Forms Data Controls :: Put The Call For The Update Function?
Apr 13, 2010
I have GridView with my own Edit/Update functionality.
What is the best place to put the call for the update function?
I know that placing the Update button will have the click event.
I have extra textboxes and other controls placed on the edit-mode that will have me to find them. So, what is the best place to put the call for the update function that will let me find these controls to be updated?
Is it via GridView_RowCommand and the use of CommandName ?
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.
I Getting A Problem In DataGrid's ItemDataBound Event. I Am Calling A JavaScript Function In DataGrid's ItemDataBound Which Retrun The CellIndex And RowIndex Number On Which UserClick After That I Am Re-Binding The DataGrid With jQuery Function After That ItemDataBound Event Not Working. I Want To Call The Same Function Again. Is Their Any Method To Call A Server-Side Function On ItemDataBound Event Except Client-Side Function..
function SetScrollEvent() { window.scrollTo(0, document.body.scrollHeight);}
I update update panel from server side like below.
protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e){ //HiddenField hiddenId = e.Item.FindControl("hiddenId") as HiddenField;Label lb1 = e.Item.FindControl("Label2") as Label; //Button bt = e.Item.FindControl("Button2") as Button;if (e.CommandName == "myclickevent"){ // your codes here...SqlConnection conn = new SqlConnection(constr);SqlCommand
[CODE] .....
I use repeater and repeater have button on button click i update the update panel. now where i have to call the javascript function so that it execute after update panel fully loaded. I want to call javascript function after page fully loaded.
May I know how can I call my "OtpLeaveDefineGridView_RowCommand(OtpLeaveDefineGridView, ??? );" at other function. I really don't know what should I put at "???" for the GridViewCommandEventArgs.
i have an datalist within that i have a imagebutton while clicking this i just call an js function, here when i pass the identity column value from hiddenfield then js function calls good, if i pass the Imaagebutton url then raise an error as "Error on Page".
here is the code
function onGridViewRowSelectedZoom(imagePath) { alert('hai'); alert(imagePath); }
in datalist templatefield, i want to bind an imagebutton's visible property. the scenario is .. it is a picture comments page like one in facebook. if its your own comment, the delete button is shown, otherwise not. the problem is .. for the imagebutton i want to set visible = false, if the user logged in is the same user as the one who commented. how can i do that ?
currently im using this code on datalist databind event. but the label is returned as null
public bool set_visibility() { Label lb = DataList3.FindControl("Label7") as Label; if (lb.Text == Session["user_id"].ToString()) return true; else return false; } findcontrol dosent return the control.
So, as it may look i want to call MyFunction defined by me with the Id parameter of current object that repeater displays. This is obviously not working.
created treeview dyamically. I wanted to invoke a javascript confrim when a node is clicked . it should give him a popup saying are you sure you want to delete. if yes then call the file which is set in the navigate urlif user selects no, they nothing should happen.
TreeNode ActTNNode = new TreeNode("<span onclick=""javascript:confirm('Are you sure you want to delete);"">Delete</span> ");
I am trying to build a site that will display a word ("Synset" in my code) from a "function call", (ultimately the word will come from another database but I'm ignoring that part for now). The user will click one of 4 radio buttons deciding if the word is "positive", "negative", "neutral", or "can not be determined". Then the user clicks "Save" the word is saved a MS SQL database, the function is called displaying a new word and the process is repeated.
So far I have been able to get this to mostly work by using the code below. The problem is that the function is called and the correct word displayed when the page loads the first time, when I click a radio button and then the "Submit" button, the word and value from the radio button are saved to the database but then no new word is displayed. The text just disappears. The new word is created, as I can see that new words are saved to the database when i click submit.
I'm thinking the issue might be because I'm binding the text attribute of the label I'm using to display the word to the sqldatasource, because it's probably trying to display the text from the database?
I've tried putting the code that gets and displays the new word in FormView1_PageIndexChanging() and submitButton_Click() and neither work.
I've tried to just call Response.Redirect("Default.aspx") in submitButton_Click() and this displays the word but nothing is saved to the database.
I have a gridview and am using the Edit - Update function to update one field in my gridview. I have the textbox appearing as I want it and am able to update the data for that cell.
The problem I have is refreshing the gridview after the update. The Update and cancel are still shown instead of the gridview refreshing back to the Edit statement after the update.
I want to create one web application in which I will click on cell of a gridview after that one javascript file will be called that will again call a asp.net web page

(//// Or simply what i want is to do the same calcultions onthe fields while perfoming an update operation.. //).

I have a text box that I am reading mulitple employee names into. If the user enters a name that does not belong to an employee I want to cancel the item_updating function. Here is my code:
Dim RECIPIENTS() As String RECIPIENTS = RLIST.Split(";") Dim NAME As String [code]...
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" > hi ihave this functin in .vb file Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click end sub
how to jquery call a other call function other class is not static
[WebMethod] public static bool Verify(string username, string password) //Do your logic with username, password here //I am just checking with admin/admin credentials Console.WriteLine("Ritu"); [code]...
<WebMethod()> _ Public Shared Function GetDate() As String Return DateTime.Now.ToString() End Function
I need this to populate the inside of the div with the string returned by the GetDate() function. I think this should use code similar to this:
[Code]....
I've pulled this example from this site: [Code]....
However, I simply cannot get it to work. Nothing happens. This is just a regular asp.net web project. I haven't done any sort of Ajax-enabling business other than including script tags in my markup to reference jquery.
Here's what the firebug console tells me when I click on the div:
POST http://admin/Default.aspx GetDate 404 Not Found -18ms
Edit: Note: test.aspx/GetDate must match your aspx page name and function name!
