Forms Data Controls :: Populate A Gridview After The User Clicks A Button?
Sep 16, 2010
I'm trying to populate a gridview after the user clicks a button. In the button_click event handler I'm fetching the info I want to display on the grid. this is the code I'm using to do it...
I have a ListView tied to a DataSource, included in the layout is a Literal control. I want to be able for the user to click the Select button, and then I want to populate the Literal control with some Data. I have it working, but I have to click the Select button twice to get the data to show. My code is below.
i have a gridview with a checkbox in it, when the user clicks the select button i want the checkbox to uncheck... i've made the select button a template and added the following code:
I display a bunch of data using a ListView. In the ListView, I insert a CheckBox control that allows the user to select the items he likes. User then clicks a button i.e. button control.I now need to get the data for selected items underlying data. I could use some help with this. Here's what I have so far:
I have a form free user feilds, some drop down which are populated by a database data and a button. I want to create a new line in a table when the user clicks on the button. the values for this new line will come from the Values (not visible content) of the drop box, the content of the text feild, the user ID that I should get from the connection and the current date... ie, I want do do a INSERT INTO table (userid, dropdown, text, date) values (how do I get the user ID from the session?, how do I get the value from the drop down?, how do I get the text from the text box?, how do I get the current date?)
i am trying to do is set my page up so that when a user clicks on a row in the gridview a hidden checkbox is unchecked... i am new to asp.net but never thought something as simple like this could be so difficult to work out... i've been on it for around 5 weeks now, i started this on my first day of the website, and have actually designed and written the entire site while still trying to work this out... i first did this on the selectedindexchanged event:
Dim cbox As CheckBox = CType(GridView1.Rows(GridView1.SelectedIndex).FindControl("CheckBox1"), CheckBox)
If cbox IsNot Nothing Then
If cbox.Checked = True Then[code]....
problem is the above code throws up errors...! once i take out the where clause it unchecks every checkbox and writes it back... is there a way i can say just uncheck the selectedrow checkbox and update that one row???
i'll admit there are better ways of doing this, and i'm sure the above code is a little messy,
I am looking to enable/disable controls (TextBox, DropDownList, etc.) in a GridViews template column based on the users specific access level when the user clicks the edit button. I have tried the following two methods:
I am trying to trigger a update planel when a user clicks on an button on a GridView. Once the button is pressed the id of the record gathered and then more information will be gathered and sent to lbl.Text in updatePanel1.
I have a few gridviews on my page. Each gridview row click drives another grid. I need to keep the gridview rows highlighted as the user clicks through the grids. So it is eazy to figure out which rows are being selected on each grid. How can I do this.
I want to reload the page when the user clicks on the back button, from a particular page.Say for example there are three pages:
Page1.aspx,Page2.aspx,Page3.aspx
I want when user move from Page2 to Page3. When he clicks on "Back" button on browser page shld load I have tried adding a onload function JS in Page2 it works out. The issue is identifying user is coming from Page3.
I am changing a vb.net windows form program to browers application using asp.net and code behind vb.net. The form has a textbox for a date, currently when user clicks in the textbox a calendar pops up to force the user to select from the calendar. How do I do this using asp.net/code behind vb.net.
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>") $(this).attr("src", "images/minus.png"); }); Server Side "BindData"
I want to disable a button when ever user clicks on that. My button present inside the Updatepanel control AJAXI tried with the OnClientClick="javascript:$get(btnUpdate).disabled=true;" button is disabling but that is not calling btnUpdate_Click() server side logic. Please suggest me how to do this.I need to disable button when ever user clicks first time and I need also btnUpdate_Click() logic please adavice me.
So I am using a simple GridView control to display a table containing Sender_ID, Subject(hyperlink), date . When the user clicks on the subject hyperlink, another page with the Body should open. This page should also contain a Back button for navigation.

trying to merge two sets of data from a SqlDataAdapter and an OleDataAdapter and then populate a gridview on a button click. If I run just the SqldataAdapter on its own the grid populates as expected. This also applies to the OleDataAdapter. The problem arises when I try to merge the two. I get an empty table, hence dt3 is not populating. The code i'm using is below.Does anyone know why this doesn't work?
I've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this
