I am working on some project which is in classic ASP.NET, but I need to migarate that into MVCRight Now I am having a page with one button and gridview which get fill on clicking the button. Gridview has the functionality like EDIT, DELETE, Paging, OnRowCommand Event. How should I perform this page through MVC. I know gridview can't be used in MVC, so what's the alternative of that.
View 3 RepliesI am using a web form in vs2010 and in my form am having a gridview with button on footer. I have written the code to create a new row while click the button. If I click the button i got the following error
"unable to cast object of type 'system.web.ui.webcontrols.textbox' to type 'mysite.textbox"....
Below is the button click code.
private void AddNewRow() {
int rowIndex = 0;
if (ViewState["CurrentTable"] != null) {
dtCurrentTable = (DataTable)ViewState["CurrentTable"];
DataRow drCurrentRow = null;
if (dtCurrentTable.Rows.Count > 0)
[Code] ....
Currently i have my buttons labelled and positioned as follow :
x0_y3 | x1_y3 | x2_y3 | x3_y3
x0_y2 | x1_y2 | x2_y2 | x3_y2
x0_y1 | x1_y1 | x2_y1 | x3_y1
x0_y0 | x1_y0 | x2_y0 | x3_y0
What I'm trying to do is fill the buttons name programatically. So far I will get X and Y values and i need to change the text of that button at that position.
I know it's possible to do x0_y3.text = xxxx for each position but this will take years, i'm looking for a solution using a loop or some other technique to easily replace the text values. and the buttons are under an updatepanel.
ex :
GIVEN : xx=2 yy=2
ex. WHERE IT IS "x" & xx and "y" & yy
REPLACE TEXT WITH "hello"
I tried something like this, but it doesn't work with the updatepanel for some reason, but it works fine if i use a simple panel
Code:
For Each c As Button In UpdatePanel1.Controls.OfType(Of Button)()
MsgBox(c.ID)
c.BackColor = Drawing.Color.Yellow

I have a gridview which should populate based on some criteria that the end user selects.
To enable the user to enter the required criteria i have added some Web Controls like Textbox,Drop Down Lists etc.
My code behind for getting the data is as below

The Headertext of my column only changes after clicking the button a second time round, why is this? I obviously need it to work on the first click.

i have a table containing multiple agents , another three containing events ( three types of events , each category in a diffrernt table) organised by each agents! , i have to figure out how to fill a grid view that regroups a summary of the activity of every agent ! for example :
AGENT EVENT1 EVENT2 EVENT3
agent1 3 0 2 agent2 4 4 1
agent3 5 4 2
that means that the agent 1 have organised 3 EVENT1 0 EVENT2 and 2 EVENT3 ....
i have used the count(*) clause to fgure out the number of rows in table events referencing to each agent (group by) but it seems that value 0 is not returned by the clause , so i'm having a problem getting the exact values!
secondal , i have putted two calendar that will fix the beginnig and the end of the summary , but it seems that the end day is not included : it says 18/01/2010 00:00:00 and i have some events planned in 18/10/2010 14:10:00 so they are not counted !
I have been trying for ever to hide a column in gridview using the following code,
GridView1.Columns[6].Visible = false;
but the debugger says that index is out of range, the number columns when runnung Columns.Count is zero
even though I have a table with data it says that there are no columns
I got a function to load a grid view and works fine. Then, I got a button, when click, I wanted to add a new row into the grid, what I did is I add a new to to the dataset and rebind the dataset to the grid view.
The problem I faced is that is it able to add a new row, but it only shows ONE column only, which is the most left column.

how to remove the record from gridview when i click on delete button in vb.net ?
View 1 Repliesim now created a function where i can import excel file to be displayed in gridview and then insert the data from gridview into database.
It is running smoothly until i copied the page into another file. Suddenly, when i try to display the gridview, it does not appear.
I've try copied everything exactly the same like the original one, but still failed.
Does anyone have experience like this before?
This is the snippet my code : default.aspx.vb

On my Form I have 2 gridviews namely; gvCRSearch (that displays search results) and gvCRView (that displays all the change requests raised).. Now, when the records are more than 10 in gvCRSearch it automatically creates a navigation number i.e., 1 2 3 Same thing happens to gvCRView
What is wrong is that when I click the navigation i.e., ( for example 2) on gvCRSearch
1) the gvCrSearch becomes visible = false
2) the gvCRView if it has a navigation number is moved to 2
So the effect is seen the next view (gvCRView) and the gridview (gvCRSearch becomes invisible)
the asp is as shown;
Code:
<asp:GridView ID="gvCRSearchView" runat="server" ShowHeader="True" AutoGenerateColumns="False" DataSourceID="CRSearch"
BackColor="White" BorderColor="#600000" BorderStyle="Solid" BorderWidth="2px" CellPadding="3" Font-Size="89.5%"
ForeColor="Black" GridLines="Vertical" AllowPaging="True" PageSize = "10" AllowSorting ="true" CssClass = "MainGridView">
<Columns>

In a webform I have two textbox (txtDNI and txtAPE), 2 buttons (b1 and b2), 1 gridview (myGV) and 2 functions (dt1 and dt2) that return a DataTable txtDNI will be a parameter for dt1 function and txtAPE will be a parameter for dt2 function
DNI [_______] (b1)
APE [_______] (b2)
[NOM |APE |DNI |DIR |OCUP ]
============================
[ | | | | ]
[ | | | | ]
[ | | | | ]

[ 1 2 3 4... ]
When I press b1 myGV will be fill with the dt1 function's datatable and when I press b2 myGV will be fill with the dt2 function's datatable myGV allows paging=true and when I press the next index (2 or other) It appears a PageIndexChanging error. So the pagination isn't automatic and I have to code the PageIndexChanging event When I use a ObjectDataSource and I connect it with myGV the PageIndexChanging error dessapears and the pagination is automatic The problem is the ODS only have a one selectfunction (dt1 or dt2) but not both and the configuration is on design time
The same happen with the PageIndexChanging event where I fill myGV again (with dt1 or dt2) and set the new index (myGV.PageIndex = e.NewPageIndex) and What is the problem?? ... the problem is, for example, when the user erase txtDNI and change index of pagination ... the PageIndexChanging event is fired and call the dt1 function but the txtDNI(parameter) is empty and occurs an error, the function returns an empty datatable and myGV is empty too for avoid this I create viewstates variables for each function, so I have a 2 viewstates and fill them when the user press b1 or b2 When user press the pagination, the PageIndexChanging event catch the viewstate variable and convert it into a datatable and the problem of the automatic pagination is controled The problem is I don't have 1GV in the webForm I have 5GV in some pages... and I try to avoid...
1. all the code in the PageIndexChanging events of each GV in the webform.
2. use the viewstate variables
I don't want to databind a gridview, I want to be able to add rows myself within c# code. I can see there is a GridViewRow object and wondered if I can use this to add/remove rows as required?
