Forms Data Controls :: Add Dynamically TextBox And DropDownList In Gridview On Button Click
Oct 8, 2010
I have Gridview and Button Control on Form.i want to Add Dynamically TextBox And DropDownList In Gridview on Button Click Wich is placed outside of Gridview.
When i click on Button -> One TextBox and One Dropdownlist which contains values bydefault 1,2,3 should bind to gridview. Button is placed outside Gridview.
I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.
To change particular value in a dropdownlist dynamicallyfor exampleif i have a value as Apple in dropdownlisti should chk if that particular values is present or not then dispaly it as "redfruit"
I followed the article Nested GridView Example in ASP.Net using C# and VB.Net ..... It is a great article and very simple to follow. I easily modified it to suit my needs and added several more levels to the nested GridView.I am a VB.net Programmer and I have never used ASP.net or JQuery before.
The data I am using is very large and with the "OnRowDataBound" events, the Page is Pre loading all the data into the gridviews and the Plus/Minus images are just displaying/hiding the nested gridviews. The question is "How to make the nested gridviews populate dynamically?" I want to have the nested gridviews to databind when the plus image is clicked.
I added the below code to the Plus image click Function to execute the server-side "BindData" Function. however I don't know enough about ASP or Jquery to get the GridViewRowData to send to the server-side function.
$("[src*=plus]").live("click", function () { $.ajax({ type: "POST", url: "Main.aspx/BindData", data: '{}', contentType: "application/json; charset=utf-8", dataType: "json", error: function(err) { alert("err");}, success: function (msg) { // Do something interesting here. alert("ok") } }); $(this).closest("tr").after("<tr><td></td><td colspan = '999' width = '100%'>" + $(this).next().html() + "</td></tr>") $(this).attr("src", "images/minus.png"); }); Server Side "BindData"

how to dynamically generate textbox during button click. for each button click i should get the textbox generated along with labes dynamically ,in asp.net using C#
1. When executed I have a "Add Building" and "Click here to add tower" on the page.
2. When clicked on "Add Building" a editable gridview appears when I enter the text and say update.
3. When I click on "Click here to add tower" another button "Add Tower" is displayed on the
page.
4. On this "Click here to add tower" event I have called the usercontrol, where the usercontrol has a editable gridview and a button called "Add Tower".
5. When I click on "Add Tower" a editable gridview should be displayed but the editable gridview is not displayed ,it disappears.
6. Postback is happening ,so I am not getting where and how to handle the postback and even the viewstate
I just don't understand how this is done. I've gone through several questions here and from a few other websites.
Basically, a company will be adding process steps, and I want there to be a textbox with a button next to it that reads "Add another step." Once clicked, a new textbox will appear beneath the current one, and the button will be moved next to the new text box. What do I need to do?
this my gridview data with button's i want as soon as i click the button(Button here is not the Button Web Control) i refer button here as Gridview Button(click me/Gridview Button) the corresponding value should populate my textbox's just trying something in asp.
I have checked this article link here and its good.. What i want is how can i avoid the button.. mean add the row dynamically without using the button click event.. Instead use text changed event..
I'm here again to share a problem that I'm fighting against for days. I'm developing an eCommerce Cart.
Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.
When the customer clicks over the Button, it fires a function that gets the content of the TextBox and do an update on my Database.
It works perfetly when it is done with the mouse click. But I need to fires the update function WHITHOUT the manually click event. When the customer just put the mouse out of the TextBox (onblur event), I want to fires that function.
I got GridView with 2 columns both are Template field with drop down list. What I need to do is someting like when user select course 3/3A/2A/2B , the type column will auto select pratical option dynamically. When select RTT /FTT/BTT , the type column will select Theory option. Can someone tell me how to work on this thing.
I have a rather large formview that asks for a variety of input values (physical totals vs pos report totals). I have created vb code to calculate the differences and subtotals of various types prior to inserting the data so people can check for entry errors.
Its a closing reconciliation form. Here's the problem: If they forget to enter 0 in a field that doesn't have any totals, a big ugly error message displays. I would like to avoid this. I can tell them until I am blue in the face to remember to enter 0 and not leave any blank fields, but realistically its going to happen and I need to handle it in the programming.
I have been struggling to either default the values to zero to start with, replace a null textbox with 0 before the calculate runs...but I can't get anything to really work. What is the best way to handle this?
Here is the aspx page:
[Code]....
And the code behind page with working "Calculate" as long as fields are not left blank (I took out all the test code that made it not work at all)
[Code]....
Finally, the error message I am getting is the following:
[Code]....
I can't seem to find the right combination of programming to account for the "" string to be 0 so that it will add or subtract values in my calculate. I have my sql table setup with default values of 0 so if a field is left blank it will be entered into the database as 0 and not null. It is really just for my inserting of a reconciliation and the running of Calculate Totals to double check their work prior to inserting into the database.
I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.
I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then Dim ddl as DropDownList FillStateList(ddl) e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?
I have a dropdownlisbox , i am changing the selectedIndex by PageMethod(i.e it will change its value and text on checkbox status). At that time it don't fire the selectedIndexchange method but when i click the button it fires(i.e on postback).
