Forms Data Controls :: Databind From A Custom Function Call?
Aug 25, 2010
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 I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...
I need to build an address list gridiview that has 3 search boxes - First Name, Surname, Address. How do i set it up so you can use one of 3 different where clauses? or possible 2 where clauses prior to the databind??
I dont want to search / filter a gridview that has already been databind, i want the search to go straight to the DB if possible.
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..
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 ?
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); }
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 some problem with the custom validtor, I do validate at both client side & server side, and i have noticed that the client side code has been executed when I clicked Submit..
More details:
The page contains some Text boxes & one submit button, and all is client-server validated, the problem that when the end user selects the file path through browse control, the code will auto-fill in the file name textbox, and it gives the option to edit; The code which is doing this in the custom validtor client handler, here is the problem it is on_submit click handler, the script function has been called again....!
I have no idea if this is the correct behavior, But I don't want the script code to be executed when any server events fired... !
I want to execute code written in a dropdown selectedindexchanged event from some another user defined function.
For this i m writing:
ddlMyDropDown1_SelectedIndexChanged(sender, e);
It works when use it in page_load (means the code in ddlMyDropDown1_SelectedIndexChanged is executed) but when i write the same line in another function it gives error "The name sender doesnot exists in current context".
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
I reference a user control in my ListView in this manner:
[Code]....
The problem is that the #Bind command doesn't update the database, but it does so when I paste the code directly into the aspx page (in other words, without the user control involved).
I made a composite control that contains a ListBox. I am using the Composite Control throughout my application but I can not bind the listbox in the Compositecontrol. I have setup a Public get to access my listbox in the composite control.

I've written a custom control that converts datasources into an IEnumerable and then binds the data. This works fine and I have LoadPostData working after postbacks. I can also using a collection to load it. Like adding listitems to a dropdownlist on an html page. This works fine and I have LoadPostData working after postbacks
[Category("Behavior"), Description("A collection of CheckBoxItems"), DesignerSerializationVisibility(DesignerSerializationVisibility.Content), NotifyParentProperty(true), PersistenceMode(PersistenceMode.InnerDefaultProperty)] public CheckBoxFieldCollection CheckBoxItems {....}
Kinda struggling on merging the two. I think when i databind, instead of adding my CheckBoxItem to Controls I think I need to add it to my collection CheckBoxItems and then proced with creating childcontrols. It works the first pass through when I bind to the datasource. When I do a postback my controls collection goes to null. Can anyone point me in which direction to go? Also, after databinding, if I do , MyControl.CheckBoxItems.Add(new CheckBoxItem(..)), the new one doesnt show up.
I'm trying to databind a formview to the following two functions. IODS doesnt like the "of configtype as new"
Public Shared Function GetConfig(Of configtype As New)() As configtype End Function Public Shared Function SetConfig(ByVal configItem As Object) As Boolean End Function
