Pass GridView Cell Value To Sub Routine In VB.NET?
Feb 15, 2011
I have a GridView with Cell 0 containing the ID that I need to pass to a Public Sub.
I cannot figure out how to pick the value from Cell 0 in order to pass it to the Sub. I have tried experimenting (see the Dimmed EventID below) but have failed. Here is my code:
Protected Sub gvAppointmentsCalls_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvAppointmentsCalls.RowCommand
Dim EventID As String = gvAppointmentsCalls.Rows(e.RowIndex).Cells(0).Text
If e.CommandName = "gvAdd2Outlook" Then
Send_iCal_Call(EventID)
End If
End Sub
If I type the value directly e.g. Send_iCal_Call(123) then it works perfectly.
Public Sub Send_iCal_Call(ByRef Event_ID As Integer)
' My code in here
End Sub
i have a GridView in my page that is associated with the database table "Blogs", GridView is showing all the table data correctly, i have added a link button column in the GridView, which is not defined or constructed in the Database table... I want that when i click on the button against a row in the button column of the GridView, the B_Id column cell value is passed to the other page, and control goes to the other page.
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
The code below iterates through directory, then I collect image titles and want them to be populated in gridview. code in bold is not working well, gridview is only filled with the last image in list.
how to fill gridview cell-by-cell only with available amount of images?
In my Website, I have a gridview which has datasource dynamically bound from database table. Requirement:
Now I want that when a user clicks in a cell of the gridview it becomes editable and he can edit the cell values and update the database accordingly. I dont wish to use the in-built edit, delete and update buttons of gridview. How can I do that?
I'm trying to do a number of large queries in the same routine, and have a label in an updatepanel update after each one. I must be doing something wrong, however, because whenever I fire up the routine, my label won't update until the last query is done. Isn't it possible to do UpdatePanel.Update multiple times in the same routine/event? This is the code I'm using:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click lblStatus.Text = "Busy with task 1" UpdatePanel1.Update() LongTask() lblStatus.Text = "Busy doing task 2!" UpdatePanel1.Update() LongTask() lblStatus.Text = "Done!" UpdatePanel1.Update() End Sub
Private Sub LongTask() conn = New SqlConnection(connstring) conn.Open() cmd = New SqlCommand("Select * from very_large_table", conn) cmd.CommandType = CommandType.Text reader = cmd.ExecuteReader() End Sub
When the form loads, the lblStatus is emtpy. When I click the button, I see the page loading until it displays 'Done!'. I don't see the other texts. This is the page source:
I have a web form with lots of code behind a button. I want to create a class, put all the code form the button into the class. But how do you call routines in the button from the class?
In my application, there's a module that displays a user's assignments. Sometimes these assignment descriptions are pretty long that's why I display up to 500 characters of the description. However, because I use an HTML editor in the app, if I blindly grab the first 500 characters, there's a good chance the description will look very funky due to missing HTML tags. So, I first need to strip off all the HTML tags, then grab the first 500 characters. Before I re-invent the wheel, I wanted to see if someone else has already tackled this issue and would be kind enough to share his/her code with me.
My webform has 4 fields: Food Rent Utility subTotal
I'm using DynamicPopulateExtender for Food, Rent and Utility to update subTotal whenever there's a value enter.
Question #1: Do I use customScript or ServiceMethod that link to the function below
Protected Function UpdateSubtotal(ByVal nEntry As String) As Integer Dim oldSubTotal = Eval("Subtotal") 'Bind("Subtotal") = oldSubTotal + Eval(nEntry) <--- I know Bind("Subtotal") don't work because Bind is not declared
End Function
Question #2: How do I update Subtotal value on the webform?
I'm looking at automating some reporting that I'm going to be generating. I want the reports to be generated and emailed at a particular time every day. These times will vary, and so will the types of reports.I was wondering if there were any better solution to creating a routine with a timer that executes at a set time every day? If I include this class and routine in the Application_Start of my Global.asax, will it always be running, or is there some awesome EventListener that I'm not aware of?
I am writing a web application and one of the save routines calls another sub routine as passes two parameters byref. the sub routine gets the data required and assigns it to the passed parameters.
When I look at the results in the main sub the passed parameters are not set, why?
Code: Private Sub GetSiteDefaults(ByRef sCleanerCode As String, ByRef sCheckerCode As String) Dim sqlDASites As SqlDataAdapter Dim sqlDTSites As DataTable Dim sqlDCData As New SqlConnection sqlDCData.ConnectionString = conStringHQ.ConnectionString.ToString sqlDCData.Open()
in .vb file, in a class i have created a button control, assigned its ID, and other properties.
In code behind file of a aspx page i have created object of that class.Run the page and browser Button control is coming. Now i want to do something in its click event.
But i am confused how to define that one, since presently there is no any button control instantiated.It is getting instantiated at the runtime.So, how to define its click event or any other events ?
I am using a adapted version ofhttp://www.mikesdotnetting.com/Article/45/Programmatically-accessing-data-from-DataSource-controlsDon't we need something like a closing-routine / close connection command after getting data from the database?If yes: What is the correct closing command?
That doesn't make any sense at all but what I mean is, if you've got a button for example which takes say 10 seconds to complete whatever is in the button click routine, and somebody else on a different computer clicks the same button just after, is it possible for that second button click routine to wait until the first one is complete? And most importantly is it something fairly simple to do? I'm sure I accidently found some information on this when searching the web for something else but I can't remember what I was searching for before and can't find it now
i want to show selected row of gridview into textbox then we can change these value then we click update button then these value add into selected row., this row show the update value not previous using jquery . following my code.
<script type="text/javascript" src="~/Scripts/jquery-1.10.2.js"></script> <script type="text/javascript"> $(document).ready(function () { // function Edit() { var par = $(this).parent().parent(); var id = par.children("td:nth-child(1)"); var name = par.children("td:nth-child(2)");
I have uploaded a excelsheet to datatable and that datatable is bound to gridview.there is a save button present,i want to click the save button and all the gridview data will save in database.but that gridview has no boundfield or templatefield.
Alright, so I have a Gridview which is bound to a stored procedure. The stored procedure uses cross tab functionality to count customer data / types, and then display it like this ...
Code:
[code]....
Now this is where I'm stumped ... each data cell (or cell that displays the count of data for that column / row), need to be a link, and upon clicking that link, a pop up or something will bring up another gridview or list listing all those clients or customers. For example, if you click on row 2, cell 2 (519), then it will open a gridview or list of all 519 of those clients. This basically means each cell will have to represent a different query, unless I use dynamic sql somehow... Does anyone have any idea how I might be able to accomplish this.
Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:
How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I have a GridView, in which the width of each column is dynamic and changes depending on the dataset. I need to get the width of each column for use in my PDF exporter, but the column/cells width is always '0', presumably because I haven't set the width property.
i need to copy the one gridview cellvalue to another gridview eg: gridview1:
a b c 1 s 2 2 v 3 3 d 4
The Second Gridview Value Should Be
a g h 1 1 2 2 2 3 3 3
but i am getting the last value 3 in each row. My Coding
ArrayList da1 = new ArrayList(); ArrayList da2 = new ArrayList(); int a1 = 0; int a2 = 0; int id=0; foreach (GridViewRow row2 in grv2.Rows) { foreach (GridViewRow row1 in grv1.Rows) { a1 = int.Parse(row1.Cells[3].Text); da1.Add(a1); da2.Add(a2); foreach (int ir in da1) { if (id < ir) { row2.Cells[1].Text = row1.Cells[1].Text; } } } }
