Templatefield CheckBox in gridview acting strange

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :ASP.Net
I have an ASP.NET page that contains a gridview. I have to create columns dynamically based on a datatable, some field type info and some header texts. I do that by creating templates. It created the grid fine and all looks good, however when i click a checkbox and the checkedchanged event fires then something odd happens The first time i click its fine and i get the expected values in the event But the second time then the event gets fired with the values from the first time and then again with the values from the checkbox that i actually clicked.. The third time the event gets fired 3 times, first 2 times with the old values and the third with the correct value. And it just keeps going like that Furthermore Let us say i have 10 checkboxes that are checked when i uncheck one the checkedchanged event fires but if i check it again the event doesnt fire and also if i have unchecked 3 checkboxes(and get the extra events) then if i check one of them again i get 2 checked changed events fired for the ones that are still unchecked but no event gets fired for the box that i checked  so now im just baffled   See pastebin link below for code: http://pastebin.com/stcwqsYa

disable autopostback of checkbox inside of GridView during SelectedIndexChanged of ListView

Hi, I hope my question is clear: I have a checkbox placed inside a gridview: <GridView><asp:TemplateField HeaderText="Driver">   <ItemTemplate>       <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' />   </ItemTemplate>       </GridView> For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked. Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired. How could I disable the autopostback of the checkbox during the listview item changed. Thanks in advance

Dynamic templatefield disappear during gridview rowcommand

Hi,   I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear. To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again. I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.   Any ideas?

gridview checkbox sorting not working

Hi All,I have a grid view which populates data just for viewing purpose(report) . One field shows the Active/inactive status for which I am showing a checkbox..if data in database is 1 then the checkbox will be checked otherwise it'll not be checked.

Please help and suggest some scenarios/links so that I can achieve sorting for the checkbox column also.Thanks in advance.

WebRequest acting very strange

hi all, I am using a webrequest to call a search from a Google Mini appliance.  During testing we noted that if two people submit different queries at almost the same time the web request routes the wrong query to the wrong user. For example me and another worker are sitting beside each other with laptops.  We each hit the search page and enter different queries and hit enter at almost the exact same time - whoever hit enter first usually gets their results sent to the other users computer request. Here is my code - any way to do this either without a web request or keep the webrequest in the context of the current user?   string client = "client=default_frontend"; string output = "output=xml_no_dtd"; string getFields = "getfields=*"; string siteCollection = string.Format("site={0}",Request["site"]); //perform the search string reqURL = string.Format("http://search.xxxxxxxxx.com/search?{0}&{1}&{2}&q={3}&site={4}", client, output, getFields, Request["q"], Request["site"]); ///TO DO : Determine what is happening with the web request when two requests. /// happen at one time. WebRequest req = WebRequest.Create(reqURL); Stream objStream;
