Forms Data Controls :: Datalist Passing Variables With Onclick Event?
Jan 22, 2010
I have a datalist control that is querying a accessdatasource for information that populates the results based on w/e is typed in a textbox. I can't figure out how to pass the information that is populated in the datalist to another page when a button is clicked (inside the datalist item template).
I was able to peform this in Detailsview with a hyperlink using the following arguments:
DataNavigateUrlFieldsDataNavigateUrlFormatStringBut this seems not to exist in Detailsview. Could someone point me in a direction on how to acomplish this?
i have a linkbutton inside the Datalist control while i am clicking i would like to pass the ID value of the corresponding Link button. How can i pass the id value for the onclick function?..
First up i would like to apoligize for these questions that are proable realy easy. I have been put on the spot by my boss and have been told to change all my php to asp.net c so it can go in this new cms i have at work. I have just spent the last 18 hours trying to get this to work and im geting a little desperate.
Ok so my current issue is that i dont know how to add html formating to a result string i pull out of my mysql database. I have my result sheet pulling into a gridview, what i want to do is put some information drawn from each row in the gridview out side of the <Tr> tag. Is this possible? But within the Table Tag second issue is it possiple to feed data into a page and then run a mysql query like i was doing in php.
I need to be able to evaluate the text value of the template button or pass date from the dbDateOpened colum when the button is pressed. Either direct I have tried gives me an compile error. With the current configuration I get this error. "Object reference not set to an instance of an object."
Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
I have been trying to add and OnClick event to a Hyperlink. The problem is in both FindControl, they are not populating the hl and reportId variables. I have added the following to the RowDataBound method.
[Code]....
When clicked the client side addUsage OnClick event will pass the the variables to a Generic Handler as parameters.
I have a DataList control that I use to display a list of words.
[Code]....
When a user click on any of these words, I want to display the details of this word's in my ListView control that is on the right side of the DatatList control. The ListView control is setup to use a SQLDataSource control. I want to use the SqlDataSource1_Selecting method to grabe the ID from the DataList control but I'm not sure how I grabe the ID or how to setup the DataList to send the ID over.
How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)
For an image gallery page I am trying to bind data to an image control. Here is the control within the listview control:
[Code].... [Code]....
Radopen is a function from [URL] and works fine. I can also display thumbnail images fine too. However, when I click on a thumbnail I get no popup, nothing. When I replace [Code].... with [Code].... It works too. For some reason I cant bind data though.
I have a checkbox inside a repeater like below..I'm having trouble figuring out how I need to tie the onclick event to a javascript function..I know I need to use somthing like
butSubmit.Attributes.Add("onClick", "return confirmSubmit();") but Since my checkbox is inside a repeater and I'm using master pages. I'm not sure how I need to use the findcontrol to so I can call the Add method?
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.
I am having troubles making the code run. I have a web page with a gridview and a checkbox. I would like the button when selected to pass the category id. I have managed to get it work without paging. Once the paging kicks in see below, I am unable to run the code. see below.
I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button Data Data Button Data Data Data Button Data Data Button Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
am designing report using gridview in which i want drill down report, i.e. when i click a cell of gridview which contains value from the database. i want a new gridview to be populated with detailed report, which should be generated by passing some values from parent gridview.
i have written some code for the same,but in the code the event is not getting fired.
code is:
in gridview rowdatabound protected void gvHdr_RowDataBound(object sender, GridViewRowEventArgs e)
i have two nested gridview inside an update panel. there is a button called btnPhoneEdit inside the child grid view. when the button gets clicked, it do cause partial post back as expected but it fails to invoke btnPhoneEdit_Click.
here is how my grid view looks like and how i add my custom data source to both parent and child grid view. [Code]....
I have 4 checkboxes. I need that user should atleast select one checkbox and then submit the form. But the onClick event of the button is not working. I already have events for button click. See the code for reference.
I am using datalist control on Default.aspx. In that datalist control I have ASP Link Button and the data is fetched from the Database while loading the control. Now, When my user clicks on that particular Link Button, the data associated with it should be shown on the next page. Which event shall I use? How do i select the values that I would show on the next page?
I am writing what i will call a survey system. The surveys will consist of a series of questions, split into sections. The survey definitions will be stored in a database. The questions can be of various types, that have different input methods and validation (e.g.textbox, numeric textbox, selectlist etc.) I am creating a set of user controls that map to different question types. I would like to completely abstract the survey rendering logic from the, survey definition logic. The way i thought i would do this is to use a dumb rendering control that simply takes a collection of controls and renders them out in a for each loop a super simplified version of what I am doing.
This works in the sense that the correct controls get added to the place holder,however nothing renders. Presumably this is because it does not have the markup in the asxc file.
If i do something like this
private void RenderControls() { foreach (UserControl CurrentControl in this.ControlsToRender) { MyPlaceholder.Controls.Add(this.LoadControl("path to ascx file") } }
It will create the correct number of controls, but i don't want to instantiate the controls here because i would need to to set various properties based on cconditional logic i want to abstract away from this pure rendering layer.
what i want to do is instantiate the controls else where, set the relevant properties and then simply pass a collection of these into the rendering control to render out.
Is there a way to do this with user controls? Would i have to create custom controls instead?
i am developing an ASP.NET website, i have a datalist that contains an item template with hyperlink in it, i want to access the hyperlink clicked i tried "SelectedIndexChanged" event, i don't know what to do. here is the code <asp:DataList ID="DataList1" runat="server" DataKeyField="album_id"
