
